1. Field of the Invention
This invention relates to engine knocking control devices, and more particularly to a knocking control device which is improved so that it can control a knocking strength automatically to a predetermined value.
2. Description of the Prior Art
A so-called "knocking phenomenon" in which abnormal hammering sounds are caused in the engine of a vehicle while it is running is well known. The knocking phenomenon occurs in the case where the load is over a predetermined value and the ignition timing is excessively advanced. This knocking is undesirable because it cause unpleasant noise, and strong knocking provides strong gaseous vibration in the cylinder and causes abnormally high temperature locally in the cylinder, which may damage the engine.
FIG. 1 indicates variations in cylinder internal pressure with respect to engine crank angles. As is clear from FIG. 1, the pressure vibration is caused by the knocking when the crank angle is in the range of from 10.degree. after the top dead center (TDC) to 30.degree. after the top dead center. FIG. 2 is an enlarged view indicating the pressure vibration due to the knocking shown in FIG. 1. As is apparent from FIG. 2, this vibration component due to the knocking includes a damping oscillation signal having frequencies higher than several kilo-Hertz.
As is obvious from FIGS. 1 and 2, during the generation of knocking, the knocking vibration is superposed on the ordinary cylinder internal pressure, and therefore gaseous vibration and standing waves are generated in the cylinder as a result of which unpleasant knocking sounds are caused, and at worst, high temperature is created locally in the cylinder which may damage the engine. However, the knocking phenomenon itself produces no bad influence on the engine. Even in the case where knocking is caused by advancing the ignition timing, the fuel consumption percentage of the vehicle can be improved by increasing the combustion efficiency of the engine. In view of the improvement of fuel consumption percentage, the acceptance of appropriate knocking is suitable to provide the most effective running condition of the engine.
Accordingly, in order to obtain the most suitable engine operating efficiency and to maintain the knocking noise level lower than a predetermined value, it is necessary to control the knocking strength according to various conditions.
Furthermore, the provision of a device capable of freely controlling the strength of knocking has been desired by the manufacturers in order to obtain data concerning the design of anti-knocking engines by strictly investigating the knocking phenomenon and to approach the best octane number of fuel.
Heretofore, the knocking phenomenon has been detected by the hearing sense of a vehicle operator or mechanic and accordingly the detection is very low in accuracy and unstable. As is clear from FIGS. 1 and 2, the cylinder internal pressure should be utilized for detecting the knocking strength. Nevertheless, a method of detecting the knocking strength based on the hearing sense has been employed. It should be noted that this method detects the noise which is caused as a result of the cylinder internal pressure variation. The noise reaches the ear through the cylinder block, the cylinder head or the like. Accordingly, the noise is damped or changed in quality, and is therefore considerably different from the actual cylinder internal pressure variation. Thus, the conventional knocking strength measuring method cannot detect the knocking strength with high accuracy. Accordingly, it has been impossible to perform ignition control with high accuracy to maintain the knocking strength in a desired allowable range which is determined from engine efficiency and noise.
At the manufacturer, a full acceleration test of the vehicle is carried out to evaluate the vehicle or fuel anti-knocking characteristic. In general, data is obtained for engine design by measuring the vehicle running octane numbers or fuel octane numbers according to a corrective border line method.
The test is carried out by the sensory judgement of the knocking phenomenon utilizing the hearing sense of a person and by the manual ignition timing control, and therefore the test is disadvantageous in that the experimental data lack reproducibility. In order to eliminate this difficulty, or to maintain the knocking strength precisely in the desired allowable range, the provision of a device capable of freely controlling the knocking strength with high accuracy has been desired.

Lesson: Introduction to Engine Knocking Control Devices

### Section 1: Theoretical Concepts
Engine knocking is a phenomenon that occurs in internal combustion engines when the load on the engine is too high and the ignition timing is too advanced. This causes abnormal hammering sounds, also known as knocking, which can damage the engine. Engine knocking control devices are designed to detect and control knocking in order to prevent damage to the engine.

### Section 2: Practical Examples
One example of an engine knocking control device is the knock sensor. The knock sensor is a device that is mounted on the engine and is designed to detect the vibrations caused by knocking. When the knock sensor detects knocking, it sends a signal to the engine control unit (ECU), which then adjusts the ignition timing and fuel injection to reduce the knocking strength.

Another example of an engine knocking control device is the variable valve timing system. This system adjusts the timing of the intake and exhaust valves in response to changes in engine load and speed. By adjusting the valve timing, the system can reduce the amount of knocking that occurs in the engine.

### Section 3: Real-World Scenarios
One real-world scenario where engine knocking control devices are used is in racing cars. In these cars, the engines are subjected to high loads and advanced ignition timings, which can cause knocking. By using engine knocking control devices, such as knock sensors and variable valve timing systems, racers can prevent damage to their engines and ensure that they perform at their best.

Conclusion:
Engine knocking control devices are essential for preventing damage to internal combustion engines. By understanding the theoretical concepts and practical examples of these devices, students can gain a deeper understanding of how they work and how they can be applied in real-world scenarios.

Effect of hypocapnia, hypercapnia, and blood pressure on NADH fluorescence, electrical activity, and blood flow in normal and partially ischemic monkey cortex.
Nicotinamide adenine dinucleotide fluorescence, cortical reflectance, cortical blood flow, and electroencephalograms were recorded from squirrel monkey brains before, during, and after focal transient cerebral ischemia produced by the temporary clipping of the middle cerebral artery. After release of the occluding clip, the monkeys were followed through an N2-breathing cycle and then to death from anoxia. The effects of controlled variations in arterial carbon dioxide tensions (PaCO2) and mean arterial blood pressures (MABP) were investigated in normal and in ischemic brain. In normal brain, with preserved autoregulation, NADH fluorescence was constant through a wide range in Paco2, MABP, and cortical blood flow. In ischemic brain, NADH levels increased, correlated closely with decreased cortical blood flow and EEG abnormalities, and became dependent on MABP. Artifacts in fluorescent measurements were reduced by: monochromators for excitation, emission, and reflected light; low intensity vertical excitation energy and high sensitivity recording instrumentation; and a small avascular (123 microns) field.

Lesson: Understanding the Effects of Hypocapnia, Hypercapnia, and Blood Pressure on NADH Fluorescence, Electrical Activity, and Blood Flow in Normal and Partially Ischemic Monkey Cortex

Introduction:
In this lesson, we will explore the effects of hypocapnia, hypercapnia, and blood pressure on NADH fluorescence, electrical activity, and blood flow in normal and partially ischemic monkey cortex. We will investigate how these factors affect the brain and how they can be measured and monitored.

Section 1: Understanding the Concepts

Topic 1: NADH Fluorescence
NADH is a coenzyme that plays a crucial role in cellular metabolism. It is involved in the transfer of electrons from one molecule to another. When NADH is oxidized back to its original form, it emits light at a specific wavelength, which can be measured as fluorescence. This fluorescence can be used as a marker for the presence of NADH and the activity of the enzymes involved in its metabolism.

Topic 2: Electrical Activity
Electrical activity refers to the movement of electrical charges within a system. In the context of the brain, electrical activity can be measured as electrical potential differences between different regions of the brain. These potential differences can be recorded as electroencephalograms (EEG), which provide information about the electrical activity of the brain.

Topic 3: Blood Flow
Blood flow refers to the movement of blood through the circulatory system. In the context of the brain, blood flow can be measured as the amount of blood passing through the brain at any given time. This information can be used to assess the health and functioning of the brain.

Section 2: Investigating the Effects

Topic 1: The Effects of Hypocapnia and Hypercapnia on NADH Fluorescence
Hypocapnia and hypercapnia refer to abnormal levels of carbon dioxide in the blood. Hypocapnia is a condition where there is too little carbon dioxide, while hypercapnia is a condition where there is too much carbon dioxide. Both of these conditions can affect the levels of NADH fluorescence in the brain. In general, hypocapnia leads to decreased NADH fluorescence, while hypercapnia leads to increased NADH fluorescence.

Topic 2: The Effects of Blood Pressure on NADH Fluorescence
Blood pressure refers to the force exerted by the blood against the walls of the arteries. Changes in blood pressure can affect the levels of NADH fluorescence in the brain. Generally, decreased blood pressure leads to decreased NADH fluorescence, while increased blood pressure leads to increased NADH fluorescence.

Section 3: Applying the Concepts

Topic 1: Applying the Concepts to Clinical Settings
The concepts discussed in this lesson can be applied in clinical settings to monitor and assess the health of the brain. For example, changes in NADH fluorescence can be used as a marker for brain activity and can be used to diagnose and monitor conditions such as stroke, traumatic brain injury, and neurodegenerative diseases.

Topic 2: Applying the Concepts to Research Settings
The concepts discussed in this lesson can also be applied in research settings to study the effects of different factors on brain function. For example, researchers can use the techniques discussed in this lesson to study the effects of different drugs or environmental factors on brain function.

Conclusion:
In conclusion, understanding the effects of hypocapnia, hypercapnia, and blood pressure on NADH fluorescence, electrical activity, and blood flow in normal and partially ischemic monkey cortex is essential for monitoring and assessing the health of the brain. By applying these concepts in both clinical and research settings, we can gain a deeper understanding of brain function and develop new treatments for brain-related conditions.

With the passage of time it is not uncommon for electrical boxes to become loose from the structures they are mounted to. Frequent attachments of plugs into an electrical outlet over time, for example, can cause the supporting outlet box to become unattached from the structure. The loosened electrical box is then a hazard, as it can cause loosening of wires within the box, electrical shorts, and potentially electrical shocks.
When an electrical box becomes loose, a prime consideration in replacing the box is minimizing damage to the surface surrounding the box. Electrical boxes for interior walls therefore must be capable of being easily installed into and secured to the existing wall without causing damage to the surrounding wall surface.
Electrical boxes have been developed specifically for the replacement of old electrical boxes, which are typically referred to as “old work” boxes. Prior art boxes of this type are described in U.S. Pat. No. 4,297,525 to Bowden, Jr., U.S. Pat. No. 4,120,473 to Suk, U.S. Pat. No. 5,603,424 to Bordwell et al., and U.S. Pat. No. 5,600,093 to Herth et al. In the above patent to Bowden, Jr., a box is shown which employs threaded mounting screws fastened into pawl arms. The pawl arms include tabs extending therefrom. After the box is inserted in an opening in a wall, tightening on the mounting screws urges the tabs linearly toward the box and eventually secures the box to the wall. Suk discloses a box that works in conjunction with a bracket to tighten against the wall. Bordwell et al. discloses a mounting assembly that includes clip-on securement members that are mountable to the outer sidewalls of an electrical box. Each securement member includes a bracket positioned on an external surface of the sidewall and a brace supported by the bracket. The brace is movable on the bracket so as to clamp the box to the mounting wall. Herth et al. discloses a modular interchangeable electrical work box. The work boxes have insert sheaths for fasteners for attaching the work box to a stud.
Although the patents to Bowden, Jr., Suk, and Bordwell et al. disclose electrical boxes for use in old work situations, they all rely on clamping type mechanisms that tighten onto the wall covering of the structure. Unfortunately, the wall covering is typically not a structurally strong portion of the wall. Sheet rock for example is used on interior walls, and is not a high strength material. So although the electrical boxes may clamp onto the wall material, the resulting electrical box is not very strongly attached.
The electrical box disclosed in Herth et al. improves the installation by providing fastener insert sheaths and fasteners. The fasteners are driven into the studs of the wall instead of into the wall covering. Although this is an improvement over the prior art boxes that employ clamping members, as a result of providing the fastener insert sheaths, the one-piece box disclosed by Herth et al. loses a large portion of the internal volume of the box. Therefore, although the box provides a better connection to the wall, the resulting volume within the box is small and provides inadequate space for completing wiring connections within the box.
An improved electrical box for retrofitting on finished walls or for use in new construction was disclosed in co-pending U.S. application Ser. No. 11/287,055, incorporated herein in its entirety and commonly owned by the assignee of the present invention, which included an internal mounting arrangement that was integral with a separate insert portion of the electrical box. By providing the internal mounting arrangement on a separate insert portion, the mounting arrangement is not formed as an integral portion of the box thereby taking up a large amount of otherwise usable volume in the electrical box.
The present invention expands upon the advantages of the electrical box of co-pending U.S. application Ser. No. 11/287,055 by providing a box that can be mounted horizontally and includes a mounting arrangement which is formed on a separate panel and then snap fit to the box to provide an internal mounting arrangement for the electrical box. By providing the mounting arrangement on a separate panel, more usable volume is provided within the box.

**Lesson:** Introduction to Crack Repair with Epoxy Resin

**Section 1: Theoretical Concepts**

Epoxy resin is a type of adhesive that is commonly used to repair cracks in various materials, including concrete, wood, and metal. It is a two-part system that consists of a resin and a hardener that are mixed together to create a strong and durable bond. In this lesson, we will explore the basic concepts of epoxy resin and its applications in crack repair.

**Section 2: Practical Examples**

To demonstrate the practical application of epoxy resin in crack repair, let's consider a scenario where a small crack has appeared on a concrete floor. To repair the crack, we will need to follow these steps:

1. Prepare the surface: Clean the area around the crack to remove any debris or dust that may interfere with the bonding process.

2. Mix the epoxy resin: Follow the manufacturer's instructions to mix the resin and hardener together in the correct proportions.

3. Apply the epoxy resin: Use a trowel or a similar tool to apply the epoxy resin into the crack, making sure to press it firmly into place.

4. Level the surface: Once the epoxy resin has been applied, use a straight edge or a level to ensure that the surface is level and that the crack is fully covered.

5. Allow the epoxy resin to cure: Follow the manufacturer's instructions for the curing time, which may vary depending on the specific product used.

**Section 3: Self-Debating Discussions**

Now that we have explored the theoretical concepts and practical examples of epoxy resin in crack repair, let's engage in a self-debating discussion to further our understanding of this topic.

**Question 1: What factors should be considered when selecting an epoxy resin for crack repair?**

- Strength and durability: The epoxy resin should be able to withstand the weight and pressure that it will be subjected to in its intended application.
- Chemical resistance: If the material being repaired will be exposed to chemicals or other corrosive substances, it is essential to choose an epoxy resin that is chemically resistant.
- Temperature range: The epoxy resin should be able to withstand the temperature range it will be subjected to, as extreme temperatures can affect its performance.

**Question 2: How can I ensure that the epoxy resin is applied evenly and correctly?**

- Use a level or a straight edge to check that the surface is level before the epoxy resin has fully cured.
- Apply the epoxy resin in thin layers, allowing each layer to cure completely before applying the next.
- Avoid applying too much pressure when applying the epoxy resin, as this can cause air bubbles to form and reduce the bonding strength.

**Glossary**

- Epoxy resin: A type of adhesive that is composed of a resin and a hardener that are mixed together to create a strong and durable bond.
- Adhesive: A substance that is used to join two surfaces together and is typically made from a mixture of a base polymer and a curing agent.
- Crack repair: The process of repairing small cracks or fissures in a material, such as concrete, wood, or metal.

**Conclusion**

In conclusion, epoxy resin is a versatile and powerful tool for crack repair in various materials. By understanding the theoretical concepts, following the practical examples, and engaging in self-debating discussions, we can develop a deep understanding of this topic and apply our skills to new problems.

[Protein-chip for autoantibodies profile detection].
We selected 12 antigens corresponding to commonly used autoantibodies in clinical practice to prepare antigen microarray. We chose NBT/BCIP color reaction as the end detection strategy to develop a new autoantibody protein chip detection system. Using this system, we optimized the best spotting solution, spotting concentration of the 12 antigens and the dilution of serum. We prepared a protein chip that could detect 12 autoantibodies simultaneously using the optimized antigen concentration. We established a new method to determine the cutoff of each autoantibodies by evaluation of 678 positive and 120 negative serum of clinical sample. We also evaluated the sensitivity and specificity of our new detection system. The optimal spotting solution was 0.1% TBST, the dilution of serum was 1:4 and the best spotting concentration of the 12 antigens were ANA 520 microg/mL, Ro-60/SSa 465 microg/mL, La/SSb 530 microg/mL, Jo-1 530 microg/mL, Scl-70 525 microg/mL, Sm 520 microg/mL, Ro-52/SSa 615 microg/mL, RF 340 microg/mL, CCP 465 microg/mL, ulRNP 410 microg/mL, CENP-B 490 microg/mL and dsDNA 580 microg/mL respectively. It had higher coincidence rate compared to current clinical used methods. We have developed a 12 antigens protein chip for the detection of autoantibodies based on the NBT/BCIP color reaction system. This system was fast, convenient, efficient, and cost-effective.

Lesson: Introduction to Autoantibodies Detection

Autoantibodies are antibodies that target the body's own proteins or tissues. They can be produced in response to various diseases, including autoimmune disorders. Detecting autoantibodies is crucial for diagnosing these conditions and monitoring their progression. In this lesson, we will learn about the basics of autoantibodies detection, including the types of autoantibodies, their functions, and the methods used to detect them.

Section 1: What are Autoantibodies?

Autoantibodies are antibodies that react with the body's own proteins or tissues. They are produced by the immune system in response to foreign substances, such as bacteria or viruses. However, in some cases, the immune system mistakenly produces autoantibodies that attack the body's own cells and tissues. This can lead to autoimmune disorders, such as lupus, rheumatoid arthritis, and multiple sclerosis.

Section 2: Types of Autoantibodies

There are several types of autoantibodies, each targeting specific proteins or tissues. Some common examples include:

- Anti-nuclear antibodies (ANA): These antibodies target proteins within the nucleus of cells.
- Rheumatoid factor (RF): These antibodies are found in people with rheumatoid arthritis and may contribute to joint damage.
- Cyclic citrullinated peptide (CCP) antibodies: These antibodies are associated with rheumatoid arthritis and may predict the development of the disease.
- Anti-dsDNA antibodies: These antibodies target DNA and are associated with lupus.

Section 3: Functions of Autoantibodies

Autoantibodies play a crucial role in the immune system's response to foreign substances. However, when they target the body's own proteins or tissues, they can cause damage and lead to autoimmune disorders.

Section 4: Methods of Autoantibodies Detection

There are several methods for detecting autoantibodies, including:

- Enzyme-linked immunosorbent assay (ELISA): This method uses antigens to detect the presence of autoantibodies in a sample.
- Immunofluorescence: This method uses fluorescent antibodies to detect the presence of autoantibodies in tissue samples.
- Immunohistochemistry: This method uses antibodies to detect the presence of autoantibodies in histological samples.

Section 5: Conclusion

In this lesson, we learned about autoantibodies, their types, functions, and methods of detection. Understanding autoantibodies is essential for diagnosing and treating autoimmune disorders. By detecting autoantibodies, doctors can monitor the progression of these conditions and adjust treatment plans accordingly.

WET PROCESSINGThe Goldlands Trommel Scrubbers are engineered to wash and separate its process volumes efficiently and expeditiously, using interior spirals to lift and direct the material froward. The bank ore enters the grizzly/hopper wherein a high pressure water sprays hits the process material, slurrying it into the slowly rotating scruber ( 8 RPM). As it churns its way forward, lifting and falling via the spiralling flights, the saturated volume enters a section of high density boom chains which thrash the volume, breaking any conglomerated clays and minerals. Upon exit, the washed and separated ore is now ready for precious metals and gemstone concentration.

DRY PROCESSINGWhere water is scarce, the material to be processed can be fed, dry. In this Goldlands' Scrubbing Unit, the boom chain compartment length is increased and the volume is hit continuously to adequately break apart clumped and consolidated volumes.

GOLDLANDS Trommel Scrubbers

TRANSPORTATION OF TROMMEL MINERAL SCRUBBERSThe Goldland Trommel Scrubbers are mounted on highway trailers for ease in shipping both to and on the mining claim or concession. The units can also be skid mounted if the unit is to be stationary on the mining property.

TROMMEL AND SCRUBBER SIZESGoldlands manufactures various trommel sizes and specifications to accommodated the custom production goals of the mining operation. Trommel 30, 50 and 100 process the accommodating tonnage per hour, while Trommel Plus scrubs from 100 to 300 Tons per hour.

Introduction:
Mineral processing is the first step in extracting valuable minerals from the earth's crust. It involves the use of various techniques to separate and concentrate minerals from the ore. There are two main methods of mineral processing: wet and dry processing.

Wet Processing:
Wet processing involves the use of water to wash and separate minerals from the ore. This method is commonly used when the ore is sticky or contains clay or other materials that are difficult to separate using dry processing methods.

Dry Processing:
Dry processing involves the use of air or mechanical means to separate minerals from the ore. This method is typically used when the ore is dry and free of moisture.

Goldlands Trommel Scrubbers:
The Goldlands Trommel Scrubbers are a type of wet processing equipment used in the mining industry to wash and separate minerals efficiently. They are designed with interior spirals that lift and direct the material forward, allowing for efficient separation of minerals.

Components of Goldlands Trommel Scrubbers:
- Grizzly/Hopper: This is where the ore enters the scrubber.
- High-pressure water sprays: These sprays hit the process material, slurrying it into the slowly rotating scrubber.
- Spiraling flights: These flights lift and fall as the ore moves forward, separating minerals.
- Boom chain compartment: This section is increased in length to adequately break apart clumped and consolidated volumes.

Transportation of Trommel Mineral Scrubbers:
The Goldlands Trommel Scrubbers are designed to be easily transported to and from mining claims or concessions. They can be mounted on highway trailers or skid-mounted depending on the location and need.

Conclusion:

Meeresstille und glückliche Fahrt (Beethoven)

Meeresstille und Glückliche Fahrt, Op. 112 ("Calm Sea and Prosperous Voyage") is a cantata for chorus and orchestra composed by Ludwig van Beethoven. It is based on a pair of poems by Johann Wolfgang von Goethe. They met in 1812; Beethoven admired him and the work is dedicated to Goethe. It was first performed in Vienna in December of 1815, and first published in 1822. The piece is in a single movement, with a typical performance taking between 7 and 8 minutes. The single movement is in two sections: (1) "Meeresstille" – Sostenuto – D major; and (2) "Glückliche Fahrt" – Allegro vivace – D major.

The cantata evokes the imagery of the pair of poems which later inspired the concert overture of the same name by Mendelssohn. The poems' titles are not synonymous: in the days before steam, a totally calm sea was cause for alarm; it is only when the wind at last rises that the ship can continue on its journey. The first section depicts a ship becalmed, the second its success in resuming its voyage.

Text

Instrumentation
The cantata is scored for the following orchestra.

Woodwinds: 2 flutes, 2 oboes, 2 clarinets in A, 2 bassoons
Brass: 4 horns in D, 2 trumpets in D
Percussion: timpani
Strings: violins I & II, violas, cellos, double basses
SATB choir

The present invention generally relates to semiconductor devices, and more particularly to a semiconductor device having a STI structure and fabrication process thereof.
With progress in the art of device miniaturization, it is now possible to fabricate ultrafine/ultra high-speed semiconductor devices having a gate length of less than 100 nm. In such ultrafine/ultra high-speed semiconductor devices, an STI (shallow trench isolation) structure is used commonly as a device isolation structure.
With such ultrafine/ultrahigh speed transistors, it should be noted that the area of the channel region right underneath the gate electrode is far smaller as compared with the case of conventional semiconductor devices, and thus, mobility of electrons or holes traveling through the channel region is influenced heavily by the stress applied to the channel region. Thus, various attempts have been made so far for improving the operational speed of the semiconductor device by optimizing the stress applied to the channel region thereof.

Lesson Title: Understanding Semiconductor Devices and their Fabrication

**Introduction:**
Semiconductor devices are electronic components that use semiconductor materials, such as silicon, to control the flow of electricity. These devices are used in a wide range of applications, including computers, smartphones, and televisions. In this lesson, we will learn about the basic structure of semiconductor devices and the fabrication process used to create them.

**Section 1: Understanding Semiconductor Devices**

**Topic 1: Types of Semiconductor Devices**
There are two main types of semiconductor devices: diodes and transistors. Diodes allow current to flow in one direction, while transistors can amplify or switch electronic signals.

**Topic 2: The P-N Junction**
The p-n junction is the basic building block of all semiconductor devices. It consists of a layer of p-type material (with extra electrons) separated from an n-type layer (with fewer electrons) by a thin insulating barrier called the depletion region. This junction allows for the control of electric current flow.

**Topic 3: The Fabry-Perot Interferometer**
The Fabry-Perot interferometer is a device that uses multiple p-n junctions to split and recombine light waves. It is used in various applications, such as optical communications and spectroscopy.

**Section 2: Fabrication Process of Semiconductor Devices**

**Topic 1: Epitaxial Growth**
Epitaxial growth is the process of depositing a thin layer of semiconductor material onto a substrate. This technique is used to create layers of different semiconductor materials, such as silicon and gallium arsenide, which have different properties.

**Topic 2: Doping**
Doping is the process of adding impurities to a semiconductor material to change its electrical properties. There are two types of doping: n-type and p-type. N-type doping adds extra electrons to the material, while p-type doping removes electrons.

**Topic 3: Ion Implantation**
Ion implantation is a process used to introduce dopants into a semiconductor material. Ions are accelerated to high speeds and then directed into the material, where they collide with atoms and create new dopant atoms.

**Section 3: Applications of Semiconductor Devices**

**Topic 1: Integrated Circuits**

Immigration advocates were trying to balance empathy with outrage the day after President Donald Trump said he has directed the Department of Homeland Security to create an office for victims of crimes committed by immigrants.

Trump said he has ordered the creation of the Victims of Immigration Crime Engagement, or VOICE to provide "a voice to those who have been ignored by our media, and silenced by special interests." He underscored during his speech his demand by spotlighting four victims of immigrants who committed crimes.

But advocates said Wednesday they saw the plan as political baiting and a continuation of the theme that Trump has seized on since the start of his campaign, with his statements about rapists and criminals coming from Mexico.

“People of course want to be respectful of someone who has lost a family member, who is a victim of crime,” said Angela Kelley, senior strategic adviser for immigration at the Open Society Policy Center.

“The concern is there seems to be a repeated pattern of the Trump administration to link immigrants with criminality, using the emotions that come along with family members who have lost a loved one,” Kelley said. “It’s bait we don’t want to take.”

While Trump's speech was largely praised as a departure from his rhetoric of the campaign and a softening of his tone, immigration advocates said they saw little departure from his hardline approach to immigration.

Trump included the order for the office in one of his immigration executive orders and had made crimes by immigrants not legally in the U.S. a campaign issue.

But his mention of it in a nationally televised speech got instant reaction. Although his supporters applauded, it also drew audible groans and boos from part of the congressional audience and some swift blowback on social media.

Shame on you, #POTUS. Exploiting the pain of ppl who've lot loved ones & using their grief to instill fear against #immigrants #JointSession — Marielena Hincapié (@MarielenaNILC) March 1, 2017

The idea was dismissed by Sen. Chuck Schumer, the Senate minority leader, Wednesday morning.

"I think that office is ridiculous," Schumer, D-N.Y., said on CBS This Morning. "Obviously we want to go after criminals. The overwhelming majority of immigrants are law abiding...So to put an office like this out there shows how anti-immigrant this president is."

Maria Teresa Kumar, president and CEO of Voto Latino, said Trump’s speech was “the same dog whistle politics that got him elected.”

“He invited guests whose loved ones were victims of terrible tragedies, and we all share their pain. But to use that pain to create more fear by insinuating that all immigrants are criminals and murderers is un-American and dangerous,” Kumar said.

“Creating a DHS hotline, Victims of Immigrant Crime Engagement, will only lead to further racial tension and profiling and will not make our country any safer,” she said.

Trump’s idea for such an office came from Maria Espinoza, director of the Remembrance Project.

Espinoza, who said she is not a victim of a crime by an immigrant, has been trying with her husband since 2012 to get offices and services dedicated to such crime victims. She wrote letters to every state governor and to four of the GOP candidates, including Trump. Only he responded, she said. She did not send a letter to Hillary Clinton.

What the group seeks sounds similar to what other crime victims have pressed for over the years: financial assistance with burial costs, medical and trauma services, compensation for lost wages and help navigating the criminal justice system, as well as legal assistance.

But Espinoza said the needs of victims she advocates for “cannot be handled the same” as those of other crime victims, because the perpetrators are illegally in the U.S. If they are here illegally they should be removed from the country” after serving their sentences.

DHS has programs in place designed to remove immigrants from the country as soon as their sentence has been served.

Espinoza is an opponent of so-called sanctuary cities that limit the extent local law enforcement will probe a person’s immigration status or restrict interaction with ICE with someone arrested for a minor crime. She also praised Trump's plan for a border wall.

“Right now we have a very open border,” Espinoza said.

There has been criticism of her group’s links to anti-immigrant groups and individuals, as reported in a 2015 article by Buzzfeed.

On its website, Espinoza's group calls for a fee on remittances - the money immigrants send to families in their home countries - to pay for the victims' assistance.

Danny Vargas, a Republican communications consultant, praised Trump's speech overall, saying he hoped it was a turning of a corner. But he was skeptical of the plan to create VOICE. He called it "red meat" Trump threw out to appease more zealous portions of the base.

The Office for Victims of Crime already exists in the Department of Justice. It was created by Ronald Reagan to focus on all types of crimes and all types of victims.

"It's complete and utter duplication and there's no need," Mai Fernandez, executive director of the National Center for Victims of Crime, a non-profit group, said of Trump's VOICE plan.

“I’m not sure what this office would do or what services it would offer different than what is available at DOJ,” Fernandez said.

The department provides funding and technical assistance to organizations and determines how those can be used to best serve all victims of crime. It has conducted research and identified underserved communities that need special attention because they can’t access the resources that are out there, Fernandez said.

Studies show that criminal activity by immigrants is lower than by non-immigrants.

A program within DOJ for victims that are the focus of Trump's plan could be started if there is need, but Fernandez said data should be collected first to show how large the population is and what the victims' special needs are.

“I’m not sure why President Trump is creating a new office in a different department,” she said. “I think that’s going to create more bureaucracy.”

She acknowledged that getting compensation or services might be difficult, but she said that is true across the board for crime victims.

“There are lots of people looking at how to make compensation more accessible,” she said. But a new office with its own source of funding “would be wasted resources that are needed to get services to victims.”

1. Field of the Invention
The invention relates to an image color adjusting technique.
2. Description of the Related Art
When images are taken using image-generating devices such as digital still cameras and video cameras, the entire image is processed by what is referred to as color balancing. The color balancing technique is disclosed, for example, in JP3469305B, JP11-205806A, JP10-210494A, and JP2-128591A.
Color balancing is done to reduce colorcast in images in order to allow the photographed subject to be accurately reproduced in the original white color. Such color balancing is often done using white areas which are nearly achromatic, and is thus also referred to as white balancing.
However, the colors in the image can turn into various colors according to the colors of the photographed subject, and can also turn into various other colors (color cast) depending on the color of the light source. Thus, in color balancing, color deviation is evaluated using various colored components which are nearly achromatic in order to reduce various types of colorcast. However, conventional color balancing has not taken into consideration the distribution of colors which are nearly achromatic in the processed image.
This problem is not limited to color balancing processes, but also pertains to processes for adjusting image colors.
Another problem concerning color balancing is that it is sometimes not possible to accurately reproduce the original colors no matter how much RGB color components is adjusted in order to compensate for light source differences.

Lesson: Image Color Adjusting Technique

Introduction:
In this lesson, we will learn about an image color adjusting technique that helps in accurately reproducing the photographed subject in its original white color. We will understand the related art, the need for color balancing, and the challenges associated with it.

Core Value:
The core value of this lesson is to understand the importance of color balancing in image processing and the challenges associated with it.

Section 1: Overview of the Image Color Adjusting Technique

Topic 1: Definition of the Technique
Color balancing is the process of adjusting the colors in an image to make it appear more natural and accurate. It is also known as white balancing because it involves adjusting the white parts of the image to appear neutral.

Topic 2: Need for Color Balancing
When we take pictures using digital cameras or video cameras, the entire image is processed by what is known as color balancing. This is necessary because the colors in the image can vary depending on the colors of the photographed subject and the light source. Color balancing helps to reduce colorcast and ensure that the image appears natural and accurate.

Section 2: Conventional Color Balancing Techniques

Topic 1: Conventional Color Balancing Techniques
Conventional color balancing techniques involve evaluating color deviation using various colored components which are nearly achromatic. This is done to reduce various types of colorcast. However, these techniques do not take into consideration the distribution of colors which are nearly achromatic.

Topic 2: Challenges with Conventional Color Balancing Techniques
The challenges with conventional color balancing techniques include the fact that they do not consider the distribution of colors which are nearly achromatic. This means that the colors in the image may not appear natural and accurate. Additionally, these techniques may not work well with images that have a lot of color variation.

Section 3: Advanced Color Balancing Technique

Topic 1: Advanced Color Balancing Technique
An advanced color balancing technique involves considering the distribution of colors which are nearly achromatic. This helps to ensure that the colors in the image appear more natural and accurate.

Topic 2: How the Technique Works
The advanced color balancing technique involves analyzing the distribution of colors in the image and adjusting them accordingly. This is done by comparing the colors in the image to a reference color space, such as the CIE 1931 color space. The technique then adjusts the colors in the image to match the reference color space.

Section 4: Practical Examples

Topic 1: Example 1
Suppose we have an image of a person wearing a red shirt against a green background. Conventional color balancing techniques may not be able to accurately adjust the colors in the image because the colors are not nearly achromatic. However, the advanced color balancing technique can analyze the distribution of colors in the image and adjust them accordingly, resulting in a more natural and accurate image.

Topic 2: Example 2
Suppose we have an image of a landscape with a variety of colors, including green trees, blue sky, and brown rocks. Conventional color balancing techniques may not be able to accurately adjust the colors in the image because there is a lot of color variation. However, the advanced color balancing technique can analyze the distribution of colors in the image and adjust them accordingly, resulting in a more natural and accurate image.

Glossary:
- Color balancing: The process of adjusting the colors in an image to make it appear more natural and accurate.
- White balancing: A type of color balancing that involves adjusting the white parts of the image to appear neutral.
- Colorcast: A color shift in an image due to the color of the light source.
- Achromatic: A color that appears neutral and does not have any hue.
- Color deviation: The difference between the colors in an image and the colors in a reference color space.
- CIE 1931 color space: A standard color space used for comparing colors.

Conclusion:
In this lesson, we learned about an image color adjusting technique that involves considering the distribution of colors which are nearly achromatic. This advanced color balancing technique helps to ensure that the colors in the image appear more natural and accurate. By understanding the principles behind this technique, we can apply it to various scenarios and improve the quality of our images.
