Title: Manufacture of schottky gate type field effect transistor
Inventor: UCHITOMI NAOTAKA
IPC: H01L21/265
Filed: 1986-08-19
Abstract: PURPOSE:To suppress the increase in substrate current flowing directly beneath a channel region even if the length of a gate is made sufficiently short, by forming a Schottky gate on the surface of an active layer in a recess part, which is formed in a gate forming region beforehand, implanting high concentration ions with a gate electrode as a mask, and forming source and drain regions. CONSTITUTION:The surface of a semi-insulating GaAs substrate 1 is etched, and a recess part 2 is formed at a part including a gate forming region. A gate electrode 5 is formed. Then, an Si3N4 film 6 is selectively formed on the side wall of the gate electrode 5. The selective formation of the Si3N4 film 6 is performed by the following way : the Si3N4 film is deposited on the entire surface by a CVD method, thereafter etchback is performed by reactive ion etching, and the film is made to remain on the side wall of the gate electrode 5. Thereafter, Si ions are implanted second time with the gate electrode 5 and the Si3N4 film 6 as masks. Thus high-concentration Si-ions implanted units 81' and 82' are formed in source and drain regions.

Title: Method for detecting presence or absence of indication of light-transmitting article
Inventor: SUGANO HISAYOSHI
IPC: G01V8/12
Filed: 1989-07-26
Abstract: PURPOSE:To enable detection of presence or absence of an indication to be applied to the main body of a light-transmitting article by detecting whether the main body of the light-transmitting article passes or not and whether an indication having a non-transparent area, which is to be applied to a semitransparent article, is present or not. CONSTITUTION:When a light-transmitting or semitransparent article 4 passes through a sensor 1, a part of the quantity of light from a projector la is intercepted, a gain of a photosensor 1b lowers to a reference level V0 for detection of light or below, and no light detection signal is generated from the sensor 1. This output constitutes a detection signal (al) through the intermediary of an NOT circuit. As to a sensor 2, a photosensor 2b outputs a light detection signal when no non-transparent indication 5 passes between a projector 2a and the photosensor 2b. When the indication 5 passes there-through,the light is intercepted and a light detection output signal is not outputted. This signal constitutes a detection signal a2 through the intermediary of the NOT circuit. When both of the signal (a1) of the article 4 by the sensor 1 and the signal a2 of the indication 5 by the sensor 2 are outputted, an abnormality detection signal is not emitted, and when the detection signal is delivered from either one of them, the abnormality signal is emitted.

Inventor: ISHIZEKI SEIICHI
IPC: B60T8/172
Filed: 1986-08-19
Abstract: PURPOSE:To prevent the occurrence of yawing moment due to insufficient braking force or the like by not releasing braking hydraulic pressure at the releasing point of said pressure, and supplying said pressure stepwise to a braking device for its pressurization when both a cutting off and a releasing point of the braking hydraulic pressure occur within a prescribed high speed range. CONSTITUTION:In braking a vehicle, when the lower of outputs fed from wheel speed sensors 3b, 6b on, for instance, A cross piping system is selected (low- selected) in a control circuit 8, and the rate of decrease in a selected wheel speed signal exceeds its setting value, an actuator 7a is energized to cut off the supply of braking hydraulic pressure to the other pipe line for keeping said pressure constant. In this case, when both a cutting off and a releasing point of the braking hydraulic pressure occur within a prescribed high speed range, the braking hydraulic pressure is not released at the releasing point of the said pressure, and is supplied stepwise to a braking device. When the wheel speed signal on a not low-selected side becomes below the prescribed high speed range or said signal on a low-selected side comes in a prescribed low speed range, the braking hydraulic pressure is released.

Abstract: PROBLEM TO BE SOLVED: To enhance the reliability by providing input terminals, a semiconductor switching element, a rectifier element, a current detection resistor and an integration circuit thereby controlling a DC motor accurately at all times. SOLUTION: When a positive voltage is inputted to input terminals 45, 46, a field effect transistor 22 is turned on upon provision of an input voltage to the gate of field effect transistor 22.

Abstract: PURPOSE:To execute a plurality of simultaneous tests for each block in the integrated circuit at high speed by regarding the content of an ROM memorizing a program as a mere data, arithmetically and logically operating the data by an ALU and investigating the result. CONSTITUTION:In a test executing addition to all words in a device such as an ROM 2, one word using the value of a program counter PC3 as an address is read from the ROM2, and set to an instruction register IR4. Addition is executed between the register and an accumulator register ACC5. The result of addition is set to the register ACC5 by the next clock. The operation is repeated to all words in the ROM2. When the test is executed to all words, the test is completed because the value of a counter register 11 reaches zero. The value of the register ACC5 must reach the sum of all words of the ROM2 at that time. Consequently, the value of the register ACC5 is investigated. The contents of all words of the ROM2 can be inspected by the test, and the function of the addition of the arithmetic logic operation unit ALU6 can also be inspected. Functions as registers of the instruction register IR4 and the register ACC5 can also be inspected from the result, and the function of the counting of the program counter PC3 can also be inspected.
