Abstract: PURPOSE:To enhance reliability of element of a semiconductor device by a method whrein a polycrystalline silicon thin film is converted into an oxide film by thermal oxidation. CONSTITUTION:After pattern formation of the polycrystalline silicon film 3 is performed, a still thinner (100-1000Angstrom ) polycrystalline silicon film 8 is made to grow, and an oxide film 4 is made to grow thereon by vapor growth. By this constitution,  even when photo etching for diffusion is performed after then, because the polycrystalline silicon film 3 is not violated by an etching liquid and act as an etching  stopper, the end part of the polycrystalline film is not violated perfectly. The second polycrystalline silicon film 8 is converted into an oxide film 9 by thermal oxidation,  and moreover the second field region is made to grow by CVD. After then Al is  evaporated, and photoetching of Al is performed to complete wiring.

Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a crew restricting and protecting device for vehicles which can quickly and accurately control a motor by using an inexpensive MPU. SOLUTION: Terminals P1 and P2 of a crew restricting and protecting device for vehicle are input terminals for pulse width modulation(PWM) signals outputted from an MPU14 and PWM signals of, for example, 20 kHz are inputted to the terminals P1 and P2. Each of the IF1-IF4 of the device is constituted in a low-pass filter composed of, for example, a resistor r2, another resistor r3 having a resistance value which is smaller than that of the resistor r2, and a capacitor c3 and the cut-off frequency of each filter is set at, for example, 20 Hz.  As a result, the effects to the PWM signals outputted to the MPU 14 from a current detecting circuit C1 and a voltage measuring circuit C2 are reduced to -60dB and the current which is to be detected by means of a current detecting circuit C1 and the terminal voltage to be measured by means of the voltage measuring circuit C2 are hardly affected by the PWM signals.

Filed: 1980-09-10
Abstract: PURPOSE: To perform etching scarcely causing side etching at a high speed by mixing an electric discharge gas contg. fluorine with gaseous hydrogen, and forming a mirror magnetic field forming uniform plasma in an electric discharge space.  
     CONSTITUTION: SF 6  and H 2  are introduced from cylinders 16, 17 via a lead-in port 15 into an electric discharge space 5. The introduced discharge gases are turned to plasma by the synergistic effect to a mirror magnetic field formed in the discharge space by a magnetic field generating coil 7 and a permanent magnet 8 and a microwave electric field formed in the discharge space 5 by the microwaves from a microwave generator 3 propagated in a waveguide 4. The active ions in the generated  plasma move downward of the space 5 along the mirror magnetic field and fall onto  the sample 12 on a rotary table 10, thereby etching the surface of the sample 12.  The occurrence of side etching is prevented by mixing the discharge gas contg.  fluorine with gaseous H 2  to form HF and decrease fluorine radicals, and further the  decrease in the rate of etching is prevented by mixing the same with the gaseous O 2   from a cylinder 18.

Abstract: PURPOSE:To prevent the occurrence of raster ringing, by installing an electrostat ic shield between a horizontal coil and a vertical coil, and installing an element which cuts off a signal of the component of a horizontal deflecting signal to be fed to the horizontal coil, in the vertical coil in series. CONSTITUTION:An electrostatic shield 3 is installed between a vertical coil 2 and a horizontal coil 1, while an element 4 is installed in this vertical coil 2 in series. Crosstalk of a signal from the horizontal coil 1 to the vertical coil 2 is reduced by the electrostatic shield 3, while an oscillating current induced to the vertical coil 2 is cut off by the element 4, preventing this oscillating current from flowing into the vertical coil 2, whereby raster ringing attributable to this oscillating current is very favorably and sufficiently reduced. In this connection, an electric conductor constituting the electrostatic shield 3 can be constituted in a so-called separator for insulating both vertical and horizontal coils. With this constitution, the oscillating current is prevented from occurring, and raster ringing attributable to the vertcal coil is very favorably and sufficient ly reducible.

Title: Controller for solenoid clutch for automobile

IPC: B60W10/04
Filed: 1985-06-10
Abstract: PURPOSE:To always enable the delivering of starting performance as desired preventing effect of aging of a solenoid clutch, by controlling the excitation current of the clutch so that the transmission torque detected of a power transmission shaft can match the revolution of the engine. CONSTITUTION:A controller 12 calculates the desired transmission torque of a clutch output shaft corresponding to the rotational speed of the engine detected with an engine rotational speed detector 7 to be compared with the transmission torque value of the clutch output shaft detected with a torque detector 8. When the torque value detected is smaller than the calculated value, the supply current to a clutch 3 is controlled so that the linking torque of the clutch will be increased by augumenting the excitation current to be supplied to a solenoid clutch 3 when the torque value detected is larger than that calculated while it will be decreased by reducing the excitation current of the clutch 3. This can always control the transmission torque of the output shaft to that to match the engine rotation speed, thereby assuring a better starting characteristic free from effect of aging on the clutch 3.
