Title: Manufacture of semiconductor device
Inventor: ABE HIDEJI
IPC: H01L21/8242
Filed: 1985-03-07
Abstract: PURPOSE:To improve the withstand voltage between the first polysilicon and second polysilicon and the yield by a method wherein a silicon oxide film is removed by exposing the silicon nitride produced on the interface between the silicon substrate and the silicon oxide film, thereby dispensing with sacrifice oxidation. CONSTITUTION:After a silicon oxide film 3 is formed on a silicon substrate 1, a silicon nitride film 4 is formed, and the first polysilicon 5 is selectively wet-oxidized as a oxide mask to form a silicon oxide film 6 on the upper surface of it. At this time, a part of the silicon oxide film 4 is partially oxidized so that an oxidized part 13 is produced and then, reacting with the silicon substrate 1 through a thin silicon oxide film 3 to produce a silicon nitride 8. Then, etching is performed to remove this. When a silicon oxide film 6 on the silicon nitride film 4 is removed, the edge section 9 of the first polysilicon 5 is protected by the silicon nitride film 4, with the result that a favorably shaped edge section is obtained after the silicon nitride film 4 is removed.

Title: Brushless dc motor
Inventor: YAMAUCHI HIROYUKI
IPC: H02P6/14
Filed: 1979-04-11
Abstract: PURPOSE:To facilitate the adjustment of the switching timing of the conduction of a coil by providing a counter wherein the conduction angle of the driving currents to be supplied to the stator coils are set so that said angle becomes optimum at the point of generated torque. CONSTITUTION:A flip-flop 4 is set by the rise-up of the position sensing signal from a Hall element 2. Said signal and the pulse signal from a frequency generator 3 are given to an AND gate 6, and counting is performed by a preset counter 7.  Then, a counter 11, whose conduction angle is determined by the output of the  counter 7, is operated, and the timing of starting the counting of the counter 7 is  determined by the output of the counter 11, thereby driving currents are sequentially supplied to stator coils 1a-1c. Since the conduction angle is determined to  become optimum by the counter 7, timing adjustment can be readily performed  without adjusting the position-sensing element.

Title: Device for measuring deflection
Inventor: JIYON EI BERU
IPC: G01B11/00
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To relaize deflection measurement with high resolution and high accuracy by sending laser light having two frequencies to a deflection sensing head from a light source through an optical fiber and adopting the optical heterodyne interferometry which is symmetrical complementarily. SOLUTION: A light beam passing through a fiber F is collimated by a lens L, and it is sent to the following routes. A polarization beam splitter P2 divides the light into two frequency elements through polarization. A mirror reflects the beam toward a non-polarization beam splitter N, and the beam arrives at a return reflector R1 or R2. Polarization analysers A1 and A2 before optical detectors D1 and D2 are arranged orthogonally in the same manner as typical heterodyne interferometer, and they send about half of respective polarization element of incident beam. The beam has two frequency elements, and since they are in the same polarization condition, they are subject to optical interference.  The inter-ferometer processes electrically two interference phases which are changed due to deflection, and the quantity to be processed thereby is the same as that of heterodyne interferometer excluding their phase difference.

Title: Engine controller
Inventor: NAKAGAWA SHINJI
IPC: F02D41/16
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To absorb an air-fuel ratio correction relative error between λa and λb, and solve delay of feed back control by changing idle feed back, step by step, by a relative error of the air-furl ratio correction the moment the air-fuel ratio is changed from λa to λb at the time of idle control. SOLUTION: In a control unit 17 for inputting output signals such as an air flow sensor 3, an O2 sensor 13, a water temperature sensor 14, a rotating speed sensor 15, and an acceleration sensor 16, e=Ea-Eb shows a relative error of an air fuel ratio correction when feed back operating rates are set as Ea and Eb in target air-fuel ratios λa and λb in a regular condition on idling operation. The feed back operating rates Ea, Eb are memorized, in the case where a demand for switching the target air-fuel ratio λa into the target air-fuel ratio λb is generated, a value obtained by subtracting only the relative error (e) from the feed back operating rate is set as a new feed back operating rate simultaneously with switching. It is thus possible to prevent responsiveness delay of the feed back, and rotation fluctuation is suppressed.

Abstract: PURPOSE:To prevent malfunction by providing a presser part and a pressure reception part to a rotating body which transmits the turning force of a motor, moving the pressure reception part onto the rotational track of the presser part with the tensile force of a tape, and holding the pressure reception part off the track up to right after the presser part passes by the pressure reception part. CONSTITUTION:When a rewinding operation member is pressed in and a magnetic head 3 detects the position of a desired tape, a signal is generated and a current flows through a coil 57 to move a lock plate 47, returning the rewinding operation member 13. At this time, the tensile force increases abnormally, a tape contact piece 66 is pressed down, and the rotational extent is limited by a slide piece 63A. When a gear 29 rotates, an operating member 63 disengages from a control member 67 and rotates counterclockwise. When the gear 29 further rotates, a projection 61 engages a projection part 62 and the operation member 63 further rotates counterclockwise; and a lock piece 63B engages a lock piece 46C to move the lock piece 46 to right, and a lock piece 46A disengages from a projection piece 11A and stops automatically. Consequently, reproduction operation is started continuously after program searching operation.

Title: Position controller
Inventor: NAITOU AKIRA
IPC: G05B19/402
Filed: 1984-03-09
Abstract: PURPOSE:To ensure the automatic positioning at a high speed and with high accuracy with a position controller by catching an object to be detected through an image pickup device and setting the center position of said object so as to coincide with a prescribed position of the image pickup device. CONSTITUTION:A mark 11 is picked up by a TV camera 12 and this image pickup signal is sent to a position controller 13. The controller 13 binary codes the image pickup signal. The data on this binary coded signal is decomposed into an orthogonal coordinate system by means of horizontal and vertical synchronizing signals which are sent to a TV camera. Thus position coordinates are obtained for corner parts P1-P4 of the mark 11. Based on these position coordinates, the coordinates are calculated for the center C of the mark 11. Then the difference is calculated between the coordinates of the center C and a standard center D. The result of said calculation is decomposed into X and Y directions and sent to a positioning mechanism 10 in the form of the variance data. In such a way the accurate positioning with a position controller is ensured.
