Patent JP-S62126-A (JP)
Title: Photoelectric switch
Inventor: FUKUDA MASAHIKO
IPC: H03K17/78
Filed: 1985-06-26
Abstract: PURPOSE:To allow the titled switch to be hardly affected by external disturbance by inhibiting the inversion of an output signal of a presettable counter so long as a photodetecting element does not receive prescribed numbers of pulse light continuously. CONSTITUTION:A pulse oscillator 1, a light projecting element 2, a projecting element drive circuit 3, a photodetecting element 4, an amplifier 5, a latch circuit 7 and a detection output circuit 8 are components in common to a conventional circuit. A waveform shaping circuit 6 applies waveform shaping an amplified reception signal (c) by a method different from the conventional method. The presettable counter 9 receives the output signals k-m of a counter control circuit 10, outputs detection signals i, j representing whether or not the photoelectric switch receives a pulse light and gives the result to the detection output circuit 8. The counter control circuit 10 presets or resets the output signals i, j of the counter 9 based on the output signals e, j of the latch circuit 7 and the output signals i, j of the double counter 9 synchronously with a delay signal (b) of the oscillation pulse (a) of the latch circuit 7.

Title: Detector for tape drive variation
Inventor: MATSUI TSUTOMU
IPC: G11B15/18
Filed: 1983-07-31
Abstract: PURPOSE:To detect the drive variation of a tape with high accuracy by providing a mirror at a part of a magnetic head, irradiating a light beam having vibrations in the width direction of the tape to the mirror and detecting the light reflected from the mirror. CONSTITUTION:A mirror 14 is set at the front part of a head 13 of a cassette tape 11 and at the same time at a place not to be opposite to a pat 15. A mirror 32 is set at a part opposite to the mirror 14 to reflect the external light to the mirror 14 via the driving path of a tape 12. The beam generated from a semiconductor laser light source 19 is vibrated in the width direction of the tape 12 via a wobbling mirror 24 and then supplied to the mirror 32. A light sensor 27 detects the reflected light sent from the mirror 14 as a return light beam and converts it into electrical signals. An oscillator 26 produces a control signal which drives the mirror 24 as well as a rectangular wave signal which is synchronous with said control signal. The output of a monostable multivibrator circuit 29 which is triggered by the output of the sensor 27 is compared with the output of the oscillator 26 by a phase comparator 30. Thus the tape drive variation is detected with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To maintain stable performance over a long period by dissolving a sensitizing coloring matter adhered to a photosemiconductor electrode to an electrolytic solution which is arranged between a coloring matter sensitizing type photosemiconductor electrode and a counter electrode. SOLUTION: In a wet solar battery, for example, a porous film of a metal oxide semiconductor, such as titanium oxide formed on a glass substrate with transparent electrode such as ITO, is treated with an aqueous solution of titanium tetrachloride, and then a sensitizing coloring matter is adhered to the surface.

Title: Semiconductor memory
Inventor: TANBA NOBUO
IPC: G11C29/00
Filed: 1992-05-01
Abstract: PURPOSE:To maintain the high speed of operation regardless of the presence of defect saving by using a MOBFET and switching the transfer path of an address signal with a redundant signal and outputting a defect signal with an auxiliary circuit. CONSTITUTION:The redundant signal is supplied to the gate of a P channel type MOSFET QP through an N channel type MOSFET QN and an inverter circuit IV. Then, when the redundant signal is a high level, both transistors QN and QP are turned on and when a low level, turned off. In such a case, in the state of cutting a fuse, the redundant signal becomes the low level and the transistor QP1 is turned off and an inout signal ELC1 is not transferred to an output terminal OUT1. At this time, the transistor QP2 is turned on and the input signal ELC2 is outputted to the output terminal OUT2. Then the defect circuit having the redundant signal is switched to the corresponding auxiliary circuit and the high speed of operation is maintained since the number of logic stage is made equal regardless of the presence of the defect saving.

Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain the subject new structure capable of combining arbitrary incompatible polymers, having synergistic functions and characteristics, by blending two or more incompatible polymers to form an ultra-microphase structure.

Title: Automatic transmission control method for gear type transmission
Inventor: TAKEYAMA EIJI
IPC: B60W10/00
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To eliminate uncomfortable deceleration feeling and abnormal racing of an engine at the time of up-shift so as to improve operational performance by reducing torque to change gear near no-load by retarding the ignition timing of an engine and changing a throttle opening, and then increasing the engine torque. SOLUTION: In a gear change command for up-shift, the ignition timing retard control and the throttle control are jointly used to conduct the engine torque down control (S1-S4). A command for starting disconnection of a dry type single disc clutch is given to completely disconnect (S11-S13). Aiming at the complete disconnection timing, the engine torque is reduced near no-load, and after the clutch is completely disconnected, a select shift actuator is operated to shift up a gear transmission (S15). The clutch is completely connected to return the torque to the engine torque interlocking with an accelerator pedal (S16-S19). Thus, a decleration feeling can be relaxed to eliminate uncomfortable feeling.
