Title: Switching stabilizing power supply device
Inventor: KAMIJIYOU KUNIO
IPC: H02M3/335
Filed: 1980-03-10
Abstract: PURPOSE:To simplify the constitution of a phase control circuit, by connecting a base potential control capacitor between the base and the emitter of the main switching transistor (TR) and at the same time connecting a capacitor charging circuit between the base of TR and a rectangular wave power source. CONSTITUTION:No current flows to the main switching TRQ1 when the rectangular wave output Vin supplied from the inverter IN has the negative polarity; and thus the capacitor C2 is charged up to the voltage VC via the resistance R6 and the diode CR4. When the voltage Vin is inverted to the positive polarity, the TRQ1 does not conduct since the voltage VC keeps the base positive to the emitter of the TRQ1. When the detection output voltage Vout of the differential amplifier A becomes higher than the reference voltage of the Zener diode ZD, the capacitor C2 is discharged to be then charged to the opposite polarity via the diode CR5 and resistance R7. As a result, the TRQ1 conducts to flow the current IQ. The discharging time of the capacitor C2 is short and long when the current flowing to the collector of TRQ2 of the amplifier A is large and small, respectively. Accordingly, the time of conduction of the TRQ1 becomes short and long when the voltage Vout is higher and lower than the reference level, respectively. Thus a control is secured to obtain a constant product of the voltage time.

Title: Light sensor device and manufacture thereof
Inventor: TAKAHASHI ATSUSHI
IPC: H01L27/146
Filed: 1989-02-08
Abstract: PURPOSE:To obtain a device of this design high in yield and reliability by a method wherein a lower wiring is formed in a two-layered or more conductive layer at least at a contact hole or around it, and a surface contamination layer is constantly and uniformly removed to obtain a uniform and low contact resistance. CONSTITUTION:A lower wiring or an electrode 11 is formed of a laminated body composed of metal layers 11a and 11b different from each other in kind. Then, the lower wiring is patterned into a specified shape through etching, and an insulating layer 13 is deposited on the whole face of the lower wiring. The insulating layer 13 is etched using a photoresist 17 as a mask to form a contact hole 16. Then, a lower electrode exposed at the contact hole 16 is cleaned through etching such as a dry etching by the use of a mixed gas of CCl4 and O2 or a wet etching by the use of a mixed solution of ceric ammonium nitrate, perchloric acid, and water. And, after cleaning, only a Cr layer 11b can be selectively cleaned in the region of the contact hole 16 and an Al layer 11a of a base is left unchanged, so that a contact resistance uniform and low can be obtained.

IPC: G03B21/11
Filed: 1985-02-19
Abstract: PURPOSE:To prevent a film from damaging by providing a means which switches a guide member between a guide state and a non-guide state at specific timing. CONSTITUTION:A detecting means 36 provided nearby a film guide roller 11 at the side of the guide member 17 irradiates the rays of light and detects light reflected by the leader part of the microfilm F, thereby detecting the passing of the leader part of the film F. The switching means 34 places the guide member 17 in the non-guide state more quickly. While the guide member 17 is in the non-guide state, the film F never damages even if conveyed at a high speed and stopped abruptly, so that the film F is retrieved in a short time.

Title: Action control command device of power drive section for servo motor
Inventor: KANO MINORU
IPC: H02P7/291
Filed: 1987-02-13
Abstract: PURPOSE:To eliminate the speed response delay caused by a braking dead zone, by correcting the drive command of a servo motor by a value equivalent to the braking dead zone of a power circuit when braking control is required. CONSTITUTION:A control command means 10 outputs a PWM command and a rotating direction command making a comparison between the target signal and the feedback signal. A power element operation signal generating means 11 outputs a signal to operate a power element of an H-bridge circuit 13 in compliance with the PWM command and rotating direction signal. A control command means 10 works out the current command so that the speed command may agree with the feedback speed in each definite period. By discriminating whether this current command is positive or negative, the correction amount of braking dead zone is set to 0 if discriminated positive. In this way, high- precision speed control with least speed response delay can be implemented.

IPC: H04B1/04
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To protect a device from its load variance without changing the power that is supplied to the device by detecting the load variance and performing the switching between the connected and non-connected states of a protecting load, based on the detection result of the load variance. SOLUTION: Detection terminals 12 and 13 monitor the connection state between an antenna 11 and an input circuit which circuits the signals to the antenna 11. When the antenna 11 is stored completely, the terminal 13 is electrically connected and transmits a ground signal to a changeover switch 14. When the antenna 11 is completely extended, the terminal 12 is electrically connected and also transmits a ground signal to the switch 14. When the antenna 11 is neither completely stored or extended, both terminals 12 and 13 are not electrically connected and transmit no ground signal to the switch 14. Then the switch 14 performs switching between the connected and non-connected state of a device protecting load 16 to the output side of a device 17 in response to the signals which are received from the terminals 12 and 13.

Abstract: PURPOSE:To control an EGR amount optimum from the time when an engine is started despite tolerance of parts and the secular change, and secure the EGR amount of max limit within the extent in which no surge appears. CONSTITUTION:An EGR valve 24 driven by a stepping motor 25 is installed at an EGR tube 23. The fundamental degree of opening of EGR valve is stored in a ROM 34, while a correction value for the EGR valve 24 in accordance with the engine 1 operating condition is stored in a backup RAM 36.
