IPC: H01H9/36
Filed: 1990-07-11
Abstract: PURPOSE:To improve cutoff performance by dividing the fixed contact of a plate-shaped metal arc-extinguishing grid into two or more in parallel in the length direction, folding the divided metal arc-extinguishing grids into U-shaped metal arc-extinguishing grids, and directing the folded ends of the U-shaped metal arc-extinguishing grids to the open space. CONSTITUTION:When a moving contact 6 is opened, an arc 12 is generated across the moving contact 6 and a fixed contact 8a. The arc 12 is then moved to divided U-shaped metal arc-extinguishing grids 13a to become a moving arc 12b. The moving arc 12b is driven in the direction apart from the open space of contacts 6a, 8a by the mutual action of the magnetic field generated by the current flowing in the moving arc 12b and the current flowing in the divided U-shaped metal arc-extinguishing grids 13a and the current flowing in the moving arc 12b. The moving arc 12b passes many divided U-shaped metal arc-extinguishing grids 13a, its length is extended, and the moving arc 12b is cooled and smoothly extinguished.

Title: Hand deflection warning device of camera
Inventor: SUZUKI YOSHIJIROU
IPC: G02B7/28
Filed: 1980-12-24
Abstract: PURPOSE: To warn a drop of the focusing accuracy due to hand deflection, by constituting so that an alarm is raised in accordance with the charge storage amount of CCD of a focusing detecting element within a prescribed time.  
     CONSTITUTION: A CCD controlling circuit receives a clock pulse from an oscillator OSC, and sart to charge a capacitor CI through an FF and a transistor TR by a reset signal ϕR. This charging voltage is compared with reference voltage VREF by a comparator C. If luminance of an object to be photographed is sufficient, TR is tuned on by a transfer start signal ϕT before the charging voltage of the capacitor Ci reaches the reference voltage VREF. In case when the luminance of an object to be photographed is low, ϕT is delayed, therefore, the charging voltage of the capacitor CI exceeds VREF, and an alarm such as a buzzer, etc. is raised. In this way, a drop of the focusing accuracy due to hand deflection is warned.

Abstract: PURPOSE:To switch a system clock at high speed by forming an oscillating pulse by multiplying the pulse of a low frequency while using a PLL circuit, and outputting the clock corresponding to a low-speed/high-speed mode and the stability degree of a circuit. CONSTITUTION:At a clock pulse generating circuit built in the microprocessor, an oscillation circuit XOSC forms the oscillating pulse of the comparatively low frequency corresponding to the low-speed operating mode and the PLL circuit multiplies this pulse as a reference frequency signal so that two kinds of clock pulses DV1 and DV2 for the high-speed operating mode can be formed. When the microprocessor is set in the low-speed operating mode, clock pulses CK1 and CK2 of the comparatively low frequency are outputted and when any event requiring a high-speed operation is generated, multiplexers MUX 3 and MUX 4 continuously output the clock pulses for low speed until the PLL circuit is turned to an operating state and stabilized but when the PLL circuit is stabilized, clock pulses for a high-speed operation are outputted.

Title: Control circuit device for motor
Inventor: NOMURA KATSUYOSHI
IPC: H02P27/02
Filed: 1980-12-24
Abstract: PURPOSE:To stably and effectively perform the controlling operation of a control circuit device for a motor by suitably selecting the constant of a charging circuit of a capacitor, thereby controlling the period of time when the recharging voltage reaches the threshold voltage of an inverter. CONSTITUTION:When a start switch MS is closed, the input side of an inverter INQ11 is grounded, and the output side is transferred to a high voltage. Then, a transistor TrQ1 is continuously conducted via the INQ13 and a resistor R12. A photocoupler PC1 continuously emits a light. A current is supplied to a motor (not shown), thereby opening an automatic door DR. When the output side of the INQ11 is transferred to high voltage, a differential pulse voltage is applied to the input side of the INQ16 via a capacitor C6 and a diode D20, and the output side is instantaneously transferred to low voltage. Thus, the capacitor C4 is discharged, and when the output side of the INQ16 is thus reset to the high voltage, the capacitor C4 is recharged. When the charged voltage reaches the threshold voltage of the inverter, the output side of the INQ15 is transferred to the low voltage, and the diode D1 is conducted, thereby the TrQ1 is recovered and interrupted. Thus, the current supply to the motor is interrupted.

Abstract: PURPOSE:To copy an original to an ordinary paper with a simple constitution and improve recording density by making the moving speed of a plate writing surface during exposure scanning higher than that at the time of returning to the home position, namely, at the time of nonexposure of the plate writing surface. CONSTITUTION:Though the moving speed of a plate writing surface 1 at the time of exposure scanning is a fixed value which is determined by the rotating velocity of a copying device-side photosensitive body 7 and the magnification of the image, which is formed on the photosensitive body 7, of the plate writing surface 1, that of the plate writing surface 1 for return to the home position is optional.
