Title: Ic output latch circuit
Inventor: TAKAHASHI KAKAMASA
IPC: H03K19/007
Filed: 1978-12-28
Abstract: PURPOSE:To hold the output state of IC constant by applying a constant clear level to the clear input terminal of IC when a power voltage is below a prescribed value. CONSTITUTION:As a power voltage increases gradually, transistor 9 conducts. As this point in time, Zener diode 7 and transistor 8 are both OFF. Consequently, a current flows through a light emitting diode in photocoupler 10 and a photo transistor in photocoupler 10 is turned ON. Emitter-collector voltage VCE with the photo transistor ON is applied to clear input termianl 4 of IC1. As a result, IC1 is forcibly reset and its output state is changed into a reset state. When the voltage increases high enough for IC1 to operate normally, the forcible resetting of IC1 is released and supplying a clock pulse to clock input terminal 3 starts normal operation. When the power voltage lowers, the circuit operation is reversed.

Abstract: PURPOSE: To realize positive-positive printing and negative-positive printing in one machine simultaneously, by uniformly charging the photosensitive plate, applying first image forming radiation, and applying second image forming radiation and AC destaticizing, then exposing the entire surface.  
     CONSTITUTION: A photosensitive plate A having photoconductive layer 2 and insulating layer 3 on a conductive supporting body 1 is, for example, negatively charged by a corona discharger 4 in dark place, and first optical image is radiated, then a positive charge 32 remains in the boundary of the layer 3 in the bright part and is unchanged in the dark part.

Filed: 1983-09-02
Abstract: PURPOSE:To prevent softening of packing by providing a recess at the valve receiving section while making lift of delivery valve equal to thickness of packing and said recess section. CONSTITUTION:A recess 6h is provided at the valve receiving section of a delivery valve board 4 of head cover 6.
