Patent JP-S56122236-A (JP)
Title: Logic gate circuit
Inventor: KIYOZUKA NOBORU
IPC: H03K19/013
Filed: 1980-02-29
Abstract: PURPOSE:To obtain a logic gate that excels in both the speed and the output pressure resistance, by providing a means to cut off an active pull-down circuit. CONSTITUTION:When the input changes to ''H'' from ''L'', the transistors Q2 and Q5 are turned on with the output out going to be ''L''. In this case, however, Q7 is turned on simultaneously with the ON of Q2, and the accumulated electric charge of Q4 is discharged via the collector of Q7 to be flowed into the resistance R5. Owing to this current, the emitter potential of the active pull-down transistor Q6 increases during an inversion of input from L to H. Thus Q6 is not turned on when Q5 is going to be turned on due to the ON of Q2. Accordingly the emitter current is not branched from Q2 via Q6 but supplied in the form of the base current that drives Q5.

Title: Power unit for light source of copying machine
Inventor: ARAI HARUO
IPC: G03G21/08
Filed: 1984-02-14
Abstract: PURPOSE:To turn on an electroluminescent (EL) element for destaticizing efficiently by turning on and off a switching element with timing pulses. CONSTITUTION:Output timing pulses of an encoder 8 are used as the on-off control signal of the switching element such as a driver transistor (TR) 9 connected to the primary side of the power transformer 5 of the EL1. Consequently, the output of the encoder 8 is led out through resistances R1 and R2 independently of a main circuit and those timing pulses are transmitted to the base of the TR9. Consequently, the TR9 is turned on and off at 420Hz to turn on and off the primary current of the power transformer 5, and an alternating current of 420Hz is therefore induced at the secondary side of the power transformer 5, thereby turning on the EL1.
