Title: Driving circuit of transistor
Inventor: SHIMIZU TOSHIHISA
IPC: H03K17/0412
Filed: 1983-04-20
Abstract: PURPOSE:To attain high speed switching with low loss by connecting a Zenner diode to a reverse bias current flowing circuit using a transistor on the secondary side of a pulse transformer driving the main transistor of a semiconductor switch. CONSTITUTION:A signal from a driving current supplying circuit 3 is supplied to a main transistor TR1 through the pulse transformer 4 and the TR1 is turned on. When the driving signal disappears, the transformer discharges exciting energy and is reset, so that reverse current against the driving signal flows in the direction of the emitter of the TR1 base resistor 12 Zenner diode 11. Since the current acts as a reverse bias current of the TR1, the TR1 is quickly interrupted. Since the reset voltage of the transformer 4 is secured by the diode 11, the transformer 4 is simultaneously reset.

IPC: G11B20/00
Filed: 1982-04-26
Abstract: PURPOSE:To eliminate dropout of signals on the same channel at reproduction, by changing the recording location of audio signals of each channel at each track.
