Filed: 1987-02-24
Abstract: PURPOSE:To obtain the base driving circuit of a simple constitution by providing a current transformer having one secondary winding which induces a current with the current of the main line of a transistor (TR), a means which rectifies the secondary current on a half-wave basis and applies the current to the base, a switch which short- circuits this means and applies a reverse bias, and a start current switch between the collector and base. CONSTITUTION:When an FET 6 is turned on by a signal source 31, a base current flows to the primary winding 1a of the current transformer 1 and a main TR Q13. The winding ratio 1a/1b of the current transformer 1 is set nearly equal to the hFE of the Q13 and its black point side is plus. The Q13 turns on with the current flowing through the winding 16, a diode 2, the base and emitter of the Q13, and a reverse bias power source 4 and the power source 4 charges itself. The signal source 13 is turned on to turn of the FET 6 with the positive signal of a signal source 15 and then turns on an FET 5, and consequently winding 1b is short-circuited to apply a reverse bias to between the emitter and base of the Q13, which turns off speedily. A diode D14 allows a negative feedback current to flow when a load 12 is inductive, and a D11 and a resistance 16 are used to reset the current transformer 1. In this constitution, a driving power source reduces unnecessary bias power source capacity.

Abstract: PURPOSE:To provide an oscillation circuit operating at a low voltage and low in power consumption and small in the area occupied by a chip by providing an oscillation block with a depletion type N-channel MOS transistor(TR) in cascade connection to a P-channel MOS TR connecting to a power source. CONSTITUTION:A switching signal C is zero in the initial state, a TR ND21 is conductive and an oscillation block 2 is operated.

Moreover, an output level of a NOR circuit R31 goes to 0 with the signal C via an inverter I31 and an output level of NOR circuit R32 goes to 0 by the signal S and both oscillation blocks 1, 2 stop their oscillation. When the signal S goes to 0 at a time T2, output levels of the circuits R31, R32 go respectively to 1 and 0 and feedback resistors TRs P33, N31 are conductive. Thus, the oscillation block 1 starts its oscillation and a clock CK is outputted via a NOR gate R33. As a result, the circuit is operated at a low voltage with low power consumption and area of the circuit occupied in the chip is small.

The high density ethylene polymerized body is not fused when in use and the flow quantity and the flow rate of heat medium in use does not change. Therefore, it is possible to obtain the heat accumulation that does not deteriorate in performance even after a long period of use.
