IPC: H03K21/40
Filed: 1986-10-22
Abstract: PURPOSE:To prevent the effect of fluctuation in a power voltage by detecting early the generation of power failure so as to inhibit the counting of a counter circuit. CONSTITUTION:A voltage level detection circuit 10 detecting the output voltage of a rectifier circuit 4 connected sequentially to an AC power supply, a timer circuit 50 giving an inhibition signal by the output of the circuit 10 or resetting the inhibition signal and inhibition circuits 60a, 60b operated by the inhibition signal and inhibiting the counting of counter circuits 20, 30 respectively are provided. Then a DC voltage before being rectified and smoothed by the rectifier circuit 4 to detect the power failure quickly is detected by the circuit 10 and the inhibition circuit is operated via the timer circuit by the output of the circuit 10. Since the inhibition operating period is independent of the state of power consumption of the internal circuit, the possibility of malfunction due to an error signal from a peripheral equipment is precluded. Since the operation of the output circuit is inhibited at power failure, the power consumption is less.

Abstract: PURPOSE:To perform the temperature control with high accuracy by setting a reference cycle based on the switching action to the proportional control to produce a pulse signal for proportional control when the proportional control is performed in combina tion with the full energization or plural proportional control systems are alternately switched with each other. CONSTITUTION:The reference voltage generators 3b and 4b are connected to the PWM circuits 3a and 4a of the temperature control circuits 3 and 4 respectively in response to the proportional control switching reference temperature (proportion start tempera ture). Then the proportional control is quickly switched to the PWM control after the start up to each prescribed reference temperature with the fully enagized heating.

In addition, the reference cycle generating circuits 10a and 10b are connected to the circuits 3 and 4 to set the reference cycles based on the charging/discharging cycles of each time constant circuit 11. The width of the pulse signals produced based on the oscilla tion cycles produced by the circuits 10a and 10b are controlled in response to the difference between the detection voltage and the target control voltage. Thus the temperature control is facilitated with high accuracy in a simple constitution.
