Abstract

PURPOSE: To reduce the temperature variation with the control without overshoot, when the temperature decreasing width is smaller than the control temperature which is objective of the thermister, by enabling to keep the temperature of the vessel to objective temperature.
CONSTITUTION: The gate circuit of the thyristor B consists of the thermister D for temperature detection of the temperature set circuit E, and resistors 16, 18 and 5 constituting the bridge circuit, and the thyristor B performs power application control of the heater A. The transistors 7, 11 operated with the potential difference between the nodes c and d of the bridge circuit make conductive the thyristor B when the detected temperature of the thermister D is lower than the first set temperature, and the thyristor B is interrupted when higher than the set temperature. Further, when the detected temperature of the thermister D is less than the second set temperature lower than the first set temperature, the thyristor B is controlled with Tr14 unitl is reaches the third set temperature higher than the first set temperature. The second set temperature is set with the bias resistor 16 connected in parallel with the thermister D.
