Abstract

PURPOSE:To control the temperature of heat generating body, by controlling the voltage supplied to the heat generating body by the pulse of the pulse generating circuit and varying the value of resistance of the heat generating body. CONSTITUTION:When the electric potential of the input terminal (a) of the bridge circuit 11 provided with the filament Rf on one side as heat generating body, is positive to the electric potential of the input terminal (b), the interval of output pulse from the pulse generating circuit 60 is not changed and the voltage supplied to the circuit 11 is not changed. When the terminal (a) is negative to the terminal (b), the switching circuit 40 is turned to ON state and the output voltage of the integral circuit 50 is changed. Hereby, the interval of output pulse of the circuit 60 is changed and ON.OFF period of the thyristor 13 is changed. Then, the voltage supplied to the circuit 11 is controlled and the resistance value of the filament Rf is made a desired value and then, desired heating temperature is obtained. When the filament Rb becomes to have a desired resistance value, output voltage is eliminated in the integral circuit and the interval of pulse of the pulse generating circuit 60 is kept constant and then, a prescribed heating condition is maintained.
