Abstract

PURPOSE: To prevent a body to be controlled from changing suddenly in temperature by intermittently exercising temperature control over the body to be controlled without stopping a body to be driven from operating on the whole even if the temperature of the body to be controlled exceeds a set temperature.
CONSTITUTION: The temperature of a body to be controlled is detected by negative- characteristic temperature sensing element 3 of bridge circuit 1, which sends an output signal to relative amplifiers 7 and 8 until the temperature of the controlled body reaches a 1st set temperature, and consequently driving transistor Tr9 conducts to put body 12 to be driven into operation, thereby increasing the temperature of the controlled body. Once the temperature of the controlled body increases over the set value, the output signal of amplifier 7 is eliminated by varying the potential at the output terminal of circuit 1 and the cathode side of diode 11 is held at level H by the output signal of amplifier 8 to apply an oscillation output from low-frequency oscillator 10 to the base of Tr9, thereby driving driven body 12 by the intermittent output signal of oscillator 10. Then, the controlled body is prevented from changing suddently in temperature.
