Abstract

PURPOSE: To avoid the repetition of unstable ON-OFF which is the operation in response to slight conditional change, by the output of a logic circuit for the output control signal in response to the output of a comparator and by inverting the output control signal after a set time designated with a timer circuit.
CONSTITUTION: A bridge circuit consisting of resistors R1...R3, resistance thermometer bulb RT being a state detector, variable resistor VR being a setter, and power supply E, produces an output proportional to the resistance value of the resistance termometer bulb RT between the sliding point of the resistor VR and resistors R2, R3. This output is fed directly to a comparator 1 and to comparator 2 via the resistor R4, and the comparator 2 responds to the output of the bridge circuit and the output of the comparator 2 controls the start of operation of a timer circuit 3. Further, NAND circuits 4...7 output an output control signal in response to the output of the comparators 1 and 2 and the output control signal is inverted with the output of the circuit 3 after a set time designated with the circuit 3. Thus, unstable ON-OFF state which is the operation in response to slight conditional change can not be repeated.
