Abstract

PURPOSE:To adjust the temperature of a master machine from a slave machine through wireless, by providing a resonance circuit which can set the resonance frequency to a certain position of the sweep band of a sweep oscillating circuit which charges the band in accordance with temperature. CONSTITUTION:A sweep oscillating circuit 2 is driven by a saw-tooth wave oscillating circuit 1. A bias voltage determined by the temperature detected by a thermistor 3 is given to the sweep oscillating circuit 2 by a bias circuit 4. An electromagnetic coupling circuit 5 is connected to a tank circuit 7 of a slave machine 6 by mutual induction, and it is detected by a resonance detecting circuit 8 whether sweep waves are resonated to the tank circuit 7 or not, and a controlling circuit 9 is turned on for detection of resonance but is turned off when resonance is not detected, thus controlling the current in a heating body 10. By this constitution, the resonance point of the tank circuit 7 is controlled to adjust the temperature of a master machine through wireless.
