Abstract
PURPOSE:To save the power consumption to keep an object temperature of a piezoelec tric substance lower by thermally coupling a pertier element to the piezoelectric sub stance forming an oscillation circuit and using an output of a temperature sensor so as to control the conduction current of the pertier element. CONSTITUTION:A temperature sensor 3 is built in the oscillator 2 including the piezoe lectric substance 1 to obtain an electric signal in response to the ambient temperature. Moreover, one end of a thermal propagation path of the pertier element 4 is coupled thermally with the piezoelectric substance 1 and the other end is coupled with a ther mal balance case 5. The case is enclosed by an insulator 6 so that no heat comes or exits to/from the part other than the case 5. The detection signal of the temperature sensor 3 is given to a control circuit 7 and the direction and magnitude of the current given to the pertier element 4 are controlled in response to the signal to control the ambient temperature of the piezoelectric substance 1 to be lower than the external temperature, such as room temperature 25 deg.C as an object. Thus, the power consumption to keep the temperature of the piezoelectric substance constant in the oven temperature control, etc., is saved and the fluctuation of the oscillated frequency is prevented.
