Abstract: PURPOSE:To improve the response of an oscillating circuit and to minimize the time lag caused by the control by starting and stopping the oscillating circuit by means of an impedance change-over circuit and always supplying electric power to the driving circuit. CONSTITUTION:An impedance change-over circuit 11 is connected with a tank circuit 4 in parallel. When the switch 7 of this circuit 11 is closed and a resistance 9 is connected with the circuit 11, the impedance of the circuit 11 becomes smaller and the sharpness Q of the oscillation of the circuit 4 is dropped and, as a result, the circuit 4 is stopped, but a driving section 36 comoposed of FETs 10, 16, and 23 and a TR28 remains activated because power supply is made to the driving section 36 as in the case of oscillating condition. When the switch 7 is opened and the resistance 9 is cut off from the circuit 11, the impedance of the circuit 11 becomes larger and the sharpness Q of the oscillation of the circuit 4 becomes a prescribed value and, as a result, this oscillating circuit makes oscillation. In this way, the oscillating circuit is quickly actuated so as to make stable oscillation when the switch 7 of the circuit 11 is set to the opened condition.
