Abstract
An oscillation circuit has an oscillator having a resonant frequency, an amplifier connected to the oscillator, an energizing pulse generator for generating a energizing pulse within a certain range including the resonant frequency, a switching unit for switching between connection and disconnection of the energizing pulse generator and the oscillator, and the amplifier, and a motion command unit for sending a command signal to the energizing pulse generator for starting operation, in which the switching unit connects the oscillator and the energizing pulse generator during a cycle, a half cycle, or several cycles of the energizing pulse generated by the energizing pulse generator starting at a time when the motion command unit sends the motion signal.
