Abstract: An ultrasonic driving apparatus consists mainly of a digital oscillatory circuit, an amplifier, a detection circuit, a phase difference detection circuit, a register, a data transfer circuit, and a switching circuit. The digital oscillatory circuit is used to drive an ultrasonic transducer at the resonance frequency of the ultrasonic transducer. The amplifier amplifies a driving signal output from the digital oscillatory circuit. The detection circuit detects the phase &thgr;v of an applied voltage and the phase &thgr;i of an induced current from the driving signal applied to the ultrasonic transducer via the amplifier. The phase difference detection circuit detects a difference between the phases &thgr;v and &thgr;i. The register holds digital frequency data with which a frequency at which the digital oscillatory circuit is oscillated is determined, and changes the digital frequency data. The data transfer circuit transfers the digital frequency data to the register.

Abstract: A plurality of handpieces used to perform an operation is connected to a main operation apparatus, which generates a driving signal, through connectors formed on the main apparatus. When an operator holds a handpiece he/she wants to use, an output line over which the driving signal is transmitted is routed to the held handpiece owing to an output of a sensor that detects a change in capacitance stemming from the hold. The operator therefore need not manually set a mode in which the driving signal is applied to the handpiece he/she wants to use. Moreover, a port number assigned to a port to which the output line is routed is indicated on a display device. The operator can readily identify the usable handpiece.
