摘要： An ultrasonic motor with increased output power per unit volume is provided by simultaneously driving all of a plurality of polarized segments of a piezoelectric element having a circular disk shape and divided into a multiple of four polarized segments in a circumferential direction. Projections are provided at upper faces of the polarized segments of the piezoelectric element and spaced apart by an odd number of polarized segments. Polarities of adjacent polarized segments are the same and polarities of adjacent pairs are reverse to each other. A first polarized segment group comprises every other polarized segment and a second polarized segment group comprises the remaining polarized segments. By selecting whether phases of alternating voltages supplied to the first and second polarized segment groups are the same or are 180 degrees out of phase, the direction of the motor is determined.

摘要： In a self-excited oscillator circuit, a buffer is connected to an electrode or electrodes, and a buffer and an inverter are connected to an electrode or electrodes. Each of the inverters and and the buffer has a tri-state configuration and is capable of setting an output terminal in a high-impedance state, i.e., turning off an output signal, according to a signal input to a control terminal. Therefore, it is possible to turn off a drive circuit and the ultrasonic motor by setting the inverter in the high-impedance state. It is also possible to change the direction of movement of the moving member by setting one of the buffer and the inverter in the high-impedance state.
