摘要： An ultrasonic motor capable of being accurately step-driven comprises a vibrating member piezoelectrically vibrated for driving and halting a movable member. A driving wave is generated for vibrating the vibrating member to drive the movable member, and a halting wave is generated for vibrating the vibrating member to halt the movable member. The driving wave can be either a travelling wave or a standing wave, and the halting wave is a standing wave. The movable member is divided into a plurality of portions, and when the vibrating member is driven by the halting wave, the portions of the movable member become centered at respective nodal portions of the standing halting wave, causing the movable member to stop rotating so that the ultrasonic motor can be accurately step-driven.

摘要： An ultrasonic motor utilizing flexural travelling wave components. A ball bearing is constituted by the inner ring, the balls, and an outer ring provided with a groove similar to the ball positioning groove of the inner ring, at a position where the ball are interposed. A rotor is provided inside the amplifying projections which are formed in the vibration member. A coil spring is provided in order to bring the rotor and the projections of the vibration member into pressure contact with each other. A spring pressing seat having a groove for receiving the other end of the coil spring is fixed to the support pin, with the coil spring and the support pin centered. The coil spring receiving groove of the inner ring and the coil spring are positioned so as not to share the same vertical plane with the ball. In this manner the thickness of the ultrasonic motor can be reduced.

摘要： A control portion always monitors a present-position signal from a position sensor and monitors whether the present position of a moving body is a desired position, or not (Step 101). In the case where the control portion detects that the present position of the moving body reaches the desired position, the control portion generates a stop command signal and gives the stop command signal to an oscillation drive circuit (S102). Then, the control portion checks whether overshooting occurs, or not (S103), and in the case where the control portion judges that overshooting occurs, the control portion retains a stop command signal as it is for a stop command retaining time t (S104). After the stop command retaining time t elapses, the control portion gives a reverse command signal to the oscillation drive circuit to conduct reverse operation (S105). After Step S105, the control is returned to Step S101 and the above operation is repeated. Then, in the case where the control portion judges that overshooting does not occur in Step S103, position correcting operation is completed.

摘要： In a temperature gradient adjustor for a temperature-compensated electronic watch, the temperature gradient adjusting range can be widened without any drop in the temperature gradient adjusting resolution of a temperature sensitive oscillator by adding a roughly temperature gradient adjusting variable frequency divider for variably dividing the frequency of the output of a temperature sensitive oscillator and by operating the temperature gradient adjustor at a value which is prepared by adding a constant numerical value to temperature gradient adjusting numerical information.A constant voltage supplying to a temperature sensitive oscillator can be finely adjusted from external side so as to optimize a linearity of frequency versus temperature characteristic.
