摘要： A traveller having two ultrasonic motors, each of which movable member drives the driving wheel respectively. The ultrasonic motor comprises a vibrating member, a moving member and a pressure regulating member. The driving circuit sends signals to turn the ultrasonic motor, which turn the moving memeber to turn the driving wheel. With the driving wheel turning, the traveller travels freely in any direction. Each of two ultrasonic motors receives respective signals to travel freely in any direction as a effect.

Protuberances are provided nearly at every other intermediate positions of the loops and the nodes of flexible standing-waves generated in the vibration member by the piezo-electric element or the electro-strictive element, and a moving member is brought into pressed contact with the protuberances so as to be frictionally driven. A standing-wave type ultrasonic motor is driven in the forward direction and in the reverse direction while fulfilling the reduction in size, stabilization in performance and improvement in efficiency.Furthermore, an analog-type electronic timepiece is obtained using display means that is driven by the standing-wave type ultrasonic motor, featuring reduced size and thickness.

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.
