摘要： A timepiece has a wheel and pinion mechanism having upper and lower shafts rotatably mounted in bearings which are fixed in a pair of spaced apart plates. The bearing fixed in one plate has a cylindrical portion which surrounds the pinion portion of the wheel and pinion mechanism and which is spaced therefrom a slight distance which is sufficiently small to enable the pinion portion to abut the inner wall of the bearing cylindrical portion in the event the wheel and pinion mechanism tilts on its lower shaft a predetermined amount from its intended orientation thereby preventing falling of the mechanism during assembly.

摘要： A wristwatch comprises a watch movement having an outwardly curved frame portion, and a micro motor mounted on the watch movement. The micro motor comprises a curved magnetic core, a coil wound on the magnetic core, and a stator connected to the magnetic core to define therewith a closed magnetic flux path and having an opening therein in which a rotor is rotatably disposed. The magnetic core is curved outwardly with a curvature similar to and conforming to that of the outwardly curved frame of the watch movement, and the curved magnetic core overlies the curved frame of the watch movement so that no wasted space exists therebetween. The stator comprises a pair of stator pieces each connected at one end to a respective end portion of the curved magnetic core and the stator pieces have curved side edge portions extending at least partly along the curvature of said curved mangetic core to thereby form a compact overall assembly.

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.

摘要： A timepiece in which a vibration member starts vibration at an alarm time to let a person know the alarm time. The timepiece comprises a case having a shape of thin, small-sized wrist watch form, timekeeping circuit for counting a present time, alarm circuit for setting alarm time, detection circuit for detecting a coincidence a present time with the alarm time and the vibration member actuated at a set time to indicate time. The vibration member comprises a ultrasonic wave motor and an eccentric weight wheel driven by the ultrasonic motor and having its center of gravity deviated from its axis. The whole timepiece is vibrated by the unbalanced centrifugal forces produced by the turn of the weight wheel at the set time to indicate the time.

摘要： A standing-wave type ultrasonic motor utilizing flexible standing-wave components. 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.
