摘要： A piezoelectric drive device includes a piezoelectric actuator and a rotation transfer device. The piezoelectric actuator includes a vibrator and a rotor that is rotated in one specific direction by the vibrator. The rotation transfer device transmits rotational energy from the rotor to a driven rotating body, and includes an elastic device that stores rotational energy and a rotation limiting device having a drive wheel and a driven wheel. The rotation transfer device allows the driven wheel to rotate a specific angle, and restricts driving the drive wheel. The elastic device and the rotation limiting device are disposed so that rotational energy transmitted from the rotor is transmitted through one to the other of the elastic device and the rotation limiting device. The rotor, the elastic device, and the rotation limiting device render a serial path for transmitting rotational energy.

摘要： A generally diamond-shaped detection electrode is formed in the approximate center of the piezoelectric element. The strain resulting from the bending secondary vibration mode in the vicinity of the detection electrode is minimized because the detection electrode is formed in such a manner as to include a vibrational node of the longitudinal primary vibrational mode and a vibrational node of the bending secondary vibrational mode. As a result, when the phase difference between the drive signal and the detection signal is detected, the effect of vibration in the bending secondary vibration mode on the detected phase difference can be suppressed and a single drive frequency can be determined with respect to a prescribed phase difference. Thus, the drive performance of the vibrating body with respect to a driven body (i.e., a body driven by the vibrating body) can be reliably improved because, by controlling the drive frequency such that the phase difference equals a prescribed value, the vibrating body can be made to vibrate at a desired frequency and vibrate in such a manner that the desired vibration components are achieved in each vibration mode.
摘要翻译：大致菱形检测电极形成在压电元件的大致中心。由于检测电极以包括纵向主振动模式的振动节点和弯曲次级振动模式的振动节点的方式形成，所以由检测电极附近的弯曲二次振动模式产生的应变最小化。结果，当检测到驱动信号和检测信号之间的相位差时，可以抑制弯曲二次振动模式下的振动对检测到的相位差的影响，并且可以相对于规定的规定确定单个驱动频率相位差。因此，通过控制驱动频率使相位差等于规定值，能够可靠地提高振动体相对于被驱动体（即，被振动体驱动的身体）的驱动性能，振动体可以以期望的频率振动并以使得在每个振动模式下实现期望的振动分量的方式振动。

摘要： To provide a structure capable of performing a correction which surely and easily turns a date display back by rotating a 1st date indicator and a 2nd date indicator in both positive and reverse directions. A timepiece with a calendar mechanism possesses a 1st date indicator, a 2nd date indicator, and a date intermediate wheel which rotates the 2nd date indicator by a rotation of the 1st date indicator. Calendar shift teeth of the 1st date indicator possess a positive rotation unlocking part and a reverse rotation unlocking part. When a rotation center of the 2nd date indicator is defined as “CDA”, a rotation center of the date intermediate wheel as “CMD” and a straight line passing through the “CDA” and the “CMD” as “LDM”, a disposition of the calendar shift teeth before the 1st date indicator is unlocked in a 1st direction and a disposition of the calendar shift teeth under a state that the 1st date indicator has been finished to be unlocked in the 1st direction are axisymmertic with the straight line “LDM” being made a reference line.
