    • A circuit that transfers data between a first clock domain using a first clock and a second clock domain using a second clock synchronized with the first clock. The circuit comprises a data holding circuit operating at the first clock, an enable signal generation circuit connected to the data holding circuit. Preferably, the data transfer circuit includes an edge signal generation circuit connected to the data holding circuit, the edge signal generation circuit generating an edge signal allowing the data holding circuit to receive and send the data when edges of the first clock and the second clock align, and applying the edge signal to the data holding circuit.
    • 使用与第一时钟同步的第二时钟,使用第一时钟和第二时钟域在第一时钟域之间传送数据的电路。 电路包括在第一时钟工作的数据保持电路,连接到数据保持电路的使能信号发生电路。 优选地,数据传送电路包括连接到数据保持电路的边沿信号产生电路,边沿信号产生电路产生边沿信号,允许数据保持电路在第一时钟和第二时钟的边缘对准时接收和发送数据 ,并将边沿信号应用于数据保持电路。

    • In an ultrasonic motor wherein a driving signal is applied to an electro-mechanical energy conversion element provided in a vibration member to thereby excite flexural vibrations of the same shape in the two different planes of the vibration member with a phase difference in time and thereby create rotational motion on the surface of the vibration member, thus frictionally driving a movable member which is in pressure contact with the vibration forming surface, electro-mechanical energy conversion elements for exciting the flexural vibrations are each disposed at a position whereat the sum totals of strains created in the electro-mechanical energy conversion elements are substantially equal to each other.
    • 在超声波马达中,其中驱动信号被施加到设置在振动部件中的机电能量转换元件,从而以相位差在时间上激发振动部件的两个不同平面中相同形状的弯曲振动,由此产生 在振动构件的表面上的旋转运动,因此摩擦地驱动与振动形成表面压力接触的可动构件,用于激发弯曲振动的机电能转换元件分别设置在总和应变 在机电能量转换元件中产生的基本上彼此相等。
