    摘要: A piezoelectric actuator has a zigzag-shaped actuator body, and an expansible piezoelectric element attached to the actuator body. The actuator body has zigzag elements. The zigzag elements are shifted toward and away from each other by expansion/contraction of the expansible piezoelectric elements. The actuator body is expanded and contracted by positional shifting of the zigzag elements.

    摘要: A vibration unit which includes a circular direction vibrator, a liquid detector resonated by the circular direction vibrator, and a vibration transmission member for connecting the circular direction vibrator and the liquid detector and being twist vibrated when the liquid detector is resonated. The resonant liquid detecting device includes a mounting member provided at a location including a node of resonance existing in an intermediate portion of the vibration transmission member and is adapted to suspend the vibration unit in a constant position while the opposite ends of the vibration unit operate as free vibration ends.
