  • Piezoelectric actuator and process for fabricating the same
    Patent number: 5477102
    Abstract: A piezoelectric actuator includes an electrostrictive effect element, a metal case shaped to be cylindrical for housing the electrostrictive effect element, top and bottom caps for covering top and bottom openings of the metal case, respectively, and locating plates fixed at top and bottom portions of the electrostrictive effect element. The locating plates are set in hollow portions formed at center of the caps, so that the electrostrictive effect element is positioned and fixed at the center of the piezoelectric actuator.
