  • Acceleration detector
    Patent number: 5539270
    Abstract: The acceleration applied to a selected device such as a magnetic disc drive system can be detected by the use of an acceleration detector having at least one piezoelectric acceleration sensor unit. The sensor unit includes a piezoelectric element, a supporting member for the piezoelectric element and two electrical leads. The piezoelectric element is formed with a pair of elongate sheets made of a piezoelectric ceramic and an intermediate insulation layer interposed between the elongate sheets to generate a voltage difference instantaneously therebetween in response to the acceleration of the acceleration detector. The support member is made of an electrically insulating resin, and has a concave which is formed with side and bottom walls and a top opening. The side wall is provided with a slit in which the piezoelectric element is tightly caught in such a manner as to divide the concave into two open-chambers and be supported by the support member in a cantilever fashion.
