Abstract

PURPOSE:To prevent destruction, by providing fine unevenness or curve on the external shape of the oscillator and avoiding the concentration of distortion energy on a part of it. CONSTITUTION:The external shape is formed with etching when the oscillator 1 is linked to the frame, and fine unevenness or curves are provided on the external shape of the major surface. Thus, the distortion energy at falling shock is scattered to avoid the phenomenon of concentration of distortion energy only a part, allowing to prevent the destruction.
