Abstract

A shock absorbing mechanism for protecting a fragile quartz crystal includes a Teflon coating on the internal surface of the crystal enclosure. The enclosure is provided with a plurality of detents arranged so that when the crystal is shocked in its most fragile plane a plurality of these Teflon coated detents are struck simultaneously to distribute the shock across the surface of the crystal.

1. 1. A shock absorbing mechanism for protection of a planar crystal device against impact with a crystal enclosure wall, said crystal device having opposed major surfaces, said shock absorbing mechanism comprising:shock absorbing means having a plurality of deformable protuberances for contacting one as said major surfaces when said crystal device is subjected to mechanical shock; andcarrier means for holding said shock absorbing means between one of said major surfaces and said enclosure wall so that said plurality of deformable protuberances contact one of said opposed major surfaces substantially simultaneously when said crystal device is shocked by a force exceeding a predetermined magnitude in a direction toward said shock absorbing means and substantially perpendicular to said opposed major surfaces.
