Abstract
Quartz crystal vibrators of small size which vibrate in the shear mode consist essentially of a vibrating portion and a support portion, both of which lie in the same plane. As a consequence, they are readily manufactured on a production basis and can be shaped so as to minimize the effect of variation in ambient temperature.
