Abstract

This paper presents the investigated results of a newly designed T0-8 type metal casing crystal oscillator module applied to a high accuracy clock. Typical construction of this oscillator module and its characteristics are shown. Here described the fundamental principle of newly developped mass production method to accomplish a plano-convex quartz crystal blank without cut angle error and to realize frequency adjustment automatically. A certain design method to avoid the behavior just like "an abnormal frequency change" due to the shape of plano-convex is presented. Finally, the stability as a clock is evaluated by computer simulation, resulting in the accuracy guaranteed quartz crystal clock with a very small accumulated error for four seasons.
