Abstract

PURPOSE:To lower the frequency by grinding the bottom of the kerf of the tuning fork type oscillator after forming the electrode through the vapor deposition means. CONSTITUTION:The electrode is formed by the vapor deposition means, and then the kerf bottom 14 of the tuning fork type oscillator 11 is ground. In this way, a steady control of the frequency is possible without lowering the characteristics of the oscillator 11.
