New Shape Flexural Mode Quartz Crystal Resonator with Suppression of Energy Leakage by Vibration

This paper describes a new shape flexural mode quartz crystal resonator which suppresses energy leakage by vibration. An object of this paper is to propose a new shape resonator which vibrates in a flexural mode and to clarify its frequency characteristics in the calculation and the experiments. Frequency temperature behavior, series resistance versus resonant frequency and resonant frequency versus thickness are also shown in the experiments. The present resonator is found to show excellent electrical characteristics in the frequency range of approximately 200 kHz to 450 kHz.
