Abstract

PURPOSE:To obtain a high-performance and highly stabilized crystal oscillator with a compact size by giving a slope polishing process or a spherical polishing process of more than two stages to the attenuation region at the spherical part of a crystal oscillator and by scuring a complete enclosure of the oscillation energy.
