Abstract

PURPOSE:To miniaturize the shape and to increase the oscillating performance, by positioning the Y plate of crystal thin plate at the position rotated by 46 to 56 deg. taking the X axis as the center, and by forming the shape of the slip vibrating type crystal oscillator with the photo etching method.
