Abstract

PURPOSE:To stabilize frequencies and improve aging characteristics by making the two excitation electrodes disposed at the base part of a tuning fork mutually parallel to the two planes assuming the tuning fork type of a vibrator and so designing the vibrator that no excitation electrodes are provided on lateral portions, in a 5 deg.X-cut tuning fork type crystal vibrator.
