Abstract
PURPOSE:To obtain a small-sized crystal vibrator having a high resistance to shock, by etching the vibrator so that the position in the side of the +x face of the inside of the tuning fork out of parts, where stress generated near the groove bottom is concentrated, is placed in the arc part of the groove bottom when an excessive shock is applied. CONSTITUTION:If a quartz vibrator is subjected to the chemical etching work for four hours, a very small quantity of the intersection of the natural face to the left branch, namely, a +x face side 3 is placed in the arc of the groove bottom. Thus, the part where stress is concentrated very much is brought to the part of an R of the groove bottom where the concentrated stress is scattered, and a quartz vibrator strong against shock is obtained.
