Abstract

PURPOSE:To improve the support of a quartz oscillator and to enhance the electrical properties of the oscillator, by applying a convex working to the side edge in the longitudinal direction of an oblong quartz plate. CONSTITUTION:A quartz oscillator 5 is produced by applying a convex working to the side edge in the longitudinal direction of an oblong quartz plate that is cut with the definiation of a cut direction (xzt)phi. As a result, the displacing direction of the oscillating 5 is shown by an arrow 6, and the diplacement and the node are shown by the dotted line and the chain line respectively. The displacement 7 of oscillator is enclosed at the center part of the oscillator 5, and the displacement is eliminated at the both ends in the longitudinal direction. In other words, the result of the oscillation analysis obtained by the definte element method is shown in the diagram. Thus UY>>YZ is satisfied between the vertical oscillation displacement component UY and the sliding oscillation component U8, and the displacement UY of the width direction has a bysymmetric form in the longitudinal direction of the quartz oscillator. As a result, the both ends of the oscillator can be firmly fixed to a prescribed case, etc.
