Abstract

PURPOSE:To suppress the subresonance of bending oscillation, with increased Q- value without lowering the mechanical strength of support, by preventing the leakage of oscillation energy from the support, in an X-cut quartz oscillator. CONSTITUTION:The quartz oscillator is formed so that the ratio of sides of a rectangular quartz plate 1 in which the longitudinal oscillation mode is used and the cut azimuth (xyt) theta (according to IRESTD. 1949) is defined, is 0.1-0.2, and the cut angle is 0 deg.-5 deg.. Further, this is supported with a plurality of points on a straight line rotated by 10 deg.-13 deg. according to the value of ratio of sides counterclockwise the center line of Z(Z') axial direction through the center line on the quartz plate, or the edge of the quartz plate 1 on the straight line.
