PURPOSE:To form a tantalic acid lithium oscillator with high accuracy by turning clockwise the long side for a prescribed angle from the Y axis within the Y-Z plane, and bringing the ratio of the long side to the short side of the major plane to a prescribed value or over. CONSTITUTION:The secondary oscillation is suppressed sufficiently, furthermore the oscillator with small size and a low CI value is obtained by bringing the ratio of the long side to the short side to >=2, in a rectangular oscillator where the long side of the major plane of an X-cut plate of the oscillator 1 is turned clockwise by 43 deg. or 63 deg. from the Y axis. Thus, the oscillator is miniaturized, the CI value is decreased and the spurious component due to the secondary oscillation is suppressed remarkably. |
