Abstract

PURPOSE:To obtain excellent frequency-temperature characteristics by improviding the electrode structure of thickness-width slip crystal vibrator to reduce the equivalent impedance, and by properly combining the cut-out angle and dimension. CONSTITUTION:In a thickness-width slip crystal vibrator of which Y plate is cut out from a plate rotated 34 deg. to 36 deg. about X-axis, as rotating axis, respective two electrodes 9, 10 are provided on the main surface vertical to Y- axis cut out in the range of -49 deg. to -52 deg. from Z-axis on the side face, and perpendicular to Y-axis, and counter electrodes 11, 12 of main surface are provided in the reverse polarity each other. When the ends of counter electrodes are disposed to be parallel to Y-axis, excitation in the vibration mode of (1,1,1) is possible, so that the equvalent impendance may be reduced. In addition, by making the side ratio of the vibrator smaller than 0.3 excellent frequency-temperature characteristics may be obtained.
