Abstract

PURPOSE:To adjust oscillation frequency and temperature characteristics simply and clearly, by evaporation-adhering the +Z' face as well as the -Z' face of a tuning fork crystal vibrator to the tuning fork arm part tip or other parts simultaneoulsy or independently for the purpose of adjusting the oscillation frequency of the crystal vibrator and the temperature characteristic into a prescribed target value and a prescribed value respectively. CONSTITUTION:The evaporation adhesion position and area are so selected that DELTAfT (the change quantity of frequency fT of the torsional vibration mode)/DELTAfF (the change quantity of fF of the bending vibration mode) may be 1. For the purpose of adjusting fF and fT before evaporation adhesion into prescribed points 1 and 5, first, prescribed oscillation frequency 1 is ignored by evaporation-adhering the -Z' face to the tuning fork tip, and fF and fT are adjusted to values shown by points 6 and 7 so that (DELTAfF-DELTAfT) may be a prescribed value. Next, the +Z' face is evaporation-adhered in a proper position with a proper area so that (FF- fT) cannot be changed, that is, DELTAfT/DELTAfF may be 1, thereby adjusting the frequency of the reference vibrator of this composite vibration type crystal vibrator into a frequency as a prescribed standard oscillation source.
