Abstract

PURPOSE:To adjust the frequency of twist oscillation, by attaching a weight near the center toward lengthwise direction of the tuning fork arm and to >=1 another positions. CONSTITUTION:Tuning fork arm tips 152, 152' of a tuning fork type quartz oscillator 151 and parts 155, 153 around the center lengthwise direction of the tuning fork arm are added with a weight. To adjust the frequency, first a weight (Au) is vapor deposited on the tuning fork arm tips 152, 152' and the frequency of twist oscillation is set to an objective value. In this case, the frequency of a bending oscillation is also decreased, but the dispersion of frequency at the manufacture of the oscillator can be kept constant. Next, the weight (Au) is vapor deposited around the parts 153, 153' at the center lengthwise and the frequency of the bending oscillation is set to an objective value. Since the frequency of twist oscillation is not changed at the frequency adjustment of the bending oscillation, each dispersion can be zeroed.
