Abstract

PURPOSE:To regulate the frequency of a tuning fork type crystal vibrator used for electronic watches, etc. at a specified value by providing bidirectivity of increasing and decreasing in the frequency adjusting direction through the combination use of coating of a quick dry type oily ink and laser trimming of trimming electrodes.
