ABSTRACT:
A tuning fork type quartz crystal vibrator has electrodes formed on its surfaces with the electrodes being divided into separated portions along the length of the tuning fork arms such that opposite electric fields and charges are juxtaposed in the same arm. Dividing the electrode at a location along the tuning fork arms where strains induced during vibration reverse direction, enhances the ability to induce vibrations. A low resonant resistance and high capacity ratio are provided for an overtone frequency of flexual vibrations.
