Abstract
PURPOSE:To reduce the equivalent resistance and the dispersion in the temperature characteristics, by satisfying the ratio of the width of the width of oscillating arm, thickness and distance, of the diapason type crystal oscillator in the specified range. CONSTITUTION:Taking the width of the oscillating arm of the diapason type oscillator as w, the distance between the oscillating arms s, and the thickness as t. When measuring the equivalent resistance R1 and the top temperature T0 with different s/t, R1 decreases and saturates with s/t increased, and T0 increases and saturates. On the other hand, R1 and T0 are decreased and the both are saturated simultaneously with changing s/w. Accordingly, to satisfy the both of s/t and s/w, after determining the values of t and w, the greater s value can be selected so that the both of s/t>=1 and s/w>=0.25 can be satisfied. Further, in forming the driving electrode not only on the major plane of the oscillating arm but on the side planes, the effect can be much more increased.
