Abstract

PURPOSE:To reduce the effect of the fixed part to increase the Q by specifying the length of the basement after the fork part of the tuning fork type flection crystal oscillator, thus decreasing the deterioration with age. CONSTITUTION:Crystal oscillator 41 features the flection oscillation within the surface of the crystal plate, and the length of the tuning fork basement BC is set to the value through which the node of the flection oscillation is generated at least three areas of points C, D and E each. Thus the displacement can be minimized a the area near support part C to minimize the amount of energy escaping from the support part. As a result, the Q of a high oscillation can be obtained.
