ABSTRACT:
A method for stabilizing the vibration frequency of an oscillator which contains a tuning fork-type quartz crystal element comprising a pair of arms each having a given size and a common connecting section connecting the mutually facing ends of the paired arms. The method comprises bonding the common connecting section of the quartz crystal element directly to a base member supporting the same by an appropriate adhesive agent, sensing the amount of vibration energy leaking from the crystal element into the base member while causing the paired crystal arms to be mechanically vibrated in the opposite directions, and minimizing the leaking vibration energy by repeatedly adjusting each size of the paired crystal arms, thereby enabling the subject quartz crystal oscillator not only to minimize the amount of vibration energy leaking to the outside therefrom but also present excellent resistance to external mechanical vibrations and shocks, and consequently maintaining the vibration frequency of the crystal oscillator at the highest possible precision and stability for a long period of time.
