摘要： 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.

摘要： In a state in which respective portions of a quartz wafer have been masked by a plurality of kinds of mask layers that have respectively different etching rates, the quartz wafer is subjected to an etching process. Since the etching operation is started earlier at a first portion which is masked by the mask layer having a high etching rate, the amount of etching is increased at the first portion. In contrast, the start of the etching operation is delayed at a second portion which is masked by the mask layer having a low etching rate, and the amount of etching is reduced at the second portion. Thus, it becomes possible to form the quartz wafer into a desired shape.

摘要： A piezoelectric filter element 1 is supported by the periphery of a package body 21 of the surface mounting type such that a pair of input/output oscillating electrodes 11, 12 of the piezoelectric filter element 1 face the package body 21. The package body 21 has a shield electrode 30 which extends along a gap G between the pair of input/output oscillating electrodes 11, 12, which presents a grounding potential, and which is apart away by a predetermined distance from a piezoelectric substrate 10. The shield electrode 30 is formed as extending along the gap G and does not face, in a broad area, the pair of input/output oscillating electrodes 11, 12. This prevents floating capacitance from being generated between the shield electrode 30 and the pair of input/output oscillating electrodes 11, 12. Accordingly, even though the shield electrode 30 is brought to very close to the piezoelectric substrate 10, the shield electrode 30 prevents the pair of input/output oscillating electrodes 11, 12 from being electromagnetically coupled with each other.
