Abstract

PURPOSE:As for the piezoelectric flection oscillator, the electrode is arranged by providing stages on the surface of quartz crystal piezoelectric material. As a result, the crystal impedance can be lowered, and a high-efficiency oscillator can be secured with electric field distribution which is near that obtained when electrode is attached to the side surface.
