Abstract

PURPOSE:To obtain relatively excellent frequency temperature characteristics at intermediate frequencies, to facilitate the supporting of an E-shaped piezoelectric oscillator, and to improve the mass-productivity by combining the length longitudinal oscillation move and torsional oscillation mode with each other. CONSTITUTION:On the surfaces of oscillating branches 1, 2 and 3 made of quartz, metallic thin-film electrodes 6 and 7 are stuck by vapor deposition, etc. Metallic films 8 are also stuck at the top of the oscillating plates 1-3 as additional mass for fine frequency adjustment. When a voltage having a frequency equal to the resonance frequency of an oscillator 11 is applied between terminals 9 and 10, the oscillator 11 oscillates in the combined oscillation mode of a primary length longitudinal oscillation mode and a secondary torsional oscillation mode.
