LOOSE COUPLING QUARTZ OSCILLATOR

摘要

PURPOSE:To improve the frequency stability due to the use of an optical system and make the device small in size, by supporting a quartz oscillator having no electrodes on plural narrow wires or rods and sealing them in a vessel. CONSTITUTION:A plano-convex AT cut quartz oscillating element 13a is put on a supporting part 12a consisting of two glass wires and has four corners fixed with an epoxy adhesive and is sealed in a case consisting of a bakelite plate 11a as a part of the case and a part 100a of the case. The quartz oscillating element 13a is driven electrically by an electrode 14a provided apart from the quartz oscillating element 13a.
