Abstract

PURPOSE:To easily provide in one body, to serve as one quartz oscillator and to make it convenient for mounting, by providing two ceramic cases wherein a quartz bar is sealed and fixed back to back putting lead wires between both cases in one body. CONSTITUTION:A quarts bar 6 is fixed to a ceramic case 7, a glass cover 8 is vacuum-sealed with a solder 9, and electrodes on the quartz bar 6 are connected to the electrodes provided to two parts at the rear side of the ceramic case 7 to form a quartz oscillator. Two quartz oscillators with different top frequency temperature are provided back to back, lead wires 12, 13 are fitted on the electrodes and put between the ceramic cases 7, 7 and they are bonded with conductive epoxy adhesives 14, 14, 14, 14 in one body.
