Abstract

PURPOSE:To make a quartz oscillator three terminals and facilitate making it small- size, by connecting electrically one of exciting electrodes for fundamantal wave of the quartz oscillator and one of exciting electrodes for high frequency mutually and by connecting them to the earth. CONSTITUTION:Electrode 6b out of exciting electrodes 6a and 6b for fundamental wave of quartz oscillator 5 and electrode 6d out of exciting electrodes 6c and 6d for high frequency are connected electrically and are connected to the earth. Thus, only three terminals are required for connection between oscillating circuits 7a and 7b and quartz oscillator 5.
