Temperature-compensated piezoelectric oscillator that is adjusted by the adjusting method and the method of the temperature-compensated piezoelectric oscillator

摘要

PROBLEM TO BE SOLVED: To provide a temperature compensated piezoelectric oscillator adjustment method for shortening temperature characteristic measuring time by simplifying an adjusting process and also provide a temperature compensated piezoelectric oscillator adjusted with the same method.;SOLUTION: As an adjusting method of the temperature compensated piezoelectric oscillator 10, a heater resistance 26 includesin a package 30 of the piezoelectric oscillator mounting a vibrator 12 and an IC 14, a plurality of frequencies are measured in the course of the heating process of the temperature compensated piezoelectric oscillator 10, and its temperature characteristic is adjusted by obtaining a temperature coefficient. In this adjusting method, at least one of frequencies is measured after the temperature compensated piezoelectric oscillator 10 is heated with the heater resistance 26, compensated data is generated by conducting compensating calculation of the temperature coefficient from the plurality of measured values of frequencies, and the compensated data is written to a storage part of the temperature compensated piezoelectric oscillator 10.;COPYRIGHT: (C)2010,JPO&INPIT
