Title:
HIGH STABILITY PIEZOELECTRIC OSCILLATOR
Document Type and Number:
Japanese Patent JP2004048686
Kind Code:
A
Abstract:

To obtain a design means for preventing an electronic component or the like to be used for a high stability piezoelectric oscillator from being deteriorated by heat aging when the high temperature side of use temperatures is as high as 85°C.

In the piezoelectric oscillator provided with a first thermostatic chamber storing a piezoelectric vibrator and an electronic oscillating component, a second thermostatic chamber for housing the first thermostatic chamber and a temperature control means for controlling temperatures of the thermostatic chamber for setting the temperature of the first thermostatic chamber lower than the temperature of the second thermostatic chamber, a heat source is arranged near the piezoelectric vibrator.
