Abstract

PURPOSE: To obtain a flat temperature property by adjusting the peak temperatures of plural vibrators with the assistance of condensers connected to the vibrators in series and obtaining the aimed frequency through the change of frequency division ratio.
CONSTITUTION: Condensers C11, C12 connected to vibrators 3, 4 in series are adjusted to equalize the peak temperatures. As a result, the oscillation circuit shows an ideal flat temperature property. Next, the frequency division ratio of frequency divider 5 is adjusted to enable the obtaining of aimed frequency for the output of frequency divider 5.
