Abstract

PURPOSE:The composite body made by uniting crystal vibrator with mold IC is set into the hole part of the print basic plate of having a little wider hole than this one, and is connected each other; so that, absorbing the stress of generating by the difference of thermal expansion, frequency variation can be made little.
