Abstract

PURPOSE:To make the oscillator small in size, by making the thickness as less than 0.5mm, thru the provision of parallel exciting electrode for only front and back surface of the crystal with photo etching and thru the maching of diapason type crystal oscillator not by etching but by machine.
