Abstract

PURPOSE:To establish the diapason type oscillator having excellent frequency versus temperature characteristics, by using different heat treatment conditions for the both arms of elasticity of the diapason type oscillator attaching the piezoelectric material to the diapason type oscillation piece consisting of constant elastic material. CONSTITUTION:The diapason type oscillator piece 1 made of elinver is attached with the ZnO piezoelectric thin film 2, and the electrode 3 made of gold or silver is formed and the elinver 1 and the electrode 3 are used as one set of electrodes. The frequency versus temperature characteristics of this oscillator manufactured under a given condition is shown in the straight line a with negative slope, but when only one arm 4 of the diapason is heated with laser or infrared ray 6, the arm 4 shows the frequency versus temperature characteristics b of straight line with positive slope. Accordingly, the frequency versus temperature characteristics of the oscillator after one arm is heated, is an excellent straight line as the synthesis of the both characteristics a and b having almost zero slope.
