CONTOUR SHEAR CRYSTAL RESONATOR

摘要

PURPOSE:To realize a crystal resonator excellent in the linearity in the frequency temperature characteristic by selecting optimizingly a cut-angle of a contour shear crystal resonator. CONSTITUTION:An exciting electrode 2 is arranged at upper and lower faces of diaphragm 5 of a crystal 1 and the resonator is excited by the electrode 2. The diaphragm 5 of the crystal 1 is connected to a support 3 via a connection 4 to attain the incorporation. The resonator is formed from a board rotating a Y plate by 46-53 deg. around the X axis. In using the resonator having the cut angle as above, a crystal sensor with excellent linearity in the frequency temperature characteristic is realized.
