  • Housing and mount for chip type piezoelectric resonator
    Patent number: 4588918
    Abstract: An improved chip type piezoelectric resonator in which an element having electrode layers formed on main surfaces of a piezoelectric substrate is held in a rubber-like elastic member filled in a through-bore axially formed in a chip-like case having predetermined external dimensions so as to be capable of effecting thickness shear vibration, with a consequent elimination of scattering or deviation in the external dimensions of the piezoelectric resonators.
