A pyroelectric IR-sensor in which a pyroelectric light receiving element is mounted on a MID substrate or a ceramic substrate having a thermal conductivity less than 0.02 cal/cm.sec..degree.C. Both ends of the pyroelectric light receiving element are supported by the substrate, with the central portion of the pyroelectric light receiving element being spaced from the substrate. Chip parts are mounted on the substrate.

Pyroelectric IR-sensor

A pyroelectric IR-sensor in which a pyroelectric light receiving element is mounted on a MID substrate or a ceramic substrate of which thermal conductivity is less than 0.02 cal/cm.sec..degree. C. in a manner that both end portions of the pyroelectric light receiving element are supported by the substrate with the central portion of the pyloelectric light receiving element being spaced from the substrate, and chip parts are further mounted on the substrate.

Pyroelectric IR-sensor having a low thermal conductive ceramic substrate

A pyroelectric IR-sensor in which a pyroelectric light receiving element is mounted on a MID substrate or a ceramic substrate having a thermal conductivity less than 0.02 cal/cm.multidot.sec.multidot..degree.C. Both ends of the pyroelectric light receiving element are supported by the substrate, with the central portion of the pyroelectric light receiving element being spaced from the substrate. Chip parts are mounted on the substrate.

Pyroelectric IR-sensor with a molded inter connection device substrate

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.
