Abstract

1,251,675. Semi-conductor force transducers. CONRAC CORP. 15 Oct., 1968, No. 29238/71. Divided out of 1,251,674. Heading H1K. The claims of this specification the subject matter of which has been divided from Specification 48784/68 are directed to formation of a force transducer by placing an annular semi-conductor support member on the edge of a monocrystalline semi-conductor diaphragm and regrowing it thereon by interposing a metal in which the semi-conductor is soluble between support and diaphragm and subjecting the assembly to temperature gradient zone melting, or where the support is monocrystalline by correspondingly regrowing the periphery of the diaphragm on it. With sensors formed in the diaphragm electrically connected and the support clamped the resulting assembly can be used as a force transducer. Further processing leading to formation of pressure transducers are described also in Specification 48784/68.
