Abstract

676,322. Semi-conductor amplifiers. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. Feb. 7,1950 [Feb. 18, 1949], No. 3134/50. Class 40 (iv). A point contact assembly suitable for a transistor arrangement comprises two resilient contact elements 1 and 2, secured in electrode carriers 14 and 15, and which engage the surface of an element of material 6, which may be a semi-conductor. The element 6 is adjustable so that the surface may be raised, causing the tips of the electrodes to engage the surface at points slightly spaced from each other. The spacing may thus be adjusted to that required between the emitter and collector electrodes of a transistor. To facilitate adjustment and the selection of a suitable point on the semi-conductor surface, the carriers 14, 15 of the point contact electrodes and the electrode 7 which is bonded to the semi-conductor may be slidable and rotatable in their respective mountings. A housing is provided which comprises a window 11 for use when assembling the device.
