Abstract

736,289. Transistors. GENERAL ELECTRIC CO. Dec. 21, 1953 [Dec. 19, 1952], No. 35522/53. Class 37. [Also in Group XL (c)] In a cascaded transistor amplifier (see Group XL (c)), a multiple transistor is employed comprising a PNP and a NPN germanium transistor in a single block, Fig. 4. The colector 55 of the PNP transistor is formed with a projection which acts as the base of a second transistor of the NPN type, a block of insulation 40 being added to increase the mechanical strength. Specification 728,129 is referred to.
