Abstract: 942,216. Transistors. TELEFUNKEN G.m.b.H. March 22, 1961 [March 26, 1960], No. 10435/61. Heading H1K. In a semi-conductor device a body of semiconductor material comprises four zones extending through its thickness, three of the zones being of one conductivity type and the fourth zone being of the opposite conductivity type, each of the said three zones being separated from the others by parts of the fourth zone. In Fig. 4 a rectangular Ga-doped Ge wafer is coated on both sides with a photo-resist lacquer, and exposed to light through masks and developed, so that, when etched, cavities are formed as shown in both surfaces of the wafer. The remaining lacquer is removed and an N-type characteristic impurity material, e.g. As, is diffused into the wafer until areas 2, 3, 4 beneath the cavities are wholly N-type. The wafer is then lapped to remove the N- type layers from the raised portions 1, 5, 6 on both sides, and given a cleaning etch, thus forming a transistor body as shown in Fig. 2, P-type zone 1, 5, 6 constituting the base region, N-type zones 2, 4 forming the collector region and N-type zone 3 the emitter region. Connection is made with the four zones by contact surfaces 7 ... 10, Fig. 3, of e.g. Ag or Au, printed or otherwise deposited on a ceramic plate comprising diagonal slots between the contact surfaces which also contact external conductors 11 ... 14 which pass through the ceramic plate. The transistor body may be fixed to the ceramic plate by cementing in an oven. To form a PNP transistor, the starting wafer is N-type and acceptor impurity, e.g. Ga, is introduced, or donor impurity is removed, by diffusion. The wafer, which may alternatively comprise Si or an inter-metallic compound, may be of any desired shape, e.g. circular, in which case the zones are preferably sector-shaped and the portions 5, 6 radial. A large crystal may be prepared with a number of sets of zones, being cut up after the diffusion step or the cleaning etch to form separate transistor bodies.

Abstract: 786,290. Diaphragm pumps. SELWOOD, Ltd., W. R. April 5, 1956 [April 16, 1955], No. 11013/55. Class 102(1). In a diaphragm pump, the diaphragm 25, reciprocated by rod 22, is horizontal and forms a flap valve at its periphery with seating 16. On the upward stroke of the rod 22 liquid is drawn through the inlet 14 to the chamber 13 below the diaphragm and liquid above the diaphragm is discharged through outlet 23. On the downstroke of the rod 22 liquid in chamber 13 is transferred between the diaphragm 25 and seating 16 to the chamber 18. The chamber 24, formed as a continuation of the chamber 18 above the outlet 23 is filled with air and acts as a reservoir during pumping. When liquid rises above the outlet 23 it effectively closes the reservoir with respect to the atmosphere and the entrapped air acts as a pressure absorbing means thus improving the steadiness of delivery flow through the outlet 23. In a modification the reservoir may be a separate chamber connected to the chamber 18. The pump may be operated manually or by a motor, mounted on base plate 10, through a crank, cam or eccentric. For safety the diaphragm may be dimensioned to break under a predetermined thrust load or to slip relatively to the piston rod or the piston rod itself may include a telescopic joint which slips at a predetermined load.
