Abstract: 1,054,331. Semi-conductor devices. HITACHI SEISAKUSHO KABUSHIKI KATSHA. May 14, 1964 [May 16, 1963], No. 20180/64. Heading H1K. A method of producing semi-conductor elements comprises forming at a semi-conductor surface a first layer containing an impurity of one conductivity type, removing selected parts of the first layer by etching, and diffusing an impurity of the opposite conductivity type and having a higher diffusion co-efficient than the first impurity into the surface to form a second layer which underlies the remaining parts of the first layer. As shown, Fig. 1(d), a plurality of transistors are produced by heating a wafer 1 of P-type germanium in an atmosphere of an inert gas containing indium vapour to form a P-type diffused layer 2. Parts of the top surface are masked with wax and the exposed areas of layer 2 removed by chemical etching. Alternatively this may be done by mechanically engraving grooves in the surface. Arsenic is now diffused into the wafer and forms an N- type layer 3 on the exposed parts of the wafer and also beneath the remaining areas of P-type layer 2. The top surface of the wafer is masked, as at 4, and then etched to form a plurality of devices. As shown. Fig. 2, ohmic contacts 5, 6, 7 and leads 8, 9, 10 are joined to the emitter, base and collector regions respectively. Some out diffusion of indium occurs from the surfaces of the emitter during the arsenic diffusion and this reduces the impurity concentration of the emitter where the Junction emerges. The emitter can be of other shapes.

Abstract: 1,091,168. Division mechanisms. MONROE INTERNATIONAL CORPORATION. May 3, 1965 [May 4, 1964], No. 18520/65. Heading G4B. In a calculating machine adapted for division, the divisor, entered into digital actuators 26 (Fig. 9) is subtracted from the dividend register 6 by complemental addition until an overdraft is indicated in the register 6. The divisor is then added once to the dividend before the carriage 27 of the digital actuators 26 is moved one position to the right. Entry of the dividend.-After depression of digit keys 1 (Fig. 1a) to enter a dividend into the storage gears 20 of a selector carriage 2, the gears 20 are lowered into engagement with the racks 18. On depression of a key (16, Fig. 2, not shown) the gear-wheels 25g (Fig. 9) of the dividend register 6 are lowered into engagement with racks 23, reciprocated with racks 18, so that on the return stroke of racks 23 a dividend is entered into the register 6. Entry of the divisor.-After the divisor has been entered into selector carriage 2, a further key (17, Fig. 2, not shown) is depressed so that gear-wheels 28 of the actuator unit 7, lowered into engagement with racks 23, rock teeth 26t of the unidirectional rotary digital actuators 26 into the set position (Fig. 13). Quotient registration.-The carriage 27 (Fig. 9) with actuator unit 7 and counting gear 195 is shifted to the leftmost position with respect to the register 6 so that the counting gear 195 engages the highest order gear 30 of a quotient register 9. The actuator unit 7 is then moved a step to the right so that the non-set teeth of the digital actuators 26 engage with the gears 87 of the dividend register 6 for subtraction of the divisor by complemental addition, a finger 204 rotating the gear 30 additively through one step for each successive subtraction. When a " 9 ", indicating an overdraft, is registered in the highest order gear of the dividend register 6, the actuator unit 7 is moved a step to the left so that the set teeth of the digital actuators engage with the gears 87 to add the divisor once, a finger 203 simultaneously rotating the gear 30 subtractively through one step. The carriage 27 is then shifted one step to the right and the process repeated. When the carriage 27 reaches its right home position, the gears 30 of the quotient register 9 are lowered into engagement with the racks 23 for total taking and printing and then the gear-wheels 25g of the dividend register 6 are lowered for printing of the remainder.

Abstract: 1,143,667. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 9 Dec., 1966 [10 Dec., 1965], No. 55221/66. Heading H4K. In a P.A.B.X. employing cross-bars or reed relay matrices either party to an existing connection can, by signalling to the feedbridge to which and from which originating and terminating parts of the connection are set up, cause both parties to be connected to a conference circuit, the former connection via the feedbridge being released. A third party is called up and added to the conference by dialling into the conference circuit or alternatively the seizure of a conference circuit and the calling and adding the third party may be made in response to dialling the third party's identity by either party of the two-party connection. In addition a conference circuit may be reacted by a subscriber without first setting up a two-party call. As shown in the Figure, a feedbridge JVS upon receiving a conference request signal-an earth pulse applied by a special substation keyinforms a conference control KOST which receives the identity from identifier JdE of the two parties of the connection set up via the feedbridge JVS and controls a marker M to establish connections between a free conference circuit KOUe and each party over switches KA, KB, KC and KD. The former two-party connection is then released. A register KORg is taken into use by the conference circuit and the identity of the third party dialled with it, to whom a connection is then made. Failure of the third party to reply after a given period of ringing automatically causes the connection to the third party to be released or, alternatively, release may be instigated by one of the two existing confercees dialling the identity of the third party again. To add further conferees, the register must be reseized for each one by sending the conference request signal. Each conference input becomes available again upon a conferee hanging up. If the conference controller KOSt has its own digit receiving facility or has direct access to the exchange receivers the conference circuit is seized and a connection to a third party set up in response to the dialling of the identity of the wanted third party. Particular conference circuits can be seized by sending particular conference request signals.
