Abstract: 1,232,946. Semi-conductor circuits. MULLARD Ltd. 6 Feb., 1970, No.5808/70. Heading H1K. An integrated semi-conductor circuit (Fig. 1) comprises N-type islands 1, 2 in an epitaxial N-layer 3 on a P-type substrate 4, defined by P-type regions 5, 6, 7 formed by diffusion as isolation walls extending to the substrate. Bipolar transistors are formed in islands 1, 2 by impurity diffusion into their surfaces through openings of a surface masking layer (not shown) and the N-type material forms the collector, the base is formed by P-type regions 8, 9 and the emitter by N+ regions 10, 11 within the base regions. Metal surface contact layers are superimposed, and the transistors are isolated by reverse-biasing the P-N junctions between 1, 2 and 4, 5, 6, 7. Feedback exists through the substrate bulk conductance (equivalent to a resistance network) and the collector to substrate capacitances (Fig. 2, not shown), and if one transistor is replaced by two transistors in separate islands (Fig. 3), it exists through the collector to substrate capacitances 26, 27, 28 and the substrate conductance equivalent to a resistance network 29 (Fig. 4, not shown} which is symmetrical when island 20 is positioned symmetrically on the centre line of the integrated circuit. Push-pull operation of transistors 24, 25 develops antiphased collector voltages so that a null voltage appears at the collector of 23 as nodal point. If the circuit is asymmetrical, a nodal point for positioning the transistor from which feedback is to be eliminated is determinable by the Laplaee equation. The circuit (Fig. 6) may comprise a push-pull transistor stage 30, 31 in respective islands 32, 33, and two or more other islands 34, 35 comprise preceding transistor stages 36, 37, separated from the push-pull stage by an isolation diffusion pattern in the substrate. Feedback over collector to substrate capacitances 41 to 44 and the substrate conductance represented by resistance network 40 is eliminated by symmetrically positioning islands 34 at node points of the substrate potential pattern resulting from the feedback signals. Feedback from a second pushpull pair may be removed similarly. The push-pull pair may comprise other circuit elements than transistors, and alternatively feedback can be eliminated by positioning the islands thereof at points of corresponding potential in the substrate pattern.

Abstract: 1,233,019. Making electrical sockets; stamping. HENRY & THOMAS Ltd., and H. F. CULLENDER. 10 Dec., 1969 [23 Dec., 1968], No. 61101/68. Headings B3A and B3Q. [Also in Division H2] A method of making an electrical socket contact comprises forming or providing a tubular member with at least one open end and having at least one lengthwise slot or groove in the tube walls and a circumferential rib or other projection or projections on the external surface of the tube intermediate the length of the slot or groove, and pressing the rib or projection(s) inwardly to deform the tube walls thereby forming an internal throat. The socket member is of brass or other copper alloy and has four lengthwise slots (14), Fig. 1 (not shown). A mandrel 20 is inserted in the tubular portion and a ring die 21 is then forced over the member from its closed end. The mandrel may carry a sleeve which surrounds the mouth of the socket to prevent expansion thereof. The mandrel may have a different diameter from that of the plug pin so that the radius of curvature of the socket at its throat may differ also therefrom. The slots or grooves in the tubular member may be either helical or axial and they may stop short of the socket mouth. A chamfer may be swaged on the inside edge of the mouth using an external support while forcing step 18 into the mouth.

Abstract: 1,233,083. Splitting. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 July, 1969 [8 July, 1967], No. 32166/68. Heading B5E. [Also in Division H1] A semi-conductor wafer is secured to a foil 1 of synthetic resin by electrostatic attraction and is scribed and severed to form a number of segments. The foil 1 is then extended to space the segments apart so as to facilitate inspection and removal thereof, e.g. by a vacuum probe. In the apparatus shown the foil 1 is hermetically sealed to the edge 12 of a housing 15, and is drawn into a chamber 19 and over a plate 29 by vacuum, thereby extending the foil and separating the segments. A lamp arranged above the housing 15 provides the heat necessary to permit stretching. After extension the central part of the foil 1 carrying the spaced segments may be separated from the remainder of the foil. The plate 29 may carry a layer of glue to facilitate manipulation of the separated part of the foil. Initial severing of the scribed wafer is performed by means of a roller which presses the wafer into contact with a resilient pad mounted on a reciprocating support. The method is applicable to the manufacture of transistors or integrated circuits.

Abstract: 1,233,343. Inserting components in circuit boards; angular bending; shearing. USM CORP. 19 Dec., 1969, No. 62133/69. Headings B3A, B3E and B3W. A machine for cutting and forming leads of an electrical component and inserting them in holes in a circuit board, comprises means for feeding the components one-by-one to a lead cutting locality, rotatable cutting wheels 50 co-operating with shear blocks 90 to cut the leads of a component at the cutting locality, and inserting means for thereafter forming the leads and advancing the component to insert its leads through holes in a circuit board. The component to be inserted has its leads cut to length before forming and insertion which takes place on the return stroke of the machine. Hence when beginning operation with the machine, it is necessary to cycle once before insertion commences. Forming and inserting the leads.-A cylinder 28 acting through a rod 30 forces outside formers 44 and a spacer block 46 downwardly until the block abuts a projection 64, so as to bend the component leads downwardly, Fig. 10 (not shown). A cylinder 18 now forces a driver slide 60 downwardly allowing the formers 44 to continue their downward motion, which carries the component down to the board 2. The cylinder 28 is now at the end of its travel and the formers 44 remain stationary while the driver end 66 of the slide 60 forces the component leads through the board, Fig. 12 (not shown). The leads are then clinched by conventional means. Indexing and cutting operations.-These operations are performed on the upward stroke of the slide 60, which at the bottom of its stroke has carried a feed sprocket slide 124 and a bellcrank link slide 116 to the end of their stroke. This allows the ends of a feed pawl 72 to engage a new tooth space in feed sprockets 70 and at the same time a cutter ratchet pawl 112, which engages a ratchet wheel 52, has been rotated backward by a link 114 and bell-crank 110, which rotation includes a degree of overtravel, Fig. 7 (not shown). A lost motion device delays movement of the slides 124, 116 until the driver end 66 is clear of the shear blocks 90. Then the pawl 72 rotates the feed sprockets 70, indexing a new component into position, but the pawl 112 does not move the cutter wheels owing to the overtravel. When the component is in position the pawl 72 leaves the sprockets 70 and the pawl 112 engages the ratchet wheel 52 thereby rotating the cutting wheels 50 to cut the component wires. The cutters are also moved into a position wherein an open space is available to receive the next component from a belt fed down a raceway 16 to the inserting head. The cutting wheels 50 and shear blocks 90 are independently adjustable to suit the required length of the component leads.

Abstract: 1,250,599. Read-only stores. NATIONAL CASH REGISTER CO. 25 June, 1970 [15 July, 1969], No. 30903/70. Heading G4A. A read-only store comprises a first assembly having an array of semi-conductor elements with current input and output means therefor, and a second assembly (also claimed separately) mounted adjacent thereto and having electrically conductive elements corresponding to selected elements of the array and separated from them by an insulator layer, such that insulated gate field effect transistors are formed at the positions where the conductive elements are provided. In a thin-film embodiment, the first assembly comprises pairs of source and drain electrodes vacuum deposited on a non-conductive substrate, with semi-conductor material vacuum-deposited to connect each source electrode to its corresponding drain electrode. The source electrodes are electrically connected in rows through row switches to ammeters (one per row) and the drain electrodes are connected in columns to column switches. The second assembly is a memory card consisting of an array of interconnected gate electrodes formed by etching on a non-conductive substrate. A dielectric insulator is laminated over these electrodes and contacts the semi-conductor of the first assembly. Selected gate electrodes are removed by punching, etching or optically vaporizing. An MOS embodiment differs by having as the first assembly an N-type semiconductor substrate into which pairs of P-type regions have been diffused, the two regions of each pair being connected respectively to source and drain electrodes deposited, by evaporation and etching, in channels in the substrate. The source and drain electrodes are connected in rows and columns to switches &c. as in the first embodiment, by conductors in channels in the substrate. These electrodes and conductors are insulated from the substrate.

A push-button unit for tape recording and/or playback apparatus comprises a push-button movable to perform a control function, after that as the push-button is moved means produce a perceptible resistance to the movement, and after that the push-button is latched into the operative position. As shown, Fig. 1, when push rod 3 is pushed to the left slider 7 is moved to the left by spring 9 connecting push rod 3 and slider 7. Slider 7 grips switch operating members 6 by means of projections 8 and when slider 7 is moved to the left switch operating members 6 are moved operating contacts 5 in switch units 4. When projections 8 encounter the ends of slots 14 in frame 1 slider 7 cannot move any further to the left and if push rod 3 is released it moves back to the right under the action of spring 2. If push rod 3 is not relaesed but is moved further to the left spring 9 is tensioned thereby offering a perceptible resistance to movement. At the completion of the stroke extension 18 on push rod 3 snaps behind spring loaded catch 17 to hold it in position. If catch 17 is released manually, push rod 3 moves back to the right under the action of spring 2 carrying slider 7 with it. In use the push-button is intended to rewind a tape, for example, the push-rod being depressed until the perceptible resistance is reached and then released when the appropriate spot on the tape is reached, the push rod being latched in for long rewinds. In a second embodiment, Fig. 4, push rod 3 is pivoted and when the push-button is depressed actuates switch unit 4, the push rod then coming up against a brace 21 and spring 20 which provides a perceptible resistance to movement of the push rod, which eventually latches behind catch 17.
