Title: Improvements in or relating to semiconductor devices
IPC: H01L45/00
Filed: 1969-10-28
Abstract: 1293152 Solid-state switches ENERGY CONVERSION DEVICES Inc 28 Oct 1969 [4 Nov 1968 13 March 1969] 52760/69 Heading H1K A solid-state element switchable by a voltage above a threshold from a high to a low resistance state consists of an electrode carrying an insulating layer having a pore, preferably 5-40 Á in diameter, . into which switchable semiconductor material extends, and a further electrode over the pore. At least one of the electrodes must be of amorphous refractory material such as molybdenum, niobium, tantalum, tungsten, molybdenum carbide, vanadium sulphide or other carbide, oxide or sulphide of a refractory metal. Typically, Fig. 4, the electrodes 20, 22 extend in opposite directions from the pore on a glass substrate 23. Insulating layer 14<SP>1</SP> and reinforcing layer 26 are of alumina, and the semi-conductor is one of the amorphous semi-conductors referred to in Specifications 1,070,411 and 1,070,412. Each layer of the device is formed by depositing material overall and reducing to the required form by photoresist and etching steps. In another arrange ment with differently shaped electrodes (Fig. 7, not shown) aluminium contacts are deposited on exposed areas of the electrodes and the reinforcing layer overlies the main insulation. A similar device may be formed on the oxide passivation of a silicon integrated circuit with its lower electrode contacting an aluminum electrode of the circuit via a hole in the passivation. Alternatively, to avoid a current carrying interface with the readily oxidizable aluminium the latter is extended out of the hole and on to the lower electrode In such devices an aluminium track extends on the insulation to electrically contact the upper electrode, which is constructed as in Figs. 8 or 11 (not shown) to form a barrier preventing diffusion of aluminium into the semi-conductor. Improved devices are obtained by subjecting the lower electrode and overlying insulation to ion bombardment in the R.F. sputtering apparatus immediately prior to deposition of the semi-conductor and upper electrode material.

Abstract: 1320742 Synchronizing circuits; multiplex pulse code signalling NIPPON ELECTRIC CO Ltd 13 Nov 1970 [27 Nov 1969] 54237/70 Headings H3A and H4L A frame synchronizing circuit for a PCM communication system comprises a detector 108 for detecting the synchronizing pattern in the input digital data, a frame synchronizing pulse generator 105 responsive to clock pulses from a source 102, a gate 106 producing a pulse indicative of non-coincidence between the detector output and the synchronizing pulse, an arrangement 110, responsive to the non-coincidence pulse for producing an output pulse of a width dependent on the time difference between the detector output and the synchronizing pulse as to inhibit sufficient number of clock pulses for effecting synchronization. In operation, a flipflop 110 is set by the synchronizing pulses is passed via an inhibit gate 106 in the absence of the detector output and reset by the detector output applied via a delay circuit 111. The delay D3 introduced by circuit 111 is made equal to the sum of the delay D1 introduced by gate 106 plus the setting time D2 of flip-flop 110. A further delay provided by circuit 107 renders the inhibit pulse and non-coincident with the clock pulse and also enables the output pulse width to be an integral multiple of the clock pulse period.

Title: Method of securing metal mountings on wooden members and apparatus  for carrying out such method
IPC: B27M3/00
Filed: 1971-11-24
Abstract: 1356477 Riveting NILSSONS INDUSTRIEMBALLAGE AB 24 Nov 1971 [25 Nov 1970] 54526/71 Heading B3U Metal mountings 12 having pre-bored rivet holes are riveted to wooden members 8 by feeding the members sequentially on a conveyer 6 to a drilling and rivet inserting station 14, placing the mountings over rivets inserted in members at the station 14, and upsetting the rivets at a riveting station 40. In operation the boards are fed from a stack 10 by the conveyer 6 so that arrival of a board at the station 14 stops the movement of the conveyer. The board is then clamped by a clamp 34 so that rivet holes can be drilled using drills 18. On completion of the drilling rivets 24, in a horizontal guide (not shown) in box 26, are pushed horizontally by pneumatically operated pushers until a rivet passes down each of tubes 28. A cylinder 30 is then actuated so that, via piston rod 32, punches are moved downwardly within the tubes 28 to press the rivets into the board. The conveyer is restarted whereupon the board is turned through 180 degrees so that a mounting 12 can be placed over the rivets at either end of the board. The board then passes to the riveting station where movable plate electrodes 44 are pressed downwards against the ends of the rivets 24, while the rivet heads are supported by plate electrodes 42. The riveting in position of the mountings 12 is thus achieved. In other embodiments the plate electrodes 42, 44 may be replaced either by individual electrodes mounted on a carriage movable in the direction of movement of the conveyer (Fig. 3) or by disc shaped electrodes (Fig. 4). A powder may be sprayed onto the rivet heads to form a protective layer, the powder being melted by the heat of the rivets obtained during the riveting operation.

Title: Improvements in Radars with Provision for Automatic Range Tracking
IPC: G01S13/70
Filed: 1967-11-30
Abstract: 1,199,644. Pulse radar. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. 30 Nov., 1967 [6 Dec., 1966], No. 54684/67. Heading H4D. A device, enabling a range-tracking radar to be automatically supplied with the correctlytimed strobe, is placed ahead of the integration stages 9, 11, Fig. 1, in the range-tracking loop and is effective when the radial acceleration of the tracked target exceeds a predetermined magnitude, the device including two identical and adjustable timed switches 34, 35, Fig. 4, each fed with a pulse train of instantaneous frequency proportional to the acceleration of the error signal from time discriminator 4 and each comprising a normally-closed switch which is opened by a control circuit on reception of the first pulse of the train and is closed on return of the control circuit to its initial state by either a pre-adjusted delay circuit triggered by that first pulse or by a reset circuit acting before the pre-adjusted delay has elapsed. The invention enables range-tracking to continue when two targets are at about the same range (and azimuth). In an embodiment the tracking acceleration error signal #r from amplifier 7, Fig. 1, is converted to a pulse train of frequency proportional to the absolute value of #r in a converter 31, Fig. 4, an acceleration pulse train is fed on line 32 to a switch 34, and a deceleration pulse train is fed on line 33 to switch 35. Each switch may consist, Fig. 2, of an input pulse train terminal 21 and an output terminal 22, pulses being removed from the input train by an opened contact 23 controlled by a relay 24; contact 23 is open when trigger circuit 25 is in the "1" position (i.e. "set") and is closed by a pulse to the "reset" terminal R; initially, contact 23 is closed, the first ensuing input pulse sets trigger 25 to open contact 23 which is closed once again by a pulse delayed by variabledelay circuit 26. Thus pulses which follow an output pulse by an interval less than that of the delay in circuit 26 are eliminated from the output. A signal at terminal 29 provides for re-setting of trigger 25 before the end of the delay of circuit 26. The delay is controlled such that when switch 35 or 36 has passed a pulse the switch opens for a time proportional to actual/predetermined acceleration; the delay may also be proportional to target range to allow for a manoevring target.
