Title: Integrated circuit and method of manufacturing same
IPC: H01L21/00
Filed: 1971-09-28
Abstract: 1336780 Semi-conductor devices THOMSONCSF 28 Sept 1971 [2 Oct 1970] 45246/71 Heading H1K An integrated S/C circuit (Figs. 1, 2) comprises an e.g. N doped Si wafer 1 covered with a layer 2 of Si, O 2  in which are formed a P + doped source region 3 with grounded metal contact 32, a P doped channel 7, and a N+ doped gate region 9 with metal contact 92 extending into a further area to form contact 10 wider than the plate, deposited on an exposed substrate zone 101 and overlapping the oxide layer. A P+ doped region 4 forms the drain region, with metal contact 42 and further contact 43 connected thereto extending over the oxide; and a P doped region 81 constitutes a load resistor extending from region 4 to a P + doped region 5 which with an inlet contact 52 forms a negative D.C. supply input. A substrate zone 111 overlapping the oxide layer with metal contact 11 overlying the oxide layer is connected to bias source, and the substrate between zones 101, 111 constitutes a bias resistor Rp; and an elementary amplifier circuit is thus formed (Fig. 3, not shown). In manufacture, the oxide layer is formed by cathode sputtering or wet thermal oxidation, and the necessary windows therein are etched through a resin mask apertured electronically by the modulated beam of an electron microscope under analogue or digital control of the mask configuration. P-Regions 3, 4, 5, 7, 8 are formed by ionic implantation of e.g. Bo; the regions 3, 4, 5 having a high P + concentration and regions 7, 8 having a lower P - concentration. The element is then thermally annealed, and oxide layer 2 is reconstituted by cathode sputtering in zones 3, 4, 5, 7, Rc. Further windows delimiting zones 9, 101, 111 are etched using an electronically apertured mask, and P doping is ionically implanted to obtain gate region 9 and the ohmic substrate contacts 101, 111 delimiting Rp. After further annealing, windows to zones 3, 4, 5 are etched through an electronically apertured mask to expose the substrate, Al is vapour deposited, and further electronic masking and etching delimits the integrated circuit connections and contacts while preserving regions 3, 32, 4, 5, 9, 52, 101 and 111. Schottky gates may be used instead of implanted gates, and the substrate may be other than Si. Individual components are isolated initially by the substrate.

Title: Improvements in or relating to cermets
Inventor: GITTUS JOHN HENRY
IPC: G21C3/64
Filed: 1962-11-30
Abstract: <PICT:1031678/C6-C7/1> <PICT:1031678/C6-C7/2> A cermet having particles of ceramic material dispersed in a continuous metal matrix is made by placing in a die alternate layers of ceramic particles, one particle in depth, and layers of metal matrix material and subsequently pressing the contents of the die to form a compact which is then sintered at an elevated temperature.  In one embodiment (Fig. 2), a nuclear fuel cermet is made by rolling VO2 particles 1 in an adhesive such as resin and then in stainless steel powder so as to produce a coating 3 of the latter, alternate layers of the coated particles and thin stainless steel sheets 4 being placed in a die 5 and pressed to form a compact which is sintered at 1000 DEG C., and then hot rolled at 1000 DEG to 1200 DEG C.  Each of the layers of coated particles may be covered by a layer of stainless steel powder after being placed in the die and before being covered by the next stainless steel strip in the assembly.  Alternatively (Fig. 7), UO2 particles 1 are dropped on to strips 3, of a combustible material such as cellulose or of stainless steel, coated with a layer 4 of adhesive such as sulphur-free rubber solution, the particle coated strips 3 being placed in a die 5 alternately with layers of stainless steel powder 6. The contents of the die 5 are cold compacted under pressure to form a compact which is sintered at 1000 DEG C. and then hot rolled at 1000 DEG  to 1200 DEG C.  The hot rolling is carried out in directions parallel to the layers of particles, e.g. in the direction of the arrow Y and at right angles to this direction and in the same plane, to draw the particles apart which in the finished product are separated by stainless steel.  In order to obtain a desired degree of separation and a desired patter of distribution of the particles, each strip 3 may (Fig. 4, not shown) be coated with discrete spots 7 of adhesive so that when loose particles 1 are dropped on to such a strip, one particle 1 will adhere to each spot 7.  In alternative methods of coating the strips 3 with ceramic fissile particles the strips 3 are coated with particles 1 in parallel lines either by first coating the strips with parallel lines 8 of adhesive (Fig. 5, not shown) and then shaking particles 1 on to the strips, or by transversely corrugating adhesive coated strips 3 (Fig. 6, not shown), shaking particles 1 on to the strips, and subsequently removing the corrugations by applying longitudinal tension or by rolling the strips.  The compacts formed from such strips are hot rolled only in a direction parallel to the lines of particles.  In any of the above methods, the particles may be coated with stainless steel powder and these particles may be dropped through a plasma flame to fuse the powder coatings into solid metal coatings.

Abstract: 1,108,267. Directing vehicle lamps for steering. ROTADIPPER Ltd. 25 Oct., 1965 [6 Nov., 1964], No. 45437/64. Heading F4R. A headlamp or spotlight is mounted on a support carried by a mounting member secured to the vehicle, a linkage being provided between the support and the steering mechanism so that the former is rotated relative to the mounting member in response to movements of the steering mechanism, to produce a rotation of the lamp and simultaneous dipping of the lamp, the linkage being such that it cannot transmit a force in excess of a predetermined value so as to prevent locking of the steering mechanism should the member moving the lamp jam. In one form. the linkage may include a rod slidable in a tube and normally held by a griping device which yields when the pull exceeds a predetermined value. In the form shown, the lamp is mounted on a cap 101 carrying cam followers 109, 109<SP>1</SP> engaging cams 110 carried by a tube 104. The cap is pivoted on a tube 103 rotatable within the tube 104. A freely rotatable pulley 130 may be coupled to the tube 103 by a pivoted lever 133 operated by a cable controlled by the driver. The pulley is connected by a cable with a pulley moved by a lever on the vehicle track rod for moving the lamp in response to the steering, the pulley having releasing devices operating when the torque is excessive. Switching contacts operated by the movement of the pulley 130 may be provided so that the lamp is switched on when the steering is turned through a predetermined angle. Switches may also be provided for enabling the driver to operate the lamp continuously, for switching from a filament giving a narrow beam to one giving a wide beam when the steering mechanism is turned through a given angle, for dipping the vehicle headlamps in response to the turning of the steering mechanism and for extinguishing the lamp when the vehicle is put into reverse.

Title: Tractor having a three-point linkage
IPC: A01B63/11
Filed: 1973-07-28
Abstract: 1438028 Tractor-implement weight transfer DEERE & CO 28 Sept 1973 [29 Sept 1972] 45572/73 Heading A1P Weight transfer between a tractor 10, Fig. 1, and, e.g. a disc harrow 80, is effected by a linkage comprising an inverted U-shaped frame 52 which has its legs 54, Fig. 3 pivoted to the lower draught links 32 of the tractor's three point hitch system and which has a swivel bracket 100 pivotal about and movable along it. The bracket 100 pivotally supports both the tractor's upper link 58 and a weight transfer bar 92 which is connected to the harrow. Either the bar 92 or the link 58 may be a piston and cylinder whereby the U-shaped frame 52 may be rocked. As shown the link 8 is a piston and cylinder and retraction of the piston rod causes bar 92 to exert an upward force on the harrow and transfer weight to the tractor. The pivoting of the U-shaped frame 52 by the hydraulic link 58 may be controlled manually, or automatically in response to draught load. If control is automatic the tractor may have a draught responsive, horizontal A-frame 42, Fig. 1, fitted beneath its frame 12. The A-frame can be acted upon by either (a) the lower draught sensing links 32 (as shown) if the harrow's draw bar 86 is connected to the links 32 via a cross bar 92 positioned within draught link hooks 34 (in this case the weight transfer bar 92 is connected to the harrow's drawbar 86); or (b) by the harrow's drawbar 86 if it is connected not to the links 32 but to the tractor's drawbar 120 (which will particularly be the case when the harrow is connected to the tractor's p.t.o. shaft (112), Fig. 6 (not shown)). The tractor's drawbar 120 can be fixed or laterally pivoted upon a lower frame 128 and influences the A- frame 42 via arms 124 and pins 132 connected to the A-frame, (in this form of control the bar 92 comprises pivoted links and is connected to the harrow frame). The lower draught links 32 are lifted and lowered by arms 46 pivoted to rock shaft 48. The rock shaft 48 and upper link 58 are controlled either manually by on-off hydraulic valves 170, 172 or in responsive to the automatic draught control. In Fig. 7 main control valve 160 is controlled either manually by lever 156 or automatically by draught variation by engagement of an elastic transverse bar 140 of the A-frame 42, Fig. 1 with a signal lever 146. Hydraulic or electrical sensors may replace the elastic bar 140. In a modification of the automatic weight transfer the A-frame 42 is omitted and the extension and retraction of the upper link 58 in response to the draught load is controlled by the pressure on the rearward side of the piston, Fig. 8 (not shown).

Title: Improvements in fuel systems for internal-combustion engines
Inventor: ISLEY WALTER FREDERICK
IPC: F02D19/06
Filed: 1964-11-10
Abstract: 1,087,974. Viscosimeters. CONTINENTAL AVIATION & ENGINEERING CORPORATION. Nov.10, 1964, No.45766/64. Heading G1S. [Also in Division F1] A device measuring the viscosity of a fuel is used to determine the position of a maximum delivery stop of a fuel injection pump of an I. C. engine. Fuel entering at 112 is reduced to constant pressure by a spring-loaded valve 121 and fed through passage 114 and a narrow passage 130 to a chamber 131 from which it flows through an adjustable restriction 135 to pipe 126 leading back to the fuel tank. The flow through passage 130, and hence the pressure in chamber 131, varies in accordance with the fuel viscosity and a pressure responsive device 136 actuates a wedge 139 to adjust the maximum delivery stop of the fuel injection pump, through linkage 140, to obtain constant maximum engine output regardless of the fuel used. The effect of temperature change on the fuel viscosity is compensated for by making the part 116 of a material of relatively high thermal expansion, e.g. zinc, and the surrounding body 113 of low expansion material e. g. cast iron. In Fig.9 (not shown) escape of fuel along the rod (248) is prevented by supplying lubricating oil under pressure to chamber 416.

Title: Method and system for triggering a pulse within a range of adjustment of a drive means
IPC: G06F7/62
Filed: 1974-10-23
Abstract: 1488516 Ignition timing ROBERT BOSCH GmbH 23 Oct 1974 [23 Oct 1973] 45808/74 Heading F1B An ignition timing signal for a known ignition system 46 is produced from a signal from a generator 13 co-operating with a disc 11 rotating with the engine drive-shaft 10 and fed both to a first counter 17, and to a pulse trigger 20, the output of which is fed to a gate circuit 26 where it is added to a gate timing signal 63 so that during the gate time a train of pulses may be fed from a frequency generator 57 to a second counter 32, a comparator 40 comparing the reading of counter 37 and the counting store 32 and signalling a trigger stage 43 for the ignition signal when these readings are equal. As shown, the output of pulse trigger 20 is also fed to the gate timing signal 63 which is temperature adjusted. Similarly the frequency generator 57 may be vacuum adjusted. A limiter stage 54 in a feedback from the counting store 32 limits the maximum content of the counting store 32. At maximum rotational speed, no pulses are fed from frequency generator 57 to the counting store, a zero identification stage 49 detecting this and feeding the signal from generator 13 to the trigger stage 43 via pulse trigger 20 and itself. A reset stage 70 is actuated also by pulse trigger 21. The disc 11 may be mounted on the cam-shaft or be replaced by a pole wheel for magneto ignition systems. The generator 13 and pulse triggering teeth 12 may be replaced by magnetic plate or photo-electric generator systems. In a combined analog and digital system, the teeth on a wheel (110), Fig. 5 (not shown), act with a first generator (115) to produce the input to a first counter (131), and to produce the input to a second counter (151) limited by a low-pass filter comprising a capacitor (136) and variable resistor (137), and a field effect transistor (141). The second counter (151) forms a counting store (151a) together with a transfer gate (165) and a store (160). The counting store (151a) and the first counter (131) are reset by a signal from a second generator (180) co-operating with a bore (112) in the disc (110).

Magnetic tape cassette apparatus includes selector keys acting via electronic circuitry so that a tape carrying spaced recordings is fast wound until indicating signals recorded on a separate track match the selected number, whereupon normal speed is restored. The apparatus also plays conventional cassettes. A cassette having a recording selection carries lugs 80 to operate a relay 90 to connect a twintrack head to one or more playback amplifiers and to control the electronics, whilst lugs 79, 79<SP>1</SP> rock a lever 75 to shift to toothed locking bar 68 permitting selector keys 64 to be depressed and to move an indicator 96 of which type and side of cassette is in use. Depressing start button 39 shifts a slide 44 carrying the head, a pressure roller 50 pivoted at 47 and a pivot 36<SP>1</SP> for an arm 34 carrying a roller 31 driven by pulleys and belts (Fig. 2, not shown) from the flywheel of capstan 22. The normal speed drive shown includes a spindle 61, driven from the capstan flywheel, engaged with a takeup spool turntable 41. When a key 64 is depressed, an electromagnet (81) is energized to move cords 63, 84 to retract the pressure roller 50, disengage spindle 61 from turntable 41 and engage roller 31 with the turntable 41 to implement fast wind until indication signals S2, picked up by the head, operate the circuitry to release the electromagnet and restore normal drive. During fast wind, the sound transducer is muted by a switch (100) operated by the electromagnet, and the circuitry does not perform a counting operation if the interval between adjacent control signals is outside prescribed limits.
