IPC: H01L21/00

Abstract: 1,228,699. Doping semi-conductor layers. NATIONAL CASH REGISTER CO. 10 July, 1969 [15 July, 1968], No. 34737/69. Heading H1K. In making a thin film transistor an accurately doped semi-conductor layer is produced by first depositing a thin layer of impurity on an area between and overlapping source and drain electrodes on a substrate and then depositing the layer of semi-conductor in such a way that during deposition the whole of the impurity is incorporated therein. Typically gold source and drain electrodes are vapour deposited at a spacing of 10Á on a glass ceramic or plastics substrate. A measured quantity of copper is next deposited via a mask to a thickness of 2À19 Š on the inter-electrode gap to overlap the electrodes after which a 1Á thick layer of cadmium selenide is deposited. The thus doped layer, which is of high resistivity, is then covered with a 0À1Á layer of silicon monoxide and an aluminium gate electrode layer and copper wires attached to gate, source, and drain electrodes with silver paint. The measured amount of copper is obtained by evaporating a weighed amount through an aperture on to a tantalum strip which is then used as a source in the deposition step proper. Alternative dopants are silver and gold and cadmium sulphide is an alternative semi-conductor material.

Abstract: 1,230,012. Resiliently mounted seats. GREER HYDRAULICS Inc. 29 March, 1968 [5 June, 1967], No. 15337/68. Headings A4J and A4U. In a partially resilient suspension for a vehicle seat having an accumulator 66, with a gas filled bladder 68, in communication with the flotation chamber B of a hydraulic system for adjusting the threshold of the resiliency of the suspension, an independent hydraulic ram 12, 18 is provided for adjusting the height of the seat. In use valve 73 is opened to fill chamber B with oil (so that piston 25 bottoms on plate (36)) and to compress the fixed amount of gas in bladder 68 to the desired extent. Piston 25 is not displaced when the static weight of the occupant is applied to the seat, but it responds to vertical shock loads above a threshold value, determined by the compression of the gas in bladder 68. An apertured disc (52, Figs. 2 and 3, not shown) is movable downwardly into a flowconstricting position, to damp out rapid upward accelerations. Cylinder 12 is pivotally supported at 16, and its inclination can be varied by ram 92.

The condensate may be derived from urea and acetaldehyde, n- or iso-propionaldehyde, n- or iso-butyraldehyde or crotonaldehyde. The reaction may be carried out in an aqueous medium at pH 3-7 and the foaming may be carried out in the presence of a surfactant, e.g. an alkaryl sulphonate.

The four cells are arranged within a hemispherical member 10 having a central boss 25 and four radial barriers (21-24). Member 10 is attached by a bayonet catch 31 to the base which has a common outlet 19 under the boss 25.

The coils have their outer turns connected to the oscillator to reduce capacitative coupling and are all energized in the same sense to reduce inductive coupling. For cleaning, the apparatus is held upside down Fig.4, (not shown) and a detergent germicide is passed in through pipe 19 and impinges on the concave end of boss 25 to be scattered all over the cell surfaces.

Abstract: 1328789 Controlling vehicle headlamps R L MOORE and D G W MACE 3 Nov 1970 [6 Nov 1969] 54521/69 Heading G1A An apparatus for controlling the intensity of vehicle headlamps, which is responsive only to light given out by street lamps supplied by an A.C. power source, comprises a light sensitive means connected to a conversion means providing a signal dependent upon the amplitude of the alternating intensity variations, and control means adapted to control a lamp intensity in dependence upon the amplitude of the intensity variations. In the two embodiments disclosed, control is effected by switching off a dipped headlamp element for the duration of a pulse produced from a monostable multi-vibrator. The frequency of the switching being dependent on the amplitude of said alternating intensity variation. In one embodiment, Fig.1, light is received by a detector 10 whose signal is amplified by an A.C. amplifier 11 (thereby excluding D.C. components due to twilight etc.) A D.C. restoration circuit 12 supplies a peak detector circuit 13 whose output waveform is in proportion to the peaks of the D.C. restored signal. A low level detector 14 (circuit Fig. 2 not shown) provides a D.C. signal which is proportional to the magnitude of the minima in the signal from the peak detector circuit, the signal being subsequently inverted by inverter 19 and fed into a comparator 18. The D.C. restoration circuit 12 also feeds a pulse generator 15 which amplifies the D.C. restored signal and dips it to provide rectangular pulses of constant duration. These pulses are fed to a counter 16 and then by way of a digital-to-analogue converter 17 to the comparator 18. When the output of the inverter equals the output of the digital-toanalogue converter, the comparator activates a gate 20 allowing a pulse from a generator 15 to pass to a switching circuit 21 which disconnects the dip filaments of headlamps 22, 23 for the duration of that pulse. At the same time the pulse passing through the gate 20 resets the counter 16 by way of a reset circuit 24. A detailed transistor circuit is described with reference to Fig.3 (not shown).

The fabric may be woven, non-woven or knitted, cotton scrim preferably being used. The thermoplastic resin, which may be in the form of a closed cell foam, may be a polyolefin or a copolymer of an olefin, e.g. ethylene, propylene or butylene or a mixture thereof, with 2-17% by weight of vinyl or allyl chloride or alcohol, acrylamide, vinyl acetate, ethyl acrylate, allyl methacrylate or methyl methaorylate, or a blend thereof. The molten foamable thermoplastic resin layer may be extruded through a slit die into the nip between a pair of rollers whilst the fabric is simultaneously fed through the rollers, the roller contacting the molten layer being chilled to solidify the layer and optionally being embossed. Alternatively the fabric may be fed to the cylindrical surface of a single roller and a layer of foamable thermoplastic resin extruded into contact with the fabric on the roller so that the layer foams whilst it is in contact with the moving surface of the fabric. The thermoplastic resin sheet may be bonded to the fabric by means of an adhesive, e.g. polyvinyl acetate, polyurethanes, neoprene, polyesters, polyamides or ethylene/vinyl acetate copolymers. The adhesive may be used as a thin resin film of similar or identical composition to that of the foamed resin sheet which is heat sealed to the fabric before it is passed between the rollers for bonding to the foam layer. The laminates so produced are cut to the appropriate shape for the insole assembly and provided with a heel board, e.g. of cardboard or resin-bonded cellulose fibre board.
