Title: Bilevel ultraviolet resist system for patterning substrates of high reflectivity
Inventor: ONG EDITH TING TING
IPC: G03F7/00
Filed: 1984-01-20
Abstract: A bilevel photoresist system (10) of two organic photoresists, both sensitive to deep ultraviolet (UV) radiation from the same deep UV source (e.g., Xe-Hg) and suitable for use in patterning a substrate of high reflectivity in the deep UV, comprises a top layer of a negative photoresist (e.g., the azide-phenolic resin diazidodiphenyl sulfone mixed into poly (p-vinylphenol)) having a thickness of about 0.5 micron, and a bottom layer of positive photoresist (e.g., polymethyl methacrylate), having a thickness about 1 or 2 microns. The top layer is thus of sufficient thickness to be substantially opaque to the deep UV radiation from the source. The top layer is patterned by projecting the deep UV light to form an image therein which is complementary to the ultimately desired pattern, followed by treating the top layer, with a suitable solvent which attacks and removes the unexposed portions thereof. Then the bottom layer is patterned by directing a collimated (parallel) beam from the deep UV source onto the bottom layer, using the thus patterned top layer as a shadow mask, followed by treating the bottom layer with a suitable solvent which attacks and removes the portions of the bottom layer thus previously exposed to the UV light. Then the thus patterned photoresist layers can be used as a protective mask for etching the top surface of the substrate in accordance with the desired pattern.

Title: Glass fibre reinforced cement products
Inventor: HOARE JOHN KENNETH
IPC: B28B21/06
Filed: 1984-02-13
Abstract: In the manufacture of glass fibre reinforced cement products by casting there is provided a mould core 11 which is covered on the outside with a close fitting layer 22 of sheet plastics material, such as polyethyelene, clamped beneath the core. This assembly is lowered into a mould outer 5, and the reinforced cement mix is then poured into the mould cavity 21 and vibrated. When the mix has cured sufficiently to be self-supporting but whilst it is still green, the core 11 may be removed, leaving the lining or plastics material in place so that the core may be re-used long before the product is fully cured. <IMAGE>

Title: Automatic transmissions
Inventor: NISHIKAWA MASAO
IPC: F16H61/20
Filed: 1984-03-27
Abstract: A creep preventing device for vehicles equipped with an automatic transmission has a starting oil passage (111) connected to an oil pressure source (R) and provided at its intermediate portion with a throttle (75); an engine braking oil passage (126) connected to the oil pressure source and a communicating means interposed between the starting oil passage (111) and the engine braking passage (126), and the working oil passage (29), the communicating means operating in response to the operation of a manual valve (Vm) so as to bring the starting oil passage to communication with the working oil passage at the time of starting and to bring the engine braking oil passage to communication with the working oil passage at the time of engine braking. This ensures that should the creep-preventing valve (Vc), which partially depressurises the first-speed (starting) clutch (C1) when it is energized, stick open, engine braking will still be available with the manual valve (Vm) in position I. The creep-preventing valve is solenoid-operated under electronic controls and may be hydraulically closed. <IMAGE>

Title: Production of Si3N4 and SiC whiskers
Inventor: TANAKA MINORU
IPC: C01B31/36
Filed: 1985-12-04
Abstract: To produce silicon nitride and silicon carbide whiskers, cereal chaff is pre-treated with acid and calcined and is then heated firstly in a nitrogen atmosphere, following which silicon nitride whiskers are removed, and secondly it is heated to a higher temperature in a non-oxidizing atmosphere, following which silicon carbide whiskers are removed, there being an addition of secondary feed material after the removal of the nitride whiskers, which feed material consists of further acid pre-treated calcined chaff and/or flakes of a mixture of silicon, silicon nitride and further silicon containing material with an organic binder. Removal of the nitride and carbide whiskers is achieved by treating in each case with a mixture of water an a hydrophobic organic liquid such as kerosene which mixture is allowed to separate. The final carbide residue can be burned to remove carbon and crushed to recover silicon carbide powder.

Patent GB-2173785-A (GB)
Title: Optical preform fabrication
Inventor: PECKMAN ROBERT
IPC: C03B37/018
Filed: 1986-03-21
Abstract: An arrangement for introducing an auxiliary gaseous medium into the interior of an exhaust tube (11) that is joined to a downstream end of a substrate tube (10) from which a primary gaseous medium carrying glass soot particles during a chemical vapour deposition phase of an optical preform fabrication process emerges into the exhaust tube comprises a gas injection tube (13) which is partly received in the exhaust tube with radial spacing therefrom except at a contact zone and has a free end disposed at the region of merger (14) of the exhaust tube with the substrate tube. The auxiliary gaseous medium flows through the gas injection tube into the merger region for mixing thereat with the emerging flow of the primary gaseous medium. Relative circumferential movement is effected between the contact zone and at least the exhaust tube to release any soot present at the contact zone for entrainment in the mixed flow through the spacing and out of the exhaust tube. The gas injection tube lies at the bottom of the interior of the exhaust tube which rotates during the deposition phase in one sense, while the gas injection tube is being rotated in the opposite sense, so that soot accumulations are scraped off both the internal surface of the exhaust tube and the external surface of the gas injection tube as these surfaces move past the contact zone. <IMAGE>

Title: Actuator caps for pressurised dispensers
Inventor: SMITH BRIAN DOUGLAS
IPC: B65D83/14
Filed: 1986-10-01
Abstract: A one-piece actuator cap has a tamper-evident tear strip (11) extending about three-quarters of the way around its skirt. When in place the skirt prevents the upper part of the cap being depressed but when it is removed it leaves a gap that allows such depression, with the upper part hinging about the web (13) that remains. The strip may be in a frusto-conical transitional portion (3) of the skirt of the cap as this facilitates moulding, the strip being defined between two grooves formed on the inside of this portion without needing retractable cores in the mould. <IMAGE>

Title: Interpolating lines of video signals
Inventor: WESTON MARTIN
IPC: H04N5/44
Filed: 1987-05-11
Abstract: Missing lines of a video signal are interpolated from the signal on three successive fields by deriving low vertical frequency components solely from the central or current field and the higher vertical frequency components partly from the lines of the current field and partly from the lines of two adjacent fields. The total contribution from the current field is unity and the total contribution from each adjacent field is zero. The circuitry for deriving and combining these components comprises an arrangement of delays, adders, subtractors and multipliers Fig. 7. The system can be used to generate the missing lines necessary to derive a sequentially scanned video signal from an interlaced scan video signal. The interpolator has a good performance whether or not there is movement in the video signal. <IMAGE>
