Patent GB-2188471-A (GB)
Title: L C D devices
Inventor: TAKEDA MAKOTO
IPC: G09G3/36
Filed: 1987-03-19
Abstract: A matrix-type liquid crystal display device comprises a plurality of switching transistors and display picture-element electrodes on respective crossing points of signal electrodes and scanning electrodes on a first substrate; a second substrate mounting counter electrodes, a system for causing the polarity of signal to be delivered to signal electrodes, to be inverted for a specific period corresponding to an integer multiple of one scanning period that makes up the minimum unit; and a system for synchronously feeding the polarity-inversion signals to the opposite electrodes using a specific timing exactly identical to that of the above signal electrodes. In particular, the device related to the invention allows the proportion of the period of polarity inversion of the counter electrode signal against one scanning period to remain almost constant, independent of the timing of scanning signals, and as a result, the device related to the invention generates uniform display contrast effect over the entire image screen, even though stray capacitance of respective picture elements is substantially greater than the capacity of liquid crystals.

Abstract: A process of forming a coherent refractory mass on a surface comprises projecting against that surface, together with oxygen, a mixture of refractory particles and fuel which reacts in an exothermic manner with the projected oxygen to release sufficient heat to melt at least the surfaces of the refractory particles and thus form the refractory mass. The projected mixture contains, as fuel, finely divided particles of at least one element which is oxidisable to form a refractory oxide and it also contains carbonaceous particles which are of such a size or composition that carbon particles become occluded in the formed refractory mass. The mixture may contain, as said fuel, finely divided particles having a mean grain size of less than 50 mu m of silicon, aluminium and/or magnesium. The carbonaceous particles may comprise a carbonaceous core which is covered by a mantle inhibiting oxidation of the core. The mixture may further contain particles comprising a core of at least one element which is oxidisable to form a refractory oxide which is covered by a mantle inhibiting oxidation of the core. Suitable mantle materials include metallic oxides, nitrides and carbides.

Abstract: For acting as a back-up for an excess voltage arrestor that has one terminal connected to a stud terminal (1) and another terminal connected to ground an air gap arrangement (10) is provided as part of an assembly that includes the terminal (1). In a particular embodiment, the air gap arrangement (10) includes a flanged sleeve (14) of insulating material mounted on the terminal (1) and having mounted en it a first conductive washer (15A) in electrical contact with the terminal (1), a second conductive washer (15B) held out of electrical contact with the terminal (1) but in contact with a grounded connector tag (17), and an insulating washer (16) sandwiched between the first and second washers (15A, 15B). The aperture in the insulating washer (16) is over-size as compared with the sleeve (14) so that there is an air gap (20) between the first and second conductive washers (15A, 15B). Current flow is normally from the stud terminal (1) to the excess voltage arrestor. In use, should the arrestor fail to operate to protect against excess voltage, discharge to ground takes place across the air gap arrangement. <IMAGE>

IPC: B29C65/78
Filed: 1989-10-20
Abstract: A leading one of a succession of articles 1 is brought along a feed path 2, to a predetermined position at which the leading edge of article 1 defines a datum position 7. The leading end 5A of a strip or elongate material 3 is also brought, from a supply 4 thereof, to position 7. The article 1 and strip 3 are fed together along common feed path 2 to a sealing device 13 until perforations made on strip 3 by a perforator 10 align with position 7. The strip 3 is clamped by means 12 between points B and C so that strip 3 separates at the perforations from the rest while being pulled by the feeding thereof. A new leading edge of strip 3 is thereby produced at position 7 and the clamp 12 is released and the cycle repeated. The device 13 incorporates means for feeding strip 3 and article (container) combination 15 through device 13 at such a rate that strip 3 is heated sufficiently to activate heat responsive adhesive applied to strip 3 and incorporates pressing means. <IMAGE>
