Title: Liquid crystal display
IPC: G09G3/18
Filed: 1972-07-21
Abstract: 1394750 Alpha-numeric displays TEXAS INSTRUMENTS Inc 21 July 1972 [2 Aug 1971] 34217/72 Heading G5C A liquid crystal display device comprises a semi-conductor substrate 10 in which a plurality of electrodes are provided, preferably arranged in several figure-of-eight arrays. The device comprises electrodes, terminals 14, leads, liquid crystal material confined by a spacer 18 and a transparent electrode 20 formed by an InO 2  or SnO 2  coating on a glass member 24. The substrate 25 (Fig. 6a), is of Si or Ge and includes an epitaxial layer 27. A transistor comprising a collector 28, base 34 and emitter 36 is formed in the layer 27 and is isolated by a ring 33. An insulating layer 32 of SiO 2  extends over the layer 27 and a metal layer 30 connects an electrode 12a to the collector 28. The transistor forms part of a driving circuit which also includes resistors, diodes, capacitors and IGFET devices mounted on the substrate. In another embodiment, the substrate is of P-type Si having a high resistivity in which the electrodes and leads are formed by diffusing impurities. A Si layer is deposited and thinned by orientation dependent etching leaving a thicker area corresponding to the spacer 18. The substrate is heated to 1200‹ C. causing the impurities to diffuse to the surface in the thinned areas. The etched area may be limited to locations above electrodes. In a device which is scanned the electrodes comprise crossed conductor arrays 80 and diodes are formed on one array at each intersection. P-type conducting strips 80 are formed in a Si substrate 78, a first insulating layer 82 is epitaxially deposited, a further insulating layer 87 of SiO 2  is formed and windows etched therein. Impurities are diffused through the windows to form N-type regions 86 which form the diodes with the strips 80. The windows are filled with liquid crystal material and covered by a crossing conductor array. Alternatively, the SiO 2  can be formed on a Si substrate without layer 82 and N-type Si deposited to fill the windows. Driving circuits may be formed in the other surface of the substrate. Connections between the electrodes and circuit elements may be via conducting paths in the substrate.

Weft yarns 43 are delivered towards the needles of a chain-stitch knitting-machine by a conveyor comprising two endless chains 1<SP>1</SP>, 1<SP>11</SP> one of which carries a series of grippers 16a ... 16c and the other carries a series of hooks 17. The weft yarns are delivered from a reel by yarn guides 66 which are manipulated to cause the yarns to be gripped by the grippers 16 and by additional grippers and cutters 98, 99 which eventually clamp and sever the yarn extendedly between the grippers 16 and the yarn guides 66. Having been engaged by a gripper 16, the yarn extending between that gripper and the guide 66 is then engaged by a pair of fingers 48 and a guide roller 49 on a batten 44 which is traversed by a pair of chains 45 across the width of the conveyor whereby the yarn 43 is extended from the grippers 16 on the one chain 1<SP>1</SP> to engage over the hooks 17 on the other chain 1<SP>11</SP>. Following the gripping and engagement of the extended yarn 43 by the grippers 16 and hooks 17 the chains of the conveyor are advanced to advance the yarns towards the needles and to present a further portion of the conveyor for receiving yarns from the supply. A cutter is positioned adjacent one chain of the conveyor near to the knitting head of the machine to sever the ends of yarns extending around the hooks 17 and a cam engages the grippers 16 to cause them to release their yarns after the yarns have been incorporated in the fabric.

Title: Method for producing highly ductile metallic coated sheet and strip
Inventor: COBURN KENNETH GORDON
IPC: C21D9/52
Filed: 1965-08-13
Abstract: A process for producing a metallic-coated ferrous-base metal strip (e.g. of cold-reduced, rimmed, capped or killed, steel coated with Zn, Zn alloy, Al, Al alloy, terne or Sn) having greatly enhanced drawability comprises the steps of forming a strip of the base metal into an opened coil and decarburizing the base metal to a carbon content of 0.015% or less by weight, thereafter cleaning the surface of the base metal in preparation for coating, the cleaning step comprising heating the base metal to a temperature in the range of between 1350 DEG F. and the A3 critical point of the base metal in a reducing atmosphere and then passing the base metal into a bath of molten coating metal without re-exposing the base metal to air.  The cleaning may include initially heating the strip in an oxidizing furnace to 700 to 900 DEG F. so as to burn oil or grease. Alternatively to this initial heating, the strip may be acid pickled or alkali cleaned.  Thus steel strip may be 1) temper rolled, 2) decarburized in open coil form at between 1100 DEG F. and the A3 critical temperature (e.g. 1300 DEG F. to 1500 DEG F.) in a H2 bearing atmosphere (e.g. dissociated NH3) to which steam is introduced, 3) cooled, 4) temper rolled, 5) heated in the oxidizing furnace, 6) heated in the reducing atmosphere at 1350 DEG F. up to the A3 critical temperature (e.g. 1350 to 1575 DEG F.), 7) cooled in a neutral or reducing atmosphere to the temperature of the coating metal, 8) passed beneath the surface of the molten metal and 9) temper rolled.
