Abstract: This invention relates to a reflection liquid crystal display device using a reflection liquid crystal light bulb and a method for fabricating such liquid crystal display devices, and an object thereof is to provide a liquid crystal display device and its manufacture wherein the numerical aperture of the subpixel is increased to improve the display brightness.

Abstract: For the production of a shoe upper by cutting out of the shoe upper in the form of a layout from a web of material, shaping of the shoe upper with connection of material parts of the layout with formation of seams, a process is used by which such shoe uppers can be produced in a timesaving and efficient manner despite the many individual parts present or to be made visible. For this purpose, a web of material (1) is used to produce layouts (2) by different production measures, such as different styles, yarn material, color, material thickness, single layer or multilayer type of material or the like, at the same time with the production of web of material (1), and with a sole part attached to the layout. The layout is cut from the web as a unit with the sole part and processed into a shoe part having an upper and sole part.

Abstract: Polypropylene interior parts for autocars having overcome the drawback of their permanent bulge or secondary deformation due to high temperature exposure is provided, which parts are obtained by molding a material comprising a propylene-ethylene block copolymer prepared by polymerizing propylene at a first stage so that the resulting propylene homopolymer can have a relation between its isotactic pentad ratio (P) and MFR of1.00.gtoreq.P.gtoreq.0.015 log MFR+0.955and can occupy 70 to 95% by weight of the total polymerization quantity, followed by polymerizing ethylene or ethylene and propylene in 30 to 5% by weight of the total polymerization quantity at at least one stage, so as to give an ethylene content occupying 3 to 12% by weight of the total polymerization quantity.

Abstract: A piping assembly suitable for cooling a roller section in a secondary cooling zone of a continuous casting line, the roller section having a number of cast strip guide rollers mounted on a support frame through bearing boxes, wherein the piping system includes cooling water passages provided within the frame of the roller section and cooling water circulating ports formed in the wall of the frame and disconnectibly connected to cooling water passages in the bearing boxes and guide rollers.
