A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 &#x3bc;m to 200 &#x3bc;m, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/&#xb0; C. or less. Furthermore, it more preferably gives a variation of &#xb1;5% or less in mechanical and optical properties to a thermal history at 200&#xb0; C.

The present invention provides an aluminum composite material having neutron absorbing power that improves the ability to absorb neutrons by increasing the content of B, while also being superior to materials of the prior art in terms of mechanical properties and workability. The aluminum composite material having neutron absorbing power contains in Al or an Al alloy matrix phase B or a B compound having neutron absorbing power in an amount such that the proportion of B is 1.5% by weight or more to 9% by weight or less, and the aluminum composite material has been pressure sintered.

The present invention relates to a sliding member formed of a synthetic resin composed mainly of a polyethylene, said sliding member comprising a molded piece of a polyethylene having a viscosity-average molecular weight of 500,000 to 6,000,000 inclusive, having a low coefficient of friction and excelling in both its own wear resistance and its property of preventing the abrasion of an associated member.

Method of injection molding ultra-high molecular weight polyethylene

An ultra-high-molecular-weight polyethylene sheet characterized in that it is formed into a sheet-like material of 100 to 300 .mu.m in thickness by extruding into a sheet form a feed polyethylene comprising an ultra-high-molecular-weight polyethylene having a viscosity-average molecular weight of 300,000 to 2,000,000.
