Abstract: A molding material for thermoplastic composites is provided. The molding material is prepared from a commingled yarn containing continuous thermoplastic fibers and continuous reinforcing fibers, in a form of threads, textile fabrics, knitted fabrics, or multiaxial laminated fabrics, wherein the fiber commingling parameter of said continuous reinforcing fibers in said commingled yarn is 20% or more, and wherein the orientation index after heat treatment of said continuous thermoplastic fibers is 0.3 or more, and/or the thermal shrinkage ratio of said continuous thermoplastic fibers is 15% or less.

Abstract: A liquid crystal light shutter having means for stabilizing molecular orientation of a liquid crystal material is provided. In one embodiment of the invention, isolation electrodes are provided parallel to and between adjacent common electrodes on a substrate. In an alternate embodiment, the effective gap distance between adjacent common electrodes is at least ten times greater than the distance between opposing substrates.

Abstract: A multi-layer member of corrugated board made of active carbon fibers having an equilibrium adsorption amount of benzene of not less than 200 mg/g and a benzene adsorption rate constant of not less than 0.2 min.sup.-1.

Abstract: A method for adsorbing harmful substance comprising at least two adsorptive units composed of a plurality of cylindrical or bag-shaped adsorptive elements made of a cloth-like or sheet-like adsorptive material having a 0.1 m/second pressure loss of not more than 15 mm Aq/cm, said adsorptive material consisting predominantly of active carbon fibers having an equilibrated adsorption amount of benzene of not less than 300 mg/g and an adsorption rate constant of benzene of not less than 0.2 /minute, and the ratio of the area of said adsorptive material to the area of the unit frame being not less than 2, and at any one of said adsorptive units, when used for desorbing the adsorbed harmful substances, a heated purging gas jetting device being provided at the upper part of the adsorptive unit.
