Abstract: Disclosed is a fiber for artificial hairs that is given a predetermined shape, the fiber being formed from a synthetic fibroin fiber containing a modified fibroin, and the fiber expanding when placed in a wet state and contracting when dried from a wet state. Also disclosed is a method for producing a fiber for artificial hairs that is given a predetermined shape, the method including retaining a fibroin fiber containing a modified fibroin in a state conforming to a predetermined shape. A wetted fibroin fiber may also be heated while being retained in a state conforming to a predetermined shape.

Abstract: A coating composition comprising (A) a thermoplastic resin having a glass transition temperature of 0.degree. to 80.degree. C., (B) a compound having 2 or more hydroxyl groups in the molecule, (C) a thixotropic agent and (D) a solvent, and said coating composition having a viscosity of 3 to 50 poises at 25.degree. C. and a thixotropy of 2 or more can give a moistureproof insulating coating film with uniform and large thickness and very few bubbles by one-time treatment over packing circuit boards.

Abstract: A stabilized absorption composition comprising (a) a halogenated hydrocarbon refrigerant, (b) a liquid absorbent of a polyethylene glycol methyl ether and (c) at least one stabilizer selected from phosphite esters, epoxy compounds and organotin compounds is excellent in stability and can be used for an absorption type refrigerator for a long period of time without causing corrosion.

Abstract: A liquid crystal display element which may have a multi-layer structure comprising substrates having electrodes and liquid crystal orientation controlling films on the sides thereof facing a liquid crystal layer and one or more liquid crystal layers interposed between said substrates, characterized in that the liquid crystal orientation controlling film is made from a copolymer produced by reacting a dibasic acid dihydrazide, a diamine and a tetracarboxylic acid dianhydride, followed by ring closure and dehydration with heating, is excellent in transparency and the electrode (partially reflected) pattern is hardly observable.

Abstract: In a liquid crystal display element having a twisted structure wherein the periphery of two transparent glass substrates having electrodes according to desired display patterns is sealed with a sealing medium and a liquid crystal is enclosed in the space thus produced, the one characterized by having an undercoating film of metal oxide on the inner surface of each glass substrate, having a transparent electrode on each undercoating film of metal oxide and having an orientation controlling film made from an organic polymer and having abrasion grooves along a certain direction on each electrode can give a liquid crystal display element excellent in heat resistance of the orientation controlling film, excellent in adhesion to the glass substrates, and the like without causing a voltage drop, or without damaging rising of voltage-brightness property and response property.
