Abstract: The invention provides a novel and improved photosensitive or photocurable composition useful as a photoresist material in the manufacturing process of semiconductor devices such as LSIs by the lithographic process involving etching, in particular, with low temperature plasma in a dry process. The photoresist layer formed of the inventive composition is highly resistant against damages even by direct contacting with a photomask used in the pattern-wise exposure of the photoresist to light owing to the improved pliability thereof and good adhesion to the substrate surface in addition to the stability against the attack by the plasma. The composition comprises (a) a phenolic polymer, e.g. a novolac resin or a polymer of a hydroxystyrene, (b) an aromatic azide compound and (c) a polymer of a vinyl alkyl ether, the amounts of the compounds (b) and (c) being limited relative to the amount of the component (a).

Abstract: The invention provides an improvement over the conventional positive-working photoresist compositions comprising a novolac resin and an ester compound between 2,3,4-trihydroxybenzophenone and naphthoquinone-1,2-diazido-5-sulfonic acid in respect of scum formation in development and resistance of the patterned photoresist layer against heat and dry etching. The inventive composition comprises, in addition to the novolac resin and the ester compounds, 2,3,4-trihydroxybenzophenone in a specified amount relative to the ester compounds as a part of the photosensitive component which may be a reaction product obtained by the esterification reaction for the synthesis of the ester compounds containing unesterified 2,3,4-trihydroxybenzophenone.

Abstract: The inventive organopolysiloxane composition is curable in two ways, firstly, by the irradiation with ultraviolet light and, secondly, by exposure to a moisture-containing atmospheric air. The principal ingredient of the composition is a diorganopolysiloxane having, in a molecule, at least one isopropenyloxysilyl-substituted ethyl or propyl group bonded to the silicon atom of the polysiloxane chain, which is compounded with a mercaptoalkyl-containing organopolysiloxane, a photosensitizer and, optionally, a curing catalyst for the dealcoholation condensation reaction of the silicon-bonded alkoxy groups under the influence of atmospheric moisture. The composition is advantageous in the improved workability by virtue of the adequate tack-free time or the time taken for surface filming.

Abstract: The essential components in the inventive room temperature-curable organopolysiloxane composition are: (A-1) a diorganopolysiloxane of which each terminal silicon atom has a silanolic hydroxy group or two alkoxy groups; (A-2) a filler; (A-3) an alkenyloxy silane, e.g. methyl tri)isopropenyloxy)silane; (A-4) a guanidino-containing organosilicon compound, e.g. 3-(tetramethylguanidino)propyl trimethoxy silane; (A-5) an alcohol, e.g. methyl or ethyl alcohol; (B) an organosilicon compound having a silicon-bonded hydrogen atom; and (C) an organic tin compound as a catalyst. By virtue of the unique formulation above, the composition is very stable in storage in a moisture-free condition for a long period of time without losing the high curability when exposed to a moisture-containing atmosphere.

Abstract: The invention provides an improved stall house for livestock or, in particular, pig breeding in which the excrements from the animals can be disposed under very sanitary conditions with great labor saving. The inventive stall house comprises an array of pens with the floor formed of slatted boards through which the excrements can freely fall down on to the sawdust bed below in an underfloor excrement-receiving vessel extending from one end to the other of the array of pens and a travelling shuffler capable of running in the excrement-receiving vessel back and forth from one end to the other over the sawdust bed with simultaneous shuffling of the sawdust bed to introduce fresh air thereinto in order to promote the aerobic fermentation of the excrements by the aerobic fermentation bacteria in the sawdust.

Abstract: An erasing head for magnetic recording medium by magnetizing said recording medium with a permanent magnet is improved by a ferrite head body having a slider plane wider than a track to be erased, and, a magnetic metal thin film covering said slider plane. Said magnetic thin film solves the problem caused by undesired natural magnetization of a permanent magnet, so as to improve the erase ratio and S/N ratio, and the use of slider plane wider than that of a track simplifies producing process of the head since no step is provided between the track to be erased and neighboring track, and no polishing process for smoothing said step is required.

Abstract: The undercoating composition of the invention, useful for providing an undercoating layer for a top coat of a photosensitive resist layer on a substrate surface, comprises, as a principal ingredient thereof, a condensation product obtained by the condensation reaction between a hydroxy-substituted diphenylamine and a melamine compound substituted on the nitrogen atoms with methylol groups and/or alkoxymethyl groups. The undercoating obtained of the composition is highly resistant against the attack by the overcoating solution applied thereon so that the fidelity of the pattern reproduction by the photolithographic technique is greatly improved by virtue of the absence of any disorder at the interface between the undercoating and top coat layers. The advantage is further increased when the undercoating composition further comprises a photoextinctive agent, e.g. a dye, having absorptivity in the wave length region where the photosensitive resist of the top coat has sensitivity.

Abstract: A magnetic recording medium, comprising a non-magnetic substrate, a magnetic recording layer of ferromagnetic film formed on one side of said substrate, and a topcoat layer comprising an antioxidant and a lubricant and formed on the surface of said magnetic recording layer.

Abstract: In a fire tube boiler, combustion takes place in elongated boiler tubes, which are subject to corrosion, wear, deposition build-up and color changes. A cylindrical camera body, round in cross-section, is inserted into a still-hot boiler tube. The camera body is cooled by cooling fluid and is pushed along the tube using extension rods. A motion picture film strip, preferably color instant film within a cassette, is advanced by remote control, by the operator, to expose a sequence of film frames on the cassette's film plane, as the camera body is progressed within the tube. The tube is dark so that a camera shutter is not used. Instead, tiny light sources, such as incandescent bulbs and/or a swingable mirror, are used to select the exposure time of the film. A fixed-focus and fixed-distance lens system focuses the images from the tube's inner wall on the film plane.

Abstract: The invention provides a novel means for providing a highly heat-resistant and corrosion-resistant coating film on the surface of a substrate such as a semiconductor silicon wafer or glass plate by coating the surface with a liquid coating composition which is a solution of an oligomeric organopolysiloxane as a partial dehydration-condensation product of a monohydrocarbylsilane triol RSi(OH).sub.3, optionally, with admixture of a dihydrocarbylsilane diol R.sub.2 Si(OH).sub.2, R being a monovalent hydrocarbon group, e.g. methyl or phenyl, in an organic solvent followed by baking of the coated substrate to convert the coating layer into a cured resin film.
