Abstract: This invention relates to an aqueous thermosetting urethane compound for yarn coating and a method of manufacturing coated yarn using the same, wherein the compound for yarn coating includes an aqueous thermosetting urethane resin and has pores, and specifically includes 100 parts by weight of an aqueous thermosetting urethane resin, 1.5 to 2.5 parts by weight of a thickener, and 6 to 12 parts by weight of a processing lubricant. Particularly, this invention relates to an aqueous thermosetting urethane compound for yarn coating, having pores formed using a foam mixer or a chemical foaming agent, and to a method of manufacturing coated yarn by coating the surface of yarn with the aqueous thermosetting urethane compound.

Abstract: The present invention relates to a method for preparing a hydrocolloid which may be applied to skin, particularly, wounds. The present invention comprises a first step of preparing a pre-polymer having a viscosity of 200 cps˜10,000 cps by mixing an acryl monomer and an ultraviolet initiator and irradiating on the mixture with ultraviolet rays; a second step of preparing a complex by mixing at least an ultraviolet initiator and a high water absorbing substance with the resulting pre-polymer; and a third step of polymerizing the complex with irradiating ultraviolet rays. The thus prepared hydrocolloid of the present invention has an excellent absorbency as well as self-adhesiveness, is not remained as any residue upon removing it from the skin (wound) and has less skin irritation, without employing any tackifier.

Abstract: A gravity control apparatus is provided, in which is controlled through the superconducting coil designed for generating uniform magnetic force. The gravity control apparatus includes a hollow cylindrical low temperature container; a combination of B0 coil and a symmetric and/or asymmetric gradient magnetic field generating coil having a predetermined length and inner and outer radiuses, wherein each of B0 coil and gradient magnetic field generating coil is wound onto a bobbin which is installed to the low temperature container so as to form a superconducting magnet, and the B0 coil has three solenoid coils which are arrayed in three parts with a predetermined spacing so as to generate, from the center of the B0 coil, uniform magnetic field having constant magnetic flux density; and a power unit for supplying operating current to each of coils. Thus, gravity acting on the material disposed in the hollow center of the low temperature container can be compensated with a uniform magnetic force.

Abstract: Disclosed is a composition of resist stripper, which is advantageous in light of excellent strippability for residual resists after etching and ashing processes, and superior corrosion resistance to a metal film or a substrate formed with an inorganic material film. The stripping composition comprises 0.5-25 wt % of an electrolytic material having an equivalent conductivity of 300 &OHgr;−1cm2equiv−1 or higher in 0.001 N aqueous solution at 18° C., 60.0-99.4 wt % of water and 0.1-25.0 wt % of a corrosion inhibitor.

Abstract: Disclosed is a stripping composition for removing resist, comprising 5-50% by weight of at least one product obtained from the reaction of alkyl acetoacetate or acetic acid with fatty acid amine, and 50-95% by weight of a solvent selected from the group consisting of water, an aqueous 25 wt % tetramethyl ammonium hydroxide solution, glycol, and organic polar solvents. The stripping composition is so excellent in terms of stripability as to require only a rinsing process with ultra-pure water without passing through a stripping composition removal process with an air knife and a rinsing process with isopropyl alcohol. Also, with low volatility and toxicity, the composition produces as little pollution of the environment as possible, in addition to not encroaching on metal undercoats and pipe substrates such as O-rings, even without corrosion preventives.

Abstract: A game ball having improved gripability. The game ball includes a bladder and a cover. The cover is positioned over the bladder. The cover has an inner surface and an outer surface. The cover has a first impression pattern formed into, and covering at least a portion of, the outer surface. The first impression pattern forms a plurality of outwardly extending raised surfaces on the outer surface. The cover further has a second impression pattern formed into the raised surfaces of the outer surface. The second impression pattern is configured to improve the gripability of the game ball.
