摘要:
A polyurethane dispersion is obtained by aqueously dispersing an aqueous polyurethane resin obtained by reaction of an isocyanate group-terminated urethane prepolymer with a chain extender. The isocyanate group-terminated urethane prepolymer contains an adhesive urethane prepolymer for imparting adhesion and a gas-barrier urethane prepolymer for imparting gas barrier properties.

A harness slack take-up structure for a steering gear enables a harness case to be compact and the harness to be a standard round harness. The harness slack take-up structure employs a movable part and a fixed part to restrict the movement of the slack of the harness somewhat and to take-up the slack, thereby minimizing the size of the harness case.
摘要:
A polyurethane resin having a total concentration of the urethane group and the urea group of not less than 15% by weight is prepared by reacting a diisocyanate component (e.g., an aromatic diisocyanate) with a diol component (e.g., a C2–8alkylene glycol). The repeating unit of the polyurethane resin may contain a constitutive unit of an aromatic or alicyclic compound. The polyurethane resin may be shaped into a film for use as a gas barrier film. The film may be a gas barrier composite film composed of a base film layer and a resin layer at least comprising the polyurethane resin. The present invention provides a polyurethane resin excellent in gas barrier properties against water vapor, oxygen, aromatics, and others, and a film containing the same.

The invention relates to a coating solution for forming transparent conductive tin oxide film, a method for producing transparent conductive tin oxide film, and transparent conductive tin oxide film. The coating solution is capable of forming, from an inexpensive starting material such as tin oxide or tin chloride, strong tin oxide film endowed with excellent conductivity and transparency. The coating solution, which is intended to be used for forming, by way of coating, transparent conductive film predominantly containing tin oxide, contains stannic acid as its major component, and a water-soluble polymer having a polar group which is dissolved in the presence of at least one compound selected from the group consisting of ammonia and water-soluble amines.
摘要:
An electronic apparatus includes a thermally insulated vessel having a cooling part therein. Disposed inside the thermally insulated vessel are a first electronic part and a second electronic part. The second electronic part is spaced apart from the cooling part while the first electronic part is in direct contact with the cooling part, such that the two electronic parts can operate at different cooling temperatures.
