摘要:
A moisture-permeable waterproof fabric which has a well-balanced combination of moisture permeability and waterproofing properties and has excellent strength, in particular, tensile strength, is provided without increasing environmental burden. A synthetic-polymer solution comprising a synthetic polymer consisting mainly of a polyurethane, fine inorganic particles, and a polar organic solvent is applied to one surface of a fibrous fabric and then brought into contact with a gaseous phase in which waterdrops having an average particle diameter of 1-30 μm have been evenly dispersed, thereby making the synthetic polymer semisolid. The fabric is then immersed in water to completely solidify the polymer and thereby obtain a moisture-permeable waterproof fabric comprising the fibrous fabric and, united to one surface thereof, a microporous film of a single-layer structure comprising the synthetic polymer consisting mainly of a polyurethane (the number of micropores having a pore diameter of 0.1-5 μm is (5-200)×104/mm2 in a vertical cross-section, and the film has a tensile strength of 3-80 MPa, a moisture permeability as measured by the calcium chloride method of 6,000 g/m2·24 hr or higher or a moisture permeability as measured by the potassium acetate method of 6,000 g/m2·24 hr or higher, and a water pressure resistance of 60 kPa or higher).

摘要:
A part provided with an oil-repellent coating having an oil repellency great enough to enable droplets of fuel and lubricating oil to quickly slide off from the surface in the vicinity of an injection port of a fuel injector and a method of production of the same are provided. A part comprised of a metal base material on the surface of which an oil-repellent coating is provided, said part provided with an oil-repellent coating wherein said oil-repellent coating is constituted by a bottom layer of PES (polyether sulfone) adhered to a surface of the base material and a top layer formed by dispersion of discrete phases of FEP (tetrafluoroethylene-hexafluoropropylene copolymer) in a continuous phase of PES integrally formed with the PES of the bottom layer and wherein the top layer is exposed as the surface of the oil-repellent coating. A weight ratio PES wt %:FEP wt % of PES and PEP which form the oil-repellent coating is preferably 40:60 to 80:20, more preferably 60:40 to 75:25. Preferably, the surface of the base material is roughened so as to raise adhesion with the bottom layer of PES.

A solid coating film (41) is formed on a surface of a screw member (25) of a temperature sensor (1), serving as an internal combustion engine attachment component, by use of a lubricating coating composition containing, as solid ingredients for forming the coating film (41), an organosilicon polymer having a polycarbosilane skeleton cross-linked by a metallic element, and a solid lubricant composed of at least one member selected from among molybdenum disulfide, boron nitride, graphite, and mica, and an organic solvent serving as the solvent for the solid ingredients. By virtue of the coating film (41), high seizure resistance can be attained.

摘要:
Molten metal is prevented from cooling too quickly when supplied to an injection sleeve of a casting device by applying a heat insulating powder onto an inner surface of the injection sleeve between each supply of molten metal. The heat insulating powder can be applied to the inner surface of the injection sleeve by way of an electrostatic field created between an electrode which has been inserted into the injection sleeve and the injection sleeve itself.
