Abstract: [Problem] To realize, by means of a simple structure, a soundproofing material having a soundproofing property equal or superior to that of a conventional one against sound including noise arising from vibration generated by a panel (dash panel) that separates the inside and outside of a vehicle cabin or an automotive component and penetrating into the vehicle cabin, and further to realize an excellent soundproofing property in a method for attaching an automotive component using the soundproofing material. [Solution] An automotive soundproofing material made of a urethane foam material, characterized in that the urethane foam material has a single-layer structure, the urethane foam material is configured to have either a uniform thickness or an increased thickness only in a region where it is needed, and an automotive component can be installed while compressing the urethane foam material.

Abstract: A soundproof cover of a compressor for an air conditioner includes a sound-insulating material body portion (11) that is a rubber or thermoplastic-elastomer molded product with sound-insulating properties having a shape corresponding to an outer shape of a compressor body portion including a compressor leg portion positioned on a lower end side, having a folded portion (12) extending along a height direction of the compressor body portion and covering the compressor body portion by being folded through the folded portion (12), a sound-insulating material head portion (21) that is a rubber or thermoplastic-elastomer molded product with sound-insulating properties having a shape corresponding to an outer shape of a compressor head portion positioned on an upper end side of the compressor body portion and a sound absorbing material provided at least inside the sound-insulating material body portion (11).

Abstract: A panel body (1) according to the present invention includes a cushioning layer (51) that contains a fibrous base material (2A) and a cushioning layer (52) that contains a fibrous base material (2B). The first cushioning layer (51) and the second cushioning layer (52) respectively include heat-joining layers (10 and 12) which contain base materials (2A and 2B) and joining materials having lower melting points than the base materials (2A and 2B), and surface layers (20 and 22) which are bonded to surfaces of the heat-joining layers (10 and 12) and are formed of the base materials (2A and 2B).

Abstract: To provide a soundproof cover of a compressor for an air conditioner having manufacturability and workability while possessing excellent soundproofing performance.

Abstract: The disclosed is a transparent conductive film that includes a matrix and carbon fibrous structures added to the matrix, wherein the carbon fibrous structures comprise carbon fibers, each having an outside diameter of 15-100 nm, and wherein the carbon fibrous structures each comprise a granular part at which two or more carbon fibers are bound to each other, and wherein the granular part is concurrently produced in a growth process for the carbon fibers. When the transparent conductive film is formed at a thickness of 0.1-5 ?m on a glass substrate, it shows a surface resistivity of not more than 1.0×1012?/?, and a total light transmittance of not less than 30%. A coating composition for the conductive transparent film is prepared by using a media mill equipped with beads having an average diameter of 0.05-1.5 mm to disperse the carbon fibrous structures into the liquid resinous composition.

Abstract: A new surface finishing process for stainless steel where beautiful, bright and milky white coloured surface is obtainable even for such grades as high carbon containing 13 chromium steel and high sulfur containing free cutting stainless steel is disclosed. After removing the surface scale, (1) immerse the stainless steel into the 1st treating solution containing nitric acid: 5–40 g/l, hydrofluoric acid: 2–10 g/l and Fe(III) ion: 15–40 g/l for 5–180 sec., then rinse in water, (2) and successesively immerse into the 2nd treating solution containing nitric acid: 120–250 g/l, Fe(III) ion: 15–40 g/l for 30–300 sec., then rinse in water.
