The present invention relates to a power transmission belt containing a tension member extending in a belt lengthwise direction, an adhesion rubber layer in contact with at least a part of the tension member, a compression rubber layer formed on one surface of the adhesion rubber layer, and a tension rubber layer formed on other surface of the adhesion rubber layer, in which the compression rubber layer is formed of a vulcanized rubber composition containing a rubber component, a polyolefin resin and a reinforcing material, the rubber component contains a chloroprene rubber, and the reinforcing material contains a short fiber.

Transmission belt

To provide a thin metal base circuit board which can be not only installed on a flat portion but also closely attached to a side or bottom surface of a case or to a stepped or curved portion and which is excellent in heat dissipation performance, electrical insulating performance and flexibility; a process for its production; and a hybrid integrated circuit, an LED module and a bright, ultra-long-life LED light source employing it. A metal base circuit board having insulating layers and conductive circuits or metal foils alternately laminated, characterized in that the thickness of each conductive circuit or metal foil is from 5 &#x3bc;m to 450 &#x3bc;m, each insulating layer is made of a cured product of a resin composition comprising an inorganic filler and a thermosetting resin, and the thickness of each insulating layer is from 9 &#x3bc;m to 300 &#x3bc;m; and a hybrid circuit board employing it.

Metal base circuit board, LED, and LED light source unit

To provide a resin composition excellent in conformability to special shapes and in holding power without the need of containing a low molecular softener such as a plasticizer, other than a polysiloxane, and a cured product and a sheet using it. A resin composition characterized by comprising (a) an acrylic rubber, (b) a compound containing at least two mercapto groups per molecule, (c) a compound containing at least two acryloyl and/or methacryloyl groups per molecule, (d) an acrylate and/or methacrylate having a Calkyl group, and (e) acrylic acid or methacrylic acid. The above resin composition which contains a thermally conductive filler. A cured product and sheet using it.

Resin compositions, cured article obtained therefrom, and sheet

A method of making a rubber composition. The method includes the steps of: providing fibers of a desired length; treating the fibers with a treating liquid made up of a nitrile rubber-modified epoxy resin and an alkylphenol&#x2022;formaldehyde resin; and dispersing the treated fibers in rubber.

Rubber composition, a method of making the rubber composition, a power transmission belt made from the rubber composition and a method of making the power transmission belt

A method of bonding an ethylene&bull;&agr;-olefin rubber composition with a fiber material. The method includes the steps of adhesion treating the fiber material with a resorcinol-formalin-rubber latex with an ethylene&bull;&agr;-olefin elastomer latex and vulcanization bonding the adhesion-treated fiber material together with an unvulcanized ethylene&bull;&agr;-olefin rubber composition.

Method of bonding an ethylene&bull;&agr;-olefin rubber composition and a fiber and a power transmission belt made using the method

A power transmission belt having a body with a length, an inside, an outside, and laterally oppositely facing side surfaces. The body has a) a cushion rubber layer in which at least one load carrying element is embedded so that the at least one load carrying element extends lengthwise relative to the body, and b) a compression rubber layer. Fabric material is provided on one of the inside and outside of the body. The fabric material is treated with a mixture of carbon-black-dispersed liquid and resorcinol-formalin-latex liquid.
