Abstract: It is an object of the present invention to provide a double-sided adhesive sheet having strong adhesive force and excellent reworkability. The present invention relates a double-sided adhesive sheet having an acrylic adhesive layer and a silicone adhesive layer directly laminated on the acrylic adhesive layer, wherein the interfacial adhesive force between the acrylic adhesive layer and the silicone adhesive layer is 1 N/25 mm or more.

Abstract: There are provided electrophotographic transfer sheets comprising a substrate sheet which is a laminate comprising a thermoplastic resin film layer (A) adhesively laminated on at least one side of a core material layer (B) made of a paper substrate or a thermoplastic polyester-based resin film, and a toner receiving layer composed mainly of a conductive metal oxide coated on the surface of the thermoplastic resin film layer (A), characterised by having a Clark stiffness of at least 12 cm in the cross direction as measured according to JIS P8143.

Abstract: A motorcycle engine having an exhaust passage air introduction system. Each cylinder includes two exhaust passages which are joined at a point displaced from the engine. Air is introduced into one of the exhaust passages of the two so as to more fully combust the unburned gasses within the exhaust passage and then to more fully combust the unburned exhaust in the joined passage. The timing of the valves associated with each exhaust passage is such that the valve associated with the passage having the air inlet has advance timing. A chain tensioner for the timing chain includes a tensioner cylinder hydraulically actuated by the engine oil. A gasket having an orifice therein is positioned between components in the oil passageway extending to the tensioner cylinder. The oil cooling system of the engine includes an oil filter and an oil cooler which are displaced from one another and mounted to a common base which is in turn mounted to the engine.

Abstract: A lignosellulose-phenolic compound composite product having a weight ratio of the lignocellulose material to the phenolic compound of 0.4/1.0 to 5.0/1.0 is prepared by heat-dissolving the lignocellulose material in a solvent comprising, as a main component, at least one phenolic compound, optionally in the presence of a dissolving acid catalyst, and then adjusting the amount of the phenolic compound to a level of 1/0.4 to 1/5.0 of the weight of the lignocellulose material, in which heat-dissolving step water generated, as a by-product, from the reaction of the lignocellulose material with the phenolic compound is preferably eliminated, to allow the temperature of the reaction system to rise and thus promote the heat-dissolving reaction.
