20090229912MUFFLER - A muffler has a casing with a plurality of sound-muffling chambers, exhaust pipes that pass through at least two sound-muffling chambers and to pass through exhaust from an engine, a plurality of apertures provided in each exhaust pipe, and a plurality of valves provided in each of the apertures. In this muffler, the plurality of apertures are provided at the locations at which an exhaust flow from one aperture and an exhaust flow from another aperture do not interfere with each other. When there are two apertures, the apertures are provided at positions in the exhaust pipes at which the apertures do not face each other. For this reason, by avoiding interference between exhaust flows from the two apertures, it is possible to suppress an abnormal sound caused by the interference.09-17-2009

20080311396Pressure-Sensitive Adhesive Sheet for Application to Skin - The problem of the present invention is to provide a pressure-sensitive adhesive sheet for skin adhesion, having an adhesive layer, which can be formed without using an organic solvent, shows superior adhesion performance to the skin, and shows extremely mild irritation to the skin and stratum corneum damage. To solve the problem, the present invention provides a pressure-sensitive adhesive sheet for skin adhesion, which has a substrate and an adhesive layer laminated on the substrate, wherein the adhesive layer is obtained by curing an adhesive composition containing polyether polymer (A) having at least one alkenyl group on the terminal, compound (B) having 1-10 hydrosilyl groups in a molecule and hydrosilylation catalyst (C).12-18-2008
