Abstract: A film capacitor having moisture resistance includes a capacitor element having (a) a multilayer structure made of stacked dielectric films or a wound dielectric film, each dielectric film having a metallic layer formed on its surface, and (b) a pair of outer electrodes electrically connected to the metallic layer, and a coating layer covering the capacitor element. The coating layer is made from at least one polysiloxane, at least one organometallic compound or a combination of the polysiloxane and the organometallic compound, wherein the organometallic compound is selected from the group consisting of organoaluminum compounds, organosilicon,compounds, organotin compounds and organotitanium compounds.

Abstract: An exhaust gas purifier for purifying combustion gases of engines, the device comprising at least one composite sheet which is formed by sandwiching a catalyst coated sheet of cloth between a pair of supporting nets of heat resistive metal, the composite sheet being disposed in an exhaust pipe in a manner such that the exhaust gas flows in the direction of and along the surfaces of the composite sheet and that the gas contacts the catalyst sheet through the supporting net. The composite sheet(s) are shaped or disposed in a rolled sheet with spacer means to form gas flow path between its layers, or a set of coaxial tubes of the composite sheet disposed with spaces for gas-flow, or a set of parallel-disposed flat composite sheets with spaces for gas-flow. The device is advantageous in low resistivity for the gas flow.

Abstract: A cylindrical catalyst element comprising a heat-resistant metal in the form of a wire mesh or the like, a silica cloth supported by the mesh and having a catalyst disposed on a surface thereof adjacent the interior of the cylinder, said element being disposed adjacent the interior wall of an exhaust system upstream of a main catalyst device for cleaning the exhaust gases of an internal combustion engine.

Abstract: A catalytic converter for purifying the exhaust gases from an internal combustion engine, wherein a plurality of catalytic layers are arrayed in series and spaced apart by a predetermined distance from each other, and bypass paths are provided in such a way that except for the last catalytic layer, a part of the exhaust gases may bypass each catalytic layer without making contact therewith and may directly flow into the next catalytic layer.
