Abstract: The present invention is mainly configured of a separator for an electric double-layer capacitor that comprises an aramid fiber, a polyester fiber, a glass fiber, and a silica (inorganic compound for forming hydrosol) containing a particulate silica (particulate inorganic compound) of not less than 1 nm and not more than 500 nm, wherein total of the silica and the glass fiber is not less than 10 mass percent and not more than 50 mass percent; the electric double-layer capacitor comprising the separator; and a manufacturing method of the separator for the electric double-layer capacitor which method comprises a mixing process for mixing the aramid fiber, the polyester fiber, the glass fiber, and the silica sol and a paper making process for making paper from the mixture.

Abstract: An air intake device for use with an internal combustion engine has an air cleaner case adapted to be mounted on the engine to extend longitudinally along an upper wall of the engine. An opening is formed in a longitudinal end portion of a bottom wall of the air cleaner case. An air cleaner body has an open end that is connected to the opening of the bottom wall of the air cleaner case thereby to communicate an interior of the air cleaner body with that of the air cleaner case. An air cleaner element is put between the air cleaner body and the air cleaner case in a manner to extend across the opening of the bottom wall of the air cleaner case.

Abstract: A seal member adapted to be mounted between a cylinder head cover and an ignition plug tube comprises a mount portion interposed radially movably between an upper surface of an annular stepped portion formed around an opening of the cylinder head cover for insertion of the ignition plug tube and a baffle plate. A first seal portion and a second seal portion project radially outward and inward, respectively, from the mount portion to be brought into contact with a peripheral surface of the annular stepped portion and the ignition plug tube, respectively. The second seal portion can be elastically deformed following relative radial movements between the mount portion and the ignition plug tube.
