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.

Abstract: A formed activated carbon has a Kiya crushing strength of 1 kg or more and a specific heat of 0.4 J/K·cc or more at 25° C.

Abstract: A fuel vapor treatment canister is described. The canister includes a casing having first and second end walls between which an inside space is formed. The first end wall has a first opening in communication with a fuel tank, and a second opening in communication with an air intake passage of an engine. The second end wall has a third opening in communication with the atmosphere. The inside space includes first and second chambers. The first chamber is located closer to the first end wall than the second chamber. A first fuel vapor adsorbing material is disposed in the first chamber. A second fuel vapor adsorbing material and a heat-accumulative material are disposed in the second chamber. The heat-accumulative material is larger in specific heat than the second fuel vapor adsorbing material.

Abstract: A resonator type silencer connected to an air intake duct of an automotive internal combustion engine. The resonator type silencer comprises a first case having an open end section. A second case is fabricated separate from the first case. The second case has an open end section which is joinable with the open end section of the first case. The open end section of the first case includes an end edge portion having a linear projection extending along the end edge portion. The linear projection has an inclined face extending along the end edge portion and sloped down in a direction toward a surface of the open end section. The open end section of the second case includes an end wall portion. A guide wall is integral with the end wall portion and extending along an end edge portion of the open end section to define a groove extending along the end edge portion.

Abstract: An oil filter unit comprising a housing (4) and a filter element (14) accommodated therein is fitted to an engine (1) via a bracket (3) having a cylindrical holder (5). The housing (4) is secured to the holder (5) by screwing a male screw (19) on its outer circumference to a female screw (17) formed in the inner circumference of the holder (5). A first cut-out (24) is formed across the female screw (17) and a second cut-out (23) is formed across the male screw (19). When these cut-outs (24, 23) meet together, they form a drain passage which drains the oil in the housing (4) to outside. With this construction, the oil in the housing is drained via a predetermined path and prevented from scattering around, when the filter unit is removed from the engine (1).

Abstract: A vapor treatment system incorporated with an automotive fuel storage tank for a gasoline. The vapor treatment system comprises a vapor adsorbent canister containing therein vapor adsorbent. A first ventilation line is provided to have a first end section connected to an upper space inside the storage tank, and a second end section connected to the vapor adsorbent canister. A vapor control valve is disposed in the first ventilation line to control flow of vapor of the gasoline passing through the first ventilation line. A second ventilation line is provided to have a first end section connected to a liquid supply pipe through which the gasoline is supplied into the storage tank, and a second end section connected to the vapor adsorbent canister. A vapor-liquid contacting device is provided to include a container disposed inside the storage tank. A return line is provided such that the gasoline is returned from an engine through it into the storage tank.
