Abstract: A composite hose is constructed to have an outer peripheral portion and an inner peripheral portion. The outer peripheral portion includes an elastic layer and a reinforcing layer provided on an outer periphery of the elastic layer. The inner peripheral portion includes a corrugated metal tube which is provided with a corrugated portion formed with corrugation hills and corrugation valleys. A distance between the reinforcing layer and tops of the corrugation hills of the corrugated metal tube is designed 0.27 mm or less.

Abstract: The present invention relates to a metallic tubular hose which suppresses disintegration in which the metallic tubular hose comprises a hose body having a longitudinal edge at one end thereof and a bellows metallic tube inner layer with the inner layer composed of a corrugated bellows portion and a restricted portion, a jacket composed of a plurality of layers surrounding the inner layer, a rigid insert pipe extending into the hose body and a metallic sleeve engaging the hose body along said longitudinal edge for compressing said jacket against said rigid insert pipe wherein said plurality of layers in said jacket includes an inner layer adjacent to said restricted portion of said bellows metallic tube inner layer composed of a flexible and hard material possessing a tensile modulus of between 4 MPa and 8 MPa for a composition of rubber and about 300 MPa for a resin material composition and preferably between 1000 MPa and 6000 MPa.

Abstract: A composite hose comprises a corrugated metal tube as barrier layer against permeation of conveyed fluid and a reinforcing layer which is formed by braiding a reinforcing wire member made of a metal wire. A braid density of the reinforcing layer is 55% or less.

Abstract: A composite hose is provided with a corrugated metal tube as a barrier layer against permeation of conveyed fluid, and an elastic filler layer which is filled in valley gaps between corrugation hills on an outer peripheral side of the corrugated metal tube. The elastic filler layer is filled completely in the valley gaps to tops of the corrugation hills. A radial thickness of the elastic filler layer measured radially outwardly from a radial position of the tops of the corrugation hills is designed 0.3 mm or less.

Abstract: A composite hose is provided with a corrugated metal tube of an inner layer and rubber filler which is filled in valley gaps between corrugation hills on an outer peripheral side of the corrugated metal tube. A tubular hard resin layer is further provided as cover layer on an outer side of the corrugated metal tube in order to enclose the rubber filler within the valley gaps to prevent the rubber filler from escaping radially outwardly.

Abstract: A hinge mechanism having first and second pivot shafts held by first and second hinge base members, respectively, which also connect to ends of a hinge arm member. First and second cams on the first and second hinge base members engage first and second control levers on the ends of the hinge arm members. First and second cam portions are provided by the opposed ends of the hinge arm member respectively and engage first and second pivotable check plates. First and second follower members are mounted on the first and second check plates respectively and contactable with the first and second cam portions respectively. First and second springs bias the first and second check plates in a direction to press the first and second follower members on the first and second cam portions respectively. A third spring biases a link member toward the first hinge base member.

Abstract: A process for manufacturing zinc-silica composite plated steel performed by electrolyzation in a galvanization bath containing fine grains of silica, particularly colloidal silica fine particles. Surfactant having cationic property, such as polyoxyethylenelaurylamine or dodecyltrimethylammonium chloride is further added to the galavinization bath so that a zinc-silica layer is formed over the steel. The plated steel surfaces are further treated with a silane coupling agent, such as gamma-aminopropyltriethoxysilane. The steel plated with zinc-silica composite thus obtained has excellent resistance against corrosion and adhesion to organic paints or organic adhesives. The steel is suitable for various steel members and sheet iron for automobile bodies and parts which require high corrosion resistance.
