A method of producing a rubber seal includes placing a screen with an opening, above a workpiece including a base portion and a bead base protruding from the base portion and applying a liquid material for forming the rubber seal, onto a top part of the bead base through the opening. In the production, the liquid material is applied onto the top part by moving a squeegee along a surface of the screen in a state where a stopper portion is disposed at a position adjacent to the bead base within an area of the base portion and between the screen and the workpiece.

Method of producing rubber seal

A metal separator is applied to a fuel cell. A method of producing the metal separator involves performing a plate processing step of forming a bead base, and a rubber seal forming step of providing a rubber seal by screen printing for the bead base formed in the plate processing step. The rubber seal forming step includes a first protrusion forming step of forming a first protrusion at the central part in the width direction of a top portion of the bead base, in a cross sectional view taken along a thickness direction of the rubber seal, and a second protrusion forming step of forming a second protrusion configured to cover the first protrusion after the first protrusion forming step.

A piston for an internal combustion engine, the piston having a skirt part, comprises: a resinous coating layer formed on a surface of the skirt part; and a plurality of concaves regularly arranged in the resinous coating layer. The concaves are non-coated regions in which said resinous coating layer is not formed.

An expansion graphite sheet of high thermal resistance includes an expansion graphite as a main component, and inorganic thermal resistance particles made of at least one selected from the group consisting of aluminum boride (AlBand/or AlB), silicon boride (SiB), zinc boric acid (2ZnO.3BO.3.5HO) and phosphorous boride (PB). An exhaust gasket made of the expansion graphite sheet, in addition to the expansion graphite sheet, can exhibit high thermal (oxidization) resistance under a high temperature of 600&#x2013;700&#xb0; C.

A compound sheet gasket which exhibits superior sealing durability to fretting is provided. The compound sheet gasket is mounted between a housing and a cover provided at an opening of the housing, and the friction coefficient of any one surface of a front surface adhered to the housing by the flexibility thereof and a rear surface adhered to the cover by the flexibility thereof, is set to be 1.15 times or more that of the other.

Compound sheet gasket

Disclosed is a metal gasket which is capable of securing a sealing properties by strongly pressing a portion of a bead thereof, which faces a portion where a pressuring surface of one joining surface of one of an intake manifold and an EGR plate does not exist, to the other joining surface thereof. A metal gasket which is clamped between the two joining surfaces and has at least one hole for fluid, includes a bead for sealing the two joining surfaces, the bead surrounding the at least one hole for fluid, each of which allows openings for fluid to be communicated with each other, the openings being provided in the respective joining surfaces. The metal gasket further includes a convex portion, the tip of which abuts one of the joining surfaces, is provided in the vicinity of a portion of the beads abutting the other joining surface.

Metal gasket

Provided is a gasket capable of maintaining a high sealing property under a high temperature, in which a gasket basic substance and coverture are not sublimated or decomposed when the gasket is used under a high temperature above 500&#xb0; C. The gasket for a high-temperature joint includes a gasket basic substance formed by filling a heat-resistant filler mainly composed of diatomaceous earth into gaps of a meshed metallic reinforcing member, and coverture made of a heat-resistant antifriction material mainly composed of a mixture of boron nitride and polytetrafluoroethylene resin for covering a surface of the gasket basic substance.

The composite material for a metal gasket includes a metal plate; a rubber layer fixed on the surface of the metal plate; and a solid lubricant layer fixed on the rubber layer. The solid lubricant layer contains polytetrafluoroethylene and a resin as main components, and has a friction coefficient equal to 0.15 or lower. Thus, the seal durability of the metal gasket is improved by effectively preventing fretting wear.

A variable geometry turbocharger in which a bill-like projection portion is arranged in a part of an outer periphery of a flow passage spacer, and the projection portion is protruded to a turbine rotor side at a predetermined angle or the projection portion is movably provided. Alternatively, a rod-like member is arranged in a part of an outer periphery of a flow passage spacer and the rod-like member is arranged so as to be adjacent to the turbine rotor side at a predetermined angle. Alternatively, a guide vane in which a leading edge side of a rotational shaft is eliminated is arranged in a part of an outer periphery of a flow passage spacer and the rotational shaft is arranged so as to be adjacent to the turbine rotor side at a predetermined angle. Further, a heat resisting cast steel having a little amount of carbon is employed as a material for a casing and a guide vane table sectioning the turbine chamber, and without using the flow passage spacer and in place of the flow passage spacer, both side walls sectioning the turbine chamber themselves keep a gap with respect to the guide vane minimum. Accordingly, a high turbine efficiency can be obtained by preventing a gas stream from being separated at the back of a flow passage spacer and inside a guide vane, since a hydraulic energy loss is reduced and a uniform and high average flow speed distribution is realized at a position of an inlet of a turbine rotor.
