摘要： An improved structure of a gas sensor is provided which includes a hollow housing and a sensing element. The sensing element has a flange and is disposed within the housing in engagement of the flange with an inner wall of the housing. An insulating powder is packed in a chamber defined by the inner wall of the housing, the flange and an outer wall of the sensing element to provide an air-tight seal between an air chamber to which one end of the sensing element is exposed and a gas chamber to which the other end of the sensing element is exposed. The air-tight seal has the structure designed to minimize an air leakage and breakage of the sensing element when installed in the housing.

摘要： The purpose of the present invention is to provide a gasket material that is capable of preventing corrosion caused by sulfur element, can be used as a seal part for a product that is easily damaged by corrosion, such as an electronic part, and is capable of forming a tight seal under low surface pressure with a material having low rigidity and inadequate reliability such as to have a blowhole, and that can prevent reduction in bolt axial load without producing plastic flow (setting) under pressure. The purpose is achieved by a gasket material in which a foamed rubber layer having a closed cell structure is formed, via an adhesive layer, on at least one side of a metal plate, wherein the foamed rubber layer comprises a carboxyl group-modified nitrile rubber, the expansion ratio of the foamed rubber layer is 2.0 to 3.0, and the foamed rubber layer is crosslinked with an epoxy compound.
