摘要： A gas sensor measuring a given component content in a gas is provided which has an outer and an inner metallic cover, a sensing unit, and an insulator. The sensing unit consists of a measuring electrode to be exposed to the gas to be measured and a reference electrode to be exposed to a reference gas in a reference gas chamber. The measuring electrode and the reference electrode are disposed adjacent each other through a solid electrolyte body. The inner metallic cover is installed on an end of a sensor housing. The outer metallic cover is installed on the periphery of the inner metallic cover. The insulator is mounted within the inner metallic cover and has formed therein holes through which sensor signal pickup leads pass. The insulator has an outer wall different in geometry from an inner wall of the inner metallic cover to define a portion of a reference gas passage therebetween which leads to the reference gas chamber.

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： An improved structure of a gas sensor is provided. The gas sensor includes a gas sensitive element, a holder retaining therein the gas sensitive element, and a protective cover installed on the holder. The protective cover has a flange which is retained in a groove formed in the holder by crimping an outer extension formed on the holder adjacent the groove. The geometries of the groove in the holder and the flange of the protective cover are so determined as to provide for ease of installation of the protective cover on the holder, firm engagement of the protective cover with the groove of the holder, and ease of machining of the groove of the holder.

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.
