摘要： A sensor element has a solid electrolyte body holding a reference gas side electrode and a measurement gas side electrode on surfaces thereof. The measurement gas side electrode is covered with a porous protective layer including a component as a lead getter, which reacts with lead contained in measurement gas. Accordingly, lead is removed from measurement gas by the protective layer not to be attached to the measurement gas side electrode. As a result, the sensor element can be used in measurement gas containing lead, without deteriorating responsibility and output thereof.

摘要： A ceramic heater which can be produced easily, induces no increase of production cost and can restrict the resistance change of a heating body due to migration. According to the present invention, a gap is formed between a ceramic sintered body and a heating body. Thus, migration in which cations are seized within the gap is caused so as to impede the cations from entering into the heating body. This makes it difficult for the cations to migrate and the volume in which the heating body is expanded is secured by the gap 13.

摘要： A catalyst-loaded ceramic filter made of a ceramic material capable of directly supporting a catalyst component thereon is capable of providing early activation of the catalyst with a low coefficient of thermal expansion and light weight, without compromising the high porosity of the filter substrate. A catalyst-loaded ceramic filter is made of a ceramic material of which one or more kinds of element among its constituent elements is substituted with an element other than the constituent elements, for example a ceramic material with a part of Si or other elements included in cordierite is substituted with W or Co, as a filter substrate of honeycomb structure having a number of cells separated by porous walls, and supporting a catalyst such as a noble metal directly on the W.

摘要： An improved structure of an oxygen sensing element installed in an oxygen sensor designed to measure an oxygen content in gases is provided. The structure includes a cup-shaped solid electrolyte body, an inner electrode, and an outer electrode. The solid electrolyte body has a portion exposed to the gases which has a given length. The inner electrode is formed on an inner wall of the solid electrolyte body and exposed to air. The outer electrode is formed on an outer wall of the solid electrolyte body and exposed to the gases through a protective layer. The oxygen content in the gases is measured based on output signals from the inner and outer electrodes. The outer electrode occupies an area on the outer wall of the solid electrolyte body within a range of 80% of the given length of the gas-exposed portion of the solid electrolyte body and has a thickness ranging from 1.2 to 3.0 &mgr;m. This allows the oxygen sensing element to determine the oxygen content in the gases precisely and to have an improved heat-resistance.

摘要： An oxygen sensor element includes a solid electrolyte having cavities on a surface thereof and an electrode formed on the surface of the solid electrolyte. In a method of producing the oxygen sensor element, a solution containing a noble metal compound for nucleus formation is first applied to an electrode forming portion of the solid electrolyte to form a coating film. Then, the coating film is heat-treated to form a nucleus forming portion where noble metal nuclei are deposited. Subsequently, metal plating is applied to the nucleus forming portion to form a plating film deeply entering the cavities. Thereafter, the plating film is burned to form the electrode deeply entering the cavities.
