摘要： A method of fabricating a sintered ceramic composite body having at last one hollow portion therein is disclosed. According to this method, at least one green ceramic body in the form of a sheet or plate and an adhesive sheet made of a ceramic powder and a binder resin are provided. The adhesive sheet is capable of adhering to the green ceramic body after drying and is shaped to provide a hollow portion in association with green ceramic body. The adhesion body and the green ceramic body are brought into intimate contact with each other so that a hollow portion is established therebetween. The resulting composite body is pressed and sintered to obtain a sintered ceramic composite body having the hollow portion therein. The binder preferably includes acrylic resin(s) and/or vinyl resin(s) having a molecular weight of 300,000 to 800,000 and a glass transition temperature of -30.degree. C. or below.

摘要： A gas sensor element is inserted into a housing having a base end and is fixed with respect to the housing. Terminal electrodes are provided on the base end of the sensor element. An atmosphere-side cover including an insulator with terminal accommodation holes is provided on the base end of the housing. The insulator also has an element accommodation hole (communicating with the terminal accommodation holes) in which the base end of the sensor element is placed. The insulator has ribs forming inner surfaces defining the element accommodation hole. The rib thickness is smaller than that of the sensor element base end. Metal terminals are at least partially placed in respective terminal accommodation holes and have connecting portions with leads for external electrical connection. The ribs are located between the metal terminals to form spaces between the metal terminals. As the sensor element base end is placed in the element accommodation hole, terminal electrodes on the base end come into contact with the metal terminals and thereby electrically connected with the leads.

摘要： A detecting unit of an oxygen sensor as an A/F sensor has a solid electrolyte layer and a diffusion resistance layer and generates a current value according to the concentration of oxygen in an exhaust gas by applying a voltage across electrodes on an exhaust gas side and an atmosphere side of the solid electrolyte layer. An oxygen supply/exhaust unit has a solid electrolyte layer and a pair of electrodes formed on both faces of the solid electrolyte layer, and supplies oxygen near to the electrode on the atmosphere side of the detecting unit or exhausts oxygen near the electrode. A control unit controls, in response to a limit current value detected by a current detection unit, the amount of supply or exhaust of oxygen of the oxygen supply/exhaust unit on the basis of the detected current value. A control target value of a current flowing in the solid electrolyte layer is variably set so that amount of oxygen moving in the solid electrolyte layers are equal, thereby controlling the amount of supply or exhaust of oxygen of the oxygen supply/exhaust unit.
