摘要： An air-fuel ratio sensing element comprises a pump cell having at least one pair of pump electrodes thereon, a sensor cell having at least one pair of sensor electrodes thereon, and a gas chamber having two surfaces defined by the pump cell and the sensor cell. Two to five gas holes, each having approximately the same diameter and communicating with the gas chamber, are provided for introducing sensed gas into the gas chamber. The gas holes form their projection images on the surface of the sensor cell which has a sensor electrode thereon and faces the gas chamber. The sensor electrode is shaped such that it is dividable into a plurality of similar subsections defined by virtual lines connecting the geometric centroid of the sensor electrode and the center of the projection image of each gas hole.

摘要： An air fuel ratio detecting apparatus by which a stable oxygen ion limit current may be obtained, including a working electrode and a gas diffusion resistance layer laminated in this order on a first surface of a solid electrolyte. An ambient air introduction duct and an electric heater are laminated in this order on a second surface of the electrolyte. The gas diffusion resistance layer is composed of a gas permeation layer and gas shield layer, which is provided on a surface of the gas diffusion resistance layer. Since the surface of the gas permeation layer is covered by the gas shield layer, the gas to be measured enters into the gas diffusion resistance layer from only side faces of gas diffusion resistance layer. A cell is preferably baked in a one-piece manner. A porosity of the gas permeation layer is in a preferable range of from about 2 to about 60%, a thickness of the gas permeation layer is preferably in a range of from about 5 to about 300 .mu.m, and a porosity of the gas shield layer is preferably no more than 10%. Also, the periphery of the cell is preferably covered by a protective layer.

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 gas concentration detector comprises a plate sensor element including a sensing action and a signal output section. A flange section is formed between the sensing section and the signal output section so as to protrude in the lateral direction thereof. A cylindrical housing has an inside space for receiving the sensor element. Powder is disposed in the inside space of the cylindrical housing at a predetermined position adjacent to the flange section so that the sensor element is airtightly fixed to the housing by applying a pressing force on the powder. Furthermore, a cross-sectional area of the signal output section is larger than a cross-sectional area of the sensing section.
