    摘要: A reinforced plate-like laminated sintered body is produced by the steps of providing a green laminate with an alumina-based layer including zirconia provided at least partly over one surface of the base material and simultaneously sintering the laminated surface layer and base material layer. The thickness ratio of the surface layer with respect to the base material layer is in the range of 1/100 to 20/100 and the laminate has a ratio of shrinkage moduli, calculated as the ratio of the shrinkage modulus of the base material layer when sintered alone to the shrinkage modulus of the surface layer when sintered alone, within the range of 1.01 to 1.08.

    摘要: An air-fuel ratio sensor including a box member having a wall made of oxygen ion-conductive electrolyte having a pair of porous electrodes on opposite sides and a diffusion-limiting portion providing communication between the inside and outside of the box member, and an oxygen gas sensing element formed within the box member by injection and firing. The oxygen gas sensing element has a resistance which varies in accordance with the oxygen partial pressure of the atmosphere in which the sensor is immersed.
