  • Patent number: 7795174
    Abstract: A catalyst for purifying exhaust gases includes a carrier substrate and a catalyst layer which is carried on the carrier substrate and contains a noble metal, a porous oxide and an additional oxide containing at least one selected from the group consisting of Ni, Bi, Sn, Fe, Co, Cu and Zn. Only a downstream section of the carrier substrate, which is located on a downstream side of an exhaust gas stream contains the additional oxide, whereas an upstream section of the carrier substrate does not contain the additional oxide. With this arrangement, in the upstream section of the carrier substrate, the noble metal and the additional oxide do not exist together so that the noble metal is not deteriorated with the additional oxide. As a result, in the upstream section, the purification performance as a three-way catalyst is favorably achieved, thereby restraining the emission of H2S while maintaining the three-way performance.

    Abstract: There is provided a connection structure in which concentration of current in a connection portion of wirings, or of an element and a wiring is prevented. Three slits are formed in each of a first wiring and a second wiring, which extends in a direction perpendicular to a direction in which the first wiring extends, so that distances from the side of a cross internal angle gradually become longer. A portion of a current path is changed by these slits so as to limit current which can flow through the cross internal angle.
