  • Publication number: 20210310972
    Abstract: A particulate-matter detecting sensor including an insulating substrate which has a detecting face, a plurality of detecting conductors formed in the insulating substrate, and a heating section embedded in the insulating substrate. Each of the plurality of detecting conductors includes a detecting electrode part, a terminal part, and a connecting part. An exposed conductor part of the detecting conductor which is exposed to the element surface is constituted of a noble metal conductor mainly formed of at least one noble metal selected from Pt, Au, Pd, Rh and Ir. At least a portion of a non-exposed conductor part of the detecting conductor which is not exposed to the element surface is constituted of a low expansion conductor mainly formed of a low expansion coefficient metal which linear expansion coefficient is lower than that of the noble metal.

  • Publication number: 20210199611
    Abstract: A particulate-matter detecting sensor including an insulating substrate which has a detecting face, detecting conductors formed in the insulating substrate, and a heating section formed on the insulating substrate. Each detecting conductor includes a detecting electrode part, a terminal part, and a connecting part. A portion of the detecting conductor is constituted of a noble metal conductor mainly formed of at least one noble metal selected from Pt, Au, Pd, Rh and Ir. At least a portion of the connecting part is formed of a low expansion conductor mainly formed of a low expansion coefficient metal having linear expansion coefficient lower than that of the noble metal. Both conductors are joined at an overlapping part at which the noble metal conductor and the low expansion conductor are partly overlapped with each other on an insulating layer forming the insulating substrate in a normal line direction of the insulating layer.

  • Patent number: 9724634
    Abstract: An object of the present invention is to provide a honeycomb filter capable of achieving a combination of high collection efficiency and low pressure loss. The honeycomb filter comprises a ceramic honeycomb substrate in which a multitude of cells through which a fluid flows are disposed in parallel in a longitudinal direction and are separated by cell walls, each cell being sealed at an end section at either the fluid inlet side or the fluid outlet side, and a filter layer which, among the surfaces of the cell walls, is formed on the surface of the cell walls of those cells in which the end section at the fluid inlet side is open and the end section at the fluid outlet side is sealed by a sealing material, wherein the thickness of the filter layer increases gradually from the fluid inlet side toward the fluid outlet side.

  • Publication number: 20150121825
    Abstract: An object of the present invention is to provide a honeycomb filter which is resistant to detachment of the filter layer during regeneration processing, while suppressing any sudden increase in pressure loss caused by depth filtration. The honeycomb filter of the present invention comprises a ceramic honeycomb substrate in which a multitude of cells through which a fluid flows are disposed in parallel in a longitudinal direction and are separated by cell walls, each cell being sealed at an end section at either the fluid inlet side or the fluid outlet side, and a filter layer which, among the surfaces of the cell walls, is formed on the surface of the cell walls of those cells in which the end section at the fluid inlet side is open and the end section at the fluid outlet side is sealed, wherein the filter layer comprises hollow particles.
