  • Patent number: 11892422
    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: 11814304
    Abstract: A process of dissolving into to-be-treated water a peroxodisulfate and metal ions other than ions of alkali metals is performed by pouring equipment. An ultraviolet irradiation apparatus performs a process of treating the to-be-treated water, having the peroxodisulfate and the metal ions other than ions of alkali metals dissolved therein, with ultraviolet rays. By performing UV treatment on the to-be-treated water having the peroxodisulfate and metal ions dissolved therein, the inventive method and system achieve improved TOC decomposing performance and thus can particularly decompose a urea component in an efficient manner. Further, the to-be-treated water may be treated with an ion-exchange resin at a subsequent stage in such a manner that organic acids contained in the to-be-treated water having been subjected to the UV treatment are adsorbed to the ion exchange-resin, with the advantageous result that the concentration of TOC present in the to-be-treated water can be reduced.

  • 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: 20050284278
    Abstract: Sheet cutter minimizing friction occurred between a slider and a guide rail while transferring the slider along the guide rail in a high linearity. Each of the slider and the guide rail has either a convex or a concave portion up and down to fit each other. In cutting processes only the convex and concave portions are made abutted each other contributing to minimization of the friction and smooth transferability of the slider in a high linearity.
