  • Patent number: 11786628
    Abstract: An air purifier according to an aspect of the present disclosure includes: an air passage defined between a first inner wall surface and a second inner wall surface that are planar and face each other, having a flat passage cross section in which a distance between the first inner wall surface and the second inner wall surface is small, and meandering in a plane parallel to the first inner wall surface and the second inner wall surface; a catalyst member including a support having a flat mesh shape, and a photocatalyst supported on the support, the catalyst member being disposed parallel to the first inner wall surface and the second inner wall surface in the air passage; and a plurality of light sources dispersed on the second inner wall surface, and configured to irradiate the catalyst member with light that activates the photocatalyst.

  • Patent number: 10711170
    Abstract: The present invention provides a two-component type urethane-based adhesive composition for an automobile, which has a good productivity because of high curing rate, which there is not much change between physical properties of a cured product formed from a first component alone and those of a cured product formed from a mixture of first and second components, and which it is possible to satisfy required performances for an automotive adhesive without the second component.
