  • Heat-insulation material and production method thereof
    Patent number: 10384420
    Abstract: A heat-insulation material, includes: a first substrate layer that includes an aerogel and first fibers; and a second substrate layer that is layered on the first substrate layer and that includes an aerogel and second fibers, wherein a volume density of the aerogel in the first substrate layer is larger than a volume density of the aerogel in the second substrate layer, and an amount of the aerogel that is present around a first surface of the second substrate layer inside the second substrate layer, not adjacent to the first substrate layer, is smaller than an amount of the aerogel that is present around a second surface (inside the second substrate layer adjacent to the first substrate layer.
    Type: Grant

  • Composite sheet, mounting structure including the composite sheet and electronic apparatus including the mounting structure
    Patent number: 9604431
    Abstract: A composite sheet includes: a graphite layer that is disposed on a high temperature portion; an aerogel layer that is disposed on a low temperature portion; and an adhesive layer to which the graphite layer and the aerogel layer are fixed, in which the adhesive layer is formed of a water-based adhesive. The water-based adhesive layer is formed of an adhesive containing water as a solvent or an adhesive containing water as a raw material. The water-based adhesive layer includes gaps.
