  • Patent number: 11930707
    Abstract: A thermoelectric power generation device including a thermoelectric element having a first side provided to a heating unit and a second side provided to a cooling unit, and a heat transfer pipe arranged in a passage in which a high temperature fluid flows. The heating unit and the heat transfer pipe have internal spaces communicating with each other. The internal space of the heating unit and the internal space of the heat transfer pipe form a circulation path in which a heat medium is circulated. An outlet of the heat transfer pipe from which the heat medium is discharged is provided in a position higher than an inlet of the heat transfer pipe into which the heat medium flows. The heat transfer pipe vaporizes the heat medium flowing in the circulation path by using heat of the high temperature fluid. The heating unit condenses the heat medium vaporized.

  • Patent number: 8883662
    Abstract: A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer 1, substrate layer 2, substrate layer 3 and back layer in this order along the thickness direction, part of the microfine long fibers forming the surface layer and/or the back layer are fuse-bonded to each other and the microfine long fibers forming the intermediate layer are not fuse-bonded. With such a fuse-bonding state of the microfine long fibers, the (semi)grain-finished leather-like sheet combines a low compression resistance and a dense feel each comparable to natural leathers, has a sufficient practical strength, and are excellent in properties which are required according to its use.

  • Patent number: 8778126
    Abstract: A method of producing a substrate suitable for artificial leathers. The substrate is composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate having the surface substantially free from the binder resin. The peeling strength between the substrate and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate is substantially free from the binder resin.
