  • Patent number: 9222708
    Abstract: According to one embodiment, a magnetic refrigeration device includes magnetic bodies, a magnetic field application unit, a thermal storage medium, and a heat transfer unit. The magnetic bodies are arrayed at an interval. The application unit applies and removes a magnetic field to and from the magnetic bodies, respectively. The medium is arranged to face at least one of the magnetic bodies. The medium has no Curie point within a range of a temperature change of the magnetic bodies and removal. The heat transfer unit selectively brings the medium into thermal contact with the magnetic bodies or thermally isolates the medium from the magnetic bodies, and transfers heat from the magnetic bodies to the medium or from the medium to the magnetic bodies in synchronism with magnetic field application and removal.

  • Patent number: 9114592
    Abstract: According to a first aspect of the invention, a method for manufacturing a concave-convex pattern includes the steps of heating a sheet-like member, compressively bonding the sheet-like member, removing the sheet-like member after the compressively bonding, and transferring a pattern shape of a reverse concave-convex pattern layer to a surface of the substrate. The sheet-like member has a concave-convex pattern block on at least one of surfaces thereof, and is given flowability thereto by heating. The reverse concave-convex pattern layer is formed on the one of the surfaces, and continues over two or more concaves of the concave-convex pattern block so that the reverse concave-convex pattern layer meshes at least partially with the concave-convex pattern block. At least the reverse concave-convex pattern layer is left on the substrate. Here, the one of the surfaces has the concave-convex pattern block.

    Abstract: A structure includes a substrate, a first layer formed on the substrate, and a second layer formed on the first layer. The first layer is comprised of self-assembled monolayer and contains 4-(6-hydroxyhexyloxy)-4?-methoxybiphenyl. The second layer is obtained by micro-phase separation of a block copolymer containing a hydrophilic polymer comprised of polyethylene oxide and a hydrophobic polymer comprised of polymethacrylic acid containing azobenzene at the side chain. The second layer contains a cylinder phase with its long axis being oriented perpendicular to the substrate. The thickness T of the second layer is within a range of A?T?50 nm, where A is a phase separation period length satisfying 5 nm?A?50 nm.
