摘要:
In a magnetic refrigeration device, magnetic bodies having a magnetocaloric effect and solid heat accumulation members having heat accumulation effect are arranged alternately with gaps therebetween. Magnetic field apply units start and stop application of magnetic fields to the magnetic bodies. A contact mechanism brings each of the magnetic bodies into contact with one of the solid heat accumulation members adjacent to the each magnetic body. Alternatively, the contact mechanism brings each of the solid heat accumulation members into contact with one of the magnetic bodies adjacent to the each solid heat accumulation members.

According to one embodiment, an information recording and reproducing device includes a first layer, a second layer and a recording layer. The recording layer is provided between the first layer and the second layer and being capable of reversibly changing between a first state having a first resistance and a second state having a second resistance higher than the first resistance by a current supplied via the first layer and the second layer. The recording layer includes a first compound layer and an insulating layer. The first compound layer contains a first compound. The first compound includes a first cation element and a second cation element of a type different from the first cation element. The insulating layer contains a third compound, and the third compound includes an element selected from group 1 to 4 elements and group 12 to 17 elements in the periodic table.

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.
