  • Patent number: 11430605
    Abstract: There is provided a method for producing metal foils, capable of easily crystalizing amorphous soft magnetic material of a plurality of metal foils into nano-crystal magnetic by uniformly heating the metal foils. Separating members (magnets) are disposed on the opposite sides of a laminate, which has been obtained by laminating a plurality of metal foils made of amorphous soft magnetic material, in the laminated direction of the laminate, and the metal foils forming the laminate are magnetized with the magnets. Thus, the adjacent metal foils are separated from each other in the laminated direction and a gap is formed between the metal foils. The metal foils are heated with the gap formed therebetween so that the amorphous soft magnetic material of each metal foil is crystalized into nano-crystal magnetic material.

  • Patent number: 11326225
    Abstract: There is provided a metal sheet producing method that can avoid a decrease in magnetic properties. The metal sheet producing method is a method for producing metal sheets by applying heat treatment to metal sheets made of amorphous soft magnetic material while conveying the metal sheets along a bar and thus crystallizing the amorphous soft magnetic material into nano-crystal soft magnetic material. The method includes attaching the plurality of metal sheets in a laminated state to an upstream portion of the bar, separating the plurality of metal sheets from each other using magnetic force and moving the metal sheets while applying heat treatment thereto so as to allow them to pass by a midstream portion of the bar, and sequentially laminating the metal sheets that have passed by the midstream portion on a downstream portion of the bar.

  • Patent number: 11092290
    Abstract: An amount Y of liquid hydrogen that has passed through a first valve and has been volatilized during a predetermined time after first and second valves are opened is calculated by using a pressure P0 in an internal space of a liquid hydrogen tank measured before the two valves are opened, a pressure P1 in the internal space measured after the lapse of the predetermined time since the two valves are opened, and an amount X of the gaseous hydrogen that has passed through the second valve during the predetermined time. A fluid level H of the liquid hydrogen in the liquid hydrogen tank after the lapse of the predetermined time since the two valves are opened is calculated by using a expression showing a relationship between the H and an amount Y1 of the liquid hydrogen that passes through the first valve and drops therefrom, and the Y.

  • Publication number: 20210207238
    Abstract: There is provided a method for producing metal foils, capable of easily crystalizing amorphous soft magnetic material of a plurality of metal foils into nano-crystal soft magnetic material by uniformly heating the metal foils. A laminate obtained by laminating the metal foils made of amorphous soft magnetic material is held by a holding member such that adjacent metal foils can be separated from each other in a laminated direction of the laminate. By conveying either the holding member or magnets in a direction perpendicular to the laminated direction as a conveying direction such that the holding member and the magnets come close to each other, the adjacent metal foils are separated from each other with a magnetic force of the magnets. The separated metal foils are heated to crystalize the amorphous soft magnetic material of the metal foils into nano-crystal soft magnetic material. The same magnetic pole of the magnets aligns in the laminated direction.
