  • Publication number: 20240150874
    Abstract: This grain-oriented electrical steel sheet includes a base steel sheet, a glass coating formed on the base steel sheet, and a tension-applied insulation coating formed on the glass coating, in the base steel sheet, a plurality of linear strains that extend continuously or intermittently in a direction intersecting with a rolling direction are present, and intervals in the rolling direction of the plurality of linear strains adjacent to each other are 10 mm or less, in a region where the strains are present, a closure domain is present, a length d of the closure domain in a sheet thickness direction from a surface of the base steel sheet is 30 to 60 ?m, a length w in the rolling direction is 200 ?m or less, and a ratio mid of a depth m from the surface of the base steel sheet where a compressive strain in the rolling direction present in the closure domain exhibits a maximum value to the length d is in a range of more than 0.30 and less than 0.90.

  • Patent number: 11970751
    Abstract: The grain-oriented electrical steel sheet according to the present embodiment is a grain-oriented electrical steel sheet having a base steel sheet (1), an intermediate layer (4) disposed to be in contact with the base steel sheet (1), and an insulation coating (3) disposed to be in contact with the intermediate layer (4). The grain-oriented electrical steel sheet according to the present embodiment includes a surface of the base steel sheet (1) having a strain region (D) which extends in a direction intersecting a rolling direction of the base steel sheet (1), and a crystalline phosphorus oxide M2P4O13 present in the insulation coating (3) on the strain region (D) in a cross-sectional view of a surface parallel to the rolling direction and a sheet thickness direction of the base steel sheet (1). (M means at least one or both of Fe and Cr.

  • Patent number: 11954418
    Abstract: Methods and apparatuses for designing quantum circuits include generating a Pauli graph from Pauli strings in a qubit Hamiltonian. Nodes are merged in the Pauli graph, responsive to a determination that some Pauli strings are observables that are jointly measurable by entangled measurement. A quantum circuit based is generated on a merged Pauli graph that results from merging the nodes.

  • Patent number: 9446317
    Abstract: A server system refers to the login history of a registered friend player within a given period when an authenticated player has been subjected to a login process. The server system gives a bonus that corresponds to the number (login friend count) of friend users who have logged in within the given period to the authenticated player when the authenticated player has logged in.

  • Patent number: 8264472
    Abstract: A computer readable storage medium storing an information processing program causes a computer to function as display control means, coordinate detecting means, and object selecting means. The display control means displays on a display device at least a portion of a virtual world in which a plurality of objects are provided. The coordinate detecting means detects input coordinates input by the pointing device. The object selecting means, when the input coordinates indicate any of the plurality of objects, selects the indicated object as a target to be operated, and when the input coordinates indicate none of the plurality of objects, selects at least one object satisfying a predetermined condition of the plurality of objects as a target to be operated.
