  • Patent number: 7964803
    Abstract: A magnetic shield structure having openings, the structure comprising a plurality of similar magnetic blind bodies 2, each blind body 2 having an imaginary blind core plane F and a plurality of magnetic material slats 1 being spaced from each other by a distance d required for magnetic shielding, each slat 1 intersecting the blind core plane F at a longitudinal central axis C thereof, the longitudinal central axes of the slats are oriented substantially in parallel to each other on the blind core plane F. The blind bodies 2a, 2b are coupled in a row by serially coupling each slat 1 in each blind body 2a to a corresponding slat 1 of adjacent blind body 2b through overlapping or abutting of slat terminal portions, whereby the blind core planes Fa, Fb of the blind bodies 2a, 2b are so coupled as to define a successive magnetic shield plane, and spaces d between adjacent slats 1 in each blind body 2a, 2b form openings in the magnetic shield structure.

  • Patent number: 6387522
    Abstract: The present invention provides a grain-oriented electrical steel sheet, for a low noise transformer, capable of reducing higher harmonics which are highly audible and lowering noise effectively, and relates to a grain-oriented electrical steel sheet for a low noise transformer, characterized by imposing a film tension of 0.5 to 6.0 MPa on the surface by coating or a method corresponding thereto, without forming a glass film on the grain-oriented electrical steel sheet or, if a glass film is formed, after removing the glass film by an arbitrary method.

  • Patent number: 6368424
    Abstract: A grain-oriented electrical steel sheet with improved magnetic properties is achieved by a reduced 180° C. magnetic wall spacing with pulse laser light irradiation. The rolling direction width of the periodic closure domain generated by laser irradiation is no greater than 150 &mgr;m. The depth of the periodic closure domain in the direction of the steel sheet thickness is at least 30 &mgr;m. The product of the length of the periodic closure domain in the rolling direction width direction multiplied by the length of the depth of the periodic closure domain in the direction of the steel sheet thickness is at least 4500 &mgr;m2. The magnetostriction with materials of 0.23 mm sheet thickness (&lgr;19 p-p compression) is no greater than 0.9×10−6, and magnetostriction with materials of 0.27 mm sheet thickness (&lgr;19 p-p compression) is no greater than 1.3×10−6.

  • Patent number: 4290829
    Abstract: A box annealed steel strip having small strains is produced by: pretreating a steel strip in such a manner that a side edge portion thereof is thermally treated under a different condition from another condition under which the remaining portion, including an opposite side edge, thereof is thermally treated, so as to cause the longitudinal length of the side edge portion to be different from that of the remaining portion; winding the pretreated steel strip under tension to form a coil in such a manner that greater tensile stresses are produced in the other one of the side edge portion and the remaining portion, which one has a longitudinal length smaller than that of the other one, than those produced in the other one; placing the coil on a base plate so that a side edge included in the portion having the greater stresses comes into contact with the base plate, and; box annealing the coil on the base plate in a box annealing furnace.
