  • Publication number: 20190255618
    Abstract: A method of processing a rare earth magnet comprises: a step of irradiating an R-T-B-based rare earth magnet with laser light to process; and a step of performing heat treatment on the magnet after the irradiating. The heat treatment includes: a step A of bringing the temperature of the magnet to 400° C. or less, a step B of holding the magnet at a temperature T1 in a range of 400 to 700° C. after the step A, and a step C of bringing the temperature of the magnet to less than 400° C. after the step B. The temperature of the magnet is made not to exceed 700° C. between the step A and the step B. The temperature of the magnet is made not to exceed 700° C. between the step B and the step C. A step of setting the magnet at a temperature higher than 700° C. after the step C is not included.

  • Patent number: 8253522
    Abstract: A coil component includes a bobbin having a core part and a flange. The flange has a first surface on a first side and a second surface on a second side. The first surface of the flange is attached to an axial end of the core part. An end of a wire is electrically connected to a metallic terminal of a terminal-mounting member disposed on the flange. The flange is formed with a notch at a position near the terminal-mounting member, and the notch extends from a peripheral edge of the flange toward the core part. A segment of the wire near the end thereof extends from the second side to the first side of the flange through the notch and further to the core part, and this segment of the wire is hooked around the wire-supporting member in the notch.

  • Patent number: 7471179
    Abstract: Each terminal electrode has a welded portion at which each end portion of a conducting wire is electrically connected to each terminal electrode upon laser welding. The conducting wire is provided with an insulation coating. The insulation layer has an edge on the surface of the conducting wire. Each welded portion has a bulge portion bulging in a direction away from the core and in contact with only the edge of the insulation coating. The edge determines a shape position and size of a melted bulge portion.

  • Patent number: 7411478
    Abstract: A coil component including a connection part not excessively welded to a terminal electrode. End portion of a conducting wire of a common mode filter is laser-welded, while being held by a holding piece and a surface of the terminal electrode. A portion melted by laser-welding includes a bulge portion which bulges in a direction away from a core. There is provided a lower insulation covering portion between a foundation and the portion corresponding to the end portion of the conducting wire. For the bulge portion, the lower insulation covering portion is provided only between the foundation and the portion corresponding to the end portion of the conducting wire, thereby preventing excessive welding to a terminal electrode.
