  • Patent number: 10968620
    Abstract: A sandwich structure includes two face plates, with a lattice structure between the plates, and with hard points at selected locations. The face plates, and the lattice structure with its hard points, may all be made as a single continuous piece by an additive manufacturing process. The hard points may be strengthened and/or stiffened areas of the lattice that may be used for connecting fasteners, or for other purposes. The hard points may be located at the junction between the lattice and one of the faces, and may be a locally thickened portion on one of the faces, for example being a cylindrical or parallelepiped protrusion out from the face. The hard points may serve the purpose of a built-in nut plate, such as themselves containing threaded holes, or by having a threaded inserts put into holes or recesses in the hard points.

  • Patent number: 10882793
    Abstract: A ferrite sheet manufacturing method according to the present invention includes (1) stacking a plurality of molded ferrite sheets to prepare a ferrite stack having gas discharge passages between adjacent molded ferrite sheets, and (2) sintering the ferrite stack. According to the present invention, productivity can be increased, and manufacturing costs can be reduced. In addition, a gas generated during combustion of a binder can be discharged using a gas discharge passage between repeatedly uneven portions disposed in one direction, thereby preventing wrinkles or waviness generated in a peripheral portion of a ferrite sheet. Furthermore, since it is possible to improve durability and reliability of an electromagnetic wave shielding material manufactured using the ferrite sheet, the ferrite sheet can be applied to various electronic products.

  • Patent number: 10836139
    Abstract: A three-layered composite has the form of a metal sheet or strip. A first core layer having a first steel material forms a composite central layer. A second plating layer has a second steel material different from the first steel material. A third plating layer has a third steel material different from the first steel material. The second and third plating layers are roll-plated onto opposite sides of the core layer and form the outer two composite layers. While the composite thickness remains the same, the first steel material thickness varies over the width of the composite. The first steel material extends, and can be press-hardened, continuously over the entire width of the composite material. The second and/or third steel materials, in the plating-layer thickness, follow the variation of the core-layer thickness in opposite directions and have a carbon content lower than that of the first steel material.
