  • Publication number: 20170057418
    Abstract: A hook case has a base; boxes which are formed on the back side of the base; and shaft holding members which are placed on the horizontal sides of the box. A hook has a body, a tang for hanging up baggage; and a hook shaft, and is capable of rotating between a housed position in the box and an in-use position in which the tang extends out of the box. The hook shafts have a first groove and a second groove. The shaft holding members of the case include case bearings which are provided on the back side of the base and which hold the hook shafts; and elastic tabs which engage in the first groove in the housed position, and in the second groove in the in-use position.

  • Patent number: 9121085
    Abstract: A method for manufacturing a composite metal alloy. An Mg material as an alloy base material and a carbon nanomaterial are mixed together to obtain a mixture in which the Mg material is covered with particles of the carbon nanomaterial. The mixture of the Mg material and carbon nanomaterial are sintered to obtain an Mg sintered compact including the carbon nanomaterial. The Mg sintered compact including the carbon nanomaterial is dissolved to obtain a melt of the composite metal alloy.

  • Patent number: 8424173
    Abstract: A spacer clip includes a flange, a shank extending from the flange that can be inserted into a through in a member being attached to, and legs extending from the end part of the shank, connected by hinges to the shank end part so as that they can pivot from an initial attitude to a clamping attitude wherein they are substantially parallel to the flange. Levers extend from root portions of the legs toward the tip ends of the legs so that they can pivot together with the legs. The legs have leg-side pawls in the portions thereof adjacent to the shank end part, which extend to the flange side when the legs are in the clamping attitude; the flange has flange-side pawls for engaging the leg-side pawls and maintaining the legs in the clamping attitude; and slits are formed on either side of the flange-side pawls.

  • Patent number: 8171979
    Abstract: A method for producing a carbon nanocomposite metal material with increased carbon nanomaterial dispersibility and increased binding between carbon nanomaterial and matrix metal stock is disclosed. A preform obtained by mixing a matrix metal stock and microparticulate-coated carbon nanomaterial without the need for a dispersant and then compacting the material is maintained for a set time period at a temperature that is at or above the melting point of the matrix metal stock. In this state, the heat-treated body is reduced to a temperature that allows hot working, and a compacting treatment is performed.

  • Patent number: 8012275
    Abstract: In a method for manufacturing a composite-metal-forming material, heating a metal material a Mg alloy or an Al alloy is heated to a temperature in a region where a solid and a liquid are both present to thereby yield a semi-molten metal material in a semi-molten state. An additive material is introduced to the semi-molten metal material and kneading is performed to obtain a composite metal material. The composite metal material is heated to a solution temperature of the metal material and a solution treatment is performed to thereby yield a composite-metal-forming material.
