Title: Manufacture of composite flat rectangular wire
Inventor: SATO JIRO
IPC: H01B13/00
Filed: 1989-02-16
Abstract: PURPOSE:To render the cross-sectional shape of a core satisfactory so as to prevent an occurrence, such as abnormal deviation in the thickness of a covering material, or the like by coreving the core with the covering material having its deformation resistance smaller than that of the core as well as its low melting point, rolling the covered core into a rectangular shape and heating the resultant product. CONSTITUTION:A cross-sectionally circular round-wire core 1 is covered with a covering material 2 to manufacture a cross-sectionally circular composite bus bar, and the bus bar is then rolled to a desired thickness to be processed into a flat rectangular wire. Subsequently, an intermediate product formed with protruding portions 3 is heated to a temperature a little higher than the melting point of the covering material 2 for melting down the covering material 2 only. Each of the protruding portions 3 is therefore attracted to and coalesced with the side of the covering material 2, so that a composite flat rectangular wire can be obtained with the covering material 2 of uniform thickness. Since no mechanical means is employed in removing the protruding portions 3, there may be no problems, such as sagging due to its processing, causing cut pieces to remain and cling to the product, and the like. Thus, any possibility of deviation in the thickness of the covering material covered is avoided to provide improvement in the quality of the wire.

Title: Device for correcting dropping condition of raw material on distributing chute
Inventor: YOSHIDA SHIGEKI
IPC: C21B7/20
Filed: 1992-01-28
Abstract: PURPOSE:To suitably control raw material distribution after charging even in the case a raw material does not drop in a vertical direction on a circulating distributing chute while charging the raw material. CONSTITUTION:The positions of flow rate adjusting gates 12a, 12b fitted to furnace top bunkers 10a, 10b are not above the raw material dropping hole 17a of the vertical chute 17.
