A flat wiring member includes a plurality of rectangular enamel coated wires arranged in the form of a flat plate, a wiring stem portion that the rectangular enamel coated wires are arranged in parallel to each other and adjacent ones of the rectangular enamel coated wires are bonded to each other at a surface of an enamel coat layer thereof, and a wiring branch portion with the rectangular enamel coated wires bent so as to branch off from the wiring stem portion.

Flat wiring member and method of manufacturing the same

A wiring material includes conductors, each of which has a cross section having a thickness and a width not less than the thickness, a trunk portion in which the conductors are spaced parallel in a direction of the width thereof, a branch portion in which each conductor is bent and branched from the trunk portion in the direction of the width or in a direction that intersects the direction of the width, and a covering member for covering the trunk portion and the branch portion to expose both ends of the conductors.

Wiring material, method for fabricating the same, and secondary battery device and electronic equipment using the same

A method is for producing an electrode terminal connector for electrically connecting together a positive terminal and a negative terminal of mutually dissimilar metals. The method includes pressing a first plate of a similar metal to the positive terminal to form a mounting hole in the first plate, pressing a second plate of a similar metal to the negative terminal to form a metallic member which is larger in diameter than the mounting hole, and inserting the metallic member into the mounting hole by press fitting to join the first plate and the metallic member together. The method further includes providing the metallic member with an intervening layer of metal having an ionization tendency between an ionization tendency of metal constituting the first plate and an ionization tendency of metal constituting the second plate, and the first plate and the metallic member are joined together via the intervening layer.

Electrode terminal connector producing method

A conductor for a flexible substrate, used for a flexible flat cable or disposed inside a flexible printed-circuit board, according to the present invention comprises: a base conductor made of Cu or Cu-alloy; a plating film made of Sn or Sn-alloy formed on a surface of the base conductor; and a surface oxide film formed on a surface of the plating film, in which the surface oxide film includes oxide of an element other than Sn or a mixture of Sn oxide and oxide of an element other than Sn.

A vehicle electrical conduction path includes plural power cables, a braided shield which bundles and shields the plural power cables, a control cable, a metallic pipe which accommodates the control cable separately from the plural power cables, and a flexible resin tube which covers a periphery of the metallic pipe and the plural power cables bundled with the braided shield and arranged along the metallic pipe.

Vehicle electrical conduction path

An antenna having an antenna element bent in a predetermined shape. The antenna element has a plurality of line conductors that are arranged in parallel and are sandwiched by two insulation films. A method of making an antenna has the steps of: arranging in parallel a plurality of line conductors, each of which having a width of 0.04 mm or less, at intervals of 10 times or more the width of each of the line conductors; discharging continuously the plurality of line conductors such that visibility of the line conductors is reduced; and sandwiching continuously the discharged line conductors by planar transparent insulation films with a sticking or adhesion layer to have an antenna element.

Antenna and method of making the same

An electromagnetic shielding filter has two transparent boards and a conductive mesh with plural wires, where the conductive mesh is sandwiched between the two transparent boards. The plural wires are formed of a Cu&#x2014;Sn&#x2014;In alloy or a Cu&#x2014;Ag alloy.

Electromagnetic shielding filter

An antenna according to the present invention comprises: a plurality of parallel disposed linear conductors; two insulating films between which the plurality of linear conductors are sandwiched; at least one cut portion formed in at least one of the plurality of linear conductors; and a feed point connected to at least one of the plurality of linear conductors. With this configuration, the segment of the linear conductor connected to the feed point provides a driven element, while the other end of the linear conductor opposite to the feed point connected end is electrically open so that the segment of the linear conductor extending beyond the cut portion provides a parasitic element.

Antenna and manufacturing method thereof

A flat cable conductor has: a conductor made of copper or a copper alloy; a first plating film made of tin and/or a tin-copper alloy, the first plating film being formed around the conductor; and a second plating film made of an alloy of tin and a third element selected from Au, Ag, Ni, Ge, Zn and Bi, the second plating film being formed around the first plating film. The third element has a concentration of 0.01 or more and 80 or less wt % at an outer surface of the second plating film.
