A composite stranded wire conductor includes a core bunched strand wire, first bunched strand wires mainly wound at a first main twist pitch around the core bunched strand wire, and second bunched strand wires wound at a second main twist pitch around first bunched strand wires. In the core bunched strand wire, metal wires are primary twisted in a first direction. In each of the first bunched strand wires, metal wires are primary twisted in a second direction opposite to the first direction. In each of the second bunched strand wires, metal wires are primary twisted in the first direction. A pitch ratio obtained by dividing the second main twist pitch by the first main twist pitch is 1.00 or more and 2.44 or less.

An aluminum alloy wire composed of an aluminum alloy, wherein the aluminum alloy contains more than or equal to 0.03 mass % and less than or equal to 1.5 mass % of Mg, more than or equal to 0.02 mass % and less than or equal to 2.0 mass % of Si, and a remainder of Al and an inevitable impurity, Mg/Si being more than or equal to 0.5 and less than or equal to 3.5 in mass ratio, and the aluminum alloy wire has a dynamic friction coefficient of less than or equal to 0.8.

A cable has a wire bundle composed of a number of individual wires and an insulating sheath. The wire bundle is guided along a longitudinal center axis by a shaping element in order to guide and to specify the cross-sectional shape of the wire bundle in a feeding region immediately upstream of an extruder. The shaping element rotates about the longitudinal center axis, and the insulating sheath is subsequently applied to the wire bundle by the extruder.

A wire conductor has a plurality of elemental wires made of aluminum or an aluminum alloy, which are stranded with each other and arranged, in cross-section intersecting an axial direction of the wire conductor, in which one or a plurality of virtual elemental wires are removed from an outer peripheral portion of a virtual cross-section represented by a maximum number of virtual elemental wires accommodated in a circumscribing figure approximated by a regular hexagon, the virtual elemental wires having a same diameter as the elemental wires. The wire conductor includes a plurality of slave strands, each being a strand of the plurality of elemental wires, a maximum diameter cross-sectional area ratio is 0.63 or higher that is calculated by dividing a cross-sectional area of the wire conductor by an area of a circle having a diameter equal to a maximum value of an outer diameter of the wire conductor.

A high frequency cable includes a center conductor comprising one first wire, which is located at the center of the center conductor, and a plurality of second wires, which are located around that one first wire, and the one first wire and the plurality of second wires are stranded together. Respective outer peripheral surfaces of the plurality of second wires constitute a substantially continuous circular peripheral surface as an outer peripheral surface of the center conductor.

Highly uniform and thin silver nanowires are described having average diameters below 20 nm and a small standard deviation of the diameters. The silver nanowires have a high aspect ratio. The silver nanowires can be characterized by a small number of nanowires having a diameter greater than 18 nm as well as with a blue shifted narrow absorption spectrum in a dilute solution. Methods are described to allow for the synthesis of the narrow uniform silver nanowires. Transparent conductive films formed from the thin, uniform silver nanowires can have very low levels of haze and low values of L*, the diffusive luminosity, such that the transparent conductive films can provide little alteration of the appearance of a black background.

A braid processing device trims an end portion of an exposed braid of a braid-shielded cable including a cable center portion (e.g., two insulated wires), a braid that covers an outer circumferential surface of the cable center portion, and a sheath that covers an outer circumferential surface of the braid, the exposed braid being exposed from the sheath. The braid processing device includes a braid raising mechanism that raises the exposed braid from the cable center portion toward an outer circumferential side, and a shearing mechanism. The shearing mechanism includes an outer blade that has an annular outer cutting edge, an inner blade that has an annular inner cutting edge, the annular outer cutting edge and the annular inner cutting edge being capable of shearing the exposed braid therebetween, and a blade driving portion that relatively moves the inner blade toward the annular outer cutting edge.
