A wave power generation device of the present invention includes: a buoy floating on the sea; a power generator generating electrical energy or hydraulic energy; a power transmitter connecting the buoy and the power generator to each other; and a wire having a first end and a second end connected to the buoy or the power transmitter and changing in tension by motions of the buoy.

A high-strength fibre rope (1) comprising a rope core as well as a sheathing indicating optical wear, wherein the sheathing comprises a sheath layer (2) made up of textile subunits (3, 4) of a first hierarchy level. An outermost sheath layer (2) is provided, wherein textile subunits (3, 4) of said outermost sheath layer of the first hierarchy level differ from each other in terms of their textile structure, and/or an outermost sheath layer and a further sheath layer underneath said outermost sheath layer are provided, and wherein the textile subunits of the first hierarchy level of said outermost sheath layer differ in their textile structure from that of said further sheath layer. The textile subunits of a lowermost hierarchy level of the rope are neither dispersed in a resin matrix in the outermost sheath layer nor in the further sheath layer arranged underneath the outermost sheath layer.

There is provided a high-tensile synthetic fiber rope having a low percentage elongation, the rope dramatically improving the strength utilization rate of the tensile strength of the synthetic fibers, and ensuring the percentage elongation approximately the same as the percentage elongation of the synthetic fibers used in the rope. The synthetic fiber rope includes a plurality of strands twisted or braided together, each of the strands including: a tubular woven fabric woven with warp and weft yarns made of synthetic fibers; and a core material disposed in the tubular woven fabric, the core material being constituted by a plurality of parallel-bundled yarns made of the synthetic fibers in the tubular woven fabric.

Provided herein is an electrodeposition apparatus for producing long polymeric threads, yarns, or ropes. A method of preparing long polymeric threads, yarns or ropes also is provided.

A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.
