A three-dimensional wire bending jig is disclosed. The jig includes a tubular body having an outer diameter and an inner diameter. The body has a plurality of through-openings formed therein. The plurality of through-openings form a repeating pattern around the body. A kit including the jig, a plurality of pins, and a retaining member is also provided.

A technique for depositing fiber-reinforced thermoplastic filament in an arc is disclosed that mitigates the centripetal forces that arise in the prior art. In accordance with the illustrative embodiment, the centripetal forces are ameliorated by twisting the filament while depositing it in an arc.

The present invention relates to novel aqueous polyurethane dispersions produced using at least two poly(tetramethylene glycol) polyether polyols with different average molar masses and at least two different polyisocyanate components.

An object of the present invention is to provide an antiviral fiber assembly in which an antiviral agent is retained with chemical stability over a long period of time, and which is gentle to the human body. A further object of the present invention is to provide a fiber assembly with cellulose sulfate that can exhibit sufficient antiviral activity over a long period of time. Further, another object of the present invention is to provide a textile product obtained using such a fiber assembly. The present invention provides a fiber assembly with cellulose sulfate, wherein the hyaluronidase inhibitory activity is 50% or higher; and a process for producing a fiber assembly with cellulose sulfate, including treating a fiber assembly with an aqueous cellulose sulfate solution and drying, then treating the same with a pH buffer solution and drying.

Optical fiber amplifiers are disclosed that utilize optic fibers encapsulated by graphene as the gain medium. Doped fiber optic amplifiers utilize optic fibers that are doped with a rare earth element for the gain medium that is encapsulated by graphene. Raman fiber optic amplifiers utilize an undoped fiber as the gain medium that is encapsulated by graphene.
