A hybrid carbon fiber spun yarn comprising a core region which comprises carbon fibers as a main component, and a surrounding region which comprises carbon fibers as a main component and covers an outer peripheral surface of the core region;wherein 20% by mass or more of fibers forming the core region are long carbon fibers having a fiber length of 500 mm or longer,80% by mass ormore of fibers forming the surrounding region are short carbon fibers having a fiber length of less than 500 mm, anda mass ratio between the long carbon fibers and the short carbon fibers (long carbon fibers:short carbon fibers) is in a range of 20:80 to 80:20.

An intermediate portion of an insulating sheath of a coaxial cable is removed, and a first insulating sheath portion is drawn toward a second insulating sheath portion, so that a braid is projected into an annular shape outwardly from an interval between opposed ends of the first and second insulating sheath portions to form an annular projecting braid portion, and this annular projecting braid portion is fixed so as to be connected to a portion (that is, a braid fixing portion) of a coaxial cable shielding terminal for connection to an end portion of the coaxial cable. This connecting and fixing operation is effected by press-contacting or press-clamping.

Method for making plastic fiber for application in concrete with largest grain diameters >4 mm, with an average diameter of 0.15 to 2 mm, corresponding to approximately 160 to 28,000 dtex. Using a co-extrusion process, a bi-component fiber is formed having a central core and a casing around the central core, the central core and the casing contain different pure polymers or polymer mixtures, and then the co-extruded bi-component fiber is stretched by a factor of 5 to 15, and thereafter a structured or grooved surface is embossed onto the co-extruded stretched bi-component fiber. The embossing is performed such that a depth of the embossing is more than 10% of an average fiber diameter, and a maximal distances of structure tips within incorporated structures of the embossing in an axial direction lie in a region between 0.5 mm and 3 mm.

The invention discloses a production process for cotton paper, which comprises the following steps of: digesting long fibered wood pulp by using a hydraulic breaker, and adding chemical aids to prepare primary pulp; serially connecting a fluted disc type deflaker and a fiberizer, pulping in a semi-cohesive state at low current, wherein the pulping concentration of the fiberizer is 4.2 to 5.5 percent and the pulping ampere is 46 to 58A; compounding the pulp after the pulping is finished, adding 1 percent of brightener, filtering with a 90-mesh screen, and uniformly compounding with the pulp; and performing papermaking on the mixed pulp, drying, reeling by using a re-reeling machine, detecting broken paper in the drying and reeling procedures, digesting and defibering the detected broken paper, and refluxing the broken paper to the pulp compounding procedure. The cotton paper prepared by the process has the advantages of uniform fibrous tissues, flat and smooth paper surface and small aspect ratio.

A hybrid carbon fiber spun yarn having a core region with carbon fibers as a main component, and a surrounding region with carbon fibers as a main component and covers an outer peripheral surface of the core region. 20% by mass or more of fibers forming the core region are long carbon fibers having a fiber length of 500 mm or longer. 80% by mass or more of fibers forming the surrounding region are short carbon fibers having a fiber length of less than 500 mm. A mass ratio between the long carbon fibers and the short carbon fibers (long carbon fibers:short carbon fibers) is in a range of 20:80 to 80:20.

Provided is a connector configured so that tensile strength when an attempt is made to forcibly detach the connector from a partner connector can be enhanced. A housing includes a body portion and a fitting target portion extending to the side of fitting to the partner connector. The diameter of a side portion outer peripheral surface of the fitting target portion is, at at least part thereof, smaller than that of the body portion. A conductive shell includes a first shell and a second shell. The first shell includes a cover portion configured to cover at least part of an outer peripheral surface of the housing, an elastic arm having a free end on the side of fitting to the partner connector, and a support portion elastically connecting the cover portion and the elastic arm and configured to support the elastic arm in a cantilever manner. The elastic arm has a lock portion configured to lock fitting to the partner connector, and has a stepped portion corresponding to a stepped surface of the housing provided using a difference in the diameter. The second shell includes a portion facing the stepped portion at a position closer to the side of fitting to the partner connector than the stepped portion of the elastic arm.
