Abstract: Male terminals 83 are respectively provided in terminal attachment portions 82 formed on a flange unit 7. Female terminals 84 and grommets 85 are provided for a harness 17. A seal lip portion 86 to be fitted into each of the terminal attachment portions 82 is formed on each of the grommets 85. In the cylindrical terminal attachment portions 82, the male terminals 83 are individually accommodated while being electrically insulated from each other. The terminal attachment portions 82 are arranged alternately in two rows so that a line segment obtained by connecting the respective centers of openings of the terminal attachment portions is a polygonal line. The openings 87 are arranged to form the Olympic symbol. At a fore-end of each of the terminal attachment portions 82, slits 89 are provided. Owing to the slits 89, the opening 87 is likely to be enlarged when the rubber grommet 85 is inserted therethrough. As a result, the placement of the rubber grommet 85 is facilitated.

Abstract: A polyethylene fiber having high strength and extremely high productivity is difficult to obtain by conventional gel spinning methods. This high strength polyethylene fiber includes an ultrahigh molecular weight polyethylene resin having an intrinsic viscosity of 8 dL/g or more and contains a poor solvent in an amount of 10 ppm or more with respect to the resin. This high strength polyethylene fiber may also contain an ultrahigh molecular weight polyethylene resin having an intrinsic viscosity of 8 dL/g or more in which the resin contains a non-solvent in which the resin is insoluble in an amount of 10 ppm or more.

Abstract: A polyethylene fiber having high strength, which was not easily obtained by methods such as the conventional gel spinning method, includes crystals derived from a monoclinic crystal having a size of 9 nm or more. The tensile strength of the fiber can be 30 cN/dtex or more. This high strength polyethylene fiber is produced by mixing an ultrahigh molecular weight polyethylene with a mixed solvent of a good solvent for polyethylene and a poor solvent for polyethylene to form a polyethylene dope, extruding the dope through an orifice, cooling the extruded dope, and drawing it into a filament yarn.

Abstract: PURPOSE: To provide a novel high strength polyethylene multifilament which consists of a plurality of filaments having high strengths and uniform internal structures, and showing a narrow variation in the strengths of the monofilaments, and which has been difficult to be provided by the conventional gel spinning method. SOLUTION: A high strength polyethylene multifilament consisting of a plurality of filaments which are characterized in that the crystal size of monoclinic crystal is 9 nm or less; the stress Raman shift factor is ?5.0 cm?1/(cN/dTex) or more; the average strength is 20 CN/dTex or higher; the knot strength retention of each monofilament is 40% or higher; CV indicating a variation in the strengths of the monofilaments is 25% or lower; the elongation at break is from 2.5% inclusive to 6.0% inclusive; the fineness of each filament is 10 dTex or less; and the melting point of the filaments is 145° C. or higher.
