摘要： PROBLEM TO BE SOLVED: To reduce the groove slope in a spacer cross section regardless of the cross-sectional structure of the spacer and the inversion pitch and to reduce the fluctuation of the groove volume in the longitudinal direction by making the inclination index to be more than a prescribed value and suppressing the groove tilt angle in the spacer cross section to be less than a specific value. SOLUTION: Plural recessed shape optical fiber housing grooves 20 are provided on the outer peripheral edge of a main body coating layer 16 of the spacer at intervals in the peripheral direction. The grooves 20 are separated by ribs 22, provided along the longitudinal direction of the layer 16 and formed in a so-called SZ helical shape in which a prescribed strand pitch and a lead angle are provided and the helical direction is reversed for every prescribed pitch. Let a rib inclination index (F) = one rib cross-sectional area (S) ×a rib center of gravity distance (XG) × a helical advance angle (α)/a minimum rib thickness (T), the index F is set to be more than a prescribed value and the groove inclination angle in the spacer cross section is made less than 10 deg.. Thereby, the fluctuation of the effective cross section of the grooves is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a coaxial cable excellent in closely contacting property, and a manufacturing method of the same. SOLUTION: The coaxial cable 10 is composed of center conductors 12, an insulation cove layer 14, shield conductors 16, and a protection cover layer 18. The cover layer 14 formed so as to cover the outer periphery of the conductors 12 has a ring-shaped part 20 covering the outer periphery of the conductors 12 and three column-shaped parts 22 radially extended from the sing-shaped part 20a in the direction of diameter. The shield conductor 16 is composed of hollow and compressed strand wire. The strand wire is formed into hollow-shape by passing a plurality of elemental wires 26 through a compression dice while twisting them in one direction. At this time, as a part of outer periphery of the elemental wires 26 is deformed and twisted, shield wires tightly contact with each other like a stone fence, and made to have a stable structure (arch structure). At the same time, a part of the insulation cover layer 14 contacting the shield conductor 16 is turned into a deformation part 28 tightly contacting the shield conductor 16 along the inner face shape thereof.

SOLUTION: A creel 1, an extruder 2, a cooling tank 3, a heating device 4, a cooling sizing 5 and a taking-over machine 6 are used. A kneaded mixture of a foaming agent and a molten thermoplastic resin is continuously extruded to the outer periphery of a tensile force member A from the cap part of the extruder 2 and the extruded mixture is passed through the cooling tank 3 to be cooled and solidified to obtain an intermediate foamed linear article C wherein a thermoplastic resin foamed layer B is formed on the outer periphery of the tensile force member A. The linear article C is heated in the heating tank 4 to melt the outermost resin part of the intermediate foamed linear article C. Next, the linear article C is introduced into the cooling sizing 5 to be sized and cooled so as to become an outer diameter dimension below the outer diameter dimension d2 of a final foamed linear article E.
