Abstract:
A steel cord intended for use to reinforce rubber products is produced by drawing, into a steel filament of 0.10 to 0.40 mm in diameter and more than 3,000 N/mm 2 in strength, a wire rod having a carbon content of more than 0.70% by weight, and twisting a plurality of such steel filaments together. Also a pneumatic tire is provided which employs in at least a portion of a reinforcing member thereof the steel cord improved in corrosion resistance and having an R 1 /R 0 ratio x 100 which is less than 100, where R 0 is the radius of spiral curvature of the spiraled steel filament resulting from untwisting said steel cord and R 1 is the radius of spiral curvature of said steel filament of which the surface layer inside the spiral is removed by dissolving.

Abstract:
An armored optical cable (10) and process of manufacturing. The armored optical cable (10) exhibits minimal inelastic elongation is response to tension at elevated temperatures and is capable of withstanding harsh ambient conditions. The armored optical cable (10) is fabricated in a unitary operation with a central bundle (30) of one handedness surrounded by at least one outer armor layer (32) of opposite handedness substantially torque balanced to the handedness of the central bundle (30).

Abstract:
PURPOSE: High tensile steel cord structure for a tire is provided to minimize the movement of the steel cord by sticking rubber to the steel cord firmly with infiltrating rubber to the steel cord, and to improve endurance by restricting corrosion with preventing the cord from being contacted to water or oxygen. CONSTITUTION: A steel cord of a tire is composed of a core filament and a strand filament. The core filament and the strand filament are twisted conversely, and the pitch as the twisting period of the core filament is different from the pitch of the strand filament. The rate of the core pitch to the strand pitch is formed to be within the range of 0.5-0.94. The steel cord is formed with adding 3 times core filament diameter to 8 times strand filament diameter. The rubber is stuck to the steel cord with twisting the steel cord and the rubber conversely.
Abstract:
PURPOSE: A steel cord of tires of a truck and a bus for high load is provided, which is characterized by increasing excellent breaking property because of increasing rubber penetrating property, having no a lean of filament and no untwist of a cross section in a cord layer by removing the warp, and improving durability. CONSTITUTION: On the belts of a truck tire and a bus tire, the cord having a structure of 3d+8d+13d(d:filament diameter) is used. A twisting direction of the cord is SZS. A twisting length of the cord is 4-6mm/10-15mm/18-24mm.
