Abstract:
Seilartiges Gebilde als Seil, Saite oder Kordel, bestehend aus einer Vielzahl von Fasern von denen ein Anteil von mindestens 25 % als mit Nanoröhrchen verstärkte Fasern vorliegen. Die verstärkten Fasern weisen eine Festigkeit grösser als 38 cN/dtex auf und die damit gefertigten seilartigen Gebilde übertreffen die Reissfestigkeit üblicher Seile, Saiten oder Kordeln. Die seilartigen Gebilde weisen eine Reissdehnung von weniger als 2,5 %, eine Schmelztemperatur grösser als 150 °C und einen Creep kleiner als 0,9 % auf. Verwendungen finden sich im Segel- und Wassersport, im Flug-, Tennis- und Bergsport und ferner als Lift- und Skiliftkabel und als Sesselbahn- und Kabinenbahnkabel.
Abstract:
A flexible intravascular guidewire comprises a plurality of filaments braided together and drawn through a die to a reduced cross-sectional area of circular shape. Preferably, one or more of the filaments is coated with a radiopaque material prior to drawing it through the die. According to a preferred embodiment, each of the filaments is made from the same metallic material; alternatively, the filament material may differ, e.g., to provide flexibility and torsional stiffness characteristics which are unachievable in a metal monofilament, or in a multifilament wire of the same filament materials.

PROBLEM TO BE SOLVED: To provide a pneumatic radial tire 2 capable of attaining weight reduction without impairing fitting property. SOLUTION: The tire 2 is provided with a pair of beads 8. Each of both beads 8 is provided with a core 24. The core 24 is formed by winding a strand 38 obtained by covering a topping rubber 44 on a hybrid cord 42 in a peripheral direction a plurality of times. The hybrid cord 42 is provided with: a wire 46 of which the material is steel; and a knitted layer 48 for covering the wire 46. The knitted layer 48 is constituted by plain stitch of a filament comprising an aramid fiber. Since the hybrid cord 42 having the wire 46 has appropriate rigidity, the tire 2 is excellent in the fitting property. The knitted layer 48 comprising the aramid fiber contributes to reduction of an amount of use of the wire 46. The tire 2 can attain light weight without impairing the fitting property.

Abstract:
PROBLEM TO BE SOLVED: To provide lightweight blend fiber excellent in shading tendency, lightweightness and physical properties including boiling water shrinkage and residual elongation and also having high mechanical strength. SOLUTION: The lightweight blend fiber with high shading tendency is made from a fiber-forming thermoplastic polymer A as the main component, a thermoplastic polymer B having no maleimide structure in the molecular skeleton, and a light shading agent. The blend fiber has numerous microvoids, being 2-30% in boiling water shrinkage represented by the formula(1):S=(1-L/L 0 )×100( wherein, S is boiling water shrinkage(%); L 0 is the original length of a hank taken on a bobbin, measured at an initial load of 0.09 cN/dtex; and L is the length of the hank, measured at an initial load of 0.09 cN/dtex after air-dried, after the above hank is treated in boiling water for 15 min under no substantial load ) and 5-50% in residual elongation.

Abstract:
PROBLEM TO BE SOLVED: To provide a high-strength rope remarkably improving defects such as fibrillation, component interfacial peeling and water absorption in a conventional rope and having excellent operation stability. SOLUTION: This high-strength rope is composed of a sea-island type conjugated fiber comprising an island component composed of a liquid crystal polyester and a sea component composed of a flexible thermoplastic polymer. The high-strength rope is composed by regulating the island component diameter (r) based on the fiber diameter (R) to r/R≤0.3. COPYRIGHT: (C)2004,JPO
