摘要： Thermoplastic synthetic polymer fibers having powder of metal attached to the surface of the fibers are subjected to a treatment for increasing the oxidation number of said metal from zero to a plus value, that is, oxidation in a broad sense. The resulting conductive synthetic fibers support a layer of a compound of the metal, i.e. an oxidized product of the metal in a broad sense, firmly and undetchably thereon, and have as low an electric resistivity as 10.sup.5 .OMEGA./cm or less. The conductive fibers can be blended to ordinary synthetic fibers to improve their antistatic property, or can be substituted for expensive metal fibers. The thermoplastic synthetic polymer fibers are sheath-core fibers wherein the sheath has a lower melting point than the core.

摘要： Synthetic fibers capable of absorbing aqueous medium are manufactured by simultaneously extruding the fiber material and a second material in a core and sheath arrangement. Turbulence is produced in the zone where these two materials combine which results in undulations in their cross-sections. The second material is then dissolved away with a solvent to leave a fiber with an undulating surface. When the second material is extruded as the core, the fiber is hollow with undulations on the inside while when the second material is extruded as the sheath the solid fiber has an undulating outer surface.

摘要： A vanity case includes a receptacle and a cover hinged with each other at rear ends thereof, the cover being maintained in a closed position by engagement between latch tongues formed on the receptacle and the cover. The receptacle is formed at the front end with a recess within which is slidably disposed a push piece having a front wall and an arm integrally formed with the front wall through a thin flexible section which permits the arm to tilt relative to the front wall. The upper end of the arm is positioned closely adjacent the lower surface of the cover, and the rear end of the arm abuts against the inner wall defining the recess and, upon rearward movement of the push piece, slides on the inner wall upwardly to tilt the arm whereby the upper end of the arm forces the cover in upward and forward directions to release the engagement of the latch tongues.
