Abstract: A method for producing an optical fiber cable which improves stability by attaching an Aramid yarn near the core in parallel to an axial direction of the optical cable and solves structural problems of the cable by soaking an Aramid yarn into an epoxy resin is disclosed. This optical cable producing method uses a tensile material for improvement of tensile property, and includes the steps of soaking the tensile material into an epoxy resin, and attaching the tensile material to the optical cable in parallel to the axial direction of the optical cable.

Abstract: A design system associated with prestressed concrete cylinder pipe (PCCP) using a graphic user interface (GUI), which is capable of carrying out, in an integrated fashion, a variety of operations such as operations for the design of embedded-cylinder pipe (ECP), lined-cylinder pipes (LCP), and fittings, computer-aided drawing (CAD) interfaces, operations for quantity calculation, operations for inquiry to a Database, and operations for a demo presentation, in a GUI environment allowing for the easy use of the design system by the user. In accordance with this operating method, it is possible to not only reduce the time taken to design ECP, LCP, and fittings, but also to allow the user to achieve such a design even when he has no theoretical knowledge of that design while only having knowledge of data inputting and outputting.

Abstract: The present invention relates to a method for manufacturing a nickel-metallic hydride electrode. This invention is characterized in that rare earth-nickel-hydrogen-stored alloy powder is molded by plating it with copper without electrolysis, so that mechanical strength, electric conductivity and reaction velocity can be improved by increasing the amount of plating the surface of a molded electrode with copper.
