A method of fabricating a case for a portable electronic device includes: preparing a case preform; processing the inner surface of the case preform using a laser; and surface-treating the outer surface of the case preform, wherein the outer surface of the case preform shows fine prominences and depressions formed by the surface-treating of the outer surface of the case preform, and patterns formed by processing the inner surface of the case preform appear bumpily on the outer surface of the case preform.

Method of fabricating case for portable electronic device

A coating composition for a soft feel coating on portable terminals and electronic instruments having excellent discoloration resistance, heat resistance, yellowing resistance and anti-fouling properties is disclosed. The coating composition includes an oligomer composition obtained by blending polybutadiene polyol and polyolefinic acid, and various additives added to the oligomer composition. The coating composition is coated onto surfaces of portable terminals and electronic instruments.

Coating composition for a soft feel coating on portable terminals and electronic instruments

An optical fiber cable includes a plurality of loose tubes and an outer jacket for binding the loose tubes is disclosed. Each of the plurality of loose tube includes one or more optical fibers; an inner jacket for binding the optical fibers; and an antistatic fluid applied between the optical fibers to prevent or reduce the generation of static electricity between the optical fibers.

Optical fiber cable

An optical fiber cable suitable installation using an air-blown method is disclosed. The optical fiber cable has a center tensile member located at a center of the optical fiber cable to provide tension-resistant force, at least three loose tubes each of which includes at least one optical signal transmitting medium, and located to surround a peripheral portion of the center tensile member, a binder surrounding the loose tubes to maintain an alignment pattern of the loose tubes, and a sheath located at an outermost portion of the optical fiber cable. The optical fiber cable has a polygonal sectional shape having smooth edges.

Optical fiber cable suitable for installation using an air-blown installation method

Disclosed is an air-blown fiber-optic cable including: a central tensile member which is located axially through the center of the optic cable and provides a tension-resistant force; a plurality of loose tubes wound around the tensile member, each tube housing a plurality of optic fibers therein; aramid yarns for binding the loose tubes; and an outer sheath disposed on the outermost part of the optic cable to protect the interior thereof from the exterior environment.
