The present invention provides a heat emitting body including a) a transparent substrate, and b) a conductive heat emitting pattern having a boundary line shape of figures forming a Voronoi diagram and an intersection point part of boundary lines, at which two or more boundary lines meet each other, forming a curve on at least one side of the transparent substrate, and a method for manufacturing the same.

Heating element and a manufacturing method thereof

The present invention relates to a belt-shaped metal nanostructure in which a wide surface area of catalytically active material can be realized even by a relatively small amount thereof so that it shows an excellent catalytic activity, and a method for preparing same.

Belt-shaped metal nanostructure and method for preparing same

A portable terminal with a speaker device includes a body housing, and a speaker module provided in the body housing and slidably retracted or extracted into/from the body housing. The speaker module includes a speaker housing slidably settled in the body housing, guide rails provided in the body housing, for sliding the speaker housing, at least one guide protrusion provided on the speaker housing and slidably engaged with the guide rails, and a moving member protruding from the speaker housing to an outside of the body housing, for retracting or extracting the speaker housing into/from the body housing.

Portable terminal with speaker device

A micro coaxial cable with a high bending performance, having an inner conductor; an insulating layer configured to surround the inner conductor, and a helical winding conductor configured to surround the insulating layer and having an elongation of 1.5 to 4% and a pitch of 3.0 to 5.0 mm.

Micro coaxial cable for high bending performance

A keypad assembly mounted in a portable terminal is disclosed. The keypad assembly has a window keypad including a display window disposed on a front face of the portable terminal. A keypad top is integrally molded with the display window and simultaneously assembled on the front face of the portable terminal, thereby providing an easier assembly than known heretofore, as two parts can be assembled at the same time and additionally provide an elegant exterior front face.

A coaxial cable includes a central conductor made of cylindrical conductive material with conductivity greater than 100% and smaller than 104%, the central conductor having a thickness greater than 0.1 mm and smaller than 0.5 mm; a dielectric layer surrounding the central conductor and made of insulating material; an outer conductor surrounding the dielectric layer and made of conductive material with conductivity greater than 97% and smaller than 105% and a thickness greater than 0.24 mm and smaller than 0.35 mm; and an outer jacket surrounding the outer conductor. This coaxial cable allows stable transmission of signal even at a high frequency.

Coaxial cable

A foam coaxial cable includes a central conductor; an inner skin layer surrounding the central conductor coaxially; an insulation layer surrounding the inner skin layer coaxially and made of polyethylene resin containing a plurality of foam cells uniformly formed therein; wherein the inner skin layer is made of polyolefin resin having excellent compatibility with the polyethylene resin to increase an interfacial adhesive force with the insulation layer, an outer skin layer surrounding the insulation layer coaxially to prevent overfoaming of the insulation layer and allow uniform creation of foam cells; a shield surrounding the outer skin layer coaxially; and a jacket surrounding the shield. This cable improves an interfacial adhesive force between the central conductor and the insulation layer and also improves the degree of foam of the foam cells, thereby capable of propagating ultra high frequency of GHz level without signal interference.

Foam coaxial cable and method for manufacturing the same

A micro coaxial cable includes an inner conductor; an insulation layer having foaming cells and formed to surround the inner conductor; an over-foaming preventing layer formed to surround the insulation layer for the purpose of uniform forming of the foaming cells; a metal shield layer formed to surround the over-foaming preventing layer; and a protective coating layer formed to surround the metal shield layer.
