Abstract: The present invention relates to a metal frame for a mobile communication terminal, manufactured using extruding and a die casting die. The metal frame for the mobile communication terminal, manufactured using extrusion and the die casting die includes a housing frame formed by cutting a metal preform having a square pipe shape obtained by extruding a metal material such as an aluminum alloy to have a square ring shape having a hollow square cross section to form an edge exterior of the mobile communication terminal and a bracket frame formed by inserting the housing frame into the die casting die and injecting a molten metal thereinto to be a flat panel member which supports a display panel and a main board of the mobile communication terminal inside the housing frame.

Abstract: Provided is an apparatus for hardening ultraviolet (UV) gel for nails, the apparatus including: a housing which is configured in such a way that an upper case of the housing ascends/descends and is rotatable with respect to a lower case so that enlargement/reduction and adjustment of a facing angle between the upper case and the lower case are capable of being performed; a mounting portion disposed on a top surface of the lower case so as to correspond to lengths and distances of user's fingers so that the user's fingers are capable of being mounted on the mounting portion; and UV mounting portions disposed on a bottom surface of the upper case to have an arrangement corresponding to the mounting portion so that UV rays are capable of being concentratively radiated onto user's nails placed on the mounting portion.
