The first and second spray guns spray paints to different portions of the object to be painted. | 02-11-2010 |
20100119842 | INJECTION PREFORM PLASTIC HAVING SURFACE EFFECT OF METALLIC APPEARANCE - An injection preform providing a metallic texture and a fabrication method thereof, in which on a surface of an injection substrate whereon a thin-film primer coating layer (TPPCL) is formed providing the metallic texture formed with various patterns and to preserve the texture on the surface of the injection substrate. The injection preform typically includes: an injection substrate having a surface on which the various patterns are formed by mold discharge corrosion; a TPPCL formed on the surface of the injection substrate to increase reflectivity of the injection substrate, so that the TPPCL provides the metallic texture with various patterns while preserving surface texture of the injection substrate; a non-conductive metal-deposited layer deposited on a surface of the thin film primer coating layer; a color coating layer (CCL) formed on a surface of the non-conductive metal-deposited layer; and a clear layer formed on a surface of the CCL. | 05-13-2010 |
20100129661 | COATING COMPOUND FOR PORTABLE ELECTRONIC APPARATUS AND COATING METHOD FOR THE PORTABLE ELECTRONIC APPARATUS - A coating compound and method for a portable electronic apparatus having frequent contact with users, such as a portable terminal, a Portable Multimedia Player (PMP), a Personal Digital Assistant (PDA), or the like. A housing of the portable electronic apparatus has the coating compound coated arranged thereon, and a bead portion is blended and added to the coating compound prior to applying the coating compound onto the housing so that convexes and concaves are formed on and in an outer surface of the housing by the bead portion. The coating method includes manufacturing a housing of the portable electronic apparatus by injection, coating the coating compound onto the manufactured housing, and drying the coating compound coated onto the housing so that particles of acrylic beads and urethane beads included in the coating compound protrude from an outer surface of the housing. | 05-27-2010 |
20100245253 | KEYPAD FOR ELECTRONIC DEVICE AND MANUFACTURING METHOD THEREOF - A keypad for an electronic device and manufacturing method thereof having at least one or more ink layers which selectively let pass or cut off a light wavelength of at least one or more light emitting diodes generating light in accordance with an opened or closed direction of a folder. At least one or more light emitting elements for generating light in various colors are provided, and a diffusion ink layer is arranged above the light emitting elements. At least one or more ink layers provided on the diffusion ink layer, wherein the ink layers selectively let passes or cut-off light wavelengths of the light emitting elements when the folder is rotated or slid in a longitudinal or perpendicular direction. A transparent or semi-transparent ink layer is provided on the ink layers, and a sheet film layer is provided on the transparent or semi-transparent ink layer. | 09-30-2010 |
