摘要:
Disclosed is a method for manufacturing an electronic device using LDS and an electronic manufacturing by the method, in which resin for LDS is adhered to an inner surface of an external case by double injection or insert injection so as to implement a circuit. The electronic device using LDS includes upper and lower external cases, wherein resin for LDS is adhered to an inner surface of the lower external case by double injection or insert injection. Components of the electronic device are mounted on the resin, and the upper and lower external case are assembled with each other.

A temperature control system for a mold includes a circulation pipe provided in the mold, a heating water circulation section to provide heating water to the circulation pipe to pre-heat the mold, a cooling water circulation section to provide cooling water to the circulation pipe to cool the mold, and a compressed air circulation section to provide compressed air to the circulation pipe to eject remaining heating water or cooling water within the circulation pipe. The compressed air circulation section is adapted to supply the compressed air to the circulation pipe to eject remaining fluid within the circulation pipe before heating water or cooling water is provided to the circulation pipe.

An apparatus and method for supporting Peer to Peer (P2P) communication in a broadband wireless communication system are provided. A P2P zone within a frame used for the P2P communication includes at least one channel, each channel includes a broadcasting zone and a contention zone, and a P2P-mode transmit Mobile Station (MS) transmits a reference signal through a broadcasting zone of a channel to which itself belongs. The method MS includes determining an interference sum for each channel within the P2P zone, comparing the determined interference sums with each other, selecting a channel having the least interference sum, and transmitting information regarding the selected channel to a Base Station (BS).
摘要:
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.

Disclosed is a manufacturing method of a keypad for a mobile phone and the keypad manufactured thereby, in which a vacuum deposition layer and a cellophane paper are attached to a lower surface of a key in the keypad. The keypad for a mobile phone includes a plurality of keys, each key includes a key body of a transparent resin material and a high-hardness transparent coating layer coated onto a surface of the key body in order to increase hardness, and each key comprises a key background color paint layer for color presentation, coated onto a lower surface of the key body; an opaque paint layer coated onto a lower surface of the key background color paint layer; a transparent marking portion formed by performing a laser processing according to a shape of a numeral, a character, or a symbol with respect to the lower surface of the key body so as to remove the color paint layer and the opaque paint layer; a metallic vacuum deposition layer formed on the lower surface of the key body and a lower surface of the opaque paint layer; and a transparent color-printed layer or a cellophane paper attached to a lower surface of the metallic vacuum deposition layer so as to present various colors.
摘要:
Provided is an injection-molded product manufactured of a synthetic resin having light permeability, the injection-molded product including a pattern structure formed on an inner surface of the injection-molded product and a coupling structure formed on the pattern structure, in which the coupling structure is hidden by the pattern structure from an outer surface of the injection-molded product. The injection-molded product may be manufactured of a transparent material so that the coupling structure or reinforcing structure, can be hidden visually. Various colors can be used in the surface treatment, such as painting or deposition, on the injection-molded product.
摘要:
A sliding apparatus of a sliding type portable terminal allows a sliding housing of the sliding type portable terminal to slide in two directions. The sliding apparatus of a sliding type portable terminal includes a main housing including a fixing member and a sliding housing slidably coupled with the main housing. The sliding housing includes a guide part that is engages with the fixing member to guide the sliding housing along a curved path on the main housing in a left direction and a right direction about a central axis of the fixing member.
