| 20090203872 | MANUFACTURING PROCESS FOR POLY (ARYLENE SULPHIDE) - This invention relates to a method of preparing poly(arylene sulfide) (PAS) from an iodo compound and a sulfur compound, and more particularly, to a method of preparing PAS, including adding a sulfur-containing polymerization terminator when PAS is produced using an iodo compound as an intermediate. Thereby, in final PAS, the residual iodine content may be maintained at the same level or decreased and other properties may be maintained at equal or superior levels, thanks to the use of the sulfur-containing polymerization terminator, which is much lower in price than conventional polymerization terminators. | 08-13-2009 |

| 20100234076 | MECHANICAL INPUT-OUTPUT DEVICE FOR MOBILE TERMINAL - A mechanical information input/output device of a mobile terminal permits various functions to be selected or adjusted according to changing positions of certain mechanical structures therein. The mechanical terminal preferably includes: a case for forming an external form with a predetermined form; and a mechanical information output unit provided at one side of the case and formed with at least one mechanical structure that changes a disposition by information according to a user function of the mobile terminal. | 09-16-2010 |
| 20110105081 | MULTI-SIM TERMINAL HAVING A PLURALITY OF TRANSMISSION KEYS AND METHOD OF OPERATING THE SAME - A multi-SIM terminal having a plurality of transmission keys and a method of operating the same in which the multi-SIM terminal has at least two subscriber identification modules (SIMS) and permits a selection of any particular SIM in the same action in which a communication is requested. The terminal multi-SIM includes at least two mounting units for mounting the at least two SIMS; and at least one transmission key having at least two states corresponding one-to-one to the at least two SIMS for transmission using one of the at least two SIMS. | 05-05-2011 |

| 20100040681 | Oral Sustained-Release Triple Layer Tablet - The present invention relates to an oral sustained-release triple layer tablet, more particularly, a triple layer tablet consisting of an inner immediate-release layer containing a pharmaceutically active ingredient and two outer layers containing swellable polymers. Upon exposure to aqueous media, the two outer layers swell to form gelled layers surrounding the lateral side of the inner layer rapidly, thereby control effectively the release of the pharmaceutically active ingredient from the inner immediate-release layer. | 02-18-2010 |
