| 20100132562 | Electric precipitator and electrode thereof - An electric precipitator prevents dielectric breakdown by ensuring the dielectric distance among a plurality of electrodes. The electric precipitator includes a charging section for charging dust particles in air, and a collecting section for collecting the dust particles charged by the charging section. The collecting section includes a high voltage electrode having a conductive layer coated with a dielectric layer, and a low voltage electrode having at least one protrusion that maintains a gap between the high voltage electrode and the low voltage electrode. The conductive layer includes at least one cutting part formed in an area corresponding to the protrusion. | 06-03-2010 |
| 20110056222 | Refrigerator - A refrigerator having a water supply device integrally formed with a rear surface of a storage chamber thereof. The refrigerator includes a storage chamber door to open and close a storage chamber, a dispenser mounted to the storage chamber door, and a water supply device separably connected to a rear surface of the storage chamber door adjacent to the dispenser, so as to supply water to the dispenser. | 03-10-2011 |

| 20090142268 | CHAIN-END FUNCTIONALIZED POLY(ETHYKENE OXIDE) AND PROCESS FOR THE PREPARATION OF A NANO-SIZED TRANSITION METAL OR METAL SALT USING THE SAME - There is provided a novel chain-end functionalized PEO of formulas (I) to (IV) prepared via living anionic polymerization and chain-end functionalization, as well as a simple method of preparing nano-sized transition metal or metal salt particles using the same, which can be readily stabilized even in an aqueous medium. The water-soluble PEO-based polymers having various functional groups (including a drug group such as vitamin and anti-cancer agent) and the process of preparing nano-sized transition metal or metal salt particles using the same can be advantageously used in the development of new materials for drug delivering system and imaging, e.g., a contrast agent and an anti-cancer agent simultaneously. | 06-04-2009 |

| 20110051719 | PROVIDING A CALL SERVICE IN A COMMUNICATION NETWORK - Methods and systems for providing company call service in wireless and wired integrated network are provided. For example, a call between an employee's wireless device and a client's device can be connected while indicating the employee's wired telephone number as a caller's telephone number. When an employee is receiving a call, one example is to call an employee's wired device first, and if there is no response, employee's wireless device may be called subsequently. In another example, employee's wired and wireless device may be called simultaneously. | 03-03-2011 |

| 20110182530 | DUAL COMPARTMENT POUCH HAVING PRESSURE-OPENABLE NON-SEALING LINE AND HEAT SEALING MOULD THEREFOR - The present invention provides a duplex pouch and a heat-sealing mould for manufacturing the same. The duplex pouch has a pressure-openable non-sealing line of which a specific portion can be opened by a dynamic load that is generated when an external force is applied thereto, and includes a first chamber and a second chamber that are sealed by an external sealing line at their edges and a middle portion of the two chambers is heat-sealed by an inside sealing line to contain different types of liquid contents, respectively, a pressure-openable portion formed at the middle portion of the inside sealing line, a non-sealing unit formed in a rounded triangular or semicircular shape at the center of the pressure-openable portion by first and second branch sealing lines divided by the inside sealing line and then extended, a long non-sealing line provided in a middle of the first branch sealing line and communicating the first chamber and the non-sealing unit, and a short non-sealing line provided in the middle of the second branch sealing line and communicating the non-sealing unit and the second chamber. The heat-sealing mould forms the pouch by heat-sealing two sheets of films, and long and short notches may be formed in the first and second branch sealing pads that correspond to the first and second branch sealing lines, or long and short heat sinks may be formed between the first and second branch sealing lines. | 07-28-2011 |
