20080212686 | METHOD OF REDUCING A BLOCKING ARTIFACT WHEN CODING MOVING PICTURE - A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S | 09-04-2008 |
20080225524 | Intense Pulse Light Device Having Individual Rotational Light filters Therein - Disclosed is an intense pulse light device, in which plural divided light filters coated with individually different materials are rotatably and uniformly aligned around a reflection mirror in order to selectively filter lights according to wavelengths thereof, so that it is not necessary to exchange a handle body or filters, thereby improving convenience of use for the IPL device, and in which the loose contact of power lines and signal lines, leakage of cooling water, and penetration of impurities can be prevented, thereby improving reliability of IPL device. A semicircular reflection mirror aligned around a flash lamp installed in a body and a light filter section is aligned around the reflection mirror while forming a predetermined space therebetween. The light filter section is uniformly divided into two or four light filters so as to increase selectivity for the light radiated from flash lamp. The light filter section is fabricated by uniformly dividing a circular pipe made from glass, quartz or sapphire into plural pipe sections, coating the plural pipe sections with individually different materials in such a manner that only light having a predetermined wavelength passes therethrough, and bonding the plural pipe sections to each other. | 09-18-2008 |
20090044891 | Compressed air pumping tire and compressed air storing apparatus using the same - Disclosed therein are a compressed air pumping tire for pumping compressed air from the tire while the vehicle travels and a compressed air storing apparatus using the compressed air pumping tire. The compressed air pumping tire includes: at least one air compression chamber formed in a body of the tire and having a volume to be filled with a predetermined amount of air, the air compression chamber compressing air in such a way as to be contracted by a contact force between the road surface and the tire surface while the tire runs; at least one air intake hole adapted to fluidically communicate with an end of the air compression chamber for sucking the outside air into a contracted space of the air compression chamber to thereby make the contracted space of the air compression chamber restored; and at least one air discharge hole adapted to fluidically communicate with the other end of the air compression chamber for discharging the compressed air to the outside. | 02-19-2009 |
20100086058 | METHOD OF REDUCING A BLOCKING ARTIFACT WHEN CODING MOVING PICTURE - A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S | 04-08-2010 |
20110231131 | FORGED SEAL IMPRINT INSPECTION METHOD AND RECORDING MEDIUM - Disclosed herein is a forged seal imprint checking method which includes a step ST- | 09-22-2011 |
20120018054 | STAINLESS STEEL MATERIAL HAVING OUTSTANDING HIGH-TEMPERATURE STRENGTH, AND A PRODUCTION METHOD THEREFOR - Provided are a stainless steel having excellent high-temperature strength and a method of manufacturing the same, and more particularly, an austenitic stainless steel having excellent high-temperature and creep strength as well as excellent corrosion resistance able to be used in high-temperature corrosive environments such as power plants and a method of manufacturing the same. The stainless steel of the present invention may have a precipitation index of 1.5 to 2.5. | 01-26-2012 |
20120134874 | ALUMINUM CASTING MATERIAL COMPRISING TITANIUM BORIDE AND METHOD OF MANUFACTURING THE SAME - Disclosed is an aluminum casting material including aluminum, silicon, titanium and boron, particularly 81-93 wt % of aluminum, 5-13 wt % of silicon, 1-3 wt % of titanium and 1-3 wt % of boron. The aluminum casting material has superior elasticity compared to that of a conventional aluminum alloy, even without employing a material of high cost such as carbon nanotube (CNT). While the application of the conventional aluminum alloy is largely restricted to a low pressure casting process, the aluminum material of the present invention can be applied to all common casting processes including a high pressure casting. | 05-31-2012 |
20130040220 | OXIDATION-RESISTANT FERRITIC STAINLESS STEEL, METHOD OF MANUFACTURING THE SAME, AND FUEL CELL INTERCONNECTOR USING THE FERRITIC STAINLESS STEEL - An oxidation-resistant ferritic stainless steel comprising: a ferritic stainless steel comprising Cr, wherein a {110} grain orientation fraction of a surface of the ferritic stainless steel as measured using electron back scattered diffraction pattern (EBSD) is about 5% or more; and a chromium oxide layer formed on the surface of the ferritic stainless steel is provided. | 02-14-2013 |
20130143141 | OXIDATION RESISTANT FERRITIC STAINLESS STEEL, METHOD OF MANUFACTURING THE STEEL, AND FUEL CELL INTERCONNECT USING THE STEEL - An oxidation-resistant ferritic stainless steel including a ferritic stainless steel base material, and a Cu-containing spinel-structured oxide. | 06-06-2013 |
20140140920 | VANADIUM-BASED HYDROGEN PERMEATION ALLOY FOR MEMBRANE, METHOD OF MANUFACTURING THE SAME, AND METHOD OF USING THE MEMBRANE - A vanadium-based hydrogen permeation alloy for a membrane, a method of manufacturing the same, and a method of using a membrane including the same are provided. The vanadium-based hydrogen permeation alloy for a membrane includes nickel (Ni) at more than 0 atm % and 5 atm % or less, iron (Fe) at 5 atm % to 15 atm %, yttrium (Y) at more than 0 atm % and 1 atm % or less, and a remainder of vanadium and impurities. | 05-22-2014 |
