Patent number: 9505961Abstract: The present invention relates to an acrylic pressure sensitive adhesive composition comprising a monomer containing linear carbonate having an antistatic property. The acrylic pressure sensitive adhesive composition exhibits an excellent balance between low-rate peel strength and high-rate peel strength, and is capable of lowering the content of an antistatic agent. It also provides excellent releasable property, and protection of the surface of a polarizer due to proper wettability.Type: GrantFiled: December 9, 2008Date of Patent: November 29, 2016Assignee: LG Chem, Ltd.Inventors: No-Ma Kim, Jae-Gwan Lee, An-Na Lee, Suk-Ky Chang

Patent number: 8570439Abstract: A broadcasting processing apparatus and a control method thereof are provided. The apparatus includes a signal receiver which receives an image signal having image content; a user selection unit which selects movie content from the image content; a storage unit; and a controller which determines whether a received image signal is a film image signal if the movie content is selected through the user selection unit, and stores the image signal in the storage unit if the image signal corresponds to the film image signal.Type: GrantFiled: February 7, 2008Date of Patent: October 29, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: An-na Lee

Patent number: 8329847Abstract: The present invention relates to an acrylic pressure-sensitive adhesive composition which comprises a (meth)acrylic copolymer comprising 70 to 95 parts by weight of an alkyl(meth)acrylic acid ester monomer, in which alkyl has 2 to 14 carbon atoms, and 5 to 30 parts by weight of a (meth)acrylic acid ester monomer containing a copolymerizable aromatic group, wherein the composition has a gel fraction of 10 to 55% and a swelling ratio of 30 to 110, and a sol (uncross-linked polymer) eluted therein with a solvent has a weight average molecular weight of 600,000 or more; a polarizing plate comprising the composition; and a liquid crystal display device comprising the same. The composition according to the present invention provides workability such as an excellent durability and re-workability, and has an effect of improving a light leakage phenomenon, since the size of birefringence occurred under stress is very small.Type: GrantFiled: July 10, 2007Date of Patent: December 11, 2012Assignee: LG Chem, Ltd.Inventors: No-ma Kim, In-Cheon Han, Jeong-Min Ha, An-Na Lee, Seung-Joon Park, Suk-Ky Chang

Publication number: 20070103269Abstract: A thermistor, which is to be mounted on a PCB, for protecting other circuit elements is disclosed. Electrode patterns separately formed on both surfaces of a film resistance element are respectively shaped into two parts which are engaged to each other with a non-conductive gap interposed therebetween. Thus, a Tombstone phenomenon caused by asymmetric structure may be fundamentally prevented. Grooves are formed in both sides of the thermistor, and connection portions for electrically connecting the electrodes formed on both surfaces of the thermistor are formed through the inside of the grooves or through the sides except the grooves. Thus, though a crack arises in the connection portion, it is possible to prevent the crack from being propagated to the entire connection portion along the side of the thermistor.Type: ApplicationFiled: December 19, 2006Publication date: May 10, 2007Inventors: Jun-Ku Han, Su-An Choi, Chang-Mo Ko, An-Na Lee, Jong-Hwan Lee, Ju-Dam Kim, Jong-Ho Lee, Dong-Hyun Kim

Patent number: 7173512Abstract: A thermistor of which resistance is changed depending on temperature and a secondary battery to which the thermistor is attached are disclosed. The thermistor is attached to an object via a lead which is made of different kinds of materials. The lead is configured so that a part of the lead to be united to the thermistor electrode is mainly made of the same material as the electrode and a part of the lead to be united to the object is mainly made of the same material as the surface of the object. Thus, the thermistor may be simply attached to the object only using the ultrasonic welding, thereby remarkably reducing junction inferiorities.Type: GrantFiled: July 9, 2004Date of Patent: February 6, 2007Assignee: LG Cable, Ltd.Inventors: Chang-Mo Ko, Su-An Choi, Jun-Ku Han, An-Na Lee, Jong-Hwan Lee, Ju-Dam Kim, Jong-Ho Lee, Jong-Seo Yoon

Patent number: 7145431Abstract: A thermistor is disclosed, which comprises a resistance element having upper and lower surfaces and showing a resistance varying characteristics according to the change of temperature; first and second conductive layers formed on the upper surface of the resistance element and engaged to each other with a non-conductive gap interposed therebetween; first and second electrodes formed on the lower surface of the resistance element and electrically separated from each other; a first connector for electrically connecting the first conductive layer to the first electrode; and a second connector for electrically connecting the second conductive layer to the second electrode. Thus, the thermistor has a structurally point-symmetric shape, so it is possible to prevent the Tombstone phenomenon, caused by an asymmetric structure.Type: GrantFiled: November 28, 2003Date of Patent: December 5, 2006Assignee: LG Cable, Ltd.Inventors: Jun-Ku Han, Su-An Choi, Chang-Mo Ko, An-Na Lee, Jong-Hwan Lee, Ju-Dam Kim, Jong-Ho Lee
