| 20110085926 | MOTOR FOR COMPRESSOR AND HERMETIC COMPRESSOR HAVING THE SAME - Disclosed are a motor for a compressor and a hermetic compressor having the same. An aluminum coil cheaper than a copper coil is used in the motor for the compressor, to thusly reduce a fabricating cost. Also, a ratio of a height of end coil of a coil to an inner diameter of a stator is appropriately designed or a ratio of an entire area of slot portions to the inner diameter of the stator is appropriately designed, and simultaneously a ratio of the inner diameter of the stator to a width of the tooth portion is appropriately designed, so as to previously prevent a deterioration of damping effect, increase in noise, lowering of efficiency, reduction of driven torque, all caused due to the use of the aluminum coil. | 04-14-2011 |

| 20100099876 | METHOD OF PREPARING MONTELUKAST AND INTERMEDIATES USED THEREIN - The present invention relates to a method for preparing montelukast, an inhibitor against leukotrienes, and an intermediate used therein. According to the inventive method, high-purity montelukast or its sodium salt can be prepared in a high yield. | 04-22-2010 |
| 20110105757 | METHOD FOR PREPARATION OF MONTELUKAST ACID IN IONIC LIQUID MEDIUM - The present invention relates to a method for preparing Montelukast acid or its sodium salt by reacting a thiol compound with a Montelukast intermediate in the presence of a base in a medium comprising an ionic liquid compound. In accordance with the inventive method, highly pure Montelukast acid or its sodium salt, which is advantageously used as a raw material in the preparation of Montelukast, a leukotriene antagonist, can be easily prepared in a high yield. | 05-05-2011 |

| 20080273254 | IMAGING LENS ASSEMBLY, LIGHT SCANNING UNIT AND IMAGE FORMING APPARATUS HAVING THE SAME - An imaging lens assembly includes a mount which comprises a mount adhering portion on which a light curable adhesive is applied, an imaging lens which comprises a lens portion, and a supporting portion to extend from the lens portion, and a holder coupled to the mount adhering portion by the light curable adhesive, and to support the supporting portion. | 11-06-2008 |
| 20090153368 | TACTILE INPUT/OUTPUT DEVICE AND DRIVING METHOD THEREOF - A tactile input/output device and a driving method thereof are provided. The device includes at least one input end, at least one output end, and a controller. The input end includes a plurality of input cells arranged at regular intervals. The output end includes a plurality of output cells arranged at regular intervals. The controller senses an input signal of the input end and controls the output end to generate a corresponding output signal. The input end and the output end are installed to form one array with being separated. The input cell and the output cell are arranged so that they do not overlap with each other. | 06-18-2009 |
