20120325103 | COUPLING DEVICE FOR EXPLOSIVES - A coupling device which is configured such that respective explosives for blasting work are coupled to front and rear sections thereof. The coupling device includes cylindrical bodies, one of the bodies being movable away from or close to another one of the bodies, a partition provided inside a predetermined one of the bodies to divide an inner space of the predetermined body, and an expandable support section provided between the bodies to connect the bodies to each other. The expandable support section forms a cylindrical shape together with the bodies when one body is moved away from the other body and is radially expanded when one body is moved close to the other body. The explosives can be easily inserted into a blasting hole and be positioned in the center of the blasting hole, thereby increasing the efficiency of blasting work. | 12-27-2012 |

20110019519 | OPTICAL DISC RECORDING METHOD AND OPTICAL DISC APPARATUS - This document relates to a method of compensating for a sensitivity variation of a tracking actuator with focusing offset when recording labels on a disc for label recording. A focusing point suitable for the position of an object lens in the circumference direction and/or the radius direction is detected, a tracking sensitivity corresponding to the detected focusing point is obtained based on information about a tracking sensitivity variation according to a focusing point variation, and labels are recorded on a label plane using the detected focusing point and tracking sensitivity. The information may be measured using at least two different types of discs one of which has a distance, between the surface of the disc and a pattern area required for a feed forward servo operation, different from the distance of the other. | 01-27-2011 |

20150117045 | HEAD LAMP FOR VEHICLE - A head lamp for a vehicle includes a light source configured to emit a light and a reflective mirror configured to reflect the light. A reflective mirror extended portion extends toward a front of the head lamp from the reflective mirror. An upper shield protrudes radially toward an inner side of the head lamp and shields the light. A lower shield extends toward the front of the head lamp, such that a part of the light transmitted from the light source is indirectly transmitted to the front of the head lamp. A light developing hole is formed between the upper and lower shields to allow another part of the transmitted and reflected light to pass therethrough. A lens mounted to one end of the reflective mirror extended portion allows the light passing through the light developing hole to penetrate the lens and emit the penetrated light toward a front view of the vehicle. | 04-30-2015 |
