| 20100038255 | SN-B PLATING SOLUTION AND PLATING METHOD USING IT - The object of the present invention is to prevent generation of whisker in a Pb-free plating layer. Provided is a Pb-free Sn—B plating solution containing tin sulfate, which is a source of Sn ions, and dimethyl amine borane or trimethyl amine borane, which is a source of B ions. | 02-18-2010 |
| 20100055496 | STEEL HAVING HIGH STRENGTH - A steel having an improved tensile strength includes a first layer formed of an ultra-low carbon steel; and a second layer that is formed in contact with the first layer, includes a first surface opposite to the first layer, is formed of a solid solution obtained by solid-solving nitrogen in the ultra-low carbon steel, and has a structure substantially the same as a structure of the first layer. | 03-04-2010 |
| 20100092335 | PB-FREE SOLDER ALLOY - The present invention is provided to prevent the generation of whiskers via a lead (Pb)-free solder alloy. To achieve this objective, the present invention provides a Pb-free solder alloy including tin (Sn) as a first element and either boron (B) or beryllium (Be) as a second element. | 04-15-2010 |
| 20110038135 | METAL FRAME FOR ELECTRONIC PART - Provided is a metal frame for an electronic part and capable of minimizing defects such as an electric short circuit caused by whiskers. The metal frame may include a lead unit electrically connected to an electronic device, and the lead unit may include a first metal layer that contains copper (Cu) as a main component and further contains boron (B) or beryllium (Be). | 02-17-2011 |

| 20100296265 | ILLUMINATION LENS AND ILLUMINATION UNIT INCLUDING THE SAME - An illumination lens including a first part being free of prismatic patterns, a second part including prismatic patterns on both sides of the first part and configured to increase light distribution in the both sides of the first part, and a lens cover covering the first and second parts with the first and second parts being disposed on a substantially same plane under the lens cover. | 11-25-2010 |
| 20100309660 | Lighting device - A lighting device includes a case body including a receiving cavity and at least a portion including at least one first hole, a light emitting module in the receiving cavity, the light emitting module including a plurality of light emitting devices, a lens on the light emitting module, and a case cover including an opening through which the lens is exposed, the case cover being disposed on the case body. A heat sink is between the light emitting module and the case body to transfer heat from the light emitting module to the case where the case body acts as a conduit to transfer heat from the light emitting module to the portion of the case body including at least one first hole and the case cover has at least a portion including at least one second hole and the first hole of the case body corresponds with the second hole of the case cover. | 12-09-2010 |

| 20110188244 | GAP MEMBER, LENS AND LIGHTING DEVICE HAVING THE SAME - A lighting device and a gap member and a lens used in a lighting device. The lens may include a circular incident surface that has a furrow surface crossing a surface and prism surfaces formed at both sides of the furrow surface; and an exit surface that reflects and transmits light traveling inside through the incident surface to the outside. The gap member may include a ring-shaped reflective portion having a declined surface toward the center; and a ring-shaped wall extending downward coaxially with the reflective portion, and has a flat ring shape. The lighting device may include a substrate; a light emitting unit including a plurality of LEDs mounted on the substrate; a case body accommodating the light emitting unit; a lens disposed on the light emitting unit; a first waterproof ring disposed around the lens; and a case cover having an opening that exposes the lens, and combined with the case body and the first waterproof ring. | 08-04-2011 |
