20150121698 | SCROLL ROTOR MOLD, MOLDING DEVICE, AND METHOD FOR MANUFACTURING MOLD - A mold for forging a scroll rotor capable of controlling material flow speed by adjusting a land section, a molding device applying same, and a method for manufacturing the mold. In the mold, a die includes an extrusion unit having a molding space therein and a spiral-shaped extrusion passage provided in the lower portion thereof so as to correspond to a wrap portion disposed in the scroll rotor. A punch is connected to the die to be in close contact with the inner circumference of the molding space and to be able to slide up and down. The lower portion has a shape corresponding to the upper surface of the flange portion of the scroll rotor and a boss portion. The extrusion passage has a land section in direct contact with the extrusion material. The length of the land section varies along the spiral direction. | 05-07-2015 |

20080291000 | COLLISION AVOIDANCE SYSTEM BASED ON DETECTION OF OBSTACLES IN BLIND SPOTS OF VEHICLE - The present invention relates to a collision avoidance system based on the detection of obstacles in the blind spots of a vehicle. The collision avoidance system includes turn signal lamp detection means for detecting whether a turn signal lamp of the vehicle is turned on. CCD camera means captures an image for a road environment, and outputs the captured image as road environment data, thus determining whether a current road environment indicates a winding road. Steering angle detection means detects a steering angle of the vehicle and outputs a resulting signal as a steering angle signal. Infrared sensor means transmits or receives infrared light to or from an obstacle present in the blind spot of the vehicle according to the steering angle signal, and outputs an obstacle detection signal. Warning means is configured to provide a warning of possibility of a collision between the obstacle and the vehicle to a driver. Control means automatically drives the warning means when the obstacle detection signal for the blind spot is received from the infrared sensor means in a case where a turn signal lamp is determined to be turned on by the turn signal lamp detection means, or where a lane change is determined to be performed by receiving the road environment data from the CCD camera means and the steering angle signal measured by the steering angle detection means. | 11-27-2008 |

20120241797 | LIGHT EMITTING DIODE, MANUFACTURING METHOD THEREOF, LIGHT EMITTING DIODE MODULE, AND MANUFACTURING METHOD THEREOF - A manufacturing method of a light emitting diode (LED) and a manufacturing method of an LED module are provided. The manufacturing method of the LED may include manufacturing a plurality of LED chips, manufacturing a phosphor pre-form including a plurality of mounting areas for mounting the plurality of LED chips, applying an adhesive inside the phosphor pre-form, mounting each of the plurality of LED chips in each of the plurality of mounting areas, and cutting the phosphor pre-form to which the plurality of LED chips are mounted, into units including individual LED chips. | 09-27-2012 |
20120305971 | LIGHT EMITTING DEVICE LENS, LIGHT EMITTING DEVICE MODULE INCLUDING LIGHT EMITTING DEVICE LENS AND METHOD FOR MANUFACTURING LIGHT EMITTING DEVICE MODULE USING LIGHT EMITTING DEVICE LENS - A lens according to an embodiment of the present invention may include a first depression and a second depression having predetermined patterns in a lower portion of the lens, and a phosphor layer and the lens may be collectively formed by disposing the lens after spraying a phosphor rather than separately forming the phosphor on the LED chip during a manufacture of the LED module. Accordingly, a production tolerance, and the like of an LED module may be removed to improve yield, and a manufacturing process of the LED module may be simplified. A lens may have an upper portion formed in advance in one of a hemispherical shape, an oval shape, and a batwing shape having a concave central portion, thereby implementing a customized lens according to a predetermined application. | 12-06-2012 |
