Abstract:
A refrigerator including a receptacle provided in a storage chamber of a main body so that the receptacle is moved forward from and backward into the storage chamber, a cover hingedly provided at the receptacle, and an interlocking unit to interlock forward and backward motions of the receptacle and hinged rotation of the cover when the receptacle is moved forward by a predetermined distance.
Abstract:
In a clamping jig and system for inspecting spacer grids for a nuclear fuel assembly, the jig firmly and precisely clamps a variety of grids on a measurement stage moving at high speed so that, among constituent parts of the nuclear fuel assembly, the spacer grids can be inspected using a non-contact measurer. The clamping jig includes a frame having a plurality of holding recesses into which the corresponding spacer grids are inserted, supporting means mounted in each holding recess of the frame to allow each spacer grid to be adjusted from below so it can be maintained in a horizontal state, clamping means installed around each holding recess to clamp two adjacent sides of each spacer grid to a corner of the respective holding recess, and resilient means installed on the sides opposite the clamping means and resiliently supporting the other two sides of each spacer grid.
Abstract:
An antenna ground structure of a mobile terminal is disclosed. The antenna ground structure of a mobile terminal is arranged to provide the ground pattern on a Printed Circuit Board (PCB) adjacent to the antenna and to electrically connect the ground pattern to the ground unit of the antenna, so that the area of the ground of the antenna may be expanded to improve Specific Absorption Rate (SAR) and communication performance.
Abstract:
The present invention relates to novel Forms A, B, C, D, E, F and G of crystalline 9-[2-[phosphonomethoxy]ethyl]adenine bis-pivaloyloxymethyl ester, i.e., adefovir dipivoxil, and processes for preparing them. According to the present invention, said novel crystal forms having a high purity can be obtained by a simple method and in a high yield.
Abstract:
Disclosed are a plug interlock device for a circuit breaker and a circuit breaker having the same, wherein a plug is not allowed to be separated from a connector while a breaker main body is moved from a test position to a run position or is running at the run position, thereby obviating the plug from being unexpectedly unplugged from the connector while the breaker main body is moved from the test position to the run position or is running, resulting in preventing a safety accident in advance.
Abstract:
A portable personal self-operating life tube is disclosed, in which when a user is drowned in water due to a marine disaster or a fire and sinking of a ship, it automatically operates, so the user can save his life by just wearing the tube, and the tube is able to keep a user's a body temperature until a rescue comes after the tube is expanded along with the above features, and a life tube can be easily used without a particular care by improving the problems found in a conventional art in which a user feels bad when wearing a life tube since a conventional life equipment is not customized, and it is not portable and is not easy to use.
Abstract:
A surface light source device using light emitting diodes, the device including: a housing having a top opening to emit light; a light emitting diode board disposed on an inner bottom surface of the housing, the board on which a plurality of light emitting diodes are arranged; and a color conversion laminate formed by depositing a plurality of phosphor-mixed resin layers containing phosphors, the layers disposed at a top of the opening of the housing and providing light having different wavelengths.
Abstract:
A robot cleaner that cleans a cleaning region while traveling the cleaning region and a method to control the same are provided. The robot cleaner can uniformly clean a cleaning region based on a wall-following technique which allows the robot cleaner to travel along the outline of the cleaning region. The method selects, as a reference wall, a wall at a left or right side of the robot cleaner at a start position of the robot cleaner based on a left or right-based travel algorithm, which allows the robot cleaner to travel along a left or right wall, and controls the robot cleaner to travel the cleaning region in a zigzag travel pattern in which the robot cleaner moves a predetermined distance in a direction perpendicular to the reference wall at specific intervals along the selected reference wall while following the selected reference wall.
Abstract:
There is provided a turntable and an optical disc driver. The turntable includes an assembly groove into which a clamp plate is inserted and at least one fixing jaws formed in the assembly groove to be fastened to the clamp plate. The optical disc driver includes a clamp plate including at least one fastening holes formed on the circumference thereof and fixing protrusions formed in the fastening holes and a turntable including an assembly groove into which the clamp plate is inserted and at least one fixing jaws formed in the assembly groove to be fastened to the fixing protrusions of the clamp plate.
