Abstract: A switch apparatus, includes: a base module including a base case, and a moving magnet movably mounted in the base case; and a manipulation module including a manipulation case, and a first magnet fixedly mounted in the manipulation case, wherein the moving magnet moves between a hold position and a releasable position, the hold position refers to a position in which the manipulation module is held onto the base module as an attractive force acts between the moving magnet and the first magnet, and the releasable position refers to a position in which the manipulation module is releasable from the base module as a repulsive force acts between the moving magnet and the first magnet.

Abstract: The present invention relates to a multi-component host material and an organic electroluminescent device comprising the same. By comprising a specific combination of the multi-component host compounds, the organic electroluminescent device according to the present invention can provide high luminous efficiency and excellent lifespan characteristics.

Abstract: Provided is a wind-collecting type wind power generating apparatus installed on a roadside, which performs power generation using traveling wind of vehicles traveling on the road. The wind power generating apparatus includes a power generation main body accommodating a power generator and buried under the ground, a support extending upwardly from the power generation main body, a blade located at the upper end of the support and rotated by wind to drive the power generator, a wind collecting guide surrounding a part of the circumference of the side surface of the blade, rotatably connected to the blade, collecting wind and guiding the wind to the blade, and a cover steering unit protruding from one side of the upper end of the wind collecting guide to rotate the wind collecting guide according to the direction of wind so that a wind inlet is opposite a wind blowing direction.

Abstract: The present invention relates to a longitudinally divided emergency core cooling (ECC) duct in order to efficiently inject safety water to core of a pressurized light-water nuclear reactor. The ECC duct includes side supports for preventing the flow-induced vibration in the annular downcomer, and has structural stability while thermally expanding and contracting. A longitudinally divided ECC duct for emergency core cooling water injection of a nuclear reactor is provided on the periphery of a core barrel of a nuclear reactor, includes an emergency core cooling water inlet facing a direct vessel injection nozzle, and extends in a longitudinal direction of the core barrel. The longitudinally divided ECC duct is divided into a plurality of longitudinally-divided ducts in the longitudinal direction of the longitudinally divided ECC duct.
