Abstract:
Disclosed is a helical turbine power generation system for generating electricity by using a helical turbine and a synchronous generator, the system including: a helical turbine rotatably provided in a frame so as to continuously generate rotation force under unidirectional or multidirectional fluid flow; a step-up gear for increasing a rotational velocity of the helical turbine up to a level required for generating electricity; a fluid coupling for preventing the rotational velocity increased by the step-up gear from increasing above a required velocity at a temporarily high rate of fluid flow; and a synchronous generator for generating electricity by using the rotational velocity transferred from the fluid coupling. Therefore, it is possible to reduce equipment costs and to prevent environmental pollution.
Abstract:
A backlight assembly comprises a light source unit emitting light, a heat-blocking plate disposed over the light source unit to prevent heat generated from the light source unit from being upwardly transmitted, and a receiving container receiving the light source unit and the heat-blocking plate. The receiving container includes a bottom plate and a plurality of sidewalls. Each of the sidewalls extends from a side of the bottom plate and has openings formed through each of the sidewalls. The openings are formed over the heat-blocking plate.
Abstract:
A liquid crystal display device in which an integrated printed circuit board is manufactured by integrating a circuit of a gate portion with a source portion and is located on the source side of the liquid crystal panel, and a flexible circuit board according to the COF method is provided on the gate side, and the flexible circuit board is supported towards a mold frame to reduce the area and the volume which is occupied by a portion except for a screen is disclosed. The liquid crystal display device comprises a liquid crystal display panel, an integrated printed circuit board, a flexible circuit board for transferring a gate driving signal and a data driving signal to the liquid crystal display panel, and a mold frame for receiving the liquid crystal display panel and a back light assembly. A support member for supporting the flexible circuit board towards the mold frame is provided on one side of a chassis. Since the gate side flexible circuit board is easily supported by the support member towards the mold frame, the planar area increasing of the liquid crystal display device is prevented.
