Abstract: Disclosed are a power supplying apparatus, a backlight assembly and an LCD apparatus having the same. A control section outputs a switching signal so as to control an output of a constant current supplied to a lamp unit in response to on and/or off signals and a dimming signal and a switching section controls an output of a direct current voltage source in response to the switching signal. A power outputting section provides an alternating current voltage source having a constant voltage to the lamp unit. A sensing section senses variation of a power supplied to the lamp unit and a detecting section compares a sensing signal with a predetermined reference signal to output a detecting signal to the control section, thereby maintaining the constant current to be supplied to the lamp unit. Accordingly, the LCD apparatus may prevent deterioration of an image and damage of circuit thereof.

Abstract: Disclosed is a sunshade device for the rear door window of an automobile. Both ends of a sunshade screen rod, to which an end of the sunshade screen wound on the winding roll biased by an elastic member in a frame is fastened, are raised and lowered by a telescopic bar and an actuation arm, which are extended or retracted and erected or tilted through a single driving mechanism assembly including a driving motor, so as to spread or wind the sunshade screen.

Abstract: A membrane electrode assembly for a fuel cell provides a current collector adjacent to an electrode catalyst layer. Since electrons passing between the current collector and the electrode catalyst layer do not pass through a diffusion layer or a supporting layer, the diffusion layer or supporting layer may be non-conductive. Thus, various materials that are hydrophilic, hydrophobic, porous, hydrous, or the like can be used for the diffusion layer and the supporting layer, thereby improving the performance of the fuel cell. In addition, manufacturing costs of the membrane electrode assembly can be decreased since the membrane electrode assembly can be manufactured quickly with low energy.

The dielectric composition includes BaTiO3, MgCO3, Y2O3, Cr2O3, Mn2V2O7, and xBaO-yZrO2-zSiO2 acting as a sintering agent (where 0.1?x?0.3, 0.1?y?0.3 and 0.4?z?0.8, x+y+z=1), wherein when representing the composition with the formula aBaTiO3-bMgCO3-cY2O3-dCr2O3-e(Mn2V2O7)-f(xBaO-yZrO2-zSiO2), the ratio of the components satisfies the conditions of a=100, 0.1?b?3.0, 0.3?c?2.0, 0.05?d?0.2, 0.01?e?1.5, 0.5?f?3.0 based on the molar ratio. When manufacturing a multilayer ceramic capacitor of a higher capacitance, which is formed to have the thin layer structure of 4 ?m or less, short circuits between internal electrodes and the deterioration in capacitance due to massing of the electrodes into ball at the ends may be remarkably reduced.
