The package substrate includes a substrate having at least one conductive pad; an insulating layer provided on the substrate and having an opening to expose the conductive pad; a separation barrier layer provided on the conductive pad inside the opening and formed to be higher than the upper surface of the insulating layer along the side walls thereof; a post terminal provided on the separation barrier layer; and a solder bump provided on the post terminal.
Abstract:
A vacuum roll-to-roll device includes: a first chamber; a second chamber neighboring the first chamber; a shutter disposed between the first chamber and the second chamber; a sealing member attached to the shutter; and a roll-type substrate which moves from the first chamber to the second chamber through the sealing member. A thickness of a lateral side of the roll-type substrate decreases in a direction toward an edge thereof.
Abstract:
A heat exchanger having an extended surface plate includes a plurality of heat exchanging bodies having therein flow paths along which a heat transfer medium flows, and extended surface plates each disposed between the heat exchanging bodies and having inclined surfaces in horizontal and vertical directions. Also disclosed is a dehumidifier having the heat exchanger. Moisture in the air may be effectively absorbed by a dehumidifying liquid, and the heat exchanger may have enhanced structural strength.
Abstract:
A printing apparatus includes a master board and a feeding part. The master board includes first and second planes different from each other, a patterned reservoir formed on the first plane, and an injection hole connected to the patterned reservoir by extending from the second plane through an inside of the master board. The feeding part feeds the ink into the patterned reservoir through the injection hole. The ink is supplied to the patterned reservoir through the injection hole. The feeding part feeds a predetermined amount of ink into the patterned reservoir through the injection hole so that the ink is prevented from overflowing out of the patterned reservoir. Thus, an additional process to remove ink overflowing out of the patterned reservoir is not necessary.
Abstract:
A touch display panel may include a display unit and a touch unit. The display unit may include a first base substrate having a plurality of pixel electrodes, a second base substrate including a common electrode disposed on a first face of the second base substrate, and an electro optical layer disposed between the pixel electrodes and the common electrode. The first face faces the first base substrate. The touch unit includes a color filter layer including a plurality of color filters and a first electrode part including first electrodes disposed on a second face of the second base substrate, and a third base substrate including a second electrode part extended along a direction crossing the first electrodes. The first electrodes may be disposed on a boundary area of the color filters having different colors from each other, so that mixing of the colors is prevented.
Abstract:
An air conditioning system using for a dehumidifying cooling device has developed that comprising a heating source for producing hot water, a heat exchanger for transferring heat from the hot water to circulating water, a circulation pump for circulating the resulting hot water heated in the heat exchanger, a heating pipeline connected to the circulation pump for conveying the hot water to a heat supply target area, a user heat exchanger connected to the heating pipeline for conveying hot water to the heat supply target area, a dehumidifying cooling device connected to a hot water pipe of users heat exchanger and installed in each household within the heat supply target area, the dehumidifying cooling device removing moisture from the air by using hot water supplied from the hot water pipe to deal with latent heat load and to lower the temperature of the dehumidified air via evaporation of water contained in the air.
Abstract:
Disclosed are a dehumidification apparatus, and an air conditioning apparatus and system having the same. The dehumidification apparatus includes: a desiccant rotor having a desiccant for adsorbing moisture; and a regeneration unit disposed at one side of the desiccant rotor, for desorbing the moisture adsorbed to the desiccant. The regeneration unit includes at least one of a hollow hot water line containing hot water exchanging heat with the air flowing toward the desiccant rotor. The dehumidification apparatus efficiently reproduces the desiccant for dehumidification and air conditioning.
Abstract:
Disclosed is a louver fin type heat exchanger positioned upright at a certain angle with respect to the ground, wherein lower end portions of louver fins close to the ground are bent toward lower end portions of adjacent louver fins, such that the air passage at the lower end portion close to the ground has cross-section areas that are wide at certain portions and are narrow at other portions thereof. Accordingly, moisture congregates only at a portion where the cross-section of the air passage is great, so that the external air smoothly passes into or out the heat exchanger through the air passage where the moisture congregation does not occur, minimizing the pressure drop, and efficiency in heat exchange of the heat exchanger can be thusly improved.
Abstract:
An evaporative humidifier for a polymer electrolyte membrane fuel cell system including a fuel cell stack, comprising: a condensation channel to which exhaust gas from the fuel cell stack is introduced; an evaporation channel to which supply gas for the fuel cell stack is introduced; a partition wall for separating the condensation channel and the evaporation channel from each other; and a water distribution unit for supplying water into the evaporation channel, wherein the water is condensed in the condensation channel by heat exchange between the exhaust gas and the supply gas.
