Abstract: Disclosed is a structure for discharging cold air in a refrigerator capable of uniformly distributing the cold air regardless of the upper part and the lower part of the refrigerator, by discharging the cold air in vertically downward direction. Therefore, temperature difference between the upper part and the lower part is reduced, so that temperature in the inside of the refrigerator could be uniformly maintained. Thanks to such structure having the foregoing advantages, additional equipment and space for supplying cold air to the shelf are not necessary any more like the case of the freezer or the cooling chamber according to the related art, having the structure where the discharging hole is formed on each shelf, so that the space of the refrigerator could be effectively used.

Abstract: An ink-jet cartridge includes a cartridge body forming an ink reservoir, a standpipe coupled to one side of the ink reservoir, a printhead formed under an ink supply passage formed by the standpipe, through which ink from the ink reservoir is ejected onto a printing medium in a droplet shape, and a filter which covers a top portion of the standpipe. The filter is formed in a convex shape protruding toward the printhead. Ink particles and bubbles flowing from the ink reservoir to the printhead are filtered out, bubbles which may flow from the printhead to the ink reservoir, move to edges of the filter, and the ink is smoothly supplied to the printhead.
