Abstract: A substrate bonding apparatus for use in fabricating LCD devices substantially prevents substrates held to upper stages from sagging. The substrate bonding apparatus may, for example, include upper and lower stages having a plurality of passages for holding respective substrates; suction force applying means having one end mounted within each passage for transmitting a suction force to operably proximate portions of a substrate, wherein the one end of the suction force applying means is projectable from within each passage to a predetermined distance from the stage; and a vacuum pump for providing a suction force to the suction force applying means.

Abstract: The present invention provides surface modification methods of pancreatic islet membranes by polymeric grafting. Particularly, the present invention provides the surface modification methods that hydrophilic polymer chain is grafted onto collagen membranes of the pancreatic islets by various polymeric grafting methods instead of encapsulation of the pancreatic islets. Since the surface modification methods of the present invention minimize immunorejection without islet damage in islet transplantation, extend efficiency and survival time of the pancreatic islets by maintaining a high diffusion rate of oxygen and nutrient and reduce total volume of the pancreatic islets required for islet transplantation, they can be effectively used for transplantation of the pancreatic islets.

Abstract: An ink-jet printing apparatus that uniformly coats an alignment layer of an LCD device is provided. The ink-jet printing apparatus includes a head where the head has a head body and a supply pipe disposed inside the head body. The supply pipe allows the passage of a material through the head. The head also includes a nozzle and a foam removing means. The nozzle is in fluid communication with a portion of the supply pipe which discharges the material. The foam removing means is disposed in the nozzle and dissipates foam in the material.

Abstract: A device for washing an inkjet head and an inkjet printing system having the same is provided. The device includes a bath which holds a washing solution and a wiping device disposed above the bath. The wiping device has a holding portion and an elastic wiper coupled with the holding portion. The elastic wiper is movable with respect to the holding portion, thereby permitting easy removal of alignment material from a nozzle on the inkjet head and cleaning of the elastic wiper.

Abstract: A cosmetic case is structured such that a rotary body (3) having a brush (2) attached thereto is installed to rotate to the upper side of a tube-type case (1) for accommodating liquid cosmetic by an insertion body (4) such that the cosmetic case is manufactured by simple-structured components to enhance economic effect, an opening (12) and a discharge opening (9) are formed in the form of a single line in a body formed with the rotary body (3) such that the liquid cosmetic is smoothly discharged, lock checking parts (16 and 16a) are formed in the outer circumferential front sides of the tube-type case (1) and the insertion body (4) to easily check whether an opening (12) formed in the rotary body (3) and a liquid cosmetic discharging guide (6) formed in the upper side of the tube-type case (1) are opened or closed so that the liquid cosmetic does not leak and the cosmetic case can be maintained clean.

Abstract: The present invention relates to an apparatus and a method for realizing all-optical NOR logic device using the gain saturation characteristics of a semiconductor optical amplifier (SOA). More particularly, the invention relates to a 10 Gbit/s all-optical NOR logic device among all-optical logic devices, in which a signal transmitted from a given point of an optical circuit such as an optical computing circuit is used as a pump signal and a probe signal.

Abstract: Disclosed is a composition for preparing an organic insulator, the composition comprising (i) at least one organic-inorganic hybrid material; (ii) at least one organometallic compound and/or organic polymer; and (iii) at least one solvent for dissolving the above two components, so that an organic insulator using the same has a low threshold voltage and driving voltage, and high charge carrier mobility and Ion/Ioff ratio, thereby enhancing insulator characteristics. Further, the preparation of organic insulating film can be carried out by wet process, so that simplification of the process and cut of cost are achieved.

Abstract: A liquid cosmetic case in which a supporting cap (31) to which a brush is (30) fixed is fixed to the upper side of a tube-shaped container (1) that stores liquid cosmetic and is coupled with a discharger (10) closed after discharging liquid cosmetic and a cap (40) is thread-coupled with the upper side of the tube-shaped container (1) so that the discharger (10) coupled with the supporting cap (31) ascends and descends by opening and closing the cap (40). When the cap (40) ascends, a ring-shaped step (5) in the upper end of a liquid supplying container (6) is opened so that a through hole (12) and a liquid guiding passage (11) formed by an inner protrusion wheel step (7) are connected to a discharge hole (12) and that the liquid cosmetic in the tube-shaped container (1) is discharged to the brush (30).

Abstract: A method of fabricating a thin film transistor, in which source and drain electrodes are formed through a solution process, thus all stages which include formation of electrodes on a substrate, formation of an insulator layer, and formation of an organic semiconductor layer are conducted through the solution process. In the method, the fabrication is simplified and a fabrication cost is reduced. It is possible to apply the organic thin film transistor to integrated circuits requiring high speed switching because of high charge mobility.
