  • Publication number: 20060178074
    Abstract: A flat panel display device includes: a substrate; an electrode composed of metal; and an adhesive layer interposed between the substrate and the electrode. The electrode of the flat panel display device has excellent conductivity. The method of manufacturing the flat panel display device includes: preparing a metal substrate; forming a metal plating substrate by forming a plating mask layer on the metal substrate; forming an electrode on the metal plating substrate; separating the electrode, which is formed on the metal plating substrate, from the metal plating substrate with a cohesive layer; placing the separated electrode on another substrate using an adhesive composition; separating the cohesive layer from the electrode; and heat treating the adhesive composition to form an adhesive layer, the adhesive layer attaching the electrode to the another substrate. This method reduces the likelihood of malfunctioning electrodes being produced and leads to reduced manufacturing costs and processing time.

  • Publication number: 20060156758
    Abstract: An operating system of a liquefied natural gas ship for performing sub-cooled liquefaction of boil-off gas includes a boil-off gas compressor, a cryogenic heat exchanger connected to a refrigerator system, and a first check valve and a first pressure control valve, installed in a pipe between a liquefied natural gas phase separator and a gas combustion unit, and a second check valve and a second pressure control valve, installed in a parallel pipe connected to the pipe in parallel. The parallel pipe is connected to a pipe between the boil-off gas compressor and the cryogenic heat exchanger such that boil-off gas is supplied to an upper vapor region of the liquefied natural gas phase separator. Thus, pressure and level of the liquefied natural gas phase separator are stably controlled. Power consumption is effectively reduced, and economical efficiency is achieved by stable operating pressure and level of the liquefied natural gas phase separator.

  • Patent number: 7018259
    Abstract: Disclosed is a spacer of a flat panel display (FPD) and a method for preparing the same. The method for preparing a spacer of the present invention includes: (a) exposing a photosensitive glass to a light; (b) heat-treating the exposed photosensitive glass to crystallize it; (c) etching the crystallized glass to prepare the spacer; and (d) heat-treating the spacer under a reductive gas atmosphere. The spacer can be easily prepared by the method according to the present invention, and it has improved conductivity on its surface. A flat panel display including the spacer prepared by the method of the present invention has enhanced conductivity. Therefore, the spacer prevents secondary electron emission, spacer charging, and deviation of electron beams.
