  • Patent number: 7422821
    Abstract: A flat connecting plate designed for solid oxide fuel cell to improve the uniformity of fluid flow rate comprising a series of parallel ribs and grooves formed by the spaces between the ribs, the lengths of the ribs vary in accordance with the variation of the edge at proximity of fluid inlets, the widths of the grooves reduced in sequence from edges to center of the connecting plate, a series of diamond blocks placed at proximity of fluid outlet symmetrical to the center line of the connecting plate, and/or a series of fluid guide plates formed in parallel at the middle of two fluid inlets.

  • Publication number: 20080096089
    Abstract: A method for the fabrication of a mesoporous metal electrode in a non-liquid crystalline phase was tested. Specifically, there was tested the efficacy of the method for the fabrication of a mesoporous metal electrode which comprises forming the mesoporous metal electrode on a substrate by chemical or electrochemical reduction of a mixture comprising a solvent, a structure-directing agent, and a source of a metal, characterized in that the mixture is maintained in a non-liquid crystal phase. Furthermore, the usefulness of the mesoporous metal electrode thus prepared from the non-liquid crystalline phase was also tested. The mesoporous metal electrode prepared from the non-liquid crystalline phase had a large surface area, and a roughness factor thereof was controlled by charges passed during electroplating. The method made it possible to fabricate the mesoporous metal electrode in the non-liquid crystalline phase, even more flexible than a liquid crystalline phase.

  • Publication number: 20060190976
    Abstract: Provided are an apparatus and method for searching a start position of a broadcast program. According to an embodiment of the present invention, a received broadcast program is recorded in a recording medium while being output as video and audio. If a new broadcast program is started, position information regarding a start part of the new broadcast program is stored in a memory. Thus, a current broadcast program is reproduced from a start part by searching a start position of the current broadcast program recorded in the recording medium with reference to stored position information. A determination on whether the new broadcast program is started is done on the basis of Electronic Program Guide (EPG) information or a change in audio and video signals. Accordingly, it is possible to quickly search and reproduce a start part of a broadcast program which is currently recorded.

  • Publication number: 20060038765
    Abstract: A liquid crystal display device has facing substrates, pairs of data lines, gate lines intersecting the data lines to define pixel areas, pixel electrodes formed in the pixel areas, a gate driver, a source driver and a latch circuit. Each pair of data lines includes first and second data lines adjacent each other. The gate driver applies a gate signal to the gate lines, and the source driver outputs data signals to the first and second data lines. The latch circuit stores a data signal output from the source driver and transmits relevant data signals to odd and even pixel electrodes formed between the first and second data lines. During high-speed operation, the data signal from the source driver is bisected and applied as an odd and even data signal to two neighboring data lines at certain time intervals.

  • Publication number: 20050142486
    Abstract: The present invention relates to new polymers and use of such polymers as a resin binder component for photoresist compositions, particularly chemically-amplified positive-acting resists that can be effectively imaged at short wavelengths such as sub-200 nm, particularly 193 nm. Preferred polymers of the invention are terpolymers and tetrapolymers that can exhibit good adhesion to underlying inorganic surfaces such as SiON and Si3N4 surfaces and contain repeat units with pendant moieties having heteroatom substitution.
