  • Patent number: 9979039
    Abstract: Disclosed are novel configurations of Direct Carbon Fuel Cells (DCFCs), which optionally comprise a liquid anode. The liquid anode comprises a molten salt/metal, preferably Sb, and a fuel, which has significant elemental carbon content (coal, bio-mass, etc.). The supply of fuel is continuously replenished in the anode. In addition, a stack configuration is suggested where combining a large number of planar or tubular fuel elements.

  • Patent number: 9673016
    Abstract: Disclosed is a micro-electron column including nanostructure tips each of which has a tubular, columnar, or blocky structure ranging in size from several nanometers to dozens of nanometers. In the micro-electron column, the nanostructure tips can easily emit electrons because a high electric field is generated at the end of the nanostructure tips when a voltage is applied to the nanostructure tips, and an induction electrode is disposed between the electron emitter and a source lens so as to help electrons emitted from the electron emitter to enter an aperture of a first lens electrode layer of the source lens, thereby realizing improved performance of the micro-electron column. In the micro-electron column, the size of the nanostructure tips may be larger than that of the aperture of a source lens.

  • Patent number: 9196454
    Abstract: Disclosed herein is a microcolumn with a double aligner. The microcolumn is configured such that when an axis of an aperture of a limiting aperture is spaced apart from an original path of a particle beam, the path of the particle beam can be effectively compensated for in such a way that the path of the particle beam is aligned with the axis of the aperture of the limiting aperture by the double aligner. The microcolumn includes a source lens. The source lens includes at least two aligner layers which compensate for the path of the particle beam.

  • Patent number: 7682851
    Abstract: An organic light emitting display and a manufacturing method thereof include an improved encapsulation layer. The encapsulation layer of the organic light emitting display includes an organic layer uniformly covering bank portions and light emitting areas on a substrate; and an inorganic layer formed thicker on the light emitting areas than on the bank portions. In the organic light emitting display, the inorganic layer is thick on the light emitting area in which a sealing ability is required and the bank portion is thin in order to provide flexibility. Therefore, the encapsulation layer can be formed more easily compared to an encapsulation layer on a device in which the organic layer and inorganic layer are alternately formed at least 10 times.

  • Patent number: 7656498
    Abstract: A method of manufacturing a multi-display panel comprises mounting a plurality of display elements on a substrate, covering the substrate and the display elements with a glass cover having walls for partitioning each of the display elements; and cutting the substrate and the glass cover along the walls and separating the display elements to respectively form image units. Thus, the width of a connection portion between the image units is less than half of that in the conventional art and a display image formed by two separate images looks natural.
