  • Patent number: 7466967
    Abstract: A communication system that can improve communication quality by accurately re-creating reproduction timing at the receiving end even at the time of receiving VBR data or in the case of the occurrence of a packet loss. A send rate recognition section recognizes a send rate from a time stamp. A memory stores data. A dummy data addition section adds dummy data for correcting the difference between a read rate set for reading out data from the memory and the send rate to the data written to the memory. A read clock generation section generates a read clock which is equal to the read rate. A dummy data removal section removes the dummy data from the data read out from the memory on the basis of the read clock.

  • Patent number: 7326473
    Abstract: An organic electroluminescent (EL) device comprising at least one luminescent layer of an organic compound, the luminescent layer being positioned between a cathode electrode and an anode electrode opposed to the cathode electrode, and an organic layer positioned adjacent to the cathode electrode, in which the organic layer is constituted from an organic metal complex compound containing at least one of alkali metal ions, alkali earth metal ions and rare earth metal ions, and the cathode electrode is constituted from a metal capable of reducing the metal ion in the complex compound, in vacuum, to the corresponding metal. The cathode electrode can be formed from a low cost and stable metal which is well-known as the wiring material. The EL device ensures a diminished energy barrier in an electron injection from the cathode electrode into the luminescent layer, a lowered driving voltage, and a high efficiency and luminescence.

  • Publication number: 20050106419
    Abstract: An organic electroluminescent device includes an anode electrode layer, a cathode electrode layer opposed to the anode electrode layer, and a luminous layer containing an organic compound disposed between the anode electrode layer and the cathode electrode layer. An excitation state of the organic compound in the luminous layer is created upon a hole injection from the anode electrode layer, and an electron injection from the cathode electrode layer, thereby causing light emission in the organic electroluminescent device. An electron-accepting material is provided in at least one hole transportation layer capable of transporting holes injected from the anode electrode layer disposed between the anode electrode layer and the cathode electrode layer, and the electron-accepting material is positioned at a site which is not adjacent to the anode electrode layer.

  • Publication number: 20040062525
    Abstract: A video processing system which realizes high efficiency and improved service quality in video production, including high-speed extraction of scenes related to a particular subject and compilation of a personalized video product. Video recording units are placed along a given course, each of which stores video of moving objects that is captured by a fixed camera, together with time stamps that indicate at what time each part of the video was taken. At checkpoints on the course, time measurement units measure checkpoint passage time of every passing moving object and store checkpoint time records including the measured checkpoint passage times and identifiers of individual moving objects. A video authoring unit searches the stored video data to find and extract scenes of a particular moving object, using the checkpoint time records in association with time stamps in the video data, and compiles the extracted scenes into a personalized video product.

  • Patent number: 6589673
    Abstract: An organic electroluminescent device includes at least one luminescent layer, constituted from an organic compound, provided between a cathode electrode and an anode electrode opposed to the cathode electrode; and an organic compound layer doped with a metal capable of acting as an electron-donating dopant, the organic compound layer being disposed as a metal doping layer in an interfacial surface with the cathode electrode. An emission spectrum of light emitted from the organic electroluminescent device is controlled by varying a layer thickness of the metal doping layer. Alternatively, the organic compound layer can be doped with an electron-accepting compound, disposed as a chemical doping layer in an interfacial surface with the anode electrode on the luminescent layer side; wherein an emission spectrum of light emitted from the organic electroluminescent device is controlled by varying a layer thickness of the chemical doping layer.
