  • Patent number: 6212208
    Abstract: In a video/audio coding and multiplexing method, coding of multimedia data including video data and audio data is implemented as a software program operating on a multitask operating system, and video/audio coded and multiplexed information in which video/audio synchronization is realized in specified time units is obtained. In this method, coded video information and coded audio information are temporarily stored in a video buffer and an audio buffer, respectively. A video/audio synchronization means creates time and information using video block rate information which is created on the basis of the coded video information and stored with the coded video information. According to the time information, a coded video read-out means and a coded audio read-out means read the coded video information and the coded audio information from the respective buffers, and the video/audio synchronization means performs video/audio multiplexing.

  • Patent number: 5814815
    Abstract: An electrostatic potential in a vacuum in the vicinity of a focused electron beam of a direct wave formed on an optical axis of a back focal plane of an objective lens used in an electron microscope can be externally controlled. Therefore, the electrostatic potential is controlled by supplying an electric potential to a ring-shaped electrode from the outside. The outer sides of the electrode are interposed between both of insulators and conductors so as to shield the electrostatic potential against the outer side of a ring, whereby a phase shift is supplied only to an electron beam that passes through the inside of the ring. A phase-contrast electron microscope can be realized which includes a phase plate corresponding to an electron beam, which is capable of observing a phase object with contrast.

  • Patent number: 5099114
    Abstract: An optical wavelength demultiplexer including an optical conversion device which converts a difference in wavelengths of a plurality of input signals into a difference in spatial power distribution of the input light signals, and a pattern recognition element for recognizing patterns of the spatial power distribution and taking out output signals. At the output portion of the optical conversion device, spatial power distributions are formed which are different for different wavelengths. After converting the spatial power distributions by the pattern recognition element into electrical signals, pattern recognition of the signals is performed to regenerate the original input signals with their respective wavelengths. The optical conversion device uses a diffractive grating or a combination of an optical multimode circuit, an optical multimode fiber, and a plurality of optical wavelengths.
