  • Patent number: 5968132
    Abstract: Image data communicating apparatus and communication data quantity adjusting method in an image data communication system suitable for use when image data is transferred in a network environment. Image data is transferred in a most suitable quantity based on traffic of a network to avoid an effect on other services provided by the network. The apparatus has a data transmitting unit for transmitting image data to another image data communicating apparatus, a traffic detecting unit for detecting traffic of the network, and a communication data quantity adjusting unit for initially setting a transmittable number of image transferring frames on the basis of the detected traffic, and for automatically adjusting the quantity of data communication in the data transmitting unit on the basis of changing traffic on the network by altering the set number of frames.

  • Patent number: 5136153
    Abstract: An image forming apparatus for irradiating an image light on a photosensitive recording medium having at least one photosensitive wavelength range on the basis of an image information to thereby form an image on the photosensitive recording medium, comprising a semiconductor laser for emitting an image light or a thermal cathode for emitting thermoelectrons having the image information, a photomultiplier or microchannel plate for converting the image light or the thermoelectrons into secondary electrons while the image forming information is kept, and multiplying the secondary electrons, and a fluorescent screen for converting the multiplied secondary electrons into an intensified image light. The intensified image light may be supplied on a photosensitive recording medium while the image forming information is kept, thereby forming an image on the photosensitive recording medium.
