  • Patent number: 6417898
    Abstract: An active matrix substrate as one of substrates constituting a liquid crystal panel of a liquid crystal display device is made of a piece of substrate produced by connecting a plurality of small active matrix substrates side by side, and has color filters formed thereon. With this structure, when each of the small active matrix substrates has a maximum area obtainable by a conventional production line, a counter substrate disposed opposite to the active matrix substrate is larger than the maximum size producible by the conventional production line. However, since the color filters are formed on the small active matrix substrates, it is not necessary to newly provide a color filter production line corresponding to the larger counter substrate. Since new facility investment is not required, it is possible to provide a large-area liquid crystal display device at a low price.

  • Patent number: 6269165
    Abstract: The feedback caused between the output and the input of an amplification path is reduced by providing a delay in the amplification path, passing through the amplification path a signal having an auto-correlation function which is substantially a delta function, correlating the said signal before being delayed in the delay with the signal after being delayed in the delay to produce a plurality of correlation coefficients, modifying the signal in the amplification path to provide a modified signal, the modification being provided by a transversal filter controlled by the said plurality of correlation coefficients, and combining the modified signal with the signal in the amplification path so as to reduce the effect of the feedback.

  • Patent number: 6256107
    Abstract: Communications devices connect a plurality of digital copying machines. One of the copying machines is used to search among the other copying machines for those whose processing functions match conditions and priorities regarding image processing, post-processing, size of paper, and functions set by the operator. Those machines that match the conditions and priorities set by the operator are registered as being capable of allocation processing operations. Thereafter, the current availability of the registered digital copying machines is checked, and an outputting job is allocated, and image data is transferred, to available ones of the digital copying machines, thereby causing them to perform an allocation processing operation. Therefore, by setting the conditions and priorities for obtaining hard copies as desired by the operator using one digital copying machine, the capable and available other digital copying machines are selected and caused to perform an allocation processing operation.

  • Patent number: 6251948
    Abstract: Tri- and tetra-substituted guanidines which exhibit a high binding affinity to phencyclidine (PCP) receptors and, more preferably, low affinity to the brain sigma receptors. These guanidine derivatives act as non-competitive inhibitors of glutamate induced responses of the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert neuroprotective activity and are useful in the therapeutic treatment of neuronal loss in hypoxia, hypoglycemia, brain or spinal cord ischemia, and brain or spinal chord trauma as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.

  • Patent number: 6240206
    Abstract: An image processing apparatus of the present invention is provided with a region separating section and an automatic adjusting section. The region separating section, upon receiving a reference document having a specified ratio of a character region, a photographic region, and a spot region, recognizes and separates the each region of the received document from one another. The automatic adjusting section (1) counts the number of pixels in each of the separated regions and (2) uses the number of pixels thus counted to change a density conversion table, a filter, or a region separation table so as to adjust the separated state of each region such that the number of pixels thus counted is substantially equal to the number of pixels of the region separation state, thereby improving the accuracy of region separation of the image processing apparatus and the image quality of a final image after it is processed with image processing.
