  • Patent number: 6175399
    Abstract: A reflective type liquid crystal display device in accordance with the present invention includes a reflector film having excellent polarization preservation properties and an anisotropic diffusing film for diffusing only the light polarized in a particular direction. The anisotropic diffusing film is composed of a complex of liquid crystal and a polymer and selectively diffuses incident light. If a liquid crystal layer composed of dichroic dye and liquid crystal is employed, it becomes possible to carry out high contrast display with the anisotropic diffusing film and the reflector film and to prevent reflections of nearby objects appearing on the screen.

  • Patent number: 6166676
    Abstract: In a correlating device, two switched-capacitor-type analog signal integrators are connected in cascade. The analog signal integrator in the first stage samples an analog input voltage at a predetermined cycle, determines the sign of the sampled value according to a binary-code sequence, integrates the sampled value, and outputs the resultant value. The analog signal integrator in the next stage samples an input voltage at a reset cycle of the analog signal integrator in the first stage, integrates the sampled value, and outputs the resultant value. This structure can prevent saturation of the correlating device without decreasing the gain of each analog signal integrator to a greet degree even when the sequence length becomes longer.

  • Patent number: 6163334
    Abstract: A conventional image forming device having a plurality of image optical scanning recording sections has had a drawback of being incapable of correcting printing positions of the image optical scanning recording sections with high precision by using a small-scale circuit. In the case of an image forming device of the present invention, a variable clock generator 114 having a voltage control oscillator (VCO) 114a is provided therein as reference clock signal generating means of laser control system of each of image optical scanning recording sections (LSU) for cyan, yellow, and magenta. By so doing, during an invalid printing period prior to a valid printing period, frequencies of the reference clock signals of the LSUs for cyan, yellow, and magenta are adjusted in accordance with offsets of printing start positions of these LSUs with respect to that of the LSU for black, so that printing offsets are eliminated.

  • Patent number: 6160636
    Abstract: An original is moved by a feed motor so as to read the original by the combination of a light source and a CCD. The image information thus read is stored into the memory. The image information stored in the memory is sent out via a modem to the phone line. The amount of data stored in the memory is detected: if the amount of data exceeds the first predetermined amount, the speed of movement of the original is gradually reduced while if the amount of data becomes equal to or smaller than a second predetermined amount which is smaller than the first predetermined amount, the speed of movement of the original is gradually raised.

  • Patent number: RE36987
    Abstract: In signal processing circuitry using active devices, non-linearity of the device causes distortion of pure tones and the generation of intermodulation products for more complex signals. The transfer characteristics of such active devices may be considered as the accumulated characteristics of input and output filter stages separated by a non-linear region. To compensate for non-linearities and reduce intermodulation products, a drive circuit comprises pre- and post-correction filters separated by a compensating amplifier. The frequency response of the pre-correction filter corresponds to that of the input filter stage but is reversed in the frequency spectrum; with conventional I.F. the transfer characteristic of the amplifier and frequency response characteristic of the post-correction filter are the respective complements, of those of the non-linear region and pre-correction filter.
