  • Patent number: 6459470
    Abstract: An image printer for printing images with less cross-talk between images and less image flickering is provided. A plurality of images are interleft in one or a plurality of line units and a lenticular lens is used to make it possible for each individual pixel to be distinguished. The difference in brightness between an attentional pixel and the surrounding pixels that surround this attentional pixel is taken, and a correlation value is produced, the correlation value being reduced if the difference is large and increased if the difference is small. The image printer is equipped with a pixel shape controller that makes the printed pixels smaller in a region where the correlation value is low, and makes the printed pixels larger in a region where the correlation value is high.

  • Patent number: 5434869
    Abstract: A test pattern generating apparatus for generating test patterns to test a sequential circuit having at least one memory element. The apparatus calculates, in response to a primary input applied to the sequential circuit, analog logic values for signal lines in the sequential circuit using a nonlinear function, then stores history data for the analog logic values with an inverse covariance matrix of the analog logic values. The apparatus then calculates an evaluation value according to the degree of variance between the analog logic values and the history data. A primary input setting unit is used for producing a next primary input which provides a maximum evaluation value from the evaluation value obtained from the present primary input. inputs produced by the primary input setting unit.

  • Patent number: 5341315
    Abstract: A test pattern generation device for producing test pattern signals for testing a preselected digital circuit includes a dominant pattern signal generator and a subservient pattern signal generator. When a first dominant pattern signal (0,0,0,0,0) is generated, five subservient pattern signals (1,0,0,0,0), (0,1,0,0,0), (0,0,1,0,0), (0,0,0,1,0) and (0,0,0,0,1) are generated, each being unit Hamming distance from the dominant pattern signal. The subservient pattern signals are sequentially applied to a simulator carrying a hypothetical digital circuit for producing a controllability cost CCO.sub.f and a continuous cyclic logic value CV.sub.f at a preselected line G.sub.f in the digital circuit for each subservient pattern signal. A cost generator produces an evaluation cost CT.sub.f by the use of the controllability cost CCO.sub.f and the continuous cyclic logic value CV.sub.f for each subservient pattern signal.

  • Patent number: 5076653
    Abstract: An infrared optical fiber is disclosed which has a composition ratio of silver chloride and silver bromide in the range of 30 to 70 percent by weight of silver chloride, and has a diameter of 0.5 mm or less. The infrared optical fiber has great mechanical strength, so that it does not burn because of degradation in the laser beam transmission capability, even after 2,000 times of repetitive bending with a curvature radius of 20 mm, which is the condition necessary for use within the interior of a body, and it exhibits excellent radiant optical characteristics. In particular, an infrared optical fiber with a diameter of 0.35 mm or less is preferred, because such an infrared optical fiber withstands over 10,000 times of repetitive bending under the same condition as above and can therefore be repeatedly used many times.
