  • Patent number: 6456571
    Abstract: A magneto-optical recording medium comprising a recording magnetic layer made of a perpendicularly magnetized film and a multilayer reproducing film, wherein the multilayer reproducing film has two reproducing magnetic layers which are in a in-plane magnetized state at room temperature and shift to a perpendicularly magnetized state with a rise in temperature and an in-panel magnetized layer disposed between the two reproducing magnetic layers, which is in an in-plane magnetized state from room temperature to a Curie temperature and has a lower Curie temperature than the recording magnetic layer and the reproducing magnetic layers.

  • Patent number: 5956108
    Abstract: Liquid crystal panels are connected to one another with at least one thermoplastic bonding agent. The thermoplastic bonding agent has the same refractive index as the refractive index of two glass substrates respectively serving as a TFT substrate and a CF substrate forming each liquid crystal panel. The liquid crystal panels are heat-pressed to a reinforced substrate through the thermoplastic bonding film which is made of, for example, a thermoplastic polymer. According to this arrangement, the thermoplastic bonding film does not lose its volume when the liquid crystal panels are heat-pressed to the reinforced substrate. Thus, unlike a conventional method where the CF substrate forming the liquid crystal panel is pulled toward the reinforced substrate side, a uniform cell gap can be secured.

  • Patent number: 5773175
    Abstract: A photosensitive body for electrophotographical use has a conductive base body and a marking area provided thereon. The maximum surface roughness of a photosensitive layer provided right on the marking area is specified not to exceed 2.5 .mu.m. And also, a ratio of the optical reflective index of the marking area to the optical reflective index of the non-marking area is specified to be in a range of 0.3 to 0.7. In this manner, even when the photosensitive layer is thin (not exceeding 25 .mu.m), it is possible to prevent problems such as inadequate cleaning and toner falling. Hence, it is possible to offer a photosensitive body for electrophotographical use which can constantly produce high quality copied images.

  • Patent number: 5751382
    Abstract: The present invention provides a liquid crystal display device including a pair of electrode substrates and a display medium sandwiched between the electrode substrates and including a polymeric wall and liquid crystal regions at least partly surrounded by the polymeric wall. In this liquid crystal display device, the polymeric wall is tightly attached to both the electrode substrates. Furthermore, the invention also provides a method for producing a liquid crystal display device including a pair of electrode substrates, at least one of which is transparent, and a display medium including a polymeric wall and liquid crystal regions at least partly surrounded by the polymeric wall and sandwiched between the electrode substrates.

  • Patent number: 5748776
    Abstract: The present invention is intended to exactly extract a feature-region along its contour line without erroneously extracting any moving object other than the feature-region. An extraction signal from a feature-region main-portion extracting circuit is sent to a small region eliminating circuit whereby an erroneously extracted small region is detected and eliminated as an erroneously extracted noisy portion. The small region eliminating circuit compares a small region with four predetermined detection patterns, discriminates it as a region other than the feature (face)-region if no match is found and causes a center pixel of a window of 3.times.3 pixels to have a logical value of zero. An output of the small region eliminating circuit is sent to a blank filling circuit which compares its input with four predetermined detection patterns, discriminates it as a face-region if a match is found and makes a central pixel of a window of 13.times.13 pixels have a logical value of 1.

  • Patent number: 5745005
    Abstract: A communication device which is capable of automatically discriminating whether a received signal is a carrier-wave-modulated signal or a single-pulse-modulated signal and obtaining a corresponding demodulated signal, thereby reducing a burden to a user in using the device. The device comprises a demodulating circuit for demodulating a carrier-wave-modulated signal, a demodulating circuit for demodulating single-pulse-modulated signal, a switch circuit for selecting either of two demodulating circuits and a carrier detecting circuit for detecting the presence or absence of a carrier-frequency component of the carrier-wave-modulated signal, characterized that the switch circuit selects an output of the demodulating circuit for the carrier-wave-modulated signal when the carrier of the carrier-wave-modulated signal is detected by the carrier detecting circuit.

  • Patent number: 5740322
    Abstract: A fuzzy neural network system includes a learning function. The learning is performed by determining degrees of coincidence of rules from combinations of membership functions for realizing fuzzy rules, constructing a network based on the number of input and output items, in such a manner as to produce output in conformity with the degrees of coincidence, to thereby properly simulate relations between input and output as to sample data represented by a subject input pattern and an output pattern corresponding thereto. The system further includes a fuzzy rule setup portion for programming fuzzy rules created by engineers into the fuzzy neural network, a fuzzy rule extracting portion for extracting each fuzzy rule from the network after a learning period, and a degree-of-importance extracting portion which extracts, for each input, a respective contribution ratio of each input on each output in the network, after a learning period.
