  • Patent number: 10180196
    Abstract: A fluid control apparatus configured to be able to reduce electric power consumption required for opening/closing operations of a fluid control valve includes a valve body and a valve seat one of which is formed of a magnetic material and the other of which includes a magnet, the valve body and the valve seat being incorporated in a fluid flow passage and movable to come into contact with or away from each other to control communication of fluid, an urging member configured to urge the valve body toward the valve seat, an electric pump for flowing the fluid in the flow passage, and a control section for effecting control to increase an output of the electric pump to a preset state when the valve body under a closed state as being in contact with the valve seat is to be opened.

  • Patent number: 9837013
    Abstract: Aspects of the present invention are related to systems and methods for compressing display non-uniformity correction data and for using compressed display non-uniformity correction data. A correction image may be compressed by fitting a data model to the correction image data and encoding the model parameter values. A correction image may be decomposed into two images: an image containing the vertically and horizontally aligned structures of the correction image and a smoothly varying image. The smoothly varying image may be compressed by fitting a data model to the smoothly varying image data. Multiple correction images may be compressed by determining eigenvectors which describe the distribution of the multiple correction images. Projection coefficients may be determined by projecting each correction image the determined eigenvectors, and an eigen-image associated with an eigenvector may be compressed. Correction data for a display may be reconstructed from parameter values stored on a display system.

  • Publication number: 20170211226
    Abstract: The present invention provides a method of manufacturing a highly functional surface-modified fibrous material with high added value, to which a novel functionality is imparted while making use of the characteristics inherent in the fibrous material, by modifying the surface of a natural fibrous material derived from an animal or a plant, or of a synthetic fiber; and a surface-modified fibrous material thereby obtained. The method of manufacturing a surface-modified fibrous material according to the invention includes attaching an inorganic material on the surface of a fibrous material by a sol-gel reaction, while allowing the fibrous material to move via an air stream. Preferably, an atmospheric-pressure low-temperature plasma is further applied to the surface of the fibrous material on the surface of which the inorganic material has been attached, while allowing the fibrous material to move via an air stream.

  • Patent number: 8505506
    Abstract: An oil pressure control apparatus includes a control valve mechanism being in communication with a pump via a first fluid passage and being in communication with a control apparatus via a second fluid passage, a third fluid passage diverging from the first fluid passage to supply oil to a predetermined portion other than the control apparatus, and a fluid passage dimension regulating mechanism including a movable member provided at the third fluid passage and including an opening for regulating a fluid passage dimension of the third fluid passage. The fluid passage dimension regulating mechanism is in communication with a fourth fluid passage diverging from the second fluid passage and biases the movable member to a side increasing the fluid passage dimension by applying the hydraulic pressure of the fourth fluid passage to the movable member separately from the hydraulic pressure of the third fluid passage.
