  • Publication number: 20080098016
    Abstract: The present invention provides a database system capable of dealing with dynamic changes in an event that vary continuously with time. A database system outputs a retrieval output from data in response to a user's retrieval request on the basis of a retrieval logic. The retrieval logic is allowed to evolve on the basis of a logical model. This logical model establishes a general relationship which leads results from conditions relating to a group of events that are dealt by a data group. Moreover, a database system optimizes a data structure on the basis of the logical model. The logical model can be transferred in a separated manner from the specific data contents of the data group. Therefore, the logical model can be exported to another database system of the same kind, and also imported from another data base system of the same kind.

  • Publication number: 20080088048
    Abstract: In an injection molding machine, a hydraulic actuator and a hydraulic pump are arranged close to each other to make a hydraulic pipe as short as possible so as to improve maintenanceability and improve reliability of a hydraulic drive part. The injection molding machine has one movable part configured to be movable with respect to a body frame. The hydraulic actuator and the hydraulic pump unit are fixed to the movable part. The hydraulic pump unit supplies a generated fluid pressure to the hydraulic actuator. The hydraulic pump unit and the hydraulic actuator are connected by a hydraulic passage provided to the movable part. The hydraulic actuator, the hydraulic pump unit and the hydraulic passage are moved with a movement of the movable part.

  • Patent number: 7167273
    Abstract: An image processing apparatus providing a halftoning process such as error diffusion prevents an image contour distortion, as follows: data in an image to be processed is used to partially extend the image to be processed. Then error diffusion or the like is employed to provide a halftoning process. The extension is removed to obtain image data. A dot generation delay can be prevented that would otherwise be introduced such as when an extension-free image is halftoned.

  • Publication number: 20060263120
    Abstract: This invention enables an image forming apparatus to perform highly precise misregistration detection without causing increased downtime or increased cost. For this, the image forming apparatus according to the invention comprises a detection unit for detecting a misregistration detection pattern formed on an endless belt. The employed misregistration detection pattern includes a first pattern array formed with a misregistration detection color or a reference position color, and a second pattern array formed with a misregistration detection color or a reference position color. The misregistration detection pattern is configured in a way that the first pattern and the second pattern have different shapes, and that the color order of the first patterns in the first pattern array and the color order of the second patterns in the second pattern array are different.

  • Patent number: 7127102
    Abstract: From profiles of an input color space and an output color space, the specific color data on respective color spaces are obtained, and a color space compression parameter is set based on each specific color data obtained. In other words, the color space compression parameter for appropriately converting data within the input color space into data within the output color space is derived from each specific color data. The color space compression processing (color matching) is performed on an absolute color space using the derived color space compression parameter so that it becomes possible to perform at a higher speed an appropriate color matching that takes into account the characteristics of the input color space and the output color space.

  • Patent number: 7006105
    Abstract: The gray axis of an input apparatus is shifted so as to match the gray axis of an output apparatus. Each data on a plane of equal lightness located in the Gamut of the input apparatus is shifted in the same direction in accordance with the shift of the gray axis by an amount of shifting smaller in proportion to greater distance from the gray axis. Therefore, the image is not governed by the chromaticness in the shifting direction even if the gray axis is shifted. Points located outside the Gamut of the output apparatus is compressed-converted into points within the Gamut (surface) where color difference is minimized while maintaining the lightness. A desired image is reproduced without inversion in the lightness after Gamut compression between data.
