  • Publication number: 20070058224
    Abstract: An image processing apparatus includes an image reading unit that reads an image of a surface of a document to acquire image data and a document type setting unit that receives input of setting of a document type of the document. A color-correction-constant changing unit changes a color correction constant to be used in an image processing based on the set document type. An image-data converting unit converts the image data to an image data in a first color space that is a common color space by applying the image processing based on the color correction constant to the image data.

  • Patent number: 5348424
    Abstract: A novel method to construct a reinforcing block in an embankment is provided, wherein a core rod to which a protrusion is molded on the tip, is preset inside a hollow rotating shaft with drilling and agitating blades affixed around its circumference, but with the protrusion on the core rod exposed at the front of the shaft. This drilling and agitating shaft rotates and bores into the earth while simultaneously mixing the soil so agitated with a fixing agent; then at a specified depth, the rotating shaft is withdrawn leaving the core rod to remain anchored in the soil while the fixing agent continues to discharge from the end of the hollow rod; and when the hollow rod is completely removed, a reinforcing block is intact within the soil and the tail end of the core rod exposed on the surface of the banking is directly or indirectly affixed to this surface.
