  • Patent number: 8901206
    Abstract: The natural rubber of the present invention is natural rubber obtained by leaving standing for a prescribed period of time a hydrous coagulum obtained from a natural rubber latex to which a preservative is added and/or from a coagulum of a natural rubber latex to which a preservative is added and drying it. The natural rubber coagulum is inhibited from being changed in a molecular weight even in a standing step (aging) in a high moisture condition, whereby the natural rubber having stable mechanical properties is obtained. An isothiazoline base compound is used for the preservative. Further, a rubber composition containing the natural rubber is prepared, and a tire is produced by using the rubber composition.

  • Patent number: 8537422
    Abstract: An input of image data is received, and information of width and/or thickness of a recording medium, which receives an image representing the image data to be recorded thereon, is received. Then, a preset pressing pressure value, which is used when the image is recorded on the recording medium, is obtained based on the information of width and/or thickness, and information of image density in the reference area, which is a part of the image data, is obtained. Then, converted image density information is obtained by converting the information of image density in the reference area based on the pressing pressure value and the information of image density, and image data is generated according to the thus obtained converted image density information.

  • Publication number: 20120262556
    Abstract: The instant application describes a method for detecting crosstalk on a display surface compartmentalized into display regions by image patterns that are contained in an input image signal to a display device. The method includes steps of: displaying a first image and a second image on a display surface, the first image including first pattern images having main regions depicted with different brightness from each other and the second image including second pattern images having the main regions and sub regions depicted with different brightness from the main regions; taking an image of the display surface to obtain image data; and comparing at least one of the first and second images with the image data to detect the crosstalk. The first and second pattern images are displayed in a center region at a center of the display surface and adjacent regions adjacent to the center region.
