  • Patent number: 9077914
    Abstract: This invention can generate printed matter on which a multi-valued discrimination image of three values or more cannot be visually confirmed under ordinary light but can be visually confirmed via an infrared camera under infrared light. To this end, a holding unit holds items of color information C1, C2, and C3 each indicating usage amounts of printing materials of three types, used by a printing apparatus, which have a color difference under visible light not more than a pre-set threshold, and which have different infrared light ray absorption rates. When a latent image generating unit generates infrared light ray latent image data of three tones, a discrimination image data generating unit decides one color information item Ci (1?i?3) held by the holding unit, and outputs the decided Ci to an output unit which outputs the received pixel values to the printing apparatus.

  • Patent number: 8961178
    Abstract: A dental implant comprises a titanium member composed of a sintered body made from titanium or titanium alloy; and a ceramic member composed of oxide-based ceramic, and the ceramic member fixed to the titanium member. The titanium member has a recess, and the ceramic member has a protrusion coupled to the recess and pores, and the titanium member covers the protrusion of the ceramic member. The protrusion has a cross-sectional area increasing portion whose cross-sectional area increases toward a dead-end portion of the recess in a direction away from a base end of the protrusion. The titanium member is firmly fixed and joined to the ceramic member in a state that a part of the titanium or the titanium alloy is penetrated into the pores of the protrusion of the ceramic member.

  • Patent number: 8922839
    Abstract: A array including array elements in a number smaller than the minimum number of pixels, having values larger than Th_c, and a plurality of array elements having values smaller than Th_c is generated. A formation array having the same size as that of a latent image is generated from the generated array. An image obtained by replacing the pixel value at a pixel position within the first region in the latent image with the value at the pixel position in the formation array is generated as a configuration image. The pixel value at each pixel position in the configuration image, that corresponds to each pixel position in the input image, is output as the amount of a highly infrared absorbent color material used to print a pixel at this pixel position in the input image.

  • Publication number: 20140376321
    Abstract: To include a plurality of core chips to which different pieces of chip information from each other are given in advance. A first refresh command is divided into a plurality of second refresh commands having different timings from each other, and a refresh operation is performed on a core chip for which a count value of the second refresh commands and at least a portion of the chip information match each other. With this configuration, even when the second refresh command is commonly supplied to a plurality of core chips, it is possible to shift a timing for the refresh operation in each of the core chips. Therefore, it is possible to reduce a peak current at the time of the refresh operation.

  • Patent number: 8718409
    Abstract: In verification of image data of a captured image as to whether it is original one, the verification is possible even for image data subjected to a peripheral illumination correction or an exposure correction. An order information calculation unit selects a pixel set including two or more pixels based on pixel values and information on an image space of image data of a captured image, and calculates an order of magnitude between pixels in the selected pixel set. A verification data producing unit generates verification data used in verification of whether the image data has not been tampered with, based on the calculated order of magnitude. An image output unit outputs the image data and the verification data.

  • Publication number: 20140100094
    Abstract: A tool magazine that can make a long tool reasonably coexist with other tools and a machining center with the tool magazine are provided. The tool magazine has a rotatable magazine main body and plural of tool holders installed on the magazine main body. Each of the tool holders moves to a tool exchange position sequentially. A part or all of the tool holders has a capability of changing between an exchange posture that holds the tool in parallel to a rotation shaft of the magazine main body and a transport posture that holds the tool along with a plane perpendicular to the rotation shaft of the magazine main body. The tool holder capable of changing postures takes the exchange posture when it locates in the tool exchange position and takes the transport posture when it leave the exchange position. The machining center has the above tool magazine.
