  • Patent number: 7564596
    Abstract: Means for detecting scanning positions of first and second recording heads is provided for detecting that the first recording head is opposed to a recording inhibition area (in which an imaging material is not mounted) on a drum 1, based on an output from the detection means. While the recording head is in the recording inhibition area, correction data for the second recording head is read from a correction data memory and transferred to a submemory in an FPGA for image processing. The second recording head reads the correction data from the submemory. Correction data can be read in parallel.

  • Publication number: 20090179981
    Abstract: In an image recording apparatus using an image recording medium which generates a gas when irradiated with a light beam, the gas and the like are prevented from drifting into a space between the image recording medium and a drum and contaminating the back surface of the image recording medium. The gas is effectively prevented from drifting to the back surface of a plate P by setting a relative positional relationship of an extending direction of each suction groove L, an attaching position of the plate P and an air blowing direction so that unclosed regions, not closed by the plate P, of suction grooves L formed in a drum surface 31 do not occur downstream in a gas moving direction.

  • Publication number: 20080263683
    Abstract: Triple Tg (megsin/RAGE/iNOS-Tg) was created by crossing megsin-Tg with RAGE/iNOS-Tg. The megsin/RAGE/iNOS-Tg develops marked pathologies of diabetic nephropathy unfound in conventional models at early stages, and various pathological conditions such as glomerular hypertrophy were observed uniformly in the megsin/RAGE/iNOS-Tg mice. In addition, it was also found that animals exhibiting these symptoms were useful as a disease model animal for diabetic nephropathy. Specifically, the disease model animals of the present invention overexpress the megsin gene, a gene encoding the receptor for advanced glycation end-products, and an inducible nitric oxide synthase gene. As a result, accompanying kidney function disorders of glomerular failure develop at early stages.

  • Patent number: 7436540
    Abstract: A control part comprises a division location setting part for setting a division location based on an image data; a scan start position setting part for setting scan start positions of recording heads based on the division location; an image data division part for dividing an image data by the division location; and a head movement control part for controlling movement of the recording heads. The division location setting part sets a division location in a blank area having no pixel to be recorded in the primary scanning direction, in the case of publication printing, in a center margin area between page data. Since the recording heads perform scanning concurrently their respective areas that are divided by the division location, no deterioration in image continuity occurs between the recording heads. This permits an image recorder, though having plural recording heads, capable of performing concurrent recordings without loss of continuity.

  • Publication number: 20080222137
    Abstract: For information about a plurality of objects with respect to which directed relation and relation weight are set, a virtual bidirectional relation is set between objects in a pair, and a weight for the virtual relation is set different from that of the predetermined relation. Then, a process to produce predetermined information about the object is carried out based on the relation.
