  • Publication number: 20160132011
    Abstract: An image forming system includes an image output device, a measurement sensor, a tone correction value generation unit, and a tone correction unit. The image output device outputs an image on a recording medium with a mixture of a plurality of basic colors based on an image data array combining the basic colors. The measurement sensor measures a reflection characteristic of at least a part of the image output by the image output device. The tone correction value generation unit generates, for each of the basic colors, a tone correction value for correcting a tone characteristic of the basic color by synthesizing a correction array forming a regular matrix based on the reflection characteristic measured by the measurement sensor and the image data array. The tone correction unit corrects an image output by the image output device with the tone correction value.

  • Publication number: 20160084864
    Abstract: A sample-processing system that improves total system processing efficiency, and reduces a sample-processing time, by establishing a functionally independent relationship between a rack conveyance block with rack supply, conveyance, and recovery functions, and a processing block with sample preprocessing, analysis, and other functions. A buffer unit with random accessibility to multiple racks standing by for processing is combined with each of multiple processing units to form a pair, and the system is constructed to load and unload racks into and from the buffer unit through the rack conveyance block so that one unprocessed rack is loaded into the buffer unit and then upon completion of process steps up to automatic retesting, unloaded from the buffer unit. Functional dependence between any processing unit and a conveyance unit is thus eliminated.

  • Patent number: 9108832
    Abstract: A cover opener for opening a cover 1a that is rotationally removed from and fixed to a reagent container 1 includes: a rotational drive unit 12 and a cover retainer 17 to retain the cover 1a by becoming engaged with a concave portion 1b provided on an upper portion of the cover 1a. A carrier 16 is driven to rotate as the rotational drive unit rotates, as well as to move in a direction of a rotational axis with respect to the rotational drive unit. Springs 19 and 20, one of which is provided between the rotational drive unit and the cover retainer, and the other between the rotational drive unit and the carrier, bias the rotational drive unit and the cover retainer or the carrier in relative fashion to move away from each other. This enables the cover of the reagent container to be reliably opened.

  • Patent number: 8728395
    Abstract: The present invention provides an automatic analyzer for analyzing blood, urine, or other samples in which, for the purpose of reducing the workload of the operator, the process of reagent replacement is automated such that the measurement operation of the analyzer need not be halted during the reagent replacement. A sample rack transfer mechanism and reagent storage/transfer mechanisms are placed on different levels of two-story structure. This configuration allows reagent replacement even when the analyzer is performing an analysis, as well as achieving size reduction of the analyzer. The automation of reagent replacement is achieved by the following: a sensor's detection of the remaining reagent amount in a reagent vessel reaching a particular value; and the analyzer's detection of a measurement request for a sample rack when necessary reagents are not present in any reagent storage mechanism of an analyzer unit.

  • Patent number: 8559058
    Abstract: An image forming apparatus outputs a proof chart in response to an instruction for calibration execution from a user and then a color measuring unit measures the colors of patches on the proof chart. A profile management unit selects, from entries in a base profile DB, a base profile in an entry that has color reproduction characteristics that are closest to the color measurement values of the patches and generates a sheet correction TRC that has an approximation to the color measurement values of the patches when the selected base profile is used. The selected base profile is used as a color conversion parameter in a color management module, and the generated sheet correction TRC is used as a tone correction parameter in a sheet-corresponding correcting unit.

  • Patent number: 8319811
    Abstract: An image forming apparatus includes an optical scanning system that simultaneously forms a group of two scanning lines extending in a main scanning direction on a surface of a photoconductive member at a prescribed scan line interval in a sub scanning direction. An exposure intensity distribution changing device is provided to symmetrically change exposure intensity distribution of two scanning lines in the main scan direction. A group of two scanning lines formed next on the photoconductive member partially overlaps with the group previously formed with displacement of a prescribed feed pitch in the sub scanning direction so that a prescribed numbers of the two scanning lines neighboring to each other of the different groups are paired to form a prescribed number of combination scan lines.
