    摘要: In the picture quality stabilizer for a color laser printer, changes in the gray level characteristic and the color balance caused by changes in temperature and humidity are compensated in order to stabilize the reproduced image. The apparatus includes a temperature and humidity sensor, an upper-bound correction table, a gamma correction table and a mixed color correction table, each optimized with respect to a reference environment, interpolation means for those tables, and a gray level correction means for correcting the gray level with correction coefficients obtained by the interpolation means and the mixed color correction means for compensating any failure of the color balance with the linear transformation. With this configuration, the correction coefficients are so modified as to establish a stable gray level characteristic and color balance, and a stable reproduced image can be obtained.

    摘要: A storage device includes a partition wall dividing an interior of a casing into a disk chamber and a drive chamber. Recording disks are rotatably disposed in the disk chamber. Arms, each supporting a read/write head at a distal end portion thereof are capable of exteding into the respective spaces between the recording disks through an opening of the partition wall. An actuator is mounted within the drive chamber for linearly reciprocating the arms to cause the heads to skim across recording surfaces of the recording disks. An interrupting surface is formed on a portion of the partition wall at a downstream side of the arm with respect to an air flow due to the rotation of the recording disks, for interrupting the air flow to convert a dynamic pressure of the air flow into a static pressure thereof. With this arrangement, the air is prevented from flowing back from the drive chamber into the disk chamber.

    摘要: 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.

    摘要: 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.

    摘要: 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. The exposure intensity distribution changing device substantially equalizes the sum of the exposure intensity of the pair of neighboring scan lines of the combination scan line at every section in the main scanning direction.

    摘要: 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.
