  • Publication number: 20040058100
    Abstract: An ink jet recording sheet having high ink-absorbing ability is disclosed. A porous structure is formed inside of an ink-permeable layer of a recording sheet according to the invention. The total volume of pores having a radius ranging between 100 nm or more and 10000 nm or less is 0.06 cm3/g or more owing to the porous structure. Therefore, ink applied to the surface of the ink-permeable layer is permeated vertically through the porous structure and blurring is therefore scarcely caused. Also, an ink-absorbing layer having hydrophilic a resin has high ink-absorbing capacity. The ink permeated through the ink-permeable layer is absorbed in the ink-absorbing layer and fixed, so that it is not diffused in the recording sheet. Therefore, the recording sheet has high ink-absorbing ability and is therefore free from blurring and enables high print density also when it is used for printing in an ink jet system.

  • Patent number: 6662090
    Abstract: The present invention provides a protective maintenance service system capable of raising an alarm for the replacement of a part when the degradation of an inspection required part reaches the prescribed criteria of replacement. Of the respective inspection required parts stored in the vehicle inspection parts database for the respective vehicles stored in the vehicle database provided by a business unit in advance, the time of part replacement is determined on the basis of the data detected by a part condition sensor for a part having a part condition sensor, and on the basis of the time, which is obtained from the service life compensated with an actual service environment, for a part without a part condition sensor.

  • Patent number: 6649232
    Abstract: A recording sheet for use with inkjet printers which achieves high color density while being free of bleeding is provided. The recording sheet has an ink-receiving layer and an ink permeable layer arranged on a surface of the ink-receiving layer. The ink permeable layer includes a filler, a surfactant, and a binder. The surfactant includes a fluorosurfactant having perfluoro-alkyl groups in its chemical structure. The ink permeable layer is made hydrophobic as well as lipophobic since hydrophilic groups on the surfaces of the filler particles will be covered by perfluoro-alkyl groups of the fluorosurfactant. This prevents aqueous ink added an organic solvent from dispersing within the ink permeable layer. The ink permeable layer includes a binder containing a water-insoluble resin having a hydroxyl value of 4 or higher (mgKOH/g) to lower the affinity to the ink.

  • Patent number: 6616992
    Abstract: The recording sheet has an ink-receiving layer and an ink permeable layer. The ink permeable layer is arranged on a surface of the ink-receiving layer and includes a filler and a binder. The binder contains as a primary component a water-insoluble polyester resin having a high hydroxyl value in the range of 25 to 65. The ink permeable layer 13 has a significant ink phobicity. The ink permeable layer does not contain a surfactant and is low lipophilic. Thus, when it receives ink containing an organic solvent, the ink does not disperse within the ink permeable layer to provide printed images without bleeding.

  • Publication number: 20030076523
    Abstract: Print picture quality of an image processing apparatus is diagnosed, thereby enabling whether it is necessary to perform maintenance of the image processing apparatus or not to be monitored even from a remote location. For this purpose, a system for diagnosing the print picture quality of the image processing apparatus has: transfer means for transferring test data which is necessary for a test print from a server to the image processing apparatus; image input means for scanning an image which was print-outputted by the image processing apparatus in accordance with the test data and inputting image data; discriminating means for examining the image data and discriminating the print picture quality of the image processing apparatus; and notifying means for controlling whether the server is notified of the discrimination result in the discriminating means or not in accordance with this discrimination result.

  • Publication number: 20020178033
    Abstract: An automobile insurance premium setting system is provided in which a premium amount may be appropriately set according to driving states of an insurant's automobile. A basic premium calculated based upon coverage and indemnity specified by the insurant, and an additional premium estimated based upon driving behavior submitted by the insurant are added and collected as a provisional premium. Driving behavior points are counted each time when actual driving behavior of the insurant deviates from criteria determined based upon the driving behavior. Safe driving points are counted each time when the actual driving behavior deviates from safe driving criteria submitted to the insurant in advance. The driving behavior points and the safe driving points are combined into demerit points, to calculate an actual additional premium corresponding to the demerit points, and a difference between the estimated additional premium and the actual additional premium is balanced upon expiration of the automobile insurance.

  • Publication number: 20020075527
    Abstract: It is an object of this invention to provide highly reliable image read operation by detecting the positions of white and black streaks that can occur in flow scanning and prevent the occurrence of such streaks. To achieve this object, in copy operation, for example, the continuity and position of image data read by a CCD to detect the data as abnormal pixels, thereby outputting an image without any streak. In facsimile transmission, the continuity, position, and linewidth of image data are detected to detect the data as abnormal pixels, thereby transmitting an image without any streaks.

  • Publication number: 20020048658
    Abstract: A recording sheet is provided, which difficultly undergoes handing of printed images formed thereon and which can permit to print with a pigment ink. In the recording sheet of the invention, an ink-permeable layer contains a filler and a surfactant of 9.0 or less in HLB value and surface of the filler particles is in a state of being covered with lipophilic groups of the surfactant, and thus an ink applied to the surface of the ink-permeable layer does not spread on the surface of the ink-permeable layer but is absorbed into the ink-permeable layer and, in the ink-permeable layer, the ink does not diffuse in the surface direction but migrates straight in the depth direction. Further, addition of a cation group-containing compound as a fixing agent to the ink-receiving layer of the recording sheet serves to improve fixing properties of the colorant in the ink-receiving layer, thus no banding occurring within the ink receiving layer as well.

  • Patent number: 6366100
    Abstract: An apparatus for testing a circuit board has a holder for holding the circuit board, a detector for detecting the electrical characteristics of the circuit board, and a controller for controlling laser plasma switches. The detector has a path forming unit positioned away from the circuit board by a predetermined gap. The path forming unit forms a first conductive path between a position corresponding to a first test pad on a trace of the circuit board and a first power source, as well as a second conductive path between a position corresponding to a second test pad on another trace of the circuit board and a second power source. The controller emits a laser beam to a first space between the first test pad and the first conductive path and another laser beam toward a second space between the second test pad and the second conductive path, to make the first and second spaces conductive.
