  • Patent number: 8969092
    Abstract: Provided is a gel particle measurement reagent effective in quickly measuring a time point of initiation of production of gel particles. A gel particle measurement reagent R is a gel particle measurement reagent to be used to be agitated continuously with a sample S containing a target substance St as a measuring object to turn the target substance St into gel particles, including: a reagent base material 1 that undergoes a gelation reaction with the target substance St; and a biologically inactive particle formation accelerating factor 2 that is added to the reagent base material, has solubility in the sample S and dissolves therein at a concentration of 0.002 to 1%, and accelerates production of gel particles G whose particle sizes are centered in a predetermined range.

  • Patent number: 8225375
    Abstract: The invention is to alleviate cumbersome operations of manager such as registration and deletion of authentication information. A card ID read from an IC card is transmitted to an IC card authentication server to obtain a first authentication result, and when the first authentication result indicates a successful authentication, the use of a composite apparatus is permitted. When the first authentication result indicates a failed authentication, an input user name is transmitted to a directory service server to obtain a second authentication result, and, when the second authentication result indicate a successful authentication, the card ID failing the authentication and the user name succeeding in the authentication are transmitted for requesting a registration to an IC card authentication server, which, receiving the request, registers the card ID and the user name in the registration request in combination in an authentication table.

  • Patent number: 7061648
    Abstract: Calibration associated with output density correction of a printer is effected by software calibration manipulated by the user and device calibration automatically performed by the printer, and, regarding these calibrations, high accurate calibration in which dither patterns for binarizing processing are matched to each other is effected. In a system in which either one of halftone patterns A, B, C and D as dither patterns can be used, regarding fewer number of patterns A and B, second calibration tables are created by correcting first calibration tables based on the software calibration by using correction data of engine characteristics based on the device calibration. Among the usable halftone patterns, the calibration table corresponding to the pattern A or B is selected in accordance with the set halftone pattern, and the output density correction by using the selected table.

  • Patent number: 6968499
    Abstract: Contents to be embedded in a page template or layouts can be dynamically changed without editing an HTML file or correcting a server program such as CGI. A page template is defined with a servlet that specifies a display area and a display attribute for controlling displays as parameters. When the Servlet is recognized at the web server side, a plurality of part beans that are stored by being related to display-area specifying information are specified. The information for linking image data for forming an object to be embedded in the display area and link-destination-URL information are set to the part beans as properties. Moreover, display-condition information such as schedule information or the like is related to the part beans.

  • Patent number: 6616262
    Abstract: A method of controlling an image processing condition comprises: a first step of inputting a first test image on a recording sheet, and performing first calibration that determines an image processing condition based on a density of the first test image; a second step of automatically forming a second test image, measuring a density thereof, and performing second calibration that determines the image processing condition based on the measured density, a third step of receiving the image processing condition, calibrating the received condition and an engine characteristic at first calibration time, and storing a calibrated result, and a fourth step of correcting, at the second calibration and the image processing condition storage, the stored condition based on the calibrated and stored engine characteristic and the measured engine characteristic. Thus, a printing characteristic can be stabilized as a user's load is reduced by combining plural calibrations.
