  • Patent number: 7366626
    Abstract: A calibration method in which secular change in sensor output values obtained at calibration times is estimated and the next calibration date can be determined at an appropriate interval and a zirconia-type oxygen analyzer using the above calibration method is achieved. The present invention is characterized by the fact that, in a calibration method in which a standard sample having a known value is measured and the output value of a measuring instrument corresponding to a sensor output value at the time of measurement is calibrated, the sensor output value obtained in implemented calibrating operations is stored in succession as the data for calibration history and the state of secular change in said sensor output value is estimated based on the stored past data for calibration history to determine the next calibration date.

  • Publication number: 20070280730
    Abstract: A photosensitive unit is described. The photosensitive unit may include a developer cartridge including a developing agent carrier and a casing, a photosensitive member, and a side wall. The casing is provided with a pivoting member including a pressuring portion applied with an external pressing force and a fitting projection fitted to the side wall. The pivoting member is configured to be pivoted along a pressing direction for pressing the developing agent carrier toward the photosensitive member when a pressing force is applied to the pressuring portion, or along a pressure releasing direction opposite to the pressing direction. The side wall is formed with a fit portion to which the fitting projection is loosely fitted so that a movement of the fitting projection along a pivoting direction of the pivoting member is allowed.
