  • Patent number: 9375955
    Abstract: A printing apparatus includes a printing unit, a first and second conveying units conveying a printing medium, a driving unit driving the conveying units and a control unit controlling the driving unit. A load mutually acting on the conveying units through the medium in a conveyance state by the conveying units is recursively calculated for each predetermined conveyance unit while setting the initial value to 0. The driving unit is controlled based on the calculation result at the time of the transition to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state of the medium from the conveyance state by the conveying units to a conveyance state only by the second conveying unit.

  • Patent number: 9327527
    Abstract: A printing apparatus includes a printing unit, first and second conveying units conveying a printing medium, a driving unit driving the first and second conveying units, and a control unit controlling the driving unit. The conveyance state of the printing medium makes transition from a first conveyance state in which the printing medium is conveyed only by the first conveying unit to a second conveyance state in which the printing medium is conveyed by both the first and second conveying units. The control unit controls the driving unit based on a fluctuation in a load that mutually acts between the first and second conveying units through the printing medium to suppress a fluctuation in a conveyance amount at the time of the transition of the conveyance state from the first conveyance state to the second conveyance state.

  • Patent number: 8926054
    Abstract: Based on a conveyance amount in a second conveyance state where a sheet is conveyed by both a first conveyance unit and a second conveyance unit being a conveyance amount obtained by subjecting a conveyance amount in a first conveyance state where the sheet is conveyed only by the first conveyance unit and a conveyance amount in a third conveyance state where the sheet is conveyed only by the second conveyance unit to weighted average with difficulty of slipping of the first or second conveyance unit to the sheet as a weighting coefficient, a remaining conveyance amount is calculated from any two conveyance amounts from among conveyance amounts of the first, the second and the third conveyance states, and a correction value for conveyance is set from the calculated conveyance amount.

  • Patent number: 7473777
    Abstract: This invention relates to a method for the production of a halogen-containing phthalocyaline compound by the cyclization of phthalonitrile compounds either singly or in combination with a metal compound, characterized in effecting the cyclization in an organic compound having a hydroxyl group and/or a carboxylic acid in an amount in the range of 0.01-10 mass parts per one mass part of the phthalonitrile compounds while continuing the introduction of an inert gas. This method, by using a solvent capable of serving as a specific oxygen source destined to participate in the reaction of complexing a metal compound introduced into a phthalocyanine dye, permits the production of a phthalocyanine compound inexpensively in a high yield.

  • Patent number: 7239982
    Abstract: The present invention suppresses charges incurred by data communications. A controller transmits data values acquired by sensors to a data center at predetermined intervals. When a predetermined interval has elapsed, a data value to be transmitted is compared with the previously transmitted data value, and in the absence of a change that is equal to or more than a predetermined variation amount, this data value is not transmitted. When such a state in which data values are not transmitted continues for a predetermined interval or more, the data value is transmitted irrespective of the data value variation amount. Further, when the data value has changed abruptly, the data value is transmitted even if the predetermined interval has not yet elapsed. The present invention can be applied to a controller that transmits data values acquired by sensors to a data center for collecting these data values.

  • Publication number: 20040249599
    Abstract: The present invention relates to an information processing system which allows data acquired by sensors to be used in a simple manner. Sensors 12-1 to 12-N for measuring remaining amounts are provided respectively at tanks 11-1 to 12-N. Data relating to the remaining amounts of the tanks 11-1 to 12-N as measured by the sensors 12-1 to 12-N is transmitted by a controller 13 in a unified fashion to another device that is connected via a network. The other device predicts the date and time at which the remaining amount in a tank 11 will become zero, on the basis of the data thus received. Replenishment of the material to the tank 11 is carried out on the basis of this prediction. The prediction is calculated on the basis of the remaining amount in the tank 11, and the time period required for this remaining amount to be reached. The present invention is applicable to an information processing system in which sensors at a remote location are managed and information from those sensors is processed and used.
