  • Publication number: 20230183506
    Abstract: An image forming method includes: preparing a fabric to which an aggregating agent is attached; applying an aqueous ink containing a pigment, a first resin, and water onto the fabric to which the aggregating agent is attached; and applying a coating liquid containing a second resin and water onto the applied aqueous ink, wherein the second resin is aggregated by the aggregating agent, a content of the second resin in the coating liquid is smaller than a content of the first resin in the aqueous ink, and an amount of the coating liquid attached to the fabric is larger than an amount of the aqueous ink attached to the fabric.

  • Publication number: 20230065145
    Abstract: An inkjet recording device includes: an inkjet unit that ejects ink to a recording medium while scanning in a main scanning direction; a first treatment liquid ejection head that is arranged side by side with the inkjet unit in the main scanning direction, scans together with the inkjet unit, and ejects a first treatment liquid to the recording medium; and a second treatment liquid ejection head that is arranged side by side with the inkjet unit in the main scanning direction, scans together with the inkjet unit, and ejects a second treatment liquid different from the first treatment liquid to the recording medium, wherein at least one of the first treatment liquid ejection head and the second treatment liquid ejection head is arranged on both sides of the inkjet unit in the main scanning direction.

  • Patent number: 11155095
    Abstract: An inkjet recording apparatus includes an ink jetter; a transfer unit that has an intermediate transfer body and transfers ink on its transfer surface to a recording medium to record an image; a thickening device that thickens the ink landed on the transfer surface before transfer to the recording medium; a cleaner that removes residual ink remaining on the transfer surface; and a hardware processor. The cleaner has a first ink remover that removes the thickened residual ink in first ink removing operation in which an adhesive member brought into contact with the thickened ink is separated from the transfer surface. If the transfer surface has a region occupied by the thickened ink of a predetermined reference area or more, the hardware processor causes the first ink remover to perform the first ink removing operation.

  • Patent number: 8816615
    Abstract: In a drive device for a railway vehicle, in which regeneration braking force is increased by adding the output voltage of a voltage adjustment device to a DC power source voltage, operation of the current control device is started prior to the start of the power running operation or the regeneration operation of the inverter device, and the operation of the current control device is stopped later than the stopping of the power running operation or the regeneration operation of the inverter device. Thereby, the current control device is surely operated at least during the operation period of the inverter device, so that the output voltage of the voltage adjustment device is adjusted by the current control device, to thereby prevent the over-discharge of the energy storage device at the time of power running operation or the overcharge of the energy storage device at the time of regeneration operation.
