    Abstract: A degassing device removes air dissolved in a liquid under a pressure decreased atmosphere, and includes a liquid tank, a pressure decreasing device, a circulation flow pass, a circulation device, and a variable mechanism. The liquid tank stores the liquid. The pressure decreasing device decreases pressure in the liquid tank. The circulation flow pass communicates different positions of the liquid tank. The circulation device circulates the liquid through the circulation flow pass. The variable mechanism changes a height of an inlet port from the circulation flow pass to the liquid tank in accordance with a height of a liquid surface in the liquid tank.

    Abstract: An inkjet recording apparatus includes a recording head arranged so that a nozzle surface thereof is inclined, a conveyance unit, a cap, a suction portion, and a control portion. The cap includes a bottom surface and side walls provided to stand along four sides of the bottom surface. In detaching the cap from the nozzle surface, the control portion sequentially executes a first release operation in which, in a state where a lower positioned one of the side walls is in contact with the nozzle surface, others of the side walls are released from the nozzle surface, a wiping operation in which, while the lower positioned one of the side walls is kept in contact with the nozzle surface, the cap is moved upward along the nozzle surface, and a second release operation in which all the side walls of the cap are released from the nozzle surface.

    Abstract: A degassing device removes air dissolved in a liquid under a pressure decreased atmosphere, includes a liquid tank, a pressure decreasing device, a circulation flow pass, a circulation device, a dissolved gas amount measuring device, and a control device. The liquid tank stores the liquid. The pressure decreasing device decreases pressure in the liquid tank. The circulation flow pass communicates different positions of the liquid tank. The circulation device circulates the liquid through the circulation flow pass. The dissolved gas amount measuring device measures an amount of dissolved gas of the liquid in the liquid tank. The control device controls the circulation device in accordance with the amount of dissolved gas measured by the dissolved gas amount measuring device.

    Abstract: A fixing device includes a heated rotational body, a heating unit, a pressing rotational body, a pressing mechanism, a drive unit, a position recognition part, a rotational state determination part, a drive control part, and a pressing control part. The heated rotational body has a pattern. The position recognition part is configured to recognize a specific point contained in the pattern at a prescribed period. The rotational state determination part is configured to determine a variation in a rotational speed of the heated rotational body and a meandering state of the heated rotational body based on a position of the specific point recognized at the prescribed period. The drive control part is configured to control the drive unit based on the variation in the rotational speed. The pressing control part is configured to control the pressing mechanism based on the meandering state.
