摘要： A vacuum pump has a housing accommodating a rotary shaft and a gas transferring assembly driven by the rotary shaft. The housing has an exhaust passage for exhausting gas outside the housing. The gas transferring assembly creates a vacuum. A lip seal for shaft seal is disposed between a pump chamber communicating with the exhaust passage and a region in which oil exists so as to slide relative to a circumferential surface of the rotary shaft. The lip seal has a back pressure surface in a back pressure region facing the pump chamber and a pressure surface facing the region in which the oil exists. A communicating passage in the housing intercommunicates the back pressure region and the exhaust passage for applying at least substantially the pressure in the exhaust passage to the back pressure surface.

摘要： A post-processing liquid application device includes an ejecting head that ejects a post-processing liquid in a specific ejection pattern on a recording medium after ink has been attached thereto to form a character and/or an image based on image information, and a control unit that selects the specific ejection pattern based on a coverage rate calculated from the image information. When the coverage rate is low, the control unit selects a first ejection pattern for ejecting the post-processing liquid on a printed portion of a print region of the recording medium or ejecting the post-processing liquid on the printed portion and a surrounding portion thereof. When the coverage rate is high, the control unit selects a second ejection pattern for ejecting the post-processing liquid over the entire surface of the print region of the recording medium.
