  • Publication number: 20130294955
    Abstract: A fluid transporting apparatus includes a plurality of fingers arranged along a transporting direction in which fluid is transported by a tube having elasticity, the fingers reciprocatingly moving to compress or release the tube, and a driving section configured to move the plurality of fingers in a compressing direction. The fingers move in the compressing direction and crush the tube with ends of the fingers to transport the fluid on the inside of the tube in the transporting direction. The shape of the crushed tube is restored to fill the fluid in the inside of the tube. In a releasing action, in a state in which the ends of the fingers are in contact with the tube, movement of the fingers in a releasing direction is limited to a predetermined position.

  • Publication number: 20120148429
    Abstract: A fluid conveying device includes: a tube; a cam having protrusions; fingers arranged along the tube between the tube and the cam; a driving rotor which rotates the cam to sequentially push the fingers by the protrusions in a flowing direction of a fluid, repeatedly pressuring and opening of the tube, driving the cam; a detection unit which detects a rotating position of the cam; a control unit which calculates a cam rotation angle along a cumulative ejection volume, using a first approximation formula for an ejection area H where the cumulative ejection volume increases substantially in proportion to the rotation angle of the cam and a second approximation formula for a constant area J where the cumulative ejection volume little increases or decreases even if the cam rotates, driving the driving rotor until a rotating position of the cam corresponding to a designated cumulative ejection volume is reached.

  • Patent number: 7359110
    Abstract: An active matrix electrophoretic display is driven. In a reset period Tr a reset voltage is applied to each pixel electrode. Next, in a writing period an applied voltage is applied to each of said pixel electrode during a time period corresponding to a gradation value designated by an image data. Next, a common voltage is applied to each of said pixel electrode, so that electric charge accumulated in each capacitor is taken away and no electric field is applied to each dispersal system, thereby a displayed image is held.
