  • Publication number: 20120172830
    Abstract: A mixing apparatus for mixing a first component and a second component comprises: a first vessel which has a negative internal pressure and houses the first component; a second vessel which houses the second component; and a double-ended needle which allows communication between the first vessel and the second vessel when a first stopper element and a second stopper element have been pierced through by the needle. Penetration-resistance increasing parts which have a greater penetration resistance with respect to the first stopper element and the second stopper element than tip end tubes are respectively provided on a first puncture needle and a second puncture needle of the double-ended needle at positions further towards the base end than the tip end tubes. The axial heights of the edge faces of the tip end tubes are both less than the thicknesses of the first stopper element and of the second stopper element.

  • Patent number: 8120687
    Abstract: A signal reading method successively outputs a read signal by scanning a voltage value of an integrating capacitor in an image sensor in which a plurality of sensor parts are arranged in a two-dimensional array made up of rows and columns and each sensor part includes the integrating capacitor accumulating a charge obtained by integrating a photocurrent output from a sensor. A first integration of the photocurrent using the integrating capacitor and a first sampling and holding using a sample and hold capacitor are performed in a first time interval, during a time of one frame made up of the first through third time intervals. A second integration of the photocurrent using the integrating capacitor is performed in the second time interval, and processes in the first and second time intervals are performed in common with respect to all of the sensor parts simultaneously. A vertical scan is started by selecting the row in an order starting from a first row.
