  • Publication number: 20220170913
    Abstract: A method for processing a blood sample is provided that can improve the recovery rate of deformable rare cells that would easily pass through a filter and small rare cells while reducing the filtration area of the filter, and that can recover the rare cells alive. In one aspect, the present disclosure relates to a method for separating or detecting rare cells in a blood sample using a filter including holes with a hole density of at least 200 holes/mm2 to 40000 holes/mm2, wherein the holes are in the form of an ellipse with a minor axis diameter of 3.0 ?m to 15 ?m and a major axis diameter of 1.1 times to 3 times as long as the minor axis diameter, or the holes have a shape that contains the ellipse and is in contact with the ellipse on at least two points including both ends of the major axis of the ellipse. The method includes separating or detecting rare cells by filtering the blood sample in a volume of 6 ?l/hole or less with respect to a hole of the filter.

  • Patent number: 10121606
    Abstract: An electrode for an energy storage device including a Zn layer or Zn alloy layer, a Ni layer, and a Sn layer or Sn alloy layer formed by plating on a connecting terminal part of a positive electrode composed of Al so that the resistance value at the contacting point is reduced and the voltage of the energy storage device can be effectively supplied without any drop. Accordingly, this electrode can be soldered to a Cu negative electrode, which is composed of metal that is different species from Al, through a Sn layer or a Sn alloy layer so that jointing strength of the Al positive electrode and the Cu negative electrode can be enhanced. The contacting area is increased in comparison with the conventional jointing by spot-welding or conventional fastening by a bolt so that the resistance value at the contacting point is reduced.

  • Patent number: 9368249
    Abstract: Zn layer 21 or Zn alloy layer, Ni layer 22, and Sn layer 23 or Sn alloy layer are formed on a connecting terminal part 10a of a positive electrode composed of Al by plating. Accordingly, this can solder Cu negative electrode, which is composed of metal that is different species from Al, through Sn layer 23 or Sn alloy layer so that jointing strength of the Al positive electrode and the Cu negative electrode can be enhanced. Further, since the contacting area is increased in comparison with the conventional jointing by the spot-welding or the conventional fastening by a bolt so that the resistance value at the contacting point is reduced, the voltage drop of the energy storage device by contact resistance can be reduced.
