  • Publication number: 20160361565
    Abstract: A radiotherapy spacer is disclosed that has both flexibility for allowing it to gently cover the organs of various shapes along their surfaces and pressure resistance for preventing itself from being crushed under the pressure between organs and thus enabling it to retain its own shape and continuously ensure the therapeutic space. The spacer comprises a fiber assembly formed of entangled biocompatible fibers, which may be bioabsorbable, such as nonwoven fabric, and is characterized in that the density of the fiber assembly is 0.05 g/cm3 to 0.2 g/cm3.

  • Patent number: 9494575
    Abstract: Provided are a method and means permitting the simultaneous measurement of the reactive properties of more than 10,000 of antigen-stimulated lymphocytes being held on a chip. A microwell array comprises multiple wells capturing single cells and a coating layer on a principal surface around the wells containing a substance capable of binding to a substance produced by the cells in the wells. A method for screening a target cell comprises: causing specimen cells and a cell culture broth to be contained in the wells of the microwell array; culturing the cells in a state permitting the diffusion of substances from the wells into the coating layer; feeding a label substance binding specifically to a substance produced by a target cell onto the coating layer; and detecting the substance produced by the target cell by the label substance binding around the well to specify the target cell.

  • Patent number: 9278543
    Abstract: A first ink tank, and a second ink tank including a first chamber having an ink inlet port and a second chamber having a sensing unit are provided. The ink inlet port is provided at a position so that a volume of the second ink tank above a second height does not become smaller than an amount of ink volume change in the second chamber when the ink volume is changed from a first height which is a height of the ink surface when a minimum volume of ink is in the second ink tank under normal usage to a second height which is a height of the ink inlet port.
