  • Publication number: 20210080933
    Abstract: An image display device displays an image such that a pair of reference symmetric structure portions, e.g. a pair of guide pins, are included in a captured image displayed on a display section, the pair of reference symmetric structure portions being located symmetrically with respect to a second virtual plane which extends in the opening direction and the vertical direction and includes a virtual center line of the molding apparatus which extends in the opening direction. A teaching execution section is used to determine the lateral position of an approach frame in the take-out operation by changing the position of the approach frame such that the center of an imaging range is located at a middle position between the pair of reference symmetric structure portions included in the captured image.

  • Publication number: 20210079354
    Abstract: Provided is a method for efficiently and stably separating cells having a high biological activity from a biological tissue, by using a degrading-enzyme composition, which is prepared by adding an enzyme for degrading a major protein of the biological tissue in an amount determined depending on the composition of the major protein to a predetermined amount of a neutral protease and/or a protease derived from Clostridium sp. According to this method, the type and amount of protein-degrading enzyme to be used for isolating cells can be determined from the composition of a major protein of the biological tissue. Thus, cells having a high biological activity can be efficiently separated while reducing the amount of protein-degrading enzyme to be used.
