  • Patent number: 11918759
    Abstract: A medical braided tube assembly includes a braided tube including a hollow cylindrical inner resin layer, a braided wire including braided strands and being provided over a periphery of the inner resin layer, and an outer resin layer provided to cover peripheries of the inner resin layer and the braided wire, and a connector provided at an end portion of the braided tube. The connector includes a tube housing section for accommodating the end portion of the braided tube. The braided tube accommodated in the tube housing section are adhesively fixed by an adhesive. The adhesive is provided to seal an entire periphery of the braided wire at an end face of the braided tube.

  • Patent number: 11458757
    Abstract: A lithographic printing plate precursor includes an image recording layer on a support, in which the lithographic printing plate precursor has projections which are discontinuously formed on a surface of an outermost layer on a side where the image recording layer is provided, and a melting point of each projection is in a range of 70° C. to 150° C. A method of producing a lithographic printing plate includes a step of image-wise exposing the lithographic printing plate precursor to form an exposed portion and an unexposed portion, and a step of supplying at least one of printing ink or dampening water to remove the unexposed portion.
