  • Patent number: 10717287
    Abstract: An ink refill container 63 includes a container main body 64 including an ink storage chamber 76, an ink outlet-forming portion 66 provided on an end portion of the container main body forming an ink outlet 65 that allows the ink to flow out from the ink storage chamber, and a valve 74 provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion 73 on an outer side of the ink outlet-forming portion. in which the positioning portion 73 is closer to the container main body than the valve 74 is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank 41-45 when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.

  • Patent number: 5936035
    Abstract: Collagen-based compositions useful in the attachment of tissues, or the attachment of tissues to synthetic implant materials, are disclosed. The compositions comprise collagen crosslinked using a multifunctionally activated synthetic hydrophilic polymer. A particularly preferred composition comprises fibrillar collagen, a fiber disassembly agent, and a multifunctionally activated synthetic hydrophilic polymer. Methods are disclosed for using the compositions to effect the attachment of a native tissue to the surface of another native tissue, a non-native tissue, or a synthetic implant. Also disclosed are methods of using the compositions to prevent the formation of surgical adhesions.

  • Patent number: 5200120
    Abstract: The optical disc of the present invention has a transparent substrate provided on the surface opposite to the surface of a metallic reflective film in contact with a recording layer, and reading of predetermined information is performed by permitting a laser beam to be incident from the transparent substrate side. That is, light is reflected on the surface on the opposite side to the surface of the metallic reflective film in contact with the recording layer, and by employment of such a mechanism, it becomes possible to enhance the reflectance in the metallic reflective film, and also the difference in surface reflectance between the concavity and the convexity is effectively corrected at the uneven pit portion with memorized information.
