  • Patent number: 11905348
    Abstract: An object of the present invention is to provide a novel ethylene/?-olefin/non-conjugated polyene copolymer containing a certain non-conjugated polyene such as VNB as a copolymerization component, having a low long-chain branching content, excellent in cure characteristics in the case of crosslinking by using peroxide, and having good processability. The ethylene/?-olefin/non-conjugated polyene copolymer according to the present invention has constitutional units derived from ethylene (A), an ?-olefin (B) having 3 to 20 carbon atoms, and a non-conjugated polyene (C) having a total of two or more partial structures selected from the group consisting of the following general formulas (I) and (II) in a molecule, and satisfies certain requirements.

  • Patent number: 10864717
    Abstract: According to one embodiment, a tablet printing apparatus includes: a first rotator having an inner space; a duct configured to communicate with the inner space of the first rotator; a suction pipe configured to suck inside the duct; a second rotator arranged to face the first rotator across the duct; a conveyor belt wrapped around the first rotator and the second rotator; and a print head that performs printing on a tablet held on the conveyor belt. The conveyor belt includes a plurality of suction holes which communicate with the inner space of the first rotator and that of the duct, and are arranged in the rotation direction of the first rotator. The first rotator and the duct constitutes a suction chamber that applies a suction force to those of the suction holes of the conveyor belt located around the outer periphery of the first rotator and the duct.
