Patent number: 11794970Abstract: A packaging body constituted by a sheet that includes a gas barrier laminate and a sealant; and contents that are accommodated in the packaging body and that contain a sulfur-containing amino acid. The gas barrier laminate comprises: a resin substrate; a first layer containing an inorganic oxide; a second layer containing a carboxylic acid polymer; and a third layer containing a polyvalent metal compound and a resin. The resin substrate, the first layer, the second layer, and the third layer are layered in this order from the outside to the inside of the packaging body. The thickness of the third layer is 0.1 ?m or more. The sulfur content of the second layer is 1.0 atm % or less.Type: GrantFiled: July 16, 2021Date of Patent: October 24, 2023Assignee: TOPPAN PRINTING CO., LTD.Inventors: Kengo Okamura, Miki Fukugami

Patent number: 6508343Abstract: A vibration damper little depending on temperature, capable of damping plural resonance vibrations over a wide frequency region as well as damping a specific frequency vibration is provided. The vibration damper comprises a housing formed of a rigid material, having an internal space and fixed to a vibration transmitting member, an elastic body inserted in the internal space not bonded thereto with a gap in a direction of vibration of the housing, and a weight integrally supported by the elastic body so as not to touch the housing. The elastic body and the weight form a dynamic damper.Type: GrantFiled: January 10, 2001Date of Patent: January 21, 2003Assignees: Honda Giken Kogyo Kabushiki Kaisha, Tokai Rubber Industries, Ltd.Inventors: Kazuhito Misaji, Kengo Okamura, Yuji Kuruhara, Keiichi Sunami, Tsuyoshi Yamashita, Akihiro Maejima, Yoshihiro Noguchi, Toru Nirei, Rentaro Kato, Koichi Hasegawa
