Publication number: 20240074490Abstract: The present invention addresses the problem of providing: a filter in which a liquid having phenol filtration capability is prevented from leaking out even after prolonged storage; and a flavor inhalation article equipped with said filter. The problem is solved by a filter that is for a flavor inhalation article, and that has a filtering medium including a biodegradable material, and a paper roll wound around the filtering medium. The filtering medium contains a liquid having a phenol filtration capability. A surface of the roll paper where a contact is made with the filtering medium is made of a layer exhibiting liquid-repellent properties with respect to said liquid.Type: ApplicationFiled: October 30, 2023Publication date: March 7, 2024Applicant: JAPAN TOBACCO INC.Inventors: Michihiro INAGAKI, Hiroyuki KUBOTA, Kuanhsuan LIN, Ryota Matsuba, Toru SAKURAI, Takeo TSUTSUMI, Tsukasa MANO, Pranav KULKARNI, Diego DA SILVA ROSA

Patent number: 8366846Abstract: Disclosed is an Al—Mg—Si aluminum alloy sheet that can prevent ridging marks during press forming and has good reproducibility even with stricter fabricating conditions. In an Al—Mg—Si aluminum alloy sheet of a specific composition, hot rolling is performed on the basis of a set relationship between the rolling start temperature Ts and the rolling finish temperature Tf° C., whereby the relationship of the cube orientation distribution profile in the horizontal direction of the sheet with the cube orientation alone or another crystal orientation distribution profile at various locations in the depth direction of the sheet is made more uniform, suppressing the appearance of ridging marks that develop during sheet press forming.Type: GrantFiled: March 26, 2009Date of Patent: February 5, 2013Assignee: Kobe Steel, Ltd.Inventors: Yasuo Takaki, Takeo Sakurai, Kwangjin Lee

Patent number: 7487655Abstract: A metal mold is disposed adjacent to the outer circumference of a base ring, and has a molding face in the inner circumference and a plurality of grooves for forming beads on the molding face along the circumferential direction. A coil for electromagnetic forming is disposed adjacent to the inner circumference of the base ring. When a momentary large current is applied to the coil in this arrangement, the diameter of the base ring is expanded by pressing the base ring toward the molding face of the metal mold such that the base ring is molded into a shape corresponding to the molding face by electromagnetic forming. Improvements such as a metal mold capable of degassing, a separable metal mold, roll-correcting after electromagnetic forming, application of momentary large current over several times, a metal mold with a cutting blade, use of a base ring with a large number of holes, and a metal mold with positioning means are then added.Type: GrantFiled: September 26, 2003Date of Patent: February 10, 2009Assignee: Kobe Steel, LtdInventors: Yoshihaya Imamura, Noritaka Eguchi, Takeo Sakurai, Hiroshi Tanimoto
