Patent number: 11919932Abstract: Disclosed are a novel therapeutic means effective and practical against cancer, and a novel substance useful as such a therapeutic means. Provided are novel peptides derived from a partial region of HMGN1, HMGN2, HMGN4 or HMGN5, and anti-cancer agents and anti-cancer effect enhancers containing the peptide as an active ingredient. The peptide of the present invention has an anti-tumor effect even independently, and exerts a remarkably excellent anti-tumor effect particularly when used in combination with an immune checkpoint regulator, or an anti-CD4 antibody or antigen-binding fragment thereof.Type: GrantFiled: January 3, 2023Date of Patent: March 5, 2024Assignees: THE UNIVERSITY OF TOKYO, ONO PHARMACEUTICAL CO., LTD., TOKYO UNIVERSITY OF SCIENCE FOUNDATIONInventors: Kouji Matsushima, Satoshi Ueha, Shungo Deshimaru, Chang-Yu Chen, Shoji Yokochi, Yoshiro Ishiwata, Shiro Shibayama

Patent number: 11092246Abstract: A gate valve comprising a plurality of first force-applying units built in a valve box; a second force-applying unit disposed between a first movable valve and a second movable valve; and a third force-applying unit. The first force-applying units are driven by incompressible fluid and have a function of applying a force to the first movable valve to be directed to the first opening portion in the flow passage direction and thereby causing the seal portion to be in close contact with a valve box inner surface located at the periphery of the first opening portion. The gate valve includes an incompressible-fluid driver that drives, the first force-applying units by incompressible fluid.Type: GrantFiled: February 5, 2019Date of Patent: August 17, 2021Assignee: ULVAC, INC.Inventors: Shinichi Wada, Hideaki Inoue, Kouji Shibayama, Takuya Wade, Harukuni Furuse, Jirou Endo, Mikiya Suzuki, Shinnosuke Tokuhira, Takaaki Terui

Patent number: 9273568Abstract: Provided is a coupling structure for vacuum exhaust devices each including a pump chamber and a casing that demarcates the pump chamber. The coupling structure includes a first end surface formed on a first side of the casing, and a second end surface formed on the second side of the casing, the second side being the opposite side of the first side. The casing of a first vacuum exhaust device and the casing of a second vacuum exhaust device among a plurality of vacuum exhaust devices are arranged to be directly superposed on each other such that the first end surface provided to the first vacuum exhaust device and the second end surface provided to the second vacuum exhaust device come into contact with each other. By fastening the first end surface and the second end surface, the first vacuum exhaust device and the second vacuum exhaust device are connected to each other such that gas can flow between the casing of the first vacuum exhaust device and the casing of the second vacuum exhaust device.Type: GrantFiled: November 16, 2011Date of Patent: March 1, 2016Assignee: ULVAC, INC.Inventors: Toshio Suzuki, Tomonari Tanaka, Kouji Shibayama, Masatomo Okamoto
