Patent number: 10024883Abstract: A block has a planar portion abutting a back side of a contact region of a flexible substrate, and a recess that is concave with respect to the planar portion. An electronic component mounted on the flexible substrate is located within the recess. When viewed from a direction perpendicular to the planar portion, the recess is located at a position near a power supply bump, except at a position overlapping the power supply bump, or the recess is filled with a filler. The planar portion of the block abuts only the back side of the power supply bump.Type: GrantFiled: March 23, 2016Date of Patent: July 17, 2018Assignees: Yokowo Co., Ltd., Murata Manufacturing Co., Ltd.Inventors: Takahiro Nagata, Takeshi Todoroki, Takahiro Nakamura, Yoshinori Ishikawa, Takayuki Kawano, Kazuhisa Honma

Patent number: 8723540Abstract: A contact probe includes: a first and second plungers, one of the first and second plungers being connected to an object to be inspected, the other being connected to an inspecting board; and a spring urging the first and second plungers so as to be separated from each other. The first plunger includes a distal end side columnar part and a flange part. The flange part includes a first portion that has a first length from a center point, which is, greater than a radius of the distal end side columnar part, in a first direction perpendicular to an axial direction, and includes a second portion that has a second length from the center point, which is smaller than the radius of the distal end side columnar part, in a second direction perpendicular to the axial direction and different from the first direction.Type: GrantFiled: January 17, 2012Date of Patent: May 13, 2014Assignee: Yokowo Co., Ltd.Inventors: Tsugio Yamamoto, Takeshi Todoroki

Process for induction culture of cytotoxic T lymphocytes having killing activity against tumor cells
Patent number: 5874307Abstract: A process for an induction culture of a cytotoxic T lymphocyte having cell killing activities against a tumor cell which comprises the step of coculturing a tumor tissue containing said tumor cell and a lymphocyte of autologous peripheral blood obtained from a subject from which the tumor tissue is derived. The process is convenient since no separation and pure culture of tumor cells is required. The resulting cytotoxic T lymphocyte cells are useful for clinical treatments of tumors, e.g. adoptive immunotherapies.Type: GrantFiled: June 20, 1995Date of Patent: February 23, 1999Assignee: The Institute of Physical and Chemical ResearchInventors: Tadao Ohno, Shu Qin Liu, Takeshi Todoroki -
Patent number: 5401742Abstract: Methotrexate, which is a known anticancer agent, can be converted into a polymeric conjugate with a pyran copolymer, which in itself has a certain anticancer effect, by a method in which an alkylene diamine is reacted with the carboxyl group of the methotrexate molecule to give an amidation product having a free amino group in a molecule, which is then reacted with the carboxyl group of the pyran copolymer, of which at least 10% of the repeating units have been modified with the methotrexate residue. The polymeric conjugate has sustained releasability of the methotrexate compound in blood serum so that an excellent therapeutic effect can be obtained by the administration thereof against cancers with little problems due to the side effects caused by an unduly high concentration of the drug in blood unavoidable when methotrexate as such is administrated.Type: GrantFiled: March 18, 1994Date of Patent: March 28, 1995Assignee: Japan, as represented by Director General of Agency of Industrial Science and TechnologyInventors: Takashi Hirano, Takeshi Todoroki, Shinichi Ohashi, Tomokuni Kokubu, Hideaki Tanaka

Patent number: 5252673Abstract: A macromolecular mitomycin derivative excellent in antitumor ability is produced by causing a specific divinyl ether-maleic anhydride copolymer to react with a specific aminocarboxylic acid and causing mitomycin C to react on the resultant reaction product. The derivative is optionally converted into a pharmacologically acceptable salt.Type: GrantFiled: March 12, 1992Date of Patent: October 12, 1993Assignees: Agency of Industrial Science & Technology, Ministry of International Trade & IndustryInventors: Takashi Hirano, Takeshi Todoroki, Shinichi Ohashi
