Publication number: 20240141582Abstract: An oil-resistant agent containing a modified natural product which is a bio-based compound having at least one carboxyl group and in which a hydroxyl group of a carboxyl group is substituted with an R group, or a carboxyl group is substituted with an Ra group. R group: —X—R1 or —X-D-X?—R1. Ra group: wherein X is a direct bond, —O—, —NR11—, or —S—, and R1 is a hydrocarbon group having 1-40 carbon atoms, or a polysiloxane, D is an alkylene group having 1-10 carbon atoms, X? is —C(?O)—O—, —O—(?O)—, —C(?O)—NR12—, or —NR12—C(?O)— (where, R11 and R12 are each hydrogen or an alkyl group having 1-40 carbon atoms). Also disclosed is a textile product, an oil-resistant paper, a food packaging material or a food container each including the oil-resistant agent, as well as a method of treating paper with the oil-resistant agent.Type: ApplicationFiled: December 14, 2023Publication date: May 2, 2024Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Akane MATSUMOTO, Ryo AKUTA, Yuko SHIOTANI, Mayumi IIDA, Marina AIHARA, Yukinori TOGO, Tatsunori SAKAMAKI, Masahiro HIGASHI, Yosuke KISHIKAWA

Publication number: 20240084123Abstract: An oil-resistant agent including a polymer (A) in which a polymer (a1) having at least one selected from a hydroxyl group and an amino group is modified with a monovalent aliphatic hydrocarbon group having 7 to 40 carbon atoms (a2). A total amount of vinyl alcohol units and vinylamine units in all repeating units of the polymer (a1) is 40 mol % or more. Further, a ratio of modification of the polymer (A) with the aliphatic hydrocarbon group (a2) is 25 to 100 mol % relative to a total amount of hydroxyl groups and amino groups of the polymer (a1). Also disclosed is a paper product treated with the oil-resistant agent, and an oil-resistant agent wherein the polymer (a1) and the aliphatic hydrocarbon group (a2) are bonded through an ester bond.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Tatsunori SAKAMAKI, Ryo AKUTA, Akane MATSUMOTO, Marina AIHARA, Masahiro HIGASHI, Hirokazu AOYAMA, Yosuke KISHIKAWA

Patent number: 11092651Abstract: A high-frequency characteristic inspection apparatus includes a pair of high-frequency probes that inspect an electrical characteristic of a plane circuit including a signal region and a ground region formed apart from each other by an S parameter obtained by pushing a tip against a surface of the plane circuit and discharging a high frequency and a measurement apparatus. The high-frequency probe includes a ground terminal that is in contact with the ground region at its tip and a signal terminal that is in contact with the signal region simultaneously with the ground terminal at its tip. The pair of high-frequency probes are configured to contact with a surface of the plane circuit at the same time while facing each other at a certain interval.Type: GrantFiled: April 12, 2017Date of Patent: August 17, 2021Assignee: National Institute of Advanced Industrial Science and TechnologyInventor: Ryo Sakamaki

Patent number: 10944146Abstract: The invention provides a dielectric waveguide for transmitting millimeter waves or sub-millimeter waves. The dielectric waveguide is easily processed and connected even when having a small diameter, and can provide a connection structure exhibiting low transmission and return losses of high frequency signals. The dielectric waveguide includes a dielectric waveguide body and a dielectric waveguide end having a lower permittivity than the dielectric waveguide body. The dielectric waveguide body and the dielectric waveguide end are seamlessly and monolithically formed from the same material.Type: GrantFiled: September 29, 2017Date of Patent: March 9, 2021Assignees: DAIKIN INDUSTRIES, LTD., NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGYInventors: Hiroyuki Yoshimoto, Dai Fukami, Taku Yamanaka, Masahiro Horibe, Yuto Kato, Ryo Sakamaki
