Patent number: 11926227Abstract: In a moving-object power supply system, a control unit selects, as a power transmission segment, one of segments included in at least one power transmission section. The control unit supplies, through a power supply circuit, power to the power transmission segment to thereby generate a magnetic field through a power transmission coil of the power transmission segment. The control unit determines, based on an ascertained first electrical characteristic of the power transmission segment and an ascertained second electrical characteristic of at least one power non-transmission segment, whether there is a malfunction in each of the power transmission segment and the at least one power non-transmission segment.Type: GrantFiled: November 17, 2021Date of Patent: March 12, 2024Assignee: DENSO CORPORATIONInventors: Kouji Mazaki, Nobuhisa Yamaguchi, Eisuke Takahashi, Mitsuru Shibanuma, Shinpei Takita, Masaya Takahashi, Hayato Sumiya, Masaki Kanesaki, Takuya Kiguchi, Kazuhiro Uda, Yuusei Nakayashiki

Patent number: 11440823Abstract: An object of the present invention is to provide a method for producing PHA, which is capable of suppressing the cost of overall production equipment including a waste water treatment process in production of PHA using microorganisms. Provided is a method including: a production step of purifying or molding polyhydroxyalkanoic acid biosynthesized in bacterial cells of a microorganism; a discharge step of discharging waste water containing nitrogen-containing impurities from the production step; and a nitrogen removal step of biologically treating the waste water to remove the nitrogen-containing impurities from the waste water. In the method, the residual ratio of the polyhydroxyalkanoic acid in the production step is 99% by weight or less, and the waste water that is biologically treated in the nitrogen removal step contains the polyhydroxyalkanoic acid in addition to the nitrogen-containing impurities.Type: GrantFiled: June 12, 2017Date of Patent: September 13, 2022Assignee: KANEKA CORPORATIONInventor: Masaki Takita

Publication number: 20200095147Abstract: Disclosed herein is a method for removing nitrogen from water, which makes it possible to omit equipment for controlling the supply of a carbon source (hydrogen donor), equipment for post-processing a carbon source (hydrogen donor), and circulation equipment and to prevent an increase in the size of a system. The method includes adding a solid material containing a biodegradable resin as a hydrogen donor to one water system in which bacteria cells having an ability to decompose a biodegradable resin, bacteria cells having nitrification capabilities, and bacteria cells having denitrification capabilities live together to allow a nitrification reaction and a denitrification reaction coexist in the water system. Also disclosed herein is a nitrification-reaction promoting agent for water treatment including 20 wt % or more of a biodegradable resin and having a specific gravity of more than 1 g/cm3.Type: ApplicationFiled: November 29, 2019Publication date: March 26, 2020Applicant: KANEKA CORPORATIONInventor: Masaki TAKITA
