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

Publication number: 20220020457Abstract: To specify, collect, and manage data that matches a usage purpose of a user with high efficiency among enormous medical data. In a case where prescribed medical data is data worthy of evaluation for a user who manipulates a user terminal, a communication unit receives an evaluation result. A database generation unit selectively reads the medical data the evaluation result of which has been received by the communication unit among the medical data accumulated in a medical information storage, and stores the medical data in the storage unit. This processing is repeated every time when an evaluation result is received to generate a database.Type: ApplicationFiled: April 28, 2021Publication date: January 20, 2022Inventors: Xinxin XU, Maihefureti AINIWAER, Takashi SHIRAHATA, Kouji YAMAGUCHI

Patent number: 10274219Abstract: When a controller determines that a leakage of refrigerant occurs, the controller executes a control of rotating an air-sending fan at high rotation speed. After the control, the controller executes a control of stopping rotation of the air-sending fan or reducing a rotation speed of the air-sending fan in accordance with a result of detection by a first refrigerant sensor provided in a lower portion of a heat exchanger chamber. Thus, the air-sending fan is prevented from continuing the rotation at high rotation speed. Therefore, an indoor unit for an air-conditioning apparatus is excellent in safety and is capable of avoiding feeling of discomfort of a user due to the high-speed rotation of the air-sending fan.Type: GrantFiled: March 25, 2016Date of Patent: April 30, 2019Assignee: Mitsubishi Electric CorporationInventors: Hiroaki Makino, Kouji Yamaguchi, Tetsuya Tazawa
