Patent number: 11979104Abstract: A rotary electric machine control apparatus (1) suitably controls two inverters (10) connected to associated ends of open windings (8). The rotary electric machine control apparatus (1) performs target control involving: controlling a first one of the inverters (10), which is selected from a first inverter (11) and a second inverter (12), by rectangular wave control; and controlling a second one of the inverters (10) by special pulse width modulation control that is one type of pulse width modulation control. The special pulse width modulation control is a control method to produce a switching pattern (Su2+) that is based on a difference between a switching pattern resulting from the pulse width modulation control and a switching pattern (Su1+) resulting from the rectangular wave control when a target voltage is to be generated in the open windings (8).Type: GrantFiled: September 29, 2020Date of Patent: May 7, 2024Assignees: AISIN CORPORATION, NAGOYA INSTITUTE OF TECHNOLOGYInventors: Subrata Saha, Hiroki Iwai, Takashi Kosaka, Hiroaki Matsumori

Patent number: 11247740Abstract: A vehicle includes a fragile portion provided in an exhaust passage at a position frontward of a dashboard panel in a vehicle front-rear direction, and a thrusting portion. The fragile portion fractures more easily under a force from a front side of the vehicle than other portions of the exhaust passage. The thrusting portion is provided in one of the exhaust passage, at a position frontward of the dashboard panel and rearward of the fragile portion in the vehicle front-rear direction, and a framework member that is part of a frame structure of the vehicle and supports the dashboard panel. The thrusting portion protrudes from the one of the exhaust passage and the framework member toward the other one and facing the other one in the vehicle front-rear direction.Type: GrantFiled: August 12, 2019Date of Patent: February 15, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryosuke Nagata, Hiroaki Kosaka

Patent number: 9273050Abstract: Provided is a compound having at least one selected from the group consisting of cell growth promoting activity, angiogenesis promoting activity, lumen formation promoting activity, cell migration promoting activity, and neurocyte growth promoting activity, which is a chemically stable low-molecular-weight substance that has high absorbability and can be supplied stably at a low cost because of its low molecular weight. A cyclobutyl purine derivative, a tautomer or stereoisomer thereof, or a salt, solvate, or hydrate thereof according to the present invention is a cyclobutyl purine derivative represented by the following general formula (1), a tautomer or stereoisomer thereof, or a salt, solvate, or hydrate thereof.Type: GrantFiled: November 27, 2009Date of Patent: March 1, 2016Assignee: National University Corporation Kagawa UniversityInventors: Ikuko Tsukamoto, Ryoji Konishi, Masaaki Tokuda, Yasuo Kubota, Tokumi Maruyama, Hiroaki Kosaka, Junsuke Igarashi

Patent number: 8280602Abstract: An operation assist apparatus including: an assist controller that assists a driver of a vehicle in operating the vehicle before a stop point; and a watching action detector that detects a watching action of the driver for watching the stop point. The assist controller changes an assist manner in which to assist the vehicle operation by the driver in accordance with whether the watching action is detected by the watching action detector during deceleration of the vehicle. Thus configured, the operation assist apparatus can accurately determine whether the driver will stop the vehicle at the stop point and thus can perform the vehicle operation assist appropriately.Type: GrantFiled: August 1, 2007Date of Patent: October 2, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, National University Corporation Nara Institute of Science and TechnologyInventors: Masaaki Uechi, Kazuya Sasaki, Masumi Kobana, Hirokazu Nishitani, Hiroaki Kosaka

Publication number: 20060201806Abstract: It is an object of the present invention to provide a method for forming a thin-film layer on the outer surface of a sensor, by which a thin-film layer formed on the surface of a sensor used for measuring the concentration of elements contained in the measurement object such as a molten metal, slag, or gas, can be easily provided with a complex pattern shape of small thickness and a uniformly arranged pattern shape. The method is provided for forming a thin-film layer of a sensor composed of a solid electrolyte which is a molded body having an inner space, a reference substance filled in the inner space, a reference electrode connected to the reference substance and led out to the outside of the inner space, and a thin-film layer comprising a ceramic powder or a metal powder as the main component and formed on the outer surface of the solid electrolyte in such a manner that part of the outer surface is exposed. This thin-film layer is formed by printing.Type: ApplicationFiled: February 27, 2004Publication date: September 14, 2006Applicants: HERAEUS ELECTRO-NITE JAPAN, LTD., MIYAGAWA KASEI INDUSTRY CO., LTD.Inventors: Masanori Iwase, Kiyoshi Matsushita, Hideki Watanabe, Yukio Terauchi, Hiroaki Kosaka
