Publication number: 20240114225Abstract: An inspection apparatus of an embodiment includes a rotor image-pickup unit for picking up an image of a rotor using a rotor image-pickup device in the air gap between the rotor and a stator. The rotor image-pickup device includes: a carriage casing; a camera; an image-pickup position changing part; and an image-pickup direction changing part. The camera is installed in the carriage casing, and picks up an image of a ventilation hole of the rotor in the air gap. The image-pickup position changing part is installed in the carriage casing, and changes an image-pickup position of the camera by moving the carriage casing in a circumferential direction of the rotor in the air gap. The image-pickup direction changing part is installed in the carriage casing, and changes an image-pickup direction of the camera to an inclined angle to a radial direction of the rotor in the air gap.Type: ApplicationFiled: July 24, 2023Publication date: April 4, 2024Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATIONInventors: Mitsunori YUMINAMOCHI, Akihiro MATSUZAKI, Masaoki SAITO, Hitoshi KATAYAMA, Fumio SATO, Dai NOZAKI

Patent number: 9821618Abstract: A suspension system for a traveling vehicle body is disclosed. The system includes a suspension reference position varying mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism (100), and a controller (35) configured to calculate an intermediate value from a maximal value corresponding to the maximal position of the suspension stroke and a minimal value corresponding to the minimal position of the suspension stroke, and to control the suspension reference position varying mechanism such that, when the calculated intermediate values deviates from a set target range, the intermediate value is displaced toward the target range. The controller (35) increases a control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is low, and reduces the control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is high.Type: GrantFiled: April 13, 2015Date of Patent: November 21, 2017Assignee: Kubota CorporationInventors: Kenichi Iwami, Shigeki Hayashi, Akihiro Matsuzaki, Toshimitsu Yazaki, Atsushi Hayashi, Kazuma Ishihara

Patent number: 9694679Abstract: A drive control system for a work vehicle is provided with a power transmission device that drives front wheels and rear wheels, a request determination unit, and a drive mode control unit. The power transmission device has a drive mode switching mechanism that performs drive mode switching between a four-wheel drive mode in which drive power is transmitted to front wheels and rear wheels and a two-wheel drive mode in which drive power is transmitted to only the rear wheels. The request determination unit determines a necessity for an increase in drive power on a contact area of the work vehicle, and outputs an increase request based on the determination result. The drive mode control unit outputs a drive mode switching request for switching to the four-wheel drive mode to the drive mode switching mechanism, in response to output of the increase request.Type: GrantFiled: July 10, 2015Date of Patent: July 4, 2017Assignee: Kubota CorporationInventors: Akihiro Matsuzaki, Satoshi Yoshikawa, Michita Kono
