Publication number: 20230262341Abstract: A physical body inspection system includes a light source device, an image pickup device and a display. The light source device is configured to apply light in a predetermined wavelength band to a physical body, the physical body being an inspection object, the predetermined wavelength band being a wavelength band in wavelength bands constituting environment light at an inspection time-of-day, and the light in the predetermined wavelength band being low in intensity. The inspection time-of-day is a time of day when the physical body is inspected. The image pickup device is configured to pick up an image of the physical body. The display is configured to display the picked-up image of the physical body.Type: ApplicationFiled: February 9, 2023Publication date: August 17, 2023Applicant: TOYOTA PRODUCTION ENGINEERINGInventor: Haruki KABASHIMA

Patent number: 11518672Abstract: A fluid pressure feeding device includes: a follower plate that is inserted into a tank, that applies a pressing force to a fluid, and that has an opening for pumping up the fluid from an inside of the tank; a pump having a primer plate configured to exhibit reciprocating movement to pump up the fluid in the tank into a pump internal space; and a position control unit configured to control a position of the primer plate within a range of the reciprocating movement. An outer shape of the primer plate substantially matches a shape of the opening of the follower plate, and the position control unit is configured such that the primer plate is positioned in the opening of the follower plate when the follower plate is taken out from the tank.Type: GrantFiled: December 30, 2020Date of Patent: December 6, 2022Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, PYLES JAPAN Co., LTD., TOYOTA PRODUCTION ENGINEERINGInventors: Masahiro Tasaka, Kunimi Abiru, Shoji Suzuki, Takatoshi Urashi, Katsura Hara, Tomohiro Tokunaga, Naoki Yamaguchi

Patent number: 11325334Abstract: A load detection device includes a detector, a wireless transmitter, a power source, and a controller. The load detection device is provided in dies that includes a first die and a second die. The load detection device is installed on at least one of the first die and the second die and configured to detect whether the first die and the second die are in a closed state. The controller is configured to execute an electricity cutoff process of stopping electricity supply from the power source to the detector and the wireless transmitter when the closed state of the first die and the second die has continued for a predetermined time.Type: GrantFiled: November 13, 2019Date of Patent: May 10, 2022Assignee: TOYOTA PRODUCTION ENGINEERINGInventor: Yuki Ishida
