Patent number: 12103513Abstract: A vehicle controller controls a power train of a vehicle and is configured to switch control of the power train between first control and second control. The second control reduces operating noise of the power train by a greater degree than the first control. The vehicle controller is configured to based on sounds in a passenger compartment, perform mood determination in order to determine whether an occupant of the vehicle is in a state of high tolerance for the operating noise or in a state of low tolerance for the operating noise; control the power train through the first control when determining that the occupant is in the state of high tolerance through the mood determination; and control the power train through the second control when determining that the occupant is in the state of low tolerance through the mood determination.Type: GrantFiled: February 23, 2022Date of Patent: October 1, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keiji Kaita, Takahiko Hirasawa, Kentaro Otokubo, Hirotaka Omisha, Kimihiro Nakayama

Patent number: 12100571Abstract: An X-ray tube device capable of preventing a holder holding a bearing from suffering damage, and an X-ray CT apparatus including the X-ray tube device are provided. The X-ray tube device includes: a cathode that produces an electron beam; an anode that produces X rays upon irradiation with the electron beam; a rotating portion that supports and rotates the anode; bearings that are placed at a predetermined distance from each other in a direction of a rotation axis of the rotating portion, each of the bearings having an outer ring and an inner ring between which rolling elements are sandwiched; and a holder that holds the outer rings. The holder has an inner wall that is spaced from an edge of the outer ring.Type: GrantFiled: June 14, 2022Date of Patent: September 24, 2024Assignee: FUJIFILM CorporationInventors: Yutaro Tanabe, Kimihiro Nakayama, Ren Sonoda, Yoshitaka Seki

Publication number: 20240105415Abstract: A lightweight X-ray tube assembly and X-ray CT equipment having the same. The X-ray tube assembly includes an X-ray tube and a tube housing. The X-ray tube includes: a cathode for generating an electron beam; an anode for radiating X rays by collision of the electron beam; an envelope for holding the cathode and the anode in a vacuum atmosphere; and an X-ray window provided in the envelope to irradiate some of X rays radiated from the anode toward a test subject. The tube housing encapsulates the X-ray tube together with an insulating oil. The X-ray tube assembly further includes a protective member that is provided at least around the X-ray window on an outer wall of the envelope and shields the X rays.Type: ApplicationFiled: July 5, 2023Publication date: March 28, 2024Inventors: Kimihiro Nakayama, Yutaro Tanabe, Ren Sonoda

Patent number: 7253536Abstract: A water supply apparatus includes an apparatus body disposed in a flow passage for sucking water to an indoor facility and a power generation unit installed in the apparatus body. Further, the power generation unit further comprises a rotating shaft extended in a direction perpendicular to the water channel direction of the flow passage, and impeller installed on the rotating shaft and rotated by a water flow, a magnet rotated interlockingly with the impeller, and a coil arranged oppositely to the magnet, wherein the impeller forms blades in the radial outer direction and forms clearances allowing water to pass to the inside of the blades. Since the clearances are formed between the blades and the rotating shaft such a trouble that water flowing into the base ends of the blades obstructs the rotation of the impeller can be eliminated to increase a power generation amount by the power generation unit.Type: GrantFiled: March 29, 2004Date of Patent: August 7, 2007Assignee: Toto Ltd.Inventors: Hidefumi Fujimoto, Naoyuki Onodera, Kimihiro Nakayama, Makoto Hatakeyama, Kazuyuki Enomoto, Yukihiro Kudoh, Tatsuhiro Kuga, Satoshi Ishimaru
