Publication number: 20240059534Abstract: A carrier body of a lift carrier includes: a pair of wheel support mechanisms that supports a first wheel of a vehicle to be transported; a frame-shaped structure connected to the wheel support mechanisms; and one or more lifting units that lift or lower the pair of wheel support mechanisms. The frame-shaped structure includes a frame portion and an upper plate and is open on a lower side of the carrier body. Each of the lifting units includes a wheel support and an air spring. The air spring is interposed between the wheel support and an upper plate. As the air spring expands, the wheel support is rotated about one end of the wheel support rotatably supported by the frame portion, and is deployed out of the frame-shaped structure.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshiki KITAJIMA, Norinao WATANABE, Yutaka NAKAMURA, Naoya KAJITA, Kenji NAKANO, Takafumi SANNOMIYA, Yasutada SHIMIZU, Kohei YASUDA

Publication number: 20220410789Abstract: A vehicle transporting device includes a bogie frame, a device main body, and an upright frame. The upright frame connects a tip portion of the bogie frame and the device main body. The bogie frame includes two frame members and at least two pipes, which are disposed parallel to a longitudinal direction of the bogie frame. The two frame members are disposed parallel to the at least two pipes at a position outside the at least two pipes in a width direction of the bogie frame. The at least two pipes include two pipes facing each other in the width direction. A reinforcing member extending in the width direction is provided at the tip portion of the bogie frame and between the two facing pipes. The two frame members, the reinforcing member, and the upright frame are connected to each other at the tip portion of the bogie frame.Type: ApplicationFiled: April 5, 2022Publication date: December 29, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshiki Kitajima, Norinao Watanabe, Yutaka Nakamura, Naoya Kajita, Kenji Nakano, Takafumi Sannomiya, Yasutada Shimizu, Kohei Yasuda

Publication number: 20220402421Abstract: A vehicle transporting device includes a bogie frame, a total of eight arms, upper surface plates, and arm driving units. Two arms in a longitudinal direction of the bogie frame of the total of eight arms are paired with each other to support tires. The upper surface plates extend in a width direction of the bogie frame to support the arms. At least six arm driving units are provided on the bogie frame to individually drive at least six arms. Base end portions of pivoting arms are pivotably supported by the upper surface plates in outer peripheral regions of the upper surface plates. Tip portions of the pivoting arms are located outside the upper surface plates. One ends of the arm driving units are attached partway through the pivoting arms. The other ends of the arm driving units are located outside the bogie frame.Type: ApplicationFiled: April 13, 2022Publication date: December 22, 2022Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshiki Kitajima, Norinao Watanabe, Yutaka Nakamura, Kohei Yasuda

Patent number: 11379224Abstract: A source code analysis unit identifies dependency strengths of one or more functions included in a source code. An influence analysis unit identifies one or more transfer functions that will each move to a different subsystem due to refactoring and identifies a dependency strength to be influenced by the refactoring, based on the dependency strengths that have been identified by the source code analysis unit with respect to the one or more transfer functions. A scale calculation unit calculates the scale of the refactoring, based on the dependency strength to be influenced, which has been identified by the influence analysis unit.Type: GrantFiled: February 16, 2017Date of Patent: July 5, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Natsuko Fujii, Toshihiro Kobayashi, Yuki Hikawa, Takahiro Akimoto, Satoshi Maekawa, Toshiki Kitajima

Patent number: 11176178Abstract: In a requirement analysis apparatus, a connection analysis unit classifies a plurality of requirement items into groups based on connections between requirement items indicated in item connection information. A subsystem analysis unit extracts the number of subsystems that are reached by tracing the connections from each requirement item, based on the connections between the requirement items indicated in the item connection information and based on the connection between each requirement item indicated in the item connection information and each subsystem. A result display unit displays, for each requirement item of the plurality of requirement items, analysis result information which is set with an identifier identifying a group into which the requirement item has been classified, and the number of subsystems being reached by tracing the connections from the requirement item.Type: GrantFiled: January 31, 2017Date of Patent: November 16, 2021Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Takahiro Akimoto, Toshihiro Kobayashi, Toshiki Kitajima, Yasuo Hosotani

Patent number: 6209948Abstract: A vehicle body front structure and an impact absorbing method thereof, in which an impact force applied to front side members is efficiently absorbed by an intended deformation of a reinforcing member. A part of the impact force applied to the front side members (12) is received by supporting forces in axial directions of a dash cross member (20) and a pillar brace (22). A recess (24) is provided in the dash cross member (20) in the portion thereof connected with the front side member (12). A recess (26) is provided in the pillar brace (22) in the portion thereof connected with the front side member (12). Due to the dash cross member (20) and the pillar brace (22) compressively deforming in the axial directions starting at these recesses (24), (26), the dash cross member (20) and the pillar brace (22) absorb impact force which is applied to the front side members (12) from the front of the vehicle.Type: GrantFiled: August 10, 1998Date of Patent: April 3, 2001Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takeo Mori, Toshiki Kitajima
