Publication number: 20240070792Abstract: A VGI system is a system in which electric power is exchanged between a power grid of an electric power utility company and a BEV, and includes a plurality of BEVs, EVSE, and a management server that manages exchange of electric power. The EVSE includes specific EVSE available to a specific vehicle among BEVs, the specific vehicle being permanently permitted to use the EVSE. The management server performs processing for temporarily permitting use of the specific EVSE by a non-specific vehicle different from the specific vehicle on condition that the non-specific vehicle uses the specific EVSE to exchange electric power with the electric power utility company and performs processing for granting an incentive to a user of the non-specific vehicle or a manager of the specific EVSE on condition that the non-specific vehicle has exchanged electric power with the electric power utility company.Type: ApplicationFiled: August 21, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Mitsuaki TOMITA, Maiko HAYASHI, Miyako SAKAI, Makito MURAMATSU, Hirohiko TANIGUCHI

Patent number: 10975503Abstract: A skin material for vehicle interior is bonded to a resinous vehicle interior base. The skin material for vehicle interior includes a woven fabric woven by using synthetic resin fibers, side emission type optical fibers, and heat fusible fibers as warps or wefts. The synthetic resin fibers and the side emission type optical fibers adjacent to the synthetic resin fibers are bonded in respective longitudinal directions thereof by the heat fusible fibers. Even when a plurality of the side emission type optical fibers are woven between the adjacent synthetic resin fibers, the adjacent side emission type optical fibers may be bonded to each other in the longitudinal direction by the heat fusible fibers. The heat fusible fibers may be obtained by twisting multifilaments and heat fusion yarns having a melting point lower than that of the multifilaments, and the multifilaments remain as constituent yarns after the bonding.Type: GrantFiled: May 10, 2018Date of Patent: April 13, 2021Assignees: TOYOTA BOSHOKU KABUSHIKI KAISHA, DAIKI CO., LTD.Inventors: Takamasa Yamada, Hirohiko Sakai, Takayoshi Yamamoto

Patent number: 4312656Abstract: In a float process of flat glass production, the width of a glass ribbon formed by discharging a molten glass onto a molten metal bath is controlled in response to the temperature of a molten glass to be supplied to the molten metal bath by regulating a tweel to manipulate the rate of supplying a molten glass to the bath. Further to minimize a fluctuation of the glass ribbon width, either of two different feedback control modes, an integral control mode and a proportional-plus-integral control mode, is employed depending on whether or not an error between a measured width and a desired value is within a predetermined range of the error. Preferably the control is achieved in accordance with a sampled-data control system.Type: GrantFiled: May 28, 1980Date of Patent: January 26, 1982Assignee: Central Glass Company, LimitedInventors: Hiroshi Masuda, Hirohiko Sakai, Syoji Saito

Patent number: 4306898Abstract: In a float process of flat glass production, the width of glass ribbon is controlled by regulating a tweel to manipulate the rate of supplying a molten glass through the tweel onto a molten metal bath. To minimize a fluctuation of the glass ribbon width, either of two different control modes, an integral control mode and a proportional-plus-integral control mode, is employed depending on whether or not an error between a measured width and a desired value is within a predetermined range of the error. Preferably the method of the present invention is achieved according to a sampled-data control system.Type: GrantFiled: May 28, 1980Date of Patent: December 22, 1981Assignee: Central Glass Company, LimitedInventors: Hiroshi Masuda, Hirohiko Sakai, Syoji Saito
