Publication number: 20220187805Abstract: It is judged whether a first predicted value of an operation index obtained by inputting a scheduled change value of a manipulation parameter of a plant meets an operation criterion, and whether a second predicted value of the operation index obtained by inputting a virtual change value with a greater change amount from a current value than the scheduled change value to a prediction model meets the operation criterion. If it is judged that the first predicted value and the second predicted value meet the operation criterion, the scheduled change value is output as a command value of the manipulation parameter.Type: ApplicationFiled: March 24, 2020Publication date: June 16, 2022Inventors: Yusuke HAZUI, Masumi NOMURA, Shigeru ANO, Kenta WADA, Koshiro FUKUMOTO

Patent number: 9610925Abstract: According to one embodiment, there is provided a vehicle behavior control system. The vehicle behavior control system includes a behavior stabilization control module that is configured to execute a behavior stabilization control so as to stabilize a behavior of a vehicle by giving a braking force to a turning outer wheel of the vehicle based on a target braking force. The behavior stabilization control module has a target braking force setting section that sets the target braking force. The target braking force is set so as to be smaller for a second turn than for a first turn.Type: GrantFiled: January 29, 2015Date of Patent: April 4, 2017Assignee: AUTOLIV NISSIN BRAKE SYSTEMS JAPAN CO., LTD.Inventors: Nobuyuki Nomura, Takahiro Nishigaki, Shinji Murashita, Natsuko Hamamoto, Kenta Wada

Patent number: 7234290Abstract: In manufacturing an aspherical seamless capsule comprises, firstly, a seamless capsule C1 having a filler encapsulated with a shell membrane is provided, then it is dried in a dryer 12 until a predetermined percentage content of solvent in the shell membrane reaches a predetermined value. Subsequently, the seamless capsule is heated by a heater 38 so that the shell material may get to a semi-sol state. Then, the heated seamless capsule is formed into an aspherical shape using a forming machine such as a compression molding machine. Because the spherical seamless capsule has a shell membrane which is dried to get semi-sol so that it may have a reduced elasticity and a shortened stress relaxation time, the capsule can be formed in a short time and suppressed from restoring to the original spherical shape. The semi-sol shell membrane has almost no change in properties, and so allows easiness in temperature control for treatment.Type: GrantFiled: June 20, 2003Date of Patent: June 26, 2007Assignee: Chugai Seiyaku Kabushiki KaishaInventors: Takeshi Nakamura, Toshinari Taira, Kenta Wada, Katsuya Otomo
