Patent number: 10081353Abstract: It is determined whether or not an automatic transmission is in a pre-gear shift state determined in advance prior to a power-ON gear shift in which torque-down control is performed. When the automatic transmission is in the pre-gear shift state, since a required free capacity is secured in a capacitor, torque-down control of a second motor generator is performed in a gear shift, and even if surplus power is generated in a power supply circuit due to the torque-down control, the surplus power can be quickly absorbed using the capacitor. Since a required free capacity is secured in the capacitor by determining whether or not the automatic transmission is in the pre-gear shift state, a predetermined free capacity does not need to be secured constantly, normal capacitor storage control focusing on drivability or the like can be performed normally, and use restriction of the capacitor is minimized.Type: GrantFiled: December 23, 2016Date of Patent: September 25, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Daiki Sato

Publication number: 20180264530Abstract: Each time a highly-viscous substance is extruded, a variation in weight of each cut piece of the highly-viscous substance is minimized. Metallic sodium (5) loaded in an extruder main body (3) is extruded from a nozzle (7) of the extruder main body (3) with a pressing tool (4) and, when it is detected that the metallic sodium (5) is extruded to a predetermined position, the movement of the pressing tool (4) is stopped and the extruded metallic sodium (5) is cut. In this case, an impulse (P) after stop is brought closer to a constant value until a load no longer acts on the metallic sodium (5) in the extruder main body (3) after stopping the movement of the pressing tool (4) by adjusting the movement speed of the pressing tool (4).Type: ApplicationFiled: May 15, 2015Publication date: September 20, 2018Inventors: Koichi HOMMA, Masaaki NIIRO, Daiki SATO

Patent number: 9291173Abstract: A pump motor of a hydraulic hybrid system also serves as a pump to supply hydraulic oil or lubricating oil to a power train, thus enabling elimination of an oil pump provided in the power train and hence reductions in the number of parts and cost, and, in addition, an existing oil pan provided in the power train and the like are utilized for the hydraulic hybrid system, which in turn enables achieving further reductions in the number of parts and cost. Moreover, when idle-reduction control is performed on an engine, during engine's stopped conditions, the pump motor can be driven as a motor by hydraulic pressure accumulated in an accumulator to start the engine and supply the hydraulic pressure to a transmission, thus eliminating a need to provide a motor-driven oil pump for the idle-reduction control and hence enabling a further reduction in cost.Type: GrantFiled: March 6, 2013Date of Patent: March 22, 2016Assignee: Honda Motor Co., Ltd.Inventors: Seiichiro Ishikawa, Yasunari Kimura, Masashi Kato, Daiki Sato, Yuki Shibahata
