Patent number: 9073525Abstract: In a brake apparatus, an activation current for opening a simulator cut valve from a closed state is applied, whereupon a steady-state current is applied continuously to maintain the open state. A brake control apparatus and a brake control method are employed to perform control in which a valve opening current, which is higher than the steady-state current, is applied to the simulator cut valve every time a brake pedal is depressed. Thus, in a brake apparatus including a switch valve that is driven steadily by applying the steady-state current thereto, favorable control responsiveness can be maintained in the switch valve at all times while achieving a reduction in power consumption.Type: GrantFiled: July 18, 2008Date of Patent: July 7, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tsukasa Fukasawa, Takahiro Okano, Daisuke Nakata, Eiji Nakamura

Patent number: 9033623Abstract: At a contact step in a tool radius adjusting method, a reference portion of a movable body provided radially movably on a housing of a boring tool and a position adjusting reference member fixed on a machine tool are brought into contact by sliding the movable body relative to the housing so that the position of a cutting blade comes to a predetermined position in a direction to go away from a rotational axis. Then, at an adjusting step, the position of the cutting blade relative to the rotational axis is adjusted by changing the relative position between a tool spindle holding the boring tool and the position adjusting reference member in a direction to come close to each other by drive mechanisms of the machine tool used for positioning a spindle head with the tool spindle relative to a workpiece in machining the workpiece with the cutting blade.Type: GrantFiled: November 10, 2010Date of Patent: May 19, 2015Assignee: JTEKT CORPORATIONInventors: Eiji Nakamura, Akihiko Kadota, Takashi Yokoyama, Yasuhiro Komai, Harumi Sawaki, Shun Sawaki, Aya Sawaki, Taku Sawaki
