Patent number: 9346442Abstract: When a brake switch is switched from OFF to ON, current is applied to a brake ECU, and a command to switch a master cylinder from a second state to a first state is issued after a lapse of preparation time, so that switching-time change suppression control is performed. A reservoir shutoff valve is closed, and duty control is performed on a communication control valve. The duty ratio is set to 1 when a switching-time control duration expires, and the communication control valve is placed in an open position, to establish the first state. Thus, since the communication control valve is duty-controlled during switching from the second state to the first state, change in the hydraulic pressure of an input chamber is suppressed, and change of the operating feeling is suppressed.Type: GrantFiled: March 27, 2013Date of Patent: May 24, 2016Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, ADVICS CO., LTD.Inventors: Yusuke Kamiya, Akira Sakai, Kiyoyuki Uchida, Masaki Maruyama, Yoshio Masuda, Hiroaki Niino, Takashi Kurokawa

Patent number: 9126523Abstract: Provided is a vehicle that elevates a working beam installed between a pair of booms with a working beam elevating unit and can ensure the area of a load receiving surface where a load is loaded. The working beam elevating unit is received in a working beam and one end of a chain is fixed to a boom. Therefore, the working beam is moved up/down by loosening and retracting the chain. Therefore, as the working beam elevating unit is installed at the working beam, it is not necessary to ensure a space for installing the working beam on a vehicle body. Therefore, it is correspondingly possible to enlarge the space (area of the load receiving surface) on the vehicle for loading a load.Type: GrantFiled: August 3, 2012Date of Patent: September 8, 2015Assignees: CENTRAL JAPAN RAILWAY COMPANY, NIPPON SHARYO, LTD.Inventors: Noriyuki Ogita, Kazunari Sakurai, Ryou Maeda, Kazuki Kobayashi, Koshu Yamashita, Akihiko Go, Toshihiko Nishio, Yoshio Masuda

Patent number: 9085259Abstract: There is provided a vehicle which can stably load or unload a long heavy load and lower a height of a working space necessary for loading or unloading the weight body. The loading/unloading apparatus suspends and maintains a load in a working beam installed between a pair of booms and rotates the pair of booms toward the left or right direction of a vehicle body, such that the load is unloaded from the vehicle body in a construction field or loaded from the construction field onto the vehicle body.
