Patent number: 9835185Abstract: A hydraulic mechanism is mounted on a forklift. The hydraulic mechanism has a control valve and a pressure compensation circuit for compensating pressure within the hydraulic mechanism. The pressure compensation circuit has a relief pressure valve and an unloading valve for releasing pressure within the pressure compensation circuit to a discharge oil passage. Upon instructed to perform cargo handling operation, the unloading valve is switched to an open state, and the relief pressure valve is thereby actuated, so that rapid increase of pressure within the circuit is avoided. Further, the unloading valve is switched to an open state, and the pressure within the hydraulic mechanism is thereby released to the discharge oil passage, so that the cargo handling operation by the tilt cylinder and the lift cylinder is restricted.Type: GrantFiled: March 24, 2015Date of Patent: December 5, 2017Assignees: KABUSHIKI KAISHA TOYOTA JIDOSHOKKI, NISHINA INDUSTRIAL CO., LTD.Inventors: Kenichi Hagino, Tetsuya Goto, Shigeto Nakajima, Takahiro Koyama, Satoshi Takano

Patent number: 9812302Abstract: In a magnetron sputtering apparatus configured such that a magnetic field pattern on a target surface moves with time by means of a rotary magnet group, it is to solve a problem that the failure rate of substrates to be processed becomes high upon plasma ignition or extinction, thereby providing a magnetron sputtering apparatus in which the failure rate of the substrates is smaller than conventional. In a magnetron sputtering apparatus, a plasma shielding member having a slit is disposed on an opposite side of a target with respect to a rotary magnet group. The distance between the plasma shielding member and the substrate is set shorter than the electron mean free path or the sheath width. Further, the width and the length of the slit are controlled to prevent impingement of plasma on the processing substrate. This makes it possible to reduce the failure rate of the substrates.Type: GrantFiled: March 14, 2008Date of Patent: November 7, 2017Assignees: NATIONAL UNIVERSITY CORPORATION TOHOKU UNIVERSITY, TOKYO ELECTRON LIMITEDInventors: Tadahiro Ohmi, Tetsuya Goto, Takaaki Matsuoka
