Patent number: 8992687Abstract: Processing gas is supplied from the central upper part of a processing chamber to a wafer on a mounting board, while the processing chamber is exhausted from processing gas exhaust passages at areas outside of the wafer. In addition, purge gas is supplied from purge gas supply passages to a buffer chamber formed between the peripheral part of a container main body and that of a cover body. The supplied flow-rate of the processing gas is made less than the exhaust flow-rate in the processing gas exhaust passages. Accordingly, the purge gas in the buffer chamber is drawn into the processing chamber via a purge gas supply hole formed of a gap between the container main body and the cover body due to a negative pressure inside the processing chamber caused by a difference between the flow rates.Type: GrantFiled: August 26, 2011Date of Patent: March 31, 2015Assignee: Tokyo Electron LimitedInventors: Hiroyuki Kudoh, Hideto Mori, Shinji Okada, Toyohisa Tsuruda

Patent number: 8882149Abstract: A steering device is provided that includes an aluminum-alloy column bolted with a steering lock apparatus, that prevents destruction of a flange to be bolted, and that prevents the bolt from being loosened by applying shock to a bolt head section through the use of a special tool. A counterbore is formed so deep that a slant plane is higher than a top end of a disk-shaped member of a bolt. A thief can hardly apply shock to the disk-shaped member of the bolt using a special tool. It is difficult to rotate and loosen the bolt.

Patent number: 8707818Abstract: A steering device is provided in which fastening of a column is carried out smoothly, meshing of a movable tilt lock gear and a fixed tilt lock gear is carried out smoothly when tilting is clamped, and a rigidity can be increased when the tilting is clamped. A side plate on a left side to which a fixed tilt lock gear is attached is restrained from being elastically deformed by a rib. Therefore, in tilting and clamping and telescopically clamping, positions of the fixed tilt lock gear and a movable tilt lock gear in a vehicle width direction relative to each other is not varied, and therefore, the movable tilt lock gear and the fixed tilt lock gear are brought in mesh with each other smoothly.Type: GrantFiled: July 27, 2011Date of Patent: April 29, 2014Assignee: NSK Ltd.Inventors: Shinji Okada, Kou Yamamoto

Patent number: 8689660Abstract: A steering device provides a driver operation feeling that lets the driver definitely feel that a movable tilt lock gear and a fixed tilt lock gear are securely engaged. Gear noise in tilt adjustment when the movable tilt lock gear and the fixed tilt lock gear are engaged halfway is prevented. As the control force of an operating lever is rapidly decreased when a fitting protrusion is fitted to a stepped part, a click and click stop feeling occur and a definite operation feeling that the clamping is securely performed is acquired. As the fitting protrusion is integrated with the operating lever and a sliding surface configured by a groove, an inclined face and the stepped part are also formed as an outside face of the fixed tilt lock gear, the number of parts and man-hours for assembly can be reduced.Type: GrantFiled: August 29, 2011Date of Patent: April 8, 2014Assignee: NSK Ltd.Inventor: Shinji Okada

Patent number: 8677856Abstract: A steering device facilitates assembly of a tilt lock mechanism, which elastically supports movement of a movable tilt lock gear to a stationary cam in a tilt direction via a spring. When a cylindrical part of a tilt stopper is inserted into a through hole, the cylindrical part enlarges in diameter, and surfaces of engagement projections engage with an end surface of an inclined cam surface side of the stationary cam. A right end surface of a tilt stopper flange part abuts against an end surface of the movable tilt lock gear. The movable tilt lock gear, a wire spring, and the stationary cam are integrated by the tilt stopper, and are prevented from being dispersed during transport. As a result, the assembly time can be reduced.Type: GrantFiled: July 14, 2011Date of Patent: March 25, 2014Assignee: NSK Ltd.Inventors: Shinji Okada, Yuuichi Tomaru

Patent number: 8671796Abstract: A steering device reduces a sliding sound and an impact sound between a movable tilt lock gear and an outer surface of a side plate of a vehicle body attachment bracket. When a movable tilt lock gear is rotated, and a thread of an inclined cam surface of a stationary cam runs on a thread of an inclined cam surface of a movable cam, a fastening rod is pulled toward a left side, and the movable tilt lock gear is pushed toward an outer surface of a left side plate. Because a first buffer member and a second buffer member are attached to the movable tilt lock gear, sliding surfaces of the first buffer member and a sliding surface of the second buffer member contact the outer surface of the left side plate, and slide, to suppress the sliding sound.Type: GrantFiled: July 14, 2011Date of Patent: March 18, 2014Assignee: NSK Ltd.Inventors: Shinji Okada, Yuuichi Tomaru

Patent number: 8661930Abstract: A steering device smoothly moves a variable tilt lock gear in a tilt direction, smoothly engages the movable tilt lock gear with a stationary tilt lock gear, and facilitates the assembling. When a movable tilt lock gear is not well engaged with a stationary tilt lock gear, and the respective threads of a gear of the movable tilt lock gear and a gear of the stationary tilt lock gear are abutted against each other, arm parts of a wire spring are elastically deformed by its reaction force. As a result, the movable tilt lock gear is slightly moved in the vertical direction of the vehicle body while the stationary cam is fixed, and the gear of the movable tilt lock gear and the gear of the stationary tilt lock gear are normally engaged with each other.Type: GrantFiled: July 14, 2011Date of Patent: March 4, 2014Assignee: NSK Ltd.Inventors: Shinji Okada, Yuuichi Tomaru
