Patent number: 6538348Abstract: In a state that a wafer stage is not positioned in the center of the Y-direction traveling range, thrusts Fa, Fb supplied from a pair of linear motors to a Y-direction stage are made different and the Y-direction stage is moved in the X direction so that moments Ma, Mb about the centroid of the Y-direction stage by the thrusts Fa, Fb cancel each other. Since the moments Ma, Mb about the centroid generated by the thrusts cancel each other and the thrusts do not act as forces for rotating the Y-direction stage, the Y-direction stage is not deflected in a yawing direction. Such a stage device as constructed above can prevent deflection in a yawing direction due to displacement of the centroid position of an object to be positioned or a stage and precisely move the object to be positioned to a target position.Type: GrantFiled: February 21, 2001Date of Patent: March 25, 2003Assignee: Sharp Kabushiki KaishaInventors: Hiroyuki Sawai, Hiroshi Ishii

Patent number: 6428143Abstract: To provide an ink jet image forming method and an ink jet image forming device capable of forming an image of superior quality by using quickly drying ink and slowly drying ink in combination, wherein deviation which may occur in a discharge position of ink causes no reduction in the resolution of the image, black ink is adopted as the slowly drying ink, and so is white ink as one of the quickly drying ink. A white dot is formed with the white ink in a position to form a black dot on white recording paper, thereafter applying the black ink thereto. Deviation which may occur in the discharge position of the quickly drying white ink on the recording paper thus becomes almost visually unnoticeable.Type: GrantFiled: March 7, 2001Date of Patent: August 6, 2002Assignee: Sharp Kabushiki KaishaInventors: Kouichi Irihara, Hiroyuki Sawai

Patent number: 6332260Abstract: In an annular member forming apparatus including: a forming roll rotatable in contact with an outer cylindrical surface of an annular workpiece; a mandrel relatively movable towards and away from the forming roll in contact with an inner cylindrical surface of the workpiece; and an outside diameter detecting device for detecting an outside diameter of the workpiece which is to be worked, the apparatus further includes a moving device for moving relatively the forming roll and the mandrel and for pressing the workpiece by the forming roll and the mandrel moved towards each other to subject the workpiece to rough rolling and to finish rolling. The moving device includes a retracting device for correcting an elastic deformation of the forming roll, the mandrel and the moving device occurring during the rough rolling, for a switching time from the rough rolling to the finish rolling by an output signal from the outside diameter detecting device.Type: GrantFiled: April 13, 2000Date of Patent: December 25, 2001Assignee: NSK Ltd.Inventors: Chuichi Sato, Hiroyuki Sawai, Hiroshi Mitsuboshi
