Patent number: 9045240Abstract: A flight control method and device for correcting a reference trajectory based on a distance from a current position to a target position in a spacecraft in flight. A CPU included in the spacecraft generates a reference trajectory which is a trajectory for allowing the spacecraft in flight to arrive at the target position on a celestial body with the atmosphere, and which is identified based on velocity or energy of the spacecraft and on drag acceleration of the spacecraft. The CPU calculates a ratio between the range that is a distance from the current position based on the reference trajectory to the target position, and the real range that is a real distance from a current position to the target position, and corrects the reference trajectory by calculating the drag acceleration in the reference trajectory using the calculated ratio.Type: GrantFiled: July 11, 2012Date of Patent: June 2, 2015Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Tetsuya Nagase, Atsushi Sasaki

Patent number: 8199391Abstract: At least one exemplary embodiment is directed to a first airflow guide device covering an upper portion of a polygon mirror and having respective opening portions in an upper surface and a lower surface. The lower surface opening portion can have an annular wall opened in the direction all around the perimeter of the polygon mirror, facilitating an airflow path capable of circulating an airflow between the upper surface opening portion and the lower surface opening portion. Thus, airflow generated in a vertical direction in association with the rotation of the polygon motor, is guided, and variations in pressure applied to the polygon motor are reduced, thus facilitating an increase in the rotation accuracy of the polygon motor.Type: GrantFiled: August 22, 2006Date of Patent: June 12, 2012Assignee: Canon Kabushiki KaishaInventor: Tetsuya Nagase
