Patent number: 11586231Abstract: A reaction compensation device includes a drive mechanism driving a first movable part with respect to a base, a reaction mass drive mechanism driving a second movable part with respect to the base; and a first relative position sensor measuring a relative position between the first movable part and the base. There is also a second relative position sensor measuring a relative position between the second movable part and the base, a first control system controlling the drive mechanism by taking in a signal outputted from the first relative position sensor as a feedback signal in response to a command value, and a second control system correcting the command value using a correction parameter for adjusting a difference between mass properties of the drive mechanism and reaction mass drive mechanism and for controlling the reaction mass drive mechanism.Type: GrantFiled: December 26, 2017Date of Patent: February 21, 2023Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Osamu Takahara, Eiji Yokoyama, Kazuhide Kodeki

Publication number: 20220185506Abstract: A formation flight control device for generating and outputting orbit control information for controlling observation satellites in an observation satellite group orbiting a celestial body and sequentially observing a ground surface of the celestial body with an observation interval includes an orbit information acquirer, an orbit control information generator, and an orbit control information outputter. The orbit information acquirer acquires orbit information indicating an observation time of a preceding observation satellite of which an observation order precedes by one, and an orbit of the preceding observation satellite at the observation time.Type: ApplicationFiled: May 14, 2019Publication date: June 16, 2022Applicant: Mitsubishi Electric CorporationInventors: Masanori KAWAMURA, Osamu TAKAHARA, Eiji YOKOYAMA

Publication number: 20210251310Abstract: A down jacket 1 has a face side fabric, a lining and feathers, and in addition, a strip of tape. The strip of tape extends between the face side fabric and the lining along a seam portion and is sewn together with the face side fabric and the lining. The strip of tape has a teaseled portion projecting from a surface of the strip of tape as a trap portion for trapping the feathers accommodated. The teaseled portion is formed on both a side of the strip of tape facing the face side fabric and a side of the strip of tape facing the lining.Type: ApplicationFiled: February 10, 2021Publication date: August 19, 2021Applicant: SANKEI CO., LTD.Inventors: Minoru Kimura, Osamu Takahara
