Patent number: 10414044Abstract: A robot arm includes a first holder and a second holder. The first holder includes a first base portion and a first distal portion. The first distal portion has a first distal thickness smaller than a thickness of the first base portion. The second holder includes a second base and a second distal portion. The second distal portion has a second distal thickness smaller than a thickness of the second base portion. A first rotator is supported by the first distal portion and the second distal portion. A second rotator is supported by the first rotator. A first bevel gear is provided in the first distal portion. Another first bevel gear is provided in the second distal portion. A second bevel gear engages with the first bevel gear and the another first bevel gear.Type: GrantFiled: May 25, 2017Date of Patent: September 17, 2019Assignee: KABUSHIKI KAISHA YASKAWA DENKIInventors: Youichi Motomura, Kentaro Tanaka

Publication number: 20100141923Abstract: There is provided a stage apparatus at low cost by constituting a counter mass constituting a movable portion of the stage apparatus at low cost. In a stage apparatus used for fabrication or for inspection, by fastening two pieces of first frames (1) and two pieces of second frames (2) by bolts in a positional relationship of making the first frames (1) and the second frames (2) respectively opposed to each other, a counter mass constituting a movable portion of the stage apparatus is constituted, by attaching ceramic-made air pads (4) to air pad attaching faces respectively formed at upper faces and lower faces of two pieces of the first frames (1) on both sides in a length direction, four air bearings are constituted at four corners of the counter mass of the stage apparatus, and the counter mass is floated up by the four air bearings.Type: ApplicationFiled: January 25, 2008Publication date: June 10, 2010Applicants: KABUSHIKI KAISHA YASKAWA DENKI, NIKON CORPORATIONInventors: Youichi Motomura, Toshiyuki Kono, Keiichi Tanaka
