Patent number: 7687973Abstract: In a friction drive actuator 1 according to the invention, a rotor 2 and a stator 4 are held in contact at a plurality of positions by a plurality of vibrators 3, and at least one of the vibrators 3 vibrates to rotate the rotor 2 relative to the stator 4. Accordingly, the rotor 2 is supported without using a bearing and, hence, the rotor 2 can be more easily elastically deformed as compared with the case where the rotor 2 and the stator 4 are held in contact over the entire circumference. Therefore, a frictional force between the stator 4 and the rotor can be stabilized.Type: GrantFiled: June 3, 2008Date of Patent: March 30, 2010Assignee: Konica Minolta Opto, Inc.Inventors: Akihiro Oki, Shigeaki Tochimoto, Takashi Matsuo

Publication number: 20050001356Abstract: In a 3D product forming apparatus, a nozzle head includes nozzles that respectively jet binders colored in yellow, magenta, cyan, and a nozzle that jets a binder colored in white. A powder layer can be formed on a product forming stage, and the binders are jetted onto the formed powder layer from the nozzle head. At a predetermined region in the powder layer, the powder is bound by the binders. The binders are jetted each time when a powder layer is laminated in forming a plurality of successively laminated powder layers, thereby to form a 3D product on the product forming stage. This allows the product to be colored as well in the product forming process. As a result, 3D products colored in various colors can be created in a short time and at a low cost.Type: ApplicationFiled: August 2, 2004Publication date: January 6, 2005Applicant: MINOLTA CO., LTD.Inventors: Shigeaki Tochimoto, Naoki Kubo
