Patent number: 10557533Abstract: A linear motion mechanism with precise linear motion has structural robustness and allows easy reduction in weight and size, simple production and easy operation. The linear motion mechanism includes: an elastic arrangement which is arranged to transform an input direction and an input displacement to an output direction and an output displacement, wherein the output direction is orthogonal to the input direction; an operating member which is arranged to deform the elastic arrangement in the input direction by the input displacement; and a movable member fixed to the elastic arrangement to move in the output direction by the output displacement.Type: GrantFiled: July 30, 2015Date of Patent: February 11, 2020Assignee: NEC CorporationInventors: Minoru Kurose, Kazuo Hamada, Yoshihiko Katsuyama, Takashi Kamizono, Takuro Kobayashi, Naoto Tanimichi, Tsui Happy

Patent number: 6367285Abstract: In a freeze-concentrating apparatus, an aqueous solution is cooled by a cooling cylinder 22 serving as a heat exchanger for cooling to continuously produce a suspension containing ice crystals. A liquid component is separated and discharged from the suspension to increase the ratio of the ice crystals, and the ice crystals are grown to produce a column-shaped ice cake. The ice cake is cut into an ice pillar of a given length and a concentrated solution is taken out from the ice pillar.Type: GrantFiled: December 13, 1999Date of Patent: April 9, 2002Assignee: Fujisawa Pharmaceutical Co., Ltd.Inventors: Katsuhiko Shinozaki, Hisatoyo Yazawa, Yutaka Yamazaki, Kiyoshi Tenmaru, Yoshio Sugita, Hitoshi Hasegawa, Eiji Sekiya, Akimasa Nakagomi, Heihachi Matsunaga, Yoshihiko Katsuyama

Patent number: 5460341Abstract: A disturbance compensation system for a camera on board a spacecraft and having an imaging device and condensing means for condensing light onto the imaging device. Linear actuators adjust the position of the imaging device by moving it with multifreedom. A control circuit computes, in response to position information associated with the imaging device, an amount in which the position of the imaging device should be corrected, and controls the linear actuators on the basis of the computed amount.Type: GrantFiled: July 28, 1993Date of Patent: October 24, 1995Assignee: NEC CorporationInventors: Yoshihiko Katsuyama, Akinori Sato, Naoki Takizawa
