Patent number: 11422363Abstract: The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.Type: GrantFiled: February 22, 2019Date of Patent: August 23, 2022Assignee: INTER-UNIVERSITY RESEARCH INSTITUTE CORPORATION NATIONAL INSTITUTES OF NATURAL SCIENCESInventors: Masayuki Hattori, Yosuke Tamada, Takashi Murata, Yasuhiro Kamei, Mitsuyasu Hasebe, Yutaka Hayano, Shin Oya

Patent number: 5561185Abstract: There is disclosed a fire-retardant resin composition, comprising a polypropylene-series resin (a), a modified polyethylene modified with an unsaturated carboxylic acid or its derivative (b), a metal hydrate (c), and an ethylene-series copolymer (d), in a specific ratio; and an electric wire with a cover layer formed on the circumference of a conductor, in which the cover layer is composed of a composition prepared by blending (c) a metal hydrate with, in a specific ratio, a resin mixture, containing (a) a polypropylene-series resin, (b) a modified polyethylene, and (d) an ethylene-series copolymer.The fire-retardant resin composition is excellent in tensile strength, heat resistance, extrudability, and moldability. The covered electric wire is excellent in electric-wire properties and good in the end workability.Type: GrantFiled: November 7, 1994Date of Patent: October 1, 1996Assignees: The Furukawa Electric Co., Ltd., Ube Industries, Ltd.Inventors: Dai Hashimoto, Masaki Nishiguchi, Shinichi Irie, Yoshihiro Inuizawa, Yasuhiro Kamei

Patent number: 5050459Abstract: In a hydraulic control system for an automatic transmission comprising a hydraulic servomotor C-2 for a clutch or brake adapted to engage and disengage necessary rotary components of a planetary gear mechanism, and a select valve for selectively supplying hydraulic pressure to the hydraulic servomotor C-2 dependent on two transmission states, the select valve has two input ports selectively supplied with hydraulic pressure dependent on the two transmission states and one output port for outputting hydraulic pressure to the hydraulic servomotor C-2, a first orifice is disposed between the output port and the hydraulic servomotor C-2, and a second orifice is disposed on the same side as either of the two input ports.Upon an upshift from the 2nd to the 3rd speed in the D range condition, a shift valve is changed over such that the line pressure is supplied to one input port of the select valve via a line pressure output port and the second orifice to move a ball valve body in the select valve.Type: GrantFiled: April 17, 1990Date of Patent: September 24, 1991Assignees: Alsin-Aw Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Kazunori Ishikawa, Yasuhiro Kamei, Yutaka Taga, Kunihiro Iwatsuki
