Publication number: 20210258456Abstract: A favorable transmission state of rotation power from an operation ring to a rotating element is ensured, and an improvement in responsiveness associated with rotation detection is achieved. An interchangeable lens includes: an operation ring that has a tooth section extending in a rotation direction and that is operated to be rotatable; a rotating element that has a gear section provided in an outer circumferential portion and engaged with the tooth section, a rotation amount of the rotating element being detected by a rotation detection sensor; and a transmission ring that is rotated in proportion to rotation of the operation ring, and that transmits rotation power of the operation ring to the rotating element, in which the transmission ring is pressed against either the operation ring or the rotating element, and the rotating element is rotated by the rotation power transmitted from the operation ring via the transmission ring.Type: ApplicationFiled: April 5, 2019Publication date: August 19, 2021Inventors: REI SAKAMOTO, TOMOHIRO YASUI

Patent number: 8131141Abstract: A lens position detecting device 200 has a position detecting magnet 202, a magnetic force detecting sensor 204, a positional information generating means 206, etc. The position detecting magnet 202 is mounted on a rear surface of a lens holder frame 1460. The magnetic force detecting sensor 204 serves to generate a detected signal having a magnitude depending on the intensity of a magnetic force generated from the magnetic poles of the position detecting magnet 202. The magnetic force detecting sensor 204 is disposed on a straight line that passes through the position detecting magnet 202 parallel to the optical axis. The magnetic force detecting sensor 204 outputs a detected signal having a voltage corresponding (proportional) to the intensity of the magnetic force. An amplifying circuit 208 of a positional information generating means 206 amplifies the detected signal Ss from the magnetic force detecting sensor 204.Type: GrantFiled: August 18, 2005Date of Patent: March 6, 2012Assignee: Sony CorporationInventors: Tomoya Takei, Toshifumi Takaoka, Hideo Takagi, Yoshikazu Ito, Masanori Hayashi, Tomohiro Yasui, Hideki Yamaoka, Kentaro Tashita

Patent number: 7554600Abstract: A main flexible substrate has a mount surface portion to be mounted to the rear surface of a base, and a movable surface portion extended from the mount surface portion. At a portion of the movable surface portion near the mount surface portion, there is provided an undulatable surface portion undulatable between a bent state of being bent relative to the mount surface portion and separate from the rear surface of the base and a flat state of being mated and mounted to the rear surface of the base. A first soldered terminal portion is formed on the front surface of the undulatable surface portion. A base end portion of a shutter flexible substrate extended to the rear side of the rear surface of the base and a base end portion of a coil flexible substrate are each provided with a second soldered terminal portion.Type: GrantFiled: August 22, 2005Date of Patent: June 30, 2009Assignee: Sony CorporationInventors: Tomohiro Yasui, Masanori Hayashi, Kentaro Tashita, Yoshikazu Ito, Hideki Yamaoka

Publication number: 20090092483Abstract: A turbocharger having a variable nozzle mechanism, which is accommodated in an accommodating chamber, is disclosed. The variable nozzle mechanism has a nozzle ring, a nozzle vane, a nozzle vane drive mechanism, and a support ring. The nozzle ring defines a gas passage through which exhaust gas is guided to a turbine wheel. The nozzle vane is supported by the nozzle ring and varies the flow area of the gas passage. The nozzle vane drive mechanism drives the nozzle vane. The support ring is connected to the nozzle ring. The nozzle vane drive mechanism is accommodated in the accommodating chamber as spaced from the nozzle ring through the support ring. The turbocharger has a drain passage that extends through a lower portion of the support ring and reaches the gas passage. The drain passage is located downward from the nozzle vane drive mechanism.Type: ApplicationFiled: September 18, 2008Publication date: April 9, 2009Inventors: Tomohiro Yasui, Shuichi Fujita, Masuo Kawamoto, Tomoyuki Isogai

The second lens holder frame has three guides projecting axially from an outer circumferential portion of an annular plate and disposed at circumferentially equally spaced intervals. Guide grooves are defined in respective portions of the annular plate which are radially inwardly faced by the guides. Guide posts engage respectively in the guide grooves, so that the second lens holder frame is nonrotatably, but axially movably supported by the guide posts.Type: GrantFiled: May 31, 2007Date of Patent: August 26, 2008Assignee: Sony CorporationInventors: Tomohiro Yasui, Masanori Hayashi, Yoshikazu Ito, Hideki Yamaoka, Kentaro Tashita
