Abstract: To provide a lens barrel suitable for miniaturization, in a lens barrel having a first lens barrel that holds a first lens and an optical unit, the first lens barrel and the optical unit are disposed adjacent to each other, an annular portion of the first lens barrel has first protruding portions in two or more phases, the first protruding portion regulates a position of the first lens in an optical axis direction, a second protruding portion of the optical unit is disposed in a phase other than the phase having the first protruding portion, and a part of the first protruding portion and a part of the second protruding portion are disposed in the same plane perpendicular to the optical axis.

Abstract: A hard disk drive flexible printed circuit (FPC) includes a plurality of fingers extending from a main portion, with each finger having a first wiring layer including a first electrically conductive trace layout, a second wiring layer including a second electrically conductive trace layout, and a base film interposed between the first and second wiring layers, where the first conductive trace layout includes at least one thermally conductive protective island overlaying a respective portion of the second trace layout to provide a protective thermal barrier to the base film. Hence, maximum temperatures across various layers of the FPC laminate can be reduced, damage to the FPC prevented, and manufacturing yields improved.

Abstract: Provided is a driving device including: a lens holder configured to hold an optical lens; a vibration wave motor including a movable-side rail member; a spherical member configured to connect the movable-side rail member and the lens holder to each other and transmit power; and a lens-barrel urging spring configured to urge the lens holder toward the movable-side rail member, wherein the spherical member and the lens-barrel urging spring are arranged at different positions when seen from an optical axis direction.

Abstract: An image shake correction unit includes a base member, a yoke, a lens holding member, a driving unit, a rotation suppression unit configured to restrict rotation of the lens holding member around an optical axis of the lens unit, and a biasing member configured to bias the lens holding member toward the base member in a direction of the optical axis. The driving unit and the rotation suppression unit are disposed to satisfy a predetermined condition in a case where the image shake correction unit is viewed from the direction of the optical axis. Further, the biasing member has one end provided on the rotation suppression unit and the other end provided on the base member.

Abstract: A secondary battery includes a cathode, an anode including an active material, and non-aqueous electrolytic solution. The active material includes a center portion and a covering portion provided on part or all of the center portion. The center portion includes silicon, tin, or both as constituent elements. The covering portion includes a plurality of fibrous carbon materials. Part or all of the fibrous carbon materials extend in a direction along a surface of the center portion and are closely attached to the center portion.

Abstract: The optical driver apparatus is detachably attachable to an optical apparatus. The optical apparatus includes a lens operation member operable manually, and a locking mechanism switchable between a locking state of restraining motion of the lens operation member and an unlocking state of releasing the restraint. The optical driver apparatus includes a driver operation member, an actuator configured to move the lens operation member, and a controller configured to control the actuator. The controller is configured to drive the actuator in response to an operation of the driver operation member when the locking mechanism is in the unlocking state and to control the actuator, when the locking mechanism is in the locking state, so as to provide one of a state of not driving the actuator in response to the operation of the driver operation member and a state of performing a warning operation.

Abstract: A camera system includes an interchangeable lens including an image-pickup optical system, a camera body including an image sensor, and an adapter attached between the interchangeable lens and the camera body. The adapter includes a lens side mount to which the interchangeable lens is detachably attached, a camera side mount detachably attached to the camera body, and a tilt-shift unit configured to provide at least one of a tilt operation and a shift operation. A flange focal length of the interchangeable lens is longer than a flange focal length of the camera body. A length of the adapter from the lens side mount to the camera side mount in an optical axis direction is equal to or smaller than a difference between the flange focal length of the interchangeable lens and the flange focal length of the camera body.
