Filed:

Dec 8, 1998

Appl. No.:

9/207737

Inventors:

Jean F. Depatie - Albion NY
Teresa C. Mayer - Rochester NY
Robert A. Bovenzi - Rochester NY
Martin P. Farcella - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03B 908
H02K 127
H02K 500
H02K 2112

US Classification:

396463

Abstract:

An aperture/shutter system defining an optical path comprises a shutter mechanism operable at a first state to selectively block light along the optical path and a second state to allow light along the optical path; and a motor including a stator and an annular rotor. The rotor is rotably supported within the stator by a support that is (i) stationary with respect to the stator and (ii) engages an inner surface of the rotor. The rotor is coupled to the shutter mechanism to move the shutter mechanism between the first state and the second state.

International Classification:

G03B 908

US Classification:

396449

Abstract:

According to the present invention, an aperture/shutter system comprises a stator, a homogeneous rotor and at least one shutter blade. The rotor is located adjacent to the stator and has at least one positioning feature; and the shutter blade has a complimentary feature coupled directly to the positioning feature so as to be directly rotatable by the rotor.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G02B 702

US Classification:

359819

Abstract:

An optical element assembly includes at least first and second optical elements. Each element has molded extensions to assist in the mounting. A pair of pins extend from the extensions on one element and fit into a pair of openings on the extensions of the other element. A clip having a hole in one leg to fit over the pin is positioned to urge each set of extensions together to prevent axial movement of one element with respect to the other.

International Classification:

G03B 908

US Classification:

396463

Abstract:

According to one aspect of the present invention, an imaging apparatus includes an annular motor with a central opening and a plurality of lens elements positioned inside the central opening. The motor includes a stator and a homogeneous cylindrical rotor. This rotor is positioned inside the stator and is 0. 5 mm to 1. 5 mm thick and 2. 5 mm to 5 mm long. According to one embodiment of the present invention the rotor is characterized by an outer cylindrical surface defined by its circumference. The rotor has a plurality of magnetic poles, and the ratio of the circumference of the outer cylindrical surface to the number of magnetic poles is between 1 and 2.

International Classification:

G03B 1700
G03B 1712
G03B 1714

US Classification:

396 73

Abstract:

A dual lens camera has a lens carrier with a shorter focal length lens and a longer focal length lens for alternatively positioning only one of the lenses at a picture-taking axis. A single aperture for each one of the lenses is movable forward and rearward along the picture taking axis. The lens carrier is movable forward and rearward along the picture-taking axis in unity with the aperture, and is movable relative to the aperture to position the shorter focal length lens at the picture-taking axis when the aperture is moved rearward along the picture-taking axis and to position the longer focal length lens at the picture-taking axis when the aperture is moved forward along the picture-taking axis.
