20100226642BARRIER UNIT - A barrier unit is provided that suppresses reflection of light at end faces of blades when the blades are in an open state and that prevents the blades from riding on top of each other. The barrier unit includes a base; and a pair of blades mounted on the base, the pair of blades being configured to be positioned in an open state and a closed state and to contact each other at predetermined end faces of the blades in the closed state. An inclined portion is provided at a central portion in a longitudinal direction, of each predetermined end face of the blades, the inclined portion defining a plane inclined with respect to an optical axis of a lens. A parallel portion is provided on both sides of the inclined portion of each predetermined end face of the blades, the parallel portion defining a plane parallel to the optical axis.09-09-2010
20100321783METHOD OF MAKING ANTIREFLECTIVE ROUGHENED SURFACE AND LENS BARREL WITH ROUGHENED SURFACE MADE BY THE METHOD - A method of turning the surface of a die, which is used to make a product, into an antireflective roughened one includes the steps of: a) producing a first roughness on the surface of the die; and b) producing a second roughness, which is smaller than the first roughness, on the surface of the die on which the first roughness has already been produced.12-23-2010
20100322616BARRIER UNIT - The present invention provides a barrier unit, of which the blades can be opened fully.12-23-2010
20100329663BARRIER UNIT - The present invention provides a barrier unit structure that can avoid not only ruining the appearance of a barrier unit due to a vertical misfit of blades that contact with each other at their edges when closed but also interfering with smooth movement of the blades due to their unintentional overlap.12-30-2010
20110002684BARRIER UNIT - A barrier unit, of which the cap edge is not easily deformed even under some external force, is provided.01-06-2011
20110019290LENS BARREL AND IMAGING DEVICE - A lens barrel includes a first support frame and a second support frame. The first support frame has a cam groove. The second support frame has an annular main body with a cam follower that extends outwardly in a radial direction. The cam follower is slidably disposed in the cam groove and has a first cam portion, a second cam portion and a connecting portion. The second cam portion is aligned with the first cam portion along the circumferential direction of the main body. The connecting portion connects the first cam portion and the second cam portion to create a space between the connecting portion and the cam groove.01-27-2011
20110019291LENS BARREL AND IMAGING DEVICE - The lens barrel of the present invention includes: a lens; and a light blocking member provided in the vicinity of the lens for blocking part of light traveling toward the lens, a main constituent of the light blocking member being a polymer alloy resin.01-27-2011
20110026146LENS BARREL AND IMAGING DEVICE - The lens barrel of the present invention includes: a lens; and a light blocking member provided in the vicinity of the lens for blocking part of light traveling toward the lens, a main constituent of the light blocking member being a thermoplastic elastomer resin.02-03-2011
20110115975IMAGING DEVICE - To produce a subject's image on an imager as accurately as possible, a technique that is effectively applicable to the process of assembling an optical system is provided.05-19-2011
