359233000 | With relative motion of two apertured elements | 8 |
20090153937 | LIGHT QUANTITY CONTROL DEVICE - A light quantity control device includes: a bottom board having an opening; a first blade and a second blade linearly moving in opposing directions and changing in an opening area of the opening; a supporting blade overlapping the first blade and closing the opening in cooperation with the first blade and the second blade; and a driving lever connected to the first blade, the second blade, and the supporting blade, and driving the first blade, the second blade, and the supporting blade by rotation of the driving lever. The first blade and the supporting blade are engaged with an identical pin provided in the driving lever. The first blade and the supporting blade are misaligned in such a way to reduce an overlapping degree of the first blade and the supporting blade. The first blade and the supporting blade bring the opening to the fully closed state in cooperation with the second blade. | 06-18-2009 |
20100053718 | OPTICAL SYSTEM FOR MERGING A FIRST AND A SECOND PARTIAL IMAGE BEAM, EACH PROCEEDING FROM A SPECIMEN, INTO A RESULTANT IMAGE BEAM - An optical system is described for merging a first and a second partial image beam emanating from a specimen into a resultant image beam allowing modification of the areal proportion of the respective first or second partial image beam in the resultant image beam. A stop arrangement comprises at least a first and a second movable stop element each comprising at least one stop region adapted to be brought into a working position with the first or second partial image beam. Movably arranged connecting means for connecting the two stop elements are provided to modify the respective areal proportions of the partial image beams in the resultant image beam by movement of the connecting means. | 03-04-2010 |
20100110519 | DOMESTIC VIEWING PANEL UNIT - A domestic viewing panel unit for a door, comprising: a first panel comprising one or more first panel light transparent regions that are substantially transparent to visible light and one or more first panel light hindering regions which substantially hinder transmission of visible light; a second panel comprising one or more second panel light transparent regions that are substantially transparent to visible light and one or more second panel light hindering regions which substantially hinder transmission of visible light; an actuator for moving the second panel relative to the first panel in a plane parallel to the plane of the first panel; wherein the first and second panels are arranged such that the amount of visible light transmitted unhindered through the domestic viewing panel is a non-linear function of the relative position of the first and second panels. | 05-06-2010 |
20100157405 | LIGHT AMOUNT ADJUSTING DEVICE AND OPTICAL DEVICE - A light amount adjusting device includes: a board including an opening; a linear moving blade linearly and movably supported by the board; and a swinging blade swingably supported by the board, wherein: the linear moving blade and the swinging blade are receded from the opening to form a fully opened state; the linear moving blade covers the opening to form a fully closed state; and the swinging blade has a small aperture opening with a diameter smaller than a diameter of the opening, and causes the small aperture opening and the opening to be overlapped with each other to form a small aperture state. | 06-24-2010 |
20110085223 | LIGHT ADJUSTING APPARATUS - A light adjusting apparatus includes a substrate ( | 04-14-2011 |
20110164298 | BLADE DRIVE DEVICE AND OPTICAL DEVICE - A blade drive device includes: a board including an optical path opening; first and second blades cooperatively defining an amount of light passing through the optical path opening to a given amount of light. The first blade includes a first opening. The second blade includes: a first cutout portion defining the amount of light in corporation with the first opening; and a second cutout portion defining the amount of light in corporation with the first opening. The second cutout portion overlaps the first blade when the first cutout portion and the first opening cooperatively define the amount of light. | 07-07-2011 |
20110267669 | LIGHT ADJUSTING APPARATUS - There is provided a light adjusting apparatus which is to be used for a small-size image pickup equipment which is easy to assemble. | 11-03-2011 |
20140168740 | FLEXIBLE OPTICAL APERTURE MECHANISMS - A system for providing flexible optical aperture shapes in an optical inspection system (e.g., an optical wafer inspection system) is described. The system includes one or more mechanisms for providing multiple optical aperture shapes along an optical beam path in the optical wafer inspection system. The multiple optical apertures shapes are stacked or overlapped to combine the shapes and form a single combined optical aperture shape along the optical beam path. | 06-19-2014 |
