the upper part of the base seat is provided with the electric motor and the stand rod; an end part of the stand rod is provided with the trigone rotating body; the convex mirror, the flat mirror and the concave mirror are respectively mounted on the three side faces of the trigone rota...
The typical shape of Neoclassical antique picture frames is the Cassetta flat structure. On the contrary, Empire models have a deep concave surface to form their profiles. To synthesize, curved moldings are the main elements of Empire profiles, while flat lacquered surfaces determine Neoclassical fram...
英文: An imagery system consists with projector, concave conical mirror and convex conicai mirror and screen; the picture can be imagery distortion.中文: 由投影机,凹锥面反射镜和凸锥面反射镜与屏幕组成成像系统,将物失真成像。
However, unlike a grid, the edges of the light pattern projected by a snoot will have a hard edge. Uses for snoots mirror uses for grids, with the the hard edge being the main differentiator. 9. Flag/Gobo & Cuculoris/Cookie A flag (or gobo) is simply a device (typically black) ...
They start walking up the passageway, and at the end of the path is a concave structure, and in the center of it is an old NASA probe from three centuries earlier. Kirk rubs away the soot on the nameplate and makes out the letters "V G E R". He continues to rub and discovers ...
The prisms 23 and 24 may be cemented to the field lenses 29 and 30 which convert the virtual filter image of the original film 20 into the plane of the concave mirror 25 and this plane into the filter position of the copy film 31 required for exhibition. In order to render possible at...

case where a light is applied from a direction that is in parallel with the fibrous direction. As shown in FIG. 10, in the case where a light is made incident in the same direction as the fibrous direction, the shadows produced by the concave and convex portions of the fibers become ...
SOLUTION: Each PS composition element 10 corresponding to each concave mirror 6 provided in every light source 5 comes into contact with an adjacent PS composition element, and the S polarized light component of incident light is reflected in a direction where it is separated from an optical ...
The frame base structure 1 includes a perimeter and a recessed solid back integral with the perimeter. On the inner surface of the perimeter is the lens locking groove 12, which has an arcuate, concave cross-sectional shape. On the front surface of the solid back adjacent to the perimeter ...
