The objective system for use on a single objective type binocular stereomicroscope comprises an objective lens for converting light from an object into an afocal light flux and two viewing optical units for receiving light emanating from the objective lens to form left and right images, which satisfies condition: 1.0<FL/L<1.6 where FL is a focal length of the objective system, and L is a distance from a first lens surface of the objective system on an image point side to a sample surface.

Abstract: A moving vehicle specification system having an auxiliary specification function. If a vehicle could not be specified by a local controller, the license plate number is decoded from a license plate image in a method where a number database is referenced according to grouped information and number information is retrieved. Auxiliary specification of the vehicle is performed through a comparison between the searched result and the decoded result. This prevents any impairment in the real-time performance of the processing based on local controller and permits more accurate vehicle specification.

Then, a liquid amount of a first liquid-operated cylinder is varied by fore and aft slider movement, and a liquid amount of a second liquid-operated cylinder is varied by the left right slider movement. Accordingly, the micromanipulator is finely moved in the same direction as the mouse is moved.
