Abstract: A hydraulically-operated micromanipulator apparatus is disclosed.

Abstract: A micromanipulator fine control apparatus is operated with a mouse. As the mouse is moved to the front, rear, left and right, a control handle is tilted to the front, rear, left and right, respectively, and a fore and aft fine control slider and a left-right fine control slider are moved in the corresponding directions. A liquid amount contained in a first liquid-operated cylinder is varied by a fore and aft fine control liquid-operated arrangement responsive to the fore and aft fine control slider, and a liquid amount of a second liquid-operated cylinder is varied by left-right fine control liquid-operated arrangement responsive to the left-right fine control slider. Accordingly, the micromanipulator is finely moved in the same direction as the mouse is moved.

Abstract: A micromanipulator apparatus includes an operation handle joined to a slide plate for moving the slide plate forward and backward and leftward and rightward. A first lever joined to the slide plate is rotated in forward and backward direction around a supporting point pin by means of a first guide pin engaged in a first slot in the slide plate, and a second lever is rotated in leftward and rightward direction around a second supporting pin by means of a second guide pin engaged in a second slot in the slide plate. Separate hydraulic devices are operated in response to activation by working rods associated with the respective levers. Movement of the slide plate and operation of the hydraulic devices provides precise movement to a workpiece supported by the apparatus.

Abstract: A micromanipulator fine control apparatus of the present invention is operated with a mouse. As the mouse is moved to the front, rear, left and right, a control handle is tilted to the front, rear, left and right, respectively, and a fore and aft fine control slider and a first left right fine control slider are moved in the respective directions. 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.

Abstract: A slide mechanism combined rough and fine adjustment in micromanipulator comprising an inside slider 30 provided with a rough adjustment female screw 30a in axial direction slidably fitted in recessed grooves 12a of a basic outside slider 12 in axial direction, a rough adjustment screw shaft 31 fitted into the rough adjustment female screw 30a of the inside slider 30, a fine adjustment inside slider 32 fixing the basic end part of the rough adjustment screw shaft 31 and provided with a fine adjustment female screw 32b, a rough adjustment bearing metal and concurrently fine adjustment outside slider 20 to fit and support the fine adjustment inside slider 32 non-rotatively but movably in axial direction in a through hole provided in axial direction, a fine adjustment screw shaft 33 to fit in the fine adjustment female screw 32b of the fine adjustment inside slider 32, an annular rough adjustment operation handle 23 to rotate the rough adjustment bearing metal and concurrently fine adjustment outside slider 20,
