ABSTRACT:
An improved manipulator for manipulating a glass electrode or the like is disclosed. The manipulator includes a driving section and an actuating section with the glass electrode mounted thereon both of which are in operative association with one another by way of three lines of tubes. The X-coordinate, Y-coordinate and Z-coordinate driving mechanisms in the driving section are hydraulically communicated with the X-coordinate, Y-coordinate and Z-coordinate displacing mechanisms in the actuating section. As a tiltable lever with the Z-coordinate driving mechanism incorporated therein is inclined, hydraulic pressure in the X-Y coordinate plane driving mechanism constituted by the combination of X-coordinate and Y-coordinate rectilinear driving mechanisms varies and thus developed pressure variations are transmitted to the X-coordinate and Y-coordinate displacing mechanisms in the actuating section whereby the glass electrode is displaced by a distance equivalent to an angle of inclining movement of the tiltable lever in both the directions of X-coordinate and Y-coordinate. Displacing of the glass electrode in the direction of Z-coordinate is effected by rotating the knob on the tiltable lever. Water having a thermal expansion coefficient smaller than oil is used as hydraulic medium for each of the hydraulic cylinders.
