Abstract
PURPOSE:To improve the resolution of an equipment that uses a precise slit, by separately adjusting width, position and slope of the slit and eliminating their mutual effect. CONSTITUTION:A flange 1, tubes 2, 3 and a shaft 4 are constructed as an integral unit by air tightly vacuum welding bellows 8, 9 and 10 to between the flange, tubes and the shaft. To an end of the tube 2 a bellows 11 is fixed by a screw. A protrusive round part of the bellows 11 is insertion fitted to a round hole of a slit holder 12, and the slit holder 12 is rotated for the bellows 11. A slit guide 13, spring 14 and a slit 15 are built in to the slit holder 12 in such a manner that the center of the slit is aligned to the center of the hole. The slit 15 is movably arranged only in the direction of width of the slit by the slit guide 13, and the operation of open-close of the slit can be performed by a wedge at the point end of the shaft 4.
