Indexing Slide Mechanism for Metal Thickness Monitoring in an Evaporator
The mechanism presented accurately records individual film thicknesses in a
multilayer evaporation process.
Referring to the drawing, a movable glass slide is placed under a mask. A
slot in the mask allows evaporant to collect on the slide. When the slide is
moved to a new location, a new part of the slide is exposed to the evaporant.
There is a large window in the mask so that the composite film thickness can be
The slide is indexed in the following manner. A gas piston moves a pawl
which turns a ratchet. The ratchet is on the same shaft as a spur gear which
moves a rack. The slide is carried on the rack with the slide being repeatedly
positioned by a ball plunger which falls into detent holes in the slide carrier.
Motion of the slide is reversed for resetting by raising the pawl with a cam.
