COATER HARDWARE... (Cont'd)

The process requires the steps of heating one or more
material~containing crucibles simultaneously or in sequence
while moving at least one of said (a) crucibles or said (b)
receiving surfaces in a translational manner along parallel
planes with respect to each other.

The concept is exemplified in the device shown in the
Figure in which base member (15) and rails (13) as well as
a rotatable or rotating reciprocating spindle (8) are affixed

or conveniently mounted within a vacuum coater capable of
achieving an atmospheric pressure to about 5 x l0~~Torr in
general accordance with known coating procedures. Such
general procedures and vacuum coating technicrues are
described~ for instance

crucibles exemplified by (9) are subdivided by baffles or end
plates (12) for holding individual coating comp...
