Appeal No. 2006-0965
Application No. 10/827,051
BACKGROUND
The appellants’ invention relates to a clamping device that may be specially
adapted for use in sealing together the components of mass flow controllers such as
those used in the manufacture of semiconductor devices (Spec. p.3). An
understanding of the invention can be derived from a reading of exemplary claim
24, which is reproduced below.

a surface across from said biasing device along said axis and configured to
oppose said compression force; and
a plurality of stoppers switchably exclusively interposed between said surface
and said biasing device along said axis.
