Appeal 2007-1170
Application 10/971,698
9. The claimed container, 30, holds a charge of solid organic material,
Alq (in embodiments, an organoaluminum chelate). (Specification
at 13:4-7.)
10. The container 30 is covered by a heater 40, which has a number of
apertures 42. (Specification at 13:22.)
11. The heater vaporizes the charge of organic material, forming a
cloud, VC, at a pressure Pv greater than the pressure of the evacuated
chamber, Pc. (Specification at 25:28 to 26:3.)
12. A solid baffle 50 is interposed between the charge of organic material
Alq and the apertures 42 at a selecting spacing, BHS. (Specification
at 13:11–14.)
13. According to the specification, the baffle 50 provides:
uniform conductance or, in other words, normalization of the
vapor flow out of the efflux apertures 42 of the vaporization
heater 40. The size and spacing of baffle member 50 with
respect to the heater cover surface and apertures 42 creates a
tortuous path of conductance or vapor flow between efflux
apertures 42 and solid material 13, causing vapor rising from
the heated solid material below to flow around the edges of the
rectangular baffle member before reaching the apertures and
escaping therefrom.
(Specification at 13:2–32.)
14. In particular, the Specification teaches that the baffle is positioned so
"[t]he spacing between the baffle and heater cover is made small enough that
a preponderance of the enclosed interior volume of the container * * * lies
below the baffle." (Specification at 13:32 to 14:3.)
