Appeal 2007-0022
Application 10/148,935
7. Accordingly, Rabenhorst appears to disclose in Figure 6 a flywheel
rotor comprising anisotropic elements wound about the hub, as in Figure 1.
8. Rabenhorst shows in Figure 7 another embodiment having a flywheel
rotor 130, which appears from the cross hatching to be made from a plurality of
metal discs, and a shaft 126 extending through a central aperture 128 of the rotor
130 (Rabenhorst, Figure 7 and col. 6, ll. 1-6). Rabenhorst provides no disclosure
as to the specific metal used or the method of construction of rotor 130.
9. Rabenhorst fails to teach or suggest a “flywheel cylinder with a
plurality of steel discs connected together, said discs being free of axial through
holes.”
10. The Examiner admits that Hoshino “fails to show the flywheel
cylinder with a plurality of steel discs connected together” (Answer 4).
11. The Examiner relies on Cachat only for the teaching of “a process of
producing a flywheel comprising steps of quenching and tempering the flywheel”
(Answer 8).
12. Cachat does not teach or suggest a “flywheel cylinder with a plurality
of steel discs connected together.”
13. The Examiner found that it would have been obvious to modify the
discs of Nakayama with the hole-less discs as taught by Rabenhorst “to provide a
more balanced flywheel system so that less vibration can be experienced thus
creating a more effective energy storage system” (Answer 6, 8).
14. The Examiner based this finding of motivation to combine on an
alleged teaching in Rabenhorst of using hole-less discs to provide a more balanced
