device. However, the issue is what Martin teaches in the
situation where the power supply fails. As discussed above,
Martin teaches that when the power supply fails, the horizontal
deflection control circuit 36 provides protection by causing the
voltage to transistor 58 to decay off at a slow enough rate to so
that transistor 58 will be turned on to cause the beam to be
horizontally deflected off the screen.
From all of the above, we find that the prior art suggests
the invention set forth in appellant's claim 1, and that
appellant has not successfully rebutted the prima facie case of
obviousness. Accordingly, the rejection of claim 1 under 35
U.S.C. § 103(a) is affirmed. Claims 2-11 fall with claim 1.
Accordingly, the rejection of claims 1-11 under 35 U.S.C.
§ 103(a) is affirmed.
