Appeal No. 96-2661
Application 08/177,975
On page 11 of the brief, Appellants argue that
Teuling fails to teach a correction circuit means having a
maximum of
linearity error of a substantially constant value over a range
of deflection frequencies of 30 kHz to 60 kHz. We note Appel-
lants' claim 17 recites an "S-shape correction circuit means
providing a maximum of linearity error of a substantially
constant value of less than 5% over a predetermined range of
horizontal deflection frequencies of 30 kHz to 60 kHz."
On pages 3 and 4 of the Examiner's answer, the
Examiner states that Teuling teaches a picture display device
including an S-shape correction circuit wherein a control
circuit 17 and 18 adjusts a supply voltage controlling the
amplitude of the deflection current in accordance with a
detected horizontal deflection frequency, and a control cir-
cuit 16 generates a correction current in response to the
detected frequency wherein the deflection current and the
correction current flow through the S-capacitor 12 in opposite
directions. The first control circuit is adjusted such that
the amplitude of the deflection current is constant, while the
