and
defection
is
performed
in
the
last
half
of
the
scanning
period.
Next,
when
Q432
becomes
OFF,
the
charge
that
had
been
stored
in
DY
up
to
that
point
releases
a
resonance
current
to
the
resonant
capacitors
C435,
C444
and
C445
and
charges
them.The
current
stored
in
C435,
C444
and
C445
is
then
flowed
back
to
DY,
and
an
opposite
charge
is
then
stored
in
DY.
This
opposite
charge
then
switches
the
dumper
diode
in
Q432
ON,
the
resonance
state
is
completed,
and
an
amplifying
current
is
then
flowed
again
directly
to
DY
through
the
dumper
diode.
By
this
means,
deflection
in
the
first
half
of
the
scanning
period
is
performed,
and
when
Q432
becomes
ON
at
the
end
of
the
first
half
of
the
scanning
period,
deflection
during
the
last
half
is
begun,
thus
completing
one
cycle.
