Application 08/351,064
DECISION ON APPEAL
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 40, 41, 43, and 55.
We affirm-in-part.
BACKGROUND
The invention is directed to a termination device for a
bus in which negligible current flows through the termination
device when no signal is transmitted via the bus.
Claim 40 is reproduced below.
40. An electronic system comprising:
a plurality of electronic circuits having a signal
input and output function and a push-pull type output
circuit;
a bus to which the plurality of electronic circuits
are connected; and
a termination device having a first non-linear
element, and a second non-linear element,
the first non-linear element being connected between
a termination voltage line and said bus in a forward
direction,
the second non-linear element being connected, in
the forward direction, between the bus and a voltage line
carrying a voltage lower than a termination voltage
supplied via the termination voltage line,
no current flowing in the bus when no signal is
transmitted via the bus.
