Appeal No. 1997-3253
Application 08/357,196
driving source when heated by heat radiated from the driving
source itself, the thermistors 17 and 18 could not achieve the
stated objective of rapid restarting of the motor after a
momentary stoppage. The heat radiated from the motor itself
would delay such restarting.
Turning to each of Appellants' independent claims, we
find that claim 1 recites
a thermistor means disposed in the vicinity of the
driving source for shutting off electricity to the
driving source as a result of heat generated by a
driving source locking current which flows through
the thermistor upon complete closure or complete
opening of the door glass, and for shutting off
electricity supplied to the driving source as a
result of heat generated by the driving source from
an overload condition.
Similarly, we find that Appellants' claim 6, which is the only
other independent claim, recites
a thermistor means disposed in the vicinity of the
driving source and electrically connected between
said driving source and source of electrical power
for shutting off said power to said driving source
when heated by a driving source locking current
which flows through the thermistor upon complete
closure or complete opening of the door glass, and
for shutting off electricity to said driving source
when heated by heat radiated from the driving source
itself as a result of an overload condition.
