of structural members, to simplify the assembly adjustment, and
to decrease the weight of the overall device, as well as to
prevent slippage due to slack of the drive belt. As shown in
figure 2, linear motor 20 is installed horizontally on the car 1,
where upper rope 10a is positioned (page 6).
From the disclosure of Yoshinobu, we find that Yoshinobu
replaces the motor located on top of the car with a linear motor
mounted in the rope area. Turning to Aulanko, we make reference
to our findings, supra, as to the teachings and suggestions of
the reference. We additionally find from our review of Aulanko
(col. 1, lines 24-26) that a previously known technique was to
use a linear motor as the hoisting motor. Aulanko discloses
(col. 2, lines 29-32) that “[a]s compared to a linear motor, the
motor of the invention, when used as an elevator motor, provides
the advantage that it makes it unnecessary to build a rotor or
stator extending over the whole length of the elevator shaft.”
As we stated, supra, although Aulanko is directed to the motor
for hoisting the elevator, from the disclosure of Aulanko that
“[a]s compared with motors constructed according to previously
known technology, the elevator machinery (and motor) of the
invention is very flat. It can therefore be installed in many
places in an elevator system where previously known motors are
