Appeal No. 2006-0259
Application No. 09/220,462
disclosure, a general suggestion that in elevator machinery, the
motor used should be very flat, for use in places where
previously known motors are difficult or impossible to install,
without an increased space requirement. We observe from
appellants' specification (page 1, lines 13-15) that the top of
the elevator car is a place where space is at a premium.
Accordingly, we find that Aulanko would have suggested to an
artisan that the motor and pulley of Yoshikawa be replaced with a
flat motor that can be installed without an increased space
requirement, as taught by Aulanko.
In addition, from the disclosure of Aulanko (col. 2, lines
41-47 and) we find that:
The axial length of the motor of the invention is
very small. The small axial length also means that
the elevator machinery of the invention can be placed
in various locations in the elevator shaft, e.g. in
the place of a diverting pulley or in the bottom or
top part of the shaft, without increasing the shaft
dimensions from what they would be in any case.
In addition, from the disclosure of Aulanko (col. 4, lines 28-36)
we find that:
The rotor 17 is mounted on the motor shaft 13 by means of
a bearing 16. The rotor is a disc-shaped body placed
substantially at the middle of the shaft 13 in the
axial direction. The traction sheave 18 consists of
two ringlike halves 18a and 18b having the same
diameter and provided with rope grooves 19. The
halves 18a, 18b are placed on the rotor on opposite
sides in the axial direction, between the windings 20
