Appeal No. 1999-1937
Application No. 08/470,122
Representative independent claim 1 is reproduced as follows:
1. A motor operation controller comprising:
a converter section having a rectifier for converting a first AC voltage of a
power supply into a first DC voltage during a power mode,
an insulation type bidirectional DC voltage converter for converting said first
DC voltage into a second DC voltage during the power mode, and
an inverter section for converting said second DC voltage into a second AC
voltage and supplying said second AC voltage to a motor during the power
mode.
The examiner relies on the following references:
Dishner 4,743,812 May 10, 1988
DeDoncker et al. (DeDoncker) 5,027,264 Jun. 25, 1991
Claims 1, 2, 14 and 22-24 stand rejected under 35 U.S.C. § 103 as unpatentable
over DeDoncker and Dishner.
Reference is made to the briefs and answer for the respective positions of
appellants and the examiner.
OPINION
The examiner alleges that Dishner discloses the use of a bidirectional “voltage
converter in a conversion system involving several conversions involving AC/DC, DC/DC,
DC/AC” and that DeDoncker discloses “an insulation type bidirectional DC/DC
