Claim Rejections - 35 USC § 103
4. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
5. Claims 1, 3-4, 7-8, 12-17 are rejected under 35 U.S.C. 103 as being unpatentable over USPN 9,787,246 to Tsumura, and in view of USPN 7,912,530 to Seki.
As to claim 1, Tsumura teaches a power converting apparatus (col. 2: lines 31 – col. 3: lines 20) comprising: a rectifier unit (fig. 1: “11”) rectifying first alternating-current power supplied from a commercial power supply(fig. 1: “3”); a capacitor (fig. 1: “15”) connected to an output end of the rectifier unit(fig. 1: “11”); an inverter (fig. 1: “17 ”) connected across the capacitor(fig. 1: “15”), the inverter(fig. 1: “3”) generating second alternating-current power and outputting the second alternating-current power to a motor(fig. 1: “81”); a detecting unit (fig. 1: “43”) detecting a first direct-current bus voltage(col. 6: lines 15-17), the first direct-current bus voltage being a voltage across the capacitor(col. 6: lines 23-26), and the control unit (fig. 1: “53”) controlling an operation of the inverter and the motor by using a second direct-current bus voltage(col. 6: lines 46-48), the second direct-current bus voltage being the first direct-current bus voltage after passing through the specific frequency bandpass unit(col. 6: lines 53-67 wherein the DC bus voltage is obtained after the current passes through the smoothing capacitor “15”).
Tsumura does not teach a control unit including a specific frequency bandpass unit passing a defined frequency band among power-supply pulsatile components contained in the first direct-current bus voltage wherein in a case where the commercial power supply is a single-phase commercial power supply, the control unit sets a control band of the specific frequency bandpass unit to be twice or lower than a frequency of the single-phase commercial power supply, and attenuates a second-order or lower component of the frequency of the single-phase commercial power supply at a rate of −40 dB/decade or more.
Seki teaches a control unit including a specific frequency bandpass unit (col. 10: lines 53 “bandpass filter”) passing a defined frequency band among power-supply pulsatile components contained in the first direct-current bus voltage wherein in a case where the commercial power supply is a single-phase commercial power supply, the control unit sets a control band of the specific frequency bandpass unit to be twice or lower than a frequency of the single-phase commercial power supply, and attenuates a second-order or lower component of the frequency of the single-phase commercial power supply at a rate of −40 dB/decade or more(col. 10: lines 53 – 62, col. 11: lines 33-45 wherein apparatus and method are taught to filter the commercial power supply in a wide range of frequencies including but not limiting to -40 dB/decade or more).
Thus, it would have been obvious to one of ordinary skill in the art before the
effective filing date of the claimed invention to implement the teachings of Seki into Tsumura since Tsumura suggests a motive power system and Seki suggests the beneficial use of power filtering technique in the analogous art of power control technology.
The motivation for this comes from the fact that Seki teaches the power filtering technique which can be used to improve the motive power system disclosed by Tsumura.
As to claim 3, Tsumura teaches a power converting apparatus (col. 2: lines 31 – col. 3: lines 20) comprising: a rectifier unit (fig. 1: “11”) rectifying first alternating-current power supplied from a commercial power supply (fig. 1: “3”); a capacitor (fig. 1: “15”) connected to an output end of the rectifier unit(fig. 1: “11”); an inverter (fig. 1: “17 ”) connected across the capacitor(fig. 1: “15”), the inverter(fig. 1: “3”) generating second alternating-current power and outputting the second alternating-current power to a motor(fig. 1: “81”); a detecting unit (fig. 1: “43”) detecting a first direct-current bus voltage(col. 6: lines 15-17), the first direct-current bus voltage being a voltage across the capacitor(col. 6: lines 23-26); and, the second direct-current bus voltage being the first direct-current bus voltage after passing through the specific frequency bandpass unit (col. 6: lines 53-67 wherein the DC bus voltage is obtained after the current passes through the smoothing capacitor “15”).
Tsumura does not teach a control unit including a specific frequency bandpass unit passing a defined frequency band among power-supply pulsatile components contained in the first direct-current bus voltage, the control unit controlling an operation of the inverter and the motor by using a second direct-current bus voltage wherein in a case where the commercial power supply is a three-phase commercial power supply, the control unit sets a control band of the specific frequency bandpass unit to be six times or lower than a frequency of the three-phase commercial power supply, and attenuates a six-order or lower component of the frequency of the three-phase commercial power supply at a rate of −40 dB/decade or more.
Seki teaches a control unit including a specific frequency bandpass unit passing a defined frequency band among power-supply pulsatile components contained in the first direct-current bus voltage, the control unit controlling an operation of the inverter and the motor by using a second direct-current bus voltage wherein in a case where the commercial power supply is a three-phase commercial power supply, the control unit sets a control band of the specific frequency bandpass unit to be six times or lower than a frequency of the three-phase commercial power supply, and attenuates a six-order or lower component of the frequency of the three-phase commercial power supply at a rate of −40 dB/decade or more (col. 10: lines 53 – 62, col. 11: lines 33-45 wherein apparatus and method are taught to filter the commercial power supply in a wide range of frequencies including but not limiting to -40 dB/decade or more).
Thus, it would have been obvious to one of ordinary skill in the art before the
effective filing date of the claimed invention to implement the teachings of Seki into Tsumura since Tsumura suggests a motive power system and Seki suggests the beneficial use of power filtering technique in the analogous art of power control technology.
The motivation for this comes from the fact that Seki teaches the power filtering technique which can be used to improve the motive power system disclosed by Tsumura.
As to claim 4, Tsumura teaches a power converting apparatus comprising:
a rectifier unit (fig. 1: “11”) rectifying first alternating-current power supplied from a commercial power supply (fig. 1: “3”); a capacitor (fig. 1: “15”) connected to an output end of the rectifier unit (fig. 1: “11”); an inverter (fig. 1: “17 ”) connected across the capacitor (fig. 1: “15”), the inverter (fig. 1: “3”) generating second alternating-current power and outputting the second alternating-current power to a motor (fig. 1: “81”); a detecting unit (fig. 1: “43”) detecting a first direct-current bus voltage (col. 6: lines 15-17), the first direct-current bus voltage being a voltage across the capacitor (col. 6: lines 23-26), the control unit (fig. 1: “53”) controlling an operation of the inverter and the motor by using a second direct-current bus voltage (col. 6: lines 46-48), the second direct-current bus voltage being the first direct-current bus voltage after passing through the specific frequency bandpass unit (col. 6: lines 53-67 wherein the DC bus voltage is obtained after the current passes through the smoothing capacitor “15”) and a booster unit (fig. 1: “51”) boosting a voltage of direct-current power output from the rectifier unit(fig. 1: “11”).
Tsumura does not teach a control unit including a specific frequency bandpass unit passing a defined frequency band among power-supply pulsatile components contained in the first direct-current bus voltage in a case where the commercial power supply is a single-phase commercial power supply, the control unit sets a control band of the specific frequency bandpass unit to be twice or lower than a frequency of the single-phase commercial power supply, and attenuates a 2 n-th order component of the frequency of the single-phase commercial power supply at a rate of −40 dB/decade or more, where n is an integer of two or more, and controls an operation of the booster unit by using the second direct-current bus voltage.
Seki teaches a control unit including a specific frequency bandpass unit (col. 10: lines 53 “bandpass filter”) passing a defined frequency band among power-supply pulsatile components contained in the first direct-current bus voltage in a case where the commercial power supply is a single-phase commercial power supply, the control unit sets a control band of the specific frequency bandpass unit to be twice or lower than a frequency of the single-phase commercial power supply, and attenuates a 2 n-th order component of the frequency of the single-phase commercial power supply at a rate of −40 dB/decade or more, where n is an integer of two or more, and controls an operation of the booster unit by using the second direct-current bus voltage (col. 10: lines 53 – 62, col. 11: lines 33-45 wherein apparatus and method are taught to filter the commercial power supply in a wide range of frequencies including but not limiting to -40 dB/decade or more).
Thus, it would have been obvious to one of ordinary skill in the art before the
effective filing date of the claimed invention to implement the teachings of Seki into Tsumura since Tsumura suggests a motive power system and Seki suggests the beneficial use of power filtering technique in the analogous art of power control technology.
The motivation for this comes from the fact that Seki teaches the power filtering technique which can be used to improve the motive power system disclosed by Tsumura.
