Title: High-speed current limiting and interrupting device for electric power system interconnection
Inventor: YAMAMURO KOZO
IPC: H01H33/59
Filed: 2002-03-08
Abstract: <P>PROBLEM TO BE SOLVED: To simplify circuit-breaker equipment for interconnection and reduce equipment expenses by improving a high-speed current limiting and interrupting device applied to an electric power system interconnecting system.  <P>SOLUTION: Separating circuit breakers are placed in an interconnecting bus 3 for interconnecting a commercial electric power system and distributed power supply units 2, and separates the distributed power supply units from the commercial system if an accident occurs in the system. As such a separating circuit breaker, a high-speed current limiting and interrupting device 9 is constituted by connecting a commutation circuit 15 and an arc extinguisher (nonlinear resistance element) 17 in parallel with a high-speed circuit breaker 11. The high-speed circuit breaker 11 performs contact parting operation when the breaker receives a signal from a fault detector 20. The commutation circuit 15 superposes high-frequency current on fault current during the contact parting operation of the high-speed circuit breaker to form a zero point. The arc extinguisher (nonlinear resistance element) 17 absorbs surge produced between the poles of the high-speed circuit breaker. An auxiliary circuit breaker (ordinary vacuum circuit breaker or switch) 26 is placed between the high-speed circuit breaker, and the commutation circuit and the arc extinguisher. After fault current is interrupted, the auxiliary circuit breaker is opened, and thereby the arc extinguisher is separated from the main circuit and protected. After the recovery of the system, synchronous power application is performed by the high-speed circuit breaker.  <P>COPYRIGHT: (C)2003,JPO

Title: Inverter for ac motor control
Inventor: MATSUBARA SHUNSUKE
IPC: H02P27/08
Filed: 2002-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an inverter for AC motor control from which necessity for gain unbalance adjustment at the time of operating the inverter and at the time of exchanging the inverter is eliminated.  <P>SOLUTION: Current detectors 4r and 4s and A/D converters 5r and 5s for detecting currents of 2 or above phases are incorporated and integrated in the inverter 10. A correction value for correcting gain unbalance is stored in EEPROM 7. A detection current value of an R phase is multiplied by the correction value, and gain unbalance is corrected. Current feedback gains in an R phase and an S phase are made equal. Since current detection means (4r, 4s, 5r and 5s) are incorporated in the inverter, gain unbalance is already decided and an information is stored in EEPROM 7. Consequently, the inverter can immediately be operated when the inverter is incorporated in the motor. Then, gain unbalance adjustment is not required at an incorporation site and site work becomes easy.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To reduce a difference in picture quality due to differences among the kinds of paper used by a plurality of image forming devices by correcting image data according to the difference in paper kind between an arbitrary image forming device (master machine) and another connected image forming device (slave machine).  <P>SOLUTION: In an image forming device system wherein the plurality of image forming devices are connected by a network, paper kind information on paper in a paper feed stage used by the master machine is transferred to the salve machine together with image data (step 21). The slave machine obtains the difference between the kind of paper used by the master machine and the kind of paper used by the slave machine and computes a correction value for the image data transferred from the master machine according to the difference between the kinds of paper (step 22). For example, paper for color print has a high white degree and normal paper is yellowish, so the slave machine which uses normal paper uniformly reduces yellow components of the image data by a certain quantity and prints an image based upon the corrected image data (step 23).  <P>COPYRIGHT: (C)2003,JPO

Thereby resistance is generated at an upper edge and a lower edge of the inserting hole 6, and the supporting rod 4 is fixed and the rotary shaft 3 at an upper end of the supporting rod 4 is also fixed. The upward force pushes a rear part of the roll cover 2 downward so as to touch against a roll using the rotary shaft 3 as a fulcrum. Thereby the roll cover 2 is fixed and a cutting line of the forefront edge is fixed. The upward force applies a downward force to a back side of the roll cover 2 by lever action so as to press the roll and stop, and the pulled-out paper is tensioned. The tensioned paper is touched against a cutting edge of the fixed roll cover 2, and the paper is cut.  <P>COPYRIGHT: (C)2003,JPO
