It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.

The invention discloses a transformer operation control apparatus and method for suppressing magnetizing inrush current. A control portion 80 for a breaker 10 causes the breaker 10 to apply a current of a first apply phase (R phase) at a timing where a residual flux of R phase agrees with a steady magnetic flux. Thereafter, the control portion 80 determines whether or not the current measured by current measuring portions 40R, 40S, 40T exceeds a threshold value. When the measured current does not exceed the threshold value, the control portion 80 causes the breaker 10 to apply currents of the other two phases (S and T phases) at a timing where a voltage of R phase becomes zero. When the measured current exceeds the threshold value, the control portion 80 causes the breaker 10 to once shut off the current of R phase and to apply again the current of R phase.

The invention provides a sintered NdFeB rare-earth permanent magnet material with modified grain boundary phase and a preparation method thereof. The material refers to the R-Fe-M-B-based rare-earth permanent magnet of ROF compound with ordered fcc structure in the grain boundary phase, wherein R is one or more of rare earth element Nd, Pr, Dy, Tb and Y, and M is one or more of Al, Cu, Ga, Nb, Mg, Si and Mo elements. The major elements of the grain boundary phase are R, O and F elements, and the ratio of R to O and F is approximately equal to 1:1:1 (atomic percent). The preparation method is that the temperatures and cooling rates of sintering and second tempering are controlled to ensure that the F atoms in the added fluoride which can fuse with the grain boundary rich-R phase of the NdFeB magnet and the O atoms in the grain boundary phase can be in ordered arrangement to form an ordered fcc grain boundary phase. The ordered fcc grain boundary phase has better demagnetizing and coupling functions, thus facilitating to increase the coercive force of the magnet and furthest reducing the dosages of Dy and Tb.

A control unit 13 of an electric power supply system causes, responsive to a closing command signal phi B, a switch 2 corresponding to R phase to be thrown at a timing when a stationary magnetic flux and a residual magnetic flux of R phase are coincident with each other and then subsequently causes other switches 3, 4 corresponding to S phase and T phase to be thrown at a timing which is delayed from a zero point of an alternating voltage of R phase by a predetermined phase angle of 0-30 degrees, such that the difference of the stationary magnetic flux and the residual magnetic flux of each of S phase and T phase is minimum. Therefore, an exciting incoming current which flows into a three-phase transformer 8 at a time of throwing a three-phase breaker 1 provided with interpole capacitors 5-7 can be suppressed.
