Abstract: There is provided a method for designing a corrugated Fermi antenna having a broad-band and circular directivity required for receiving an image by using a wave of millimeter order. As a first step, an inflection point of the Fermi-Dirac function as a taper function of the Fermi antenna is changed so as to set the beam width of plane H to a beam width having a target directivity. After the beam width of the plane H is set to the target value, the aperture width of the Fermi antenna is changed so as to set the beam width of the plane E to a beam width having a target directivity. Thus, by adjusting the beam width values of the planes H and E independently from each other and matching them with the target values, it is possible to design a Fermi-antenna having a broad-band and circular directivity in a short time.

Abstract: A motor driving apparatus capable of drivingly controlling a plurality of inverter units with a single motor driving command from a motor control unit, and thereby control a large-capacity motor or the like. The motor control unit sends out a single motor driving command (torque command) S. An intermediary unit obtains motor driving commands S×A1 to S×A4 for the inverter units by multiplying the motor driving command S by each of coefficients A1 to A4 set in advance. The inverter units are fed with the motor driving commands S×A1 to S×A4 individually and drive a single motor. Since the motor is driven by the total current supplied by the inverter units, the motor can generate a large torque. The motor control unit only needs to generate a single motor driving command S, and hence only needs to operate a single processing part. Hence, the motor control unit can generate and send out motor driving commands for other motors to drive them.
