Abstract: The excitation overcurrent detection unit for the doubly-fed electric machine is provided with a function to determine an excitation current magnitude relationship among three phases. The firing pulse is held to on-state or off-state to cause the largest-current phase and the second-largest-current phase to charge the DC capacitor by the operation of diodes. The conduction ratio of the third-largest-current phase or minimum current phase is controlled according to the detected current value to protect against a possible short-circuit across the DC capacitor. When the voltage of the DC capacitor exceeds a preset value, the voltage is suppressed by operating active or passive power devices.

Abstract: To reduce an uplink interference in a network with a first base station of a large output and a second base station of a small output. Detecting the interference, the second base station urges the first base station to hand over a terminal causing it to the second base station. Multiple base stations and one or more terminals exist in this system, each terminal connects with one base station, and a serving base station is changed according to a communication state of each terminal. If the different second base station other than the first base station to which the terminal connects detects a large interference, the second base station will multicast transmit information for urging handover to the base stations except itself. The base station having received the information specifies a terminal giving the interference to the second base station, and makes it to be handed over thereto.

Abstract: In an exemplary storage system, a processor assigns an unused process to a read request designating an area of a logical volume. The processor determines whether the data designated by the read request is in a cache memory, based on a first identifier for identifying the area designated by the read request. When the designated data is not in the cache memory and a part of physical volumes providing the logical volume is a first kind of physical volume, the processor stores the first identifier associated with an identifier for identifying an area allocated in the cache memory. When the designated data is not in the cache memory and a part of the physical volumes is a second kind of physical volume, the processor stores a second identifier for identifying the process assigned to the read request associated with an identifier for identifying an area allocated in the cache memory.
