Abstract: The control system is constructed so that an inverter output frequency command is increased/decreased based on a frequency-to-time rate-of-change command, and the frequency-to-time rate-of-change command is controlled with a current control system. Further, it is also constructed so that the frequency-to-time rate-of-change command is adjusted and the current command is changed with a readhesion control system. The control system is capable of accelerating and decelerating the vehicle with a torque corresponding to an inverter output current command which is generated basically without using any rotational frequency of induction motor, and further capable of accelerating and decelerating the vehicle with a torque corresponding to a value near the limit adhesion between the wheel and the rail under a condition of occurrence of slip/skid.

Abstract: In a refrigerating cycle in which a constant speed type compressor, an indoor heat exchanger and an outdoor heat exchanger are connected one by one by means of piping, a receiver is provided between the indoor and outdoor heat exchangers, and no capacity control mechanism is provided for the compressor, a gas-liquid flow rate regulating device is associated with the receiver for regulating at least either of liquid flow rate and gas flow rate of a cooling fluid which flows into and out of the receiver. This causes a quantity of excess refrigerant stored in the receiver to change to thereby vary an effective quantity of refrigerant circulating through the refrigerating cycle.

Abstract: A congestion control unit and method in an ATM network is disclosed. The congestion control unit includes a congestion detector, a congestion controller and a routing controller. The congestion detector receives the measured number of cells generated from an output link through an ATM switch module, transmits the measured number of cells to an adaptive connection admission control unit, and detects the state of the output link by use of a utilization of a cell transmission link. The congestion controller receives congestion state information from the congestion detector and receives a cell loss ratio through the ATM switch module. The congestion controller transmits a backward resource management cell to a user or generates a routing control request signal so as to assign the load of the input traffic to another affordable link, and supplies a monitor parameter to the ATM switch module.
