Title: Phase modifier
Inventor: NAGAMURA HIDEHIRO
IPC: H02J3/18
Filed: 1991-08-02
Abstract: PURPOSE:To prevent lowering of efficiency due to power loss and to reduce installation space by eliminating the drive motor conventionally employed for starting a synchronous phase modifier. CONSTITUTION:When a power converter 11 produces AC three-phase power, a rotating field is induced in the primary windings 6a, 6b, 6c of an AC exciter to cause rotation of the rotary side, i.e., the secondary winding 3, of the AC exciter. Consequently, a synchronous phase modifier 1 coupled therewith is started. When the synchronous phase modifier 1 reaches a synchronous speed, a circuit breaker 10 is thrown in to conduct only semiconductor elements 8a, 8e, 8f and thereby DC power is outputted from the power converter 11. At that time a nonrotating field is induced in the primary windings 6a, 6b, 6c but since the secondary winding 3 is rotating, an AC voltage is produced and a field current flows through a rectifier 4 into the field winding 5. Consequently, the synchronous phase modifier 1 can feeds the system with reactive power.

IPC: G06F9/46
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the performance of an entire microprocessor even when the number of tasks to process is larger than the number of the register groups of microprocessors. SOLUTION: A saving/returning control circuit 12 in a multitask processor 30 saves a context loaded in one of the register groups 24-1 to 24-M in a memory for a context 14 through an internal bus for saving/returning 11 provided separately from an internal bus 17, and returns the context loaded in the context memory 14 back to the register group.
