Title: Elevator motor drive system
Inventor: OSHIMA KENJI
IPC: B66B1/30
Filed: 1999-09-08
Granted: 2002-04-11
Abstract: The present invention relates to an elevator motor drive system, wherein a multiple-wound, three-phase, variable speed motor having N independent winding sets is driven by N inverters, each responding to 1/N of the torque and excitation current commands, and the torque current is limited as a function of N times the limiting current each inverter may tolerate, when all inverters are functioning. When M inverters fail, they are disconnected from the motor, the torque current is limited as function of N-M times the limiting current each inverter may tolerate. The remaining N-M inverters may each respond to 1/(N-M) of the torque and excitation commands. The excitation current may be maximized as (N-M) times the limiting current divided by the square root of two. The speed command may be predetermined by the integration over an acceleration interval, of the maximum acceleration achievable with torque available from those of the inverters which have not failed, in view of the inverters' current limits.

IPC: G05B19/404
Filed: 1997-04-22
Granted: 2001-12-21
Abstract: An alignment correction method which can obtain proper correction values and a semiconductor device fabricated through this alignment method are obtained. An alignment correction part (6a) calculates a stepper correction value which is set in a stepper (4a) in next alignment from trends of true shift amounts obtained from a plurality of types processes. The true shift amount, which is the difference between stepper correction value set in the stepper and overlay check correction values detected by overlay checking devices, is actual shift amount upon alignment. The number of the true shift amounts obtained from the plurality of types of processes is larger than that of true shift amounts obtained from a single process. Thus, a trend of the true shift amounts is proper, whereby a correction value set in the stepper for the next alignment becomes proper.
