Abstract: PURPOSE:To prevent the whole torque based on a wheel diameter difference from decreasing by increasing a motor current as a function of an inverter operating frequency or an electric rolling stock speed. CONSTITUTION:A current instruction generator 17 outputs a notch command and a current command IP responsive to a rotating speed fr. A high priority circuit 16 outputs the maximum current value IMmax of current detection values of current detectors 11, 12. A current controller 19 outputs a slip frequency correction value DELTAfS, a flip frequency correction value DELTAfS, and a motor speed fr are added or subtracted, and an inverter frequency fINV is output. A current instruction corrector 23 obtains a wheel diameter difference DELTAWD between a plurality of wheels at the time of idling, and obtains a correction coefficient (K) from the wheel diameter difference DELTAWD. Correction values of DELTAIP=Kfr in case of fr<=fr1 and DELTAIP=Kfr1 in case of fr>fr1 in term of set speed (fr1) are applied to the generator 17.

Title: Character recognition method
Inventor: RIYUU GAKUHEI
IPC: G06K9/68
Filed: 1994-10-26
Abstract: PURPOSE: To improve the discrimination precision of similar characters by selectively using the feature values related to similar characters to perform matching again. CONSTITUTION: If similar characters exist in candidates of recognition processing based on the quasiphase structure analysis method in a step 103, the postprocessing of detailed discrimination of similar characters is performed in a step 104. In a stage 1, only feature values whose degree of contribution to discrimination of similar characters is high among geometrical feature values used for detailed matching in the step 103 are used to perform matching. If the range of candidates cannot be narrowed down, one or plural new feature values corresponding to a similar character are obtained from the input character in a next stage 2, and this similar character is removed from candidates if these values are deviated from a corresponding range.
