Abstract: PURPOSE:To improve the accuracy of speed detection at a very low speed and to minimize the time lag in the stage of speed detection by detecting the power generation output of different phases induced in >=2 phases of secondary windings as an analog speed component. CONSTITUTION:The outputs 5A, 6A of the secondary windings 5, 6 of a resolver RS detect the speed components from the 1st and 2nd detectors 9, 10 and output signals 9A, 10A in a rotating electric machine for position detection which detects an angular displacement theta from the change in the electromagnetic coupling condition of both windings by rotating relatively one or polyphases or primary windings and >=2 phases of secondary windings. The position components are detected by the detectors 9, 10 from the outputs 5A, 6A of te windings 5, 6 and signals 9B, 10B are outputted. These outputs are inputted to a synthesizing circuit 11 by which the outputs are subjected to multiplication and addition. The signal 11A proportional to the rotating speed of the resolver RS is detected as the analog signal of the speed component. The error and time lag to be generated in the digital processing stage are therefore eliminated and the speed detection with high accuracy is made possible.

IPC: G06F17/21
Filed: 1986-07-08
Abstract: PURPOSE:To make it possible to make unification by preparing a document according to warning by sending out a warning when an operator inputted the same word in different writing. CONSTITUTION:When a character string of mixed KANJI (Chinese character) and KANA (Japanese syllabary) is inputted from an inputting section 11, a word detecting section 12 analyzes the character string, and detects whether a word for which both writing in KANJI and writing in HIRAGANA (square form of KANA) are allowable exists in the character string. A word table 13 is used as data for this analysis. When relevant word exists as the result of this inspection, a comparator section 15 operates and it is examined by retrieving a temporary buffer 14 whether a homonym with the word to be inputted was inputted previously or not. When the same word is retrieved, the comparator section 15 compares whether the way of writing of the word to be inputted and the way of writing of the word used previously are the same or not. When the writing is different, an operator is requested to correct or confirm by outputting the fact to a display section 17 or by sending out alarm sound.
