Title: Recognizing device for basic period
Inventor: FUKUMA KOJI
IPC: G10L19/00
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To recognize a high speed and highly accurate basic period with a method in which multiplication processing is eliminated as much as possible and addition processing is mainly used by eliminating average period components and outputting a period eliminated the last time as the basic period when it is judged that a signal level is made zero. SOLUTION: Average period components obtained from a wave number discriminating section 6 counting the number of waveforms of signal data and an average period calculating section 7 are eliminated one by one by a filter section 5. And when it is judged by a signal level discriminating section 4 that a signal level is made almost zero, a period eliminated at the last time is outputted as the basic period. For filter processing, a system in which addition processing of simple integers such as a movement averaging method is mainly used. Also, in order to decide a period to be eliminated and the basic period, an average period is calculated from the number of vertexes of a waveform of signal data and a position in the direction of a time base.  This method is a system in which comparison processing are mainly used, and the number of times of multiplication/division processing requiring a much processing time is less.

Title: Identifying apparatus of direction of rotation
Inventor: IMAZEKI TAKASHI
IPC: G01P13/04
Filed: 1986-03-20
Abstract: PURPOSE:To prevent mistaken detection of a direction of rotation by a noise element, by judging the detected direction of rotation as correct when the rotating direction stays unchanged during at least one period of a pulse-series signal from an rpm-detecting means. CONSTITUTION:Pulse-series signals PG1, PG2 provided with a phase difference of 90 deg. are supplied to clock- and data-terminals of a D-FF4 respectively from pulse generators 2, 3 accompanying revolution of a motor 1. Consequently, the value 1 of the signal PG2 representing the leading point of the signal PG1 is latched from the output terminal (Q) of the FF4 to be issued out free-running counter 5 and memory 9 as an output signal S1. The counter 5 counts time from one change of the signal S1 to another and the counter 7 counts time of one period of the signal PG1. A comparator 8 gives an output instruction to a memory 9 only when time between changes of the signal S1 is longer than the one period portion of the signal PG1. Consequently, the memory 9 issues out the signal S1 as a direction of rotation identifying signal S2.
