Title: Rotational direction detector
Inventor: OOKUBO ATSUSHI
IPC: G01P13/04
Filed: 1977-12-16
Abstract: PURPOSE: To make it possible to detect the rotational direction of a rotary body, while reducing the cost, with the use of a simple construction by using a rotational direction detecting generator which is operative to generate such an AC voltage having symmetrical waveforms as has its positive and negative peak values reversed in accordance with the rotational direction of the rotary body.  
     CONSTITUTION: The output terminals X and Y of asymmetric waveform generator 10 of rotary magnet type are connected in parallel with positive and negative voltage detecting circuits 16 and 22, which are composed of a diode and a charging capacitor. A comparing amplifier 24 compares the respective output voltages of the  detecting circuits 16 and 22 to generate compared output signals. In case, for instance, the rotary magnet 28 of the asymmetrical waveform generator 10 is turned  in the direction of arrow A, positive and negative voltages are alternately generated  at the output terminal X and Y of the generator 10. However, a negative output  voltage is generated between the output terminals Z-Y of the comparing amplifier  24. In case the rotary magnet 28 is turned in the direction of arrow B, a positive  output voltage is generated at the output terminal of the amplifier 24 to make it  possible to detect that the rotational direction is reversed.

Title: Workpiece discriminating method and device therefor
Inventor: SAWARA YOSHIO
IPC: B07C5/10
Filed: 1991-06-21
Abstract: PURPOSE:To improve workpiece discrimination accuracy and reduce processing load by discriminating the directionality, mirror-image and front/rear face of a workpiece at need in addition to the discrimination of workpiece classification. CONSTITUTION:After obtaining the characteristic value required to discriminate the classification, direction, mirror-image and front/rear face of a workpiece and the reference value for discrimination, the silhouette image and reflected image of the discrimination object workpiece are taken in by an image detecting part 1. A workpiece classification discriminating part 5 then discriminates the classification of the object workpiece on the basis of the taken-in silhouette image and the characteristic value selected by a workpiece classification discriminating characteristic value selecting part 2 and also the upper and lower limit threshold value. In case the accuracy of discrimination performed only by the workpiece classification discriminating part 5 is insufficient, the object workpiece directionality discrimination performed by a workpiece directionality discriminating part 6, the object workpiece mirror-image discrimination performed by a workpiece mirror-image discriminating part 7, and the object workpiece top/ back face discrimination performed by a workpiece front/rear face discriminating part 8 are performed as occasion demands.

Title: Input control system
Inventor: TAKADA YUJI
IPC: G06Q40/02
Filed: 1987-06-17
Abstract: PURPOSE:To realize the input control with its high reliability by validating the input operation of each input operation part and setting each input operation part under an input enable state as soon as a transaction is finished. CONSTITUTION:The input operation of an input operation part that is operated first is validated at every input processing part among those input operation parts kept under the input enable states. At every input processing part including an input operation part where an input operation is carried out, the input operation of the input operation part excluding the validated input operation parts is invalidated. Then the input processing part carries out the prescribed processing for the input operation part whose input operation is validated. When said processing is finished, the valid and invalid states are released for all input operation parts corresponding to the input processing parts. Thus it is possible to ensure the input control with its high reliability.

IPC: G06K9/62
Filed: 1981-09-24
Abstract: PURPOSE:To relieve erroneous recognition of a character deformed greatly by adding rescanning indication information corresponding to said character. CONSTITUTION:A character to be recognized has features extracted by a feature extraction part 2. A recognition processing part 4 collates the extracted features with individual feature information read out of a dictionary memory 3 successively.
