Filed: 1980-06-12
Abstract: PURPOSE:To eliminate an error in operation through automating a change in manual numbering position, by printing a specific character corresponding to an unreadable character on a character read sheet, through a numbering controller. CONSTITUTION:When an indication signal, which indicates the existance of a character unreadable by a device OCR among characters entered in a character read OCR sheet 1, is transferred to a printing timing generator 9, the device 9 counts clock pulses generated by a sheet position detecting mechanism 8. Then, the device 9 prints a specific number at a numbering position P1 corresponding to the unreadable character, through a numbering controller 6. A signal transferred from a read head 2 is discriminated by a character reader 5 and when the character is recognized, another specific signal is not further printed at the position P1. Thus, a change in numbering position which is usually executed by an operater manually is automated to eliminate an error in operation.

Title: Method and device for angle detection
Inventor: TAKANO YOSHIYA
IPC: G01D5/249
Filed: 1987-04-03
Abstract: PURPOSE:To detect a smaller angle with an absolute value signal without making a sensor large by using the output signal of an increment type angle detector as an interpolating signal for the absolute value signal between measured values of an absolute type angle detector. CONSTITUTION:When the absolute type detector generates, for example, 30 binary-coded signals within a 360 deg. range, the value obtained by dividing 12 deg. by the number of increment signals is added as one interpolating signal unit to an absolute signal which indicates an initial position. When 360 increment signals are generated at equal intervals, there are 12 interpolating signals between binary-coded signals. When the detector stops at a position of 10 deg., the output of the absolute type detector is 1 and the increment type detector outputs 10 as a counted number. The detecting circuit is so constituted as to put two outputs together and recognize 1+10 as an angle of 10 deg.. Further, the increment signal can be converted into a smaller section signal by frequency division and even an angle smaller than 1deg can be detected.
