Title: Control device for actuator
Inventor: MITSUNARI YUKIO
IPC: F15B11/08
Filed: 1994-12-28
Abstract: PURPOSE: To prevent accidental operation by providing an electromagnetic changeover valve and a resetting switch which is interlocked with OFF-operation of an emergency stopping switch in a pilot circuit, and disabling resetting operation in the case that a pilot valve is at a position except a neutral position. CONSTITUTION: When failure occurs during operation, an emergency stopping switch 23 is operated for stopping an actuator. Accompanied therewith, a resetting switch 27 is switched to a power source side contact position. An operation means of a pilot valve 11 is at a operation condition holding position, while a pressure switch 20 is switched to an ON state at a load pressure side contact. After solving the problem, it is impossible to reset the resetting switch 27 under this state. Current is carried to a coil of a relay 30 at this time, and the contact of the relay 30 is switched OFF, so that circuit lead to an electromagnetic changeover valve 8 is opened. Even when the emergency stopping switch 23 is operated, the electromagnetic changeover valve 8 is kept closed, so that the actuator is not operated.

Title: Paper sheets discriminating method
Inventor: SAKAI HIDETAKA
IPC: G07D7/06
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To improve the precision of high-speed discrimination by accurately calculating shift width at the time of input of paper sheets with a small arithmetic quantity. SOLUTION: When it is judged whether or not the paper sheet is genuine by comparing the detected waveform of a print pattern obtained by detecting a desired area of the paper sheet by a sensor with a reference waveform as the print pattern of a reference paper sheet, plural representative waveforms are generated by shifting detected waveform by varying the width of a shift from the reference waveform between possible maximum and minimum shift widths.  The differences between representative waveforms at plural predetermined places of a representative waveform and a reference waveform or the cumulative value of differences is calculated from the sum of absolute values or the sum of squares, and the shift width of the representative waveform having the largest difference value or the minimum cumulative values of the difference is used as shift width for the sensor detection of the detected paper sheet to correct the shift width in he process of paper sheets discrimination.

Title: Servo device
Inventor: IDEOKA YOSHIHIKO
IPC: G11B5/588
Filed: 1994-12-29
Abstract: PURPOSE: To precisely detect fluctuation in an average height position of a track by comparing the measuring value of this time with the measuring value of the last time and discriminating the fluctuation in the average height position of the track by the comparison result. CONSTITUTION: A relative speed between a drum motor 8 and a capstan motor 7 is adjusted so that when the measuring value Ts(u) is obtained, it is compared with a reference value To, and an error amount becomes error information, and the rotational speed of the capstan motor 7 is adjusted by that the error information is reflected to a drive current for the capstan motor 7, and an excellent tracking state is obtained. In such a timing ATF system servo operation, when the average height position of the track is fluctuated, normal operation becomes impossible. Thus, a motor servo circuit 12 continues the normal operation corresponding to the fluctuation in the average height position of the track also.
