Patent JP-H02133804-A (JP)
Title: Position controller
Inventor: NAGANO HIROYUKI
IPC: G05D3/12
Filed: 1988-11-15
Abstract: PURPOSE:To obtain a control system which can follow the position command value with high accuracy after the rise of an actuator and has the high stability by using a means which attenuates the DC component of a speed feedback signal. CONSTITUTION:A deviation counter 11 integrates the pulse train, i.e., the position command value outputted from a numerical controller and then operates the pulse train outputted from an encoder 24b to output the deviation between the position command value and the position measurement value. A speed controller 13 controls the speed of a motor 24 based on the output of a D/A converter 12. In this case, a DC cutting filter 14 functions to attenuate the DC component of the speed signal outputted from a tachogenerator 24a. As a result, the DC component of the speed feedback signal is attenuated. Then the deviation corresponding to the speed feedback signal is reduced after the rise of the motor 24. Thus an actuator position can be controlled with high accuracy.

Title: Document detector
Inventor: AISAKA SEIYA
IPC: G03G15/04
Filed: 1988-11-14
Abstract: PURPOSE:To detect document size automatically and to eliminate wasteful use of copying forms by monitoring the output of a document size detecting means continuously for a specific time even if a copy start switch is turned on before a document pressure mat is pressed. CONSTITUTION:A limit switch 3 which detects the opening/closing state of the document pressure mat, an optical document size detection sensor 7 which detects the size of a document on a document platen, a copy start switch on a console panel, etc., are connected to a control unit 9. If the copy start switch is turned on before the document pressure map is turned on, the sensitivity of the sensor 7 is lowered to reduce the influence of disturbing light and the size is detected for the specific time. The sensitivity of the sensor 7 is increased, for example, one second later and the document size is detected with high accuracy. Even if an operator presses the copy start switch before closing the document pressure mat, the document size is detected to eliminate such wasteful use that a copying form of improper size is used.
