    摘要: A control device for a press machine, by which one of the slide and the die cushion is suitably controlled, when a malfunction occurs in the other, such that the force between the slide and the die cushion does not excessively increase. The control device includes a slide control part for controlling the motion of the slide and a die cushion control part for controlling the motion of the die cushion. A first transmitter transmits an abnormal signal from the die cushion control part to the slide control part when a first detector detects a malfunction of the die cushion. The slide control part is configured to move the slide, when receiving the abnormal signal, such that the slide is away from the position of the die cushion at the time of receiving the abnormal signal by a certain distance and, to stop the slide.

    摘要: A servo motor for driving a die is provided with position and speed detectors. Further, a pressure sensor for detecting the pressure applied to a workpiece is provided. In the servo motor control unit, the smaller one of the speed command obtained by feedback control of the position and the speed command obtained by the pressure feedback control is selected as an output of a comparator. Based on the speed command output from the comparator, feedback control of the speed is performed and the servo motor is driven. In the state where the die does not press against the workpiece, a pressure error is large, the speed command by pressure control becomes large, and the speed command by position control becomes small. Therefore, position control is performed. When the workpiece is pressed, the position error increases, and the pressure error decreases, a speed command by pressure control is employed and pressure control is performed.

    摘要: The present invention aims to provide a method of producing a plasma display panel in which the fluorescent substance layer or the reflection layer is formed easily and accurately even for a minute cell structure, and in which the fluorescent substance layer or the reflection layer is formed evenly in the channels between the partition walls formed in stripes, or such a layer is formed also on the sides of the partition walls. To achieve this purpose, a fluorescent substance layer or a reflection layer is formed by applying a fluorescent substance ink or a reflection material ink continuously onto the channels, the ink being spouted out from a nozzle which runs along the partition walls. The nozzle may be directed to one side of the plurality of partition walls while running. Pressure may be put upon the ink having been applied onto the channels so that the ink sticks to both sides of the partition walls. The ink may be continuously spouted out from a nozzle while a bridge is formed between the nozzle and both sides of the partition walls by surface tension of the ink. A plate with a plurality of partition walls and channels in between may be formed so that adsorption of the sides of the channels against the ink is higher than that of the bottom of the channels.

    摘要: A disturbance load estimation method for a servomotor in which an disturbance load externally exerted on the servomotor can be accurately estimated even when the voltage is saturated. Actual values (Ir, Is, It) of three-phase alternating current determined by current loop processing (term 1) are converted by DQ conversion, and an effective current component (Iq) that contributes to a torque generated by the servomotor is obtained (term 4). Based on the obtained effective current component, a motor acceleration is estimated (term 5), a difference between the estimated acceleration and an actual motor acceleration (term 6) is obtained, and the disturbance load is estimated based on the acceleration difference (term 7).

    摘要: A current control method for a servo motor capable of compensating a delay in a current loop. A corrective electrical angle corresponding to the delay in the current loop is obtained and a phase angle is corrected using the corrective electrical angle. Then the delay of the current loop is compensated by a DQ coordinate conversion for converting a three-phase AC current into a two-phase DC current, or a two-phase DC voltage into a three-phase AC voltage, using the corrected phase angle. The phase angle is corrected by subtracting the corrective electrical angle from the phase angle and the DQ conversion is performed for obtaining a two-phase DC current from a three-phase AC current using the corrected phase angle. Alternatively, the phase angle is corrected by adding the corrective electrical angle to the phase angle and the DQ conversion is performed for obtaining a three-phase AC voltage from a two-phase AC voltage using the corrected phase angle, to compensate the delay of the current loop.
