摘要： A speed region of a motor is divided into a region lower than a first switch speed VS1, a region higher than a second switch speed VS2 and a region between the first and second switch speeds. An abnormal load determination level to be compared with an estimated load obtained by an observer is set for each of the regions. An abnormal load determination level AL4 applied when an acceleration exceeds a threshold value is set. The abnormal load determination level AL4 is used for comparison with the estimated load until a predetermined period of time elapses after the acceleration to be commanded to the motor, which once exceeded the threshold level, drops. In other cases, the estimated load is compared with the abnormal load determination level having a value according to the speed. If the estimated load exceeds the compared abnormal load determination level, it is judged that a collision is detected.

摘要： A controller for a die cushion mechanism includes: a spring element that is displaced according to force between the die cushion mechanism and a slide; a force instructor that instructs force; a force detector that detects force; and a speed instruction generator that generates a speed instruction of the servo motor, based on a force instruction value instructed by the force instructor and a force detection value detected by the force detector. The speed instruction generator generates the speed instruction by multiplying a force gain by a force difference determined from a difference between the force instruction value and the force detection value. The speed instruction generator changes the force gain, based on a spring constant corresponding value of the spring element determined from a force indicator that works between the slide and the die cushion.

摘要： Phosphor layers (110G, 110B, and 110R) are made of a combination of: blue and green phosphors that are positively charged on their surfaces and baked in an oxygen-nitrogen atmosphere to reduce oxygen vacancy, and that have a β-alumina crystal structure; and a red phosphor made of an yttrium oxide compound. Uniformly forming such phosphor layers on the wall surfaces of barrier ribs (109) provides equal charge characteristics of the phosphors of respective colors, reduces oxygen vacancy in the phosphors, and inhibits adsorption of various gases in the panel production process. This can stabilize the discharge characteristics and prevent luminance degradation at driving the panel.

摘要： A device for controlling a die cushion mechanism including a servo-motor as a drive source and producing a force adapted to be applied to a slide in a press machine. The device includes a section for commanding a force to be produced by the die cushion mechanism; a section for detecting a force produced by the die cushion mechanism and applied to the slide; a section for detecting a moving speed of the slide; and a section for executing a force control on the servo-motor. The force controlling section executes force controls in mutually different modes on the servo-motor, through mutually different control loops, one mode being provided for an initial stage defined from an instant when the die cushion mechanism starts producing the force to be applied to the slide until a predetermined subsequent instant, and another mode being provided for a succeeding stage defined after the predetermined subsequent instant, by using at least a slide-speed detected value detected by the slide-speed detecting section. The force controlling section includes a section for preparing a first speed-command value to be commanded to the servo-motor in the initial stage and a second speed-command value, different from the first speed-command value, to be commanded to the servo-motor in the succeeding stage.
