摘要： A system has a screen module for displaying multicolor images on a screen having orderly-arrayed first, second, and third color LEDs, and a data-sending module sending control signals and image data to be displayed. The screen module has first, second, and third color gradation-control circuits for each pixel. The data-sending module comprises: a frame memory for temporarily storing image data; an image-data transfer controller for reading out image data from the memory and outputting it with a data-transfer clock; first, second, and third color pulse-train generators for generating high-speed pulse trains to be given to each gradation-control circuit; and a pulse-train outputting means for outputting the pulse trains for each color. Each pulse-train generator generates, with a constant period, pulse trains of 2n pieces or a number closely therebelow, pulse intervals varying with time according to a preset characteristic.

摘要： Disclosed herein is an electrorheological fluid damping control system. The suspension control system is comprised of a transformer and a rectifier circuit, which is electrically connected to a secondary winding of the transformer and is provided with capacitors. A capacitive load is electrically connected to output terminals of the rectifier circuit. When voltage to be applied across the capacitive load is cut off, electric charges stored in the capacitors and in a capacitive component of the capacitive load are discharged through a resistive component of the capacitive load. The capacitance of each capacitor is determined such that a discharge time constant of a circuit comprised of tile capacitors and the capacitive load is a predetermined value or less.
