    摘要: The ER fluid comprising water-soluble starch as conductive particles contains less than 5 wt % water. The ER fluid of the present invention comprises water-soluble starch as a conductive particle which is dispersed in non-conductive media. The ER fluid of the present invention exhibits a considerable ER effect, even though the amount of water contained in the ER fluid is reduced. Thus, it can be widely applicable to water-sensitive damping devices and power devices such as a suspension system, a vibration damper or an engine mount, a break, a clutch, and so forth. And it is feasible for various fields such as an automatic and an aerospace industry.

    摘要: A high voltage DC power supplier includes: a transformer driven by a switching device, transforming an input voltage to a certain level of high voltage, and outputting the transformed high voltage; a diode and a capacitor for rectifying and smoothing the high voltage outputted from the transformer, and supplying the smoothed voltage to an ER fluid application unit; a discharge circuit for forcibly discharging the output voltage when an output voltage of the capacitor descends; and a controller for controlling a turn-on operation of the switching device on the basis of a difference value between the output voltage and a reference voltage so that the output voltage can follow a target voltage, and outputting a control signal for driving the discharge circuit to the discharge circuit when it reaches a discharge period.
