    摘要： There is provided a magnetic microvalve using a metal ball and a method of manufacturing the same. A magnetic microvalve using a metal ball according to an aspect of the invention may include: an upper substrate having a microchannel serving as a passage through which a fluid moves, a fluid inlet through which the fluid flows into the microchannel, and a fluid outlet through which the fluid, having passed through the microchannel, flows out of the microchannel; a lower substrate having a trench locally provided therein; a PDMS/metal ball combination having a metal ball and PDMS surrounding the metal ball so that the metal ball is located in a central portion thereof, the PDMS/metal ball combination being inserted into the trench provided in the lower substrate; and a magnet located above the microchannel, provided in the upper substrate, and generating magnetic force.

    摘要： An arc-free phase control circuit for an AC motor that brings about an energy saving effect according to a load change and operates efficiently in terms of cost reduction while securing electrical stability by virtue of an overload protection function. The circuit includes a first relay, a TRIAC, a second relay, a voltage sensing unit, a current sensing unit, a speed voltage sensing unit, a zero-cross point detection unit, and a controller.
