    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.

    摘要： A double pipe and a heat exchanger having the same are provided. The double pipe including an outer pipe and an inner pipe formed within the outer pipe includes: a plurality of barrier ribs formed in a length direction and disposed at a predetermined distance in a circumferential direction between the outer pipe and the inner pipe; and a plurality of protruding portions formed at positions corresponding to each of the plurality of barrier ribs and protruded in a center direction and formed in a length direction of the inner pipe from an inner circumferential surface of the inner pipe. Therefore, by improving heat exchange efficiency by the heat exchanger having the double pipe, cooling efficiency of a cooling system can be improved.

    摘要： A can type secondary battery. The can type secondary battery has a fixing unit for fixing an end portion of a terminal plate to an end portion of an insulation plate of a cap assembly in order to prevent a short circuit between the terminal plate and an electrode assembly by preventing the terminal plate from being deformed due to external force or external pressure applied to the can type secondary battery, thereby improving safety of the secondary battery.
