A device for correcting a multi-phase clock signal includes a first duty ratio adjusting circuit (DRAC) to adjust a duty ratio of a first clock signal; a variable delay line (VDL) delaying a second clock signal; a second DRAC adjusting a duty ratio of the VDL output; first and second differential clock generating circuits (DFCGs) generating differential signals from first and second DRAC outputs, respectively; an edge combining circuit combining edges of outputs from the DFCGs; a duty ratio detecting circuit (DRDC) detecting a duty ratio of a first DRAC output or a first DFCG output in a first mode and of an edge combining circuit output in a second mode; a first control circuit controlling the first and second DRACs using a DRDC output in the first mode; and a second control circuit controlling the VDL using the DRDC output in the second mode.

An apparatus for generating oxygenated water by dissolving oxygen in water is disclosed. The apparatus includes a reservoir () storing drinking water, an oxygen generating unit () generating oxygen through electrolysis and supplying the oxygen into a pipe line () through which the drinking water flows, and a dissolving unit () dissolving the oxygen in the drinking water. The dissolving unit () includes a pump (), a Venturi (), and a dissolving container () and a Venturi () which are connected in series to each other. The dissolving container () is provided with an oxygen pipe () installed at an inlet portion thereof to supply the oxygen generated from the oxygen generating unit () into a center portion of the drinking water quickly supplied. Consequently, the apparatus changes physical properties and molecular structure of the drinking water to generate the micro-bubbles in the drinking water, thereby achieving the dissolved oxygen concentration of more than 150 ppm, which is beneficial to a human body. Also, since the apparatus is downsized, the use efficiency thereof is increased.
