Abstract: A water purifier is provided. A water purifier according to one aspect of the present invention may include a housing having a first accommodation space therein, and made of a paper material; a water purifier faucet disposed in the first accommodation space to receive raw water and discharge purified water; and a filter coupled to the water purifier faucet to generate the purified water by filtering the raw water, wherein the water purifier faucet includes a base frame having a second accommodation space therein in which the filter is accommodated; a water inlet module provided on one side of the base frame to supply raw water introduced from the outside to the filter; and a water outlet module provided on the other side of the base frame to receive the purified water generated by the filter and discharge it to the outside.

Abstract: A method and circuit for preventing the deterioration of picture quality in a video processor is disclosed in which, when an input color video signal is input, a clock signal for a combfilter is locked with a phase-locked loop (PLL) by a burst signal and when a monochrome video signal without the burst signal is input, the clock signal is locked by the output (quasi-burst signal) of a voltage-controlled oscillator of the PLL circuit, before the lapse of one horizontal period, so that the clock signal is constantly locked by a multiple (4 fsc) of the burst signal regardless of the presence or absence of the burst signal of the input video signal. According to a color/mono signal discriminating result, either the burst signal or the quasi-burst signal is selected as a reference signal so that the reference signal is locked to provide a clock signal having a constant phase and frequency, thereby preventing aliasing due to clock variations when the monochrome signal is input and thus improving picture quality.
