The apparatus for detecting a zero crossing and a voltage amplitude from a single pulse signal includes: a first calculation unit that compares the commercial power source voltage to a first reference voltage to determine whether or not the commercial power source voltage is smaller than the first reference voltage; a second calculation unit that compares the commercial power source voltage to a second reference voltage smaller than the first reference voltage to determine whether or not the commercial power source voltage is larger than the second reference voltage; a pulse output unit that outputs a pulse if the commercial power source voltage is smaller than the first reference voltage but larger than the second reference voltage; and a detecting unit that detects a zero crossing and a voltage amplitude by analyzing the pulse which has been outputted from the pulse output unit. | 10-29-2009 |
20090165322 | Drier for food waste disposal system - A drier for a food waste disposal system. A hollow drum has a charge port and a discharge port for food waste. An agitating screw has a rotating thread which is rotatably disposed in an inner space of the drum and agitates and crushes the food waste, and a rotating shaft around which the rotating thread is disposed. A motor is installed on a first end of the drum, and provides a rotating force to the agitating screw. A crusher has a crush plate installed on a second end of the drum and a plurality of inclined crushing blades arranged radially, and a crush plate support installed around an upper portion of the crush plate. A heater is installed on an outer surface of the drum, and when powered provides high-temperature heat for the inner space of the drum, drying the food waste. | 07-02-2009 |
20090107897 | AUTOMATIC FLUSHING APPARATUS OF MEMBRANE FILTER IN WATER PURIFIER - A water purifier including a sediment filter ( | 04-30-2009 |
20080264846 | WATER PURIFYING APPARATUS - Provided is a water purifying apparatus. The water purifying apparatus includes a filter unit for filtering water to obtain purified water; a purified water pipe through which the purified water discharged from the filter unit flows; and a cooling unit having the purified water pipe passed therethrough and cooling the purified water pipe to generate cold water. Therefore, the water purifying apparatus may be useful to prevent cold water from being contaminated and re-contaminated, suppress scales from being accumulated therein and obtain water with desired pH density. | 10-30-2008 |
