Abstract: Disclosed is a low power modulator with a VCO quantizer. The low power modulator with the VCO quantizer may include an integrator converting an input current to a voltage, a quantizer converting the converted voltage to digital information, a filter unit filtering the converted digital information, a DAC converting the filtered digital information into a feedback current, and a controller calculating the digital information output based on a difference value between the input current and the feedback current for each sampling time.

Abstract: The present disclosure relates to emulsified oil composition including an oil containing a polyunsaturated fatty acid which is applicable to food, a rosemary extract, and a non-ionic surfactant, wherein the product quality of the food using the oil containing the polyunsaturated fatty acid is maintained during the processing and storage of the food, by preventing the oxidation of the oil containing the polyunsaturated fatty acid to suppress the production of a rancid flavor and an off-flavor.

Abstract: An indoor unit of an air conditioner includes a frame of the indoor unit; a heat exchanger mounted on the frame and having a refrigerant pipe in which a refrigerant flows; a hanger plate mounted on a rear surface of the frame and configured to fix the frame onto a wall surface; and a holder plate mounted on a lower portion of the frame and connecting the frame and the hanger plate. An end of the refrigerant pipe is placed in a space formed by the frame, the holder plate, and the hanger plate. The holder plate is movably connected on a lower portion of the frame, so the refrigerant pipe is accessible to a user to perform an operation of connecting or separating the refrigerant pipe to or from a connection pipe connected to an outdoor unit without rotating the frame.

Abstract: An indoor unit of an air conditioner having an improved frame structure in which a refrigerant pipe that connects an outdoor unit and the indoor unit can be easily connected. The indoor unit of the air conditioner includes: a frame; a heat exchanger mounted on the frame and having a refrigerant pipe in which a refrigerant flows; a hanger plate mounted on a rear surface of the frame and fixing the frame onto a wall surface; and a holder plate mounted on a lower portion of the frame, fixing the frame and the hanger plate, and supported by a fixing member of the wall surface. The holder plate selectively opens/closes the lower portion of the frame so that a pipe connection operation can be easily performed.
