Abstract: A chiller according to the present invention comprises: a compressor for compressing a refrigerant; an oil separator for separating oil and the refrigerant discharged from the compressor; a condenser for condensing the refrigerant passing through the oil separator; and expander for expanding the refrigerant condensed in the condenser; an evaporator for cooling cold water with the refrigerant expanded in the expander and connected to a demanding place via cold water pipes; an ejector for partially passing the refrigerant compressed in the compressor and connected to the evaporator via an evaporator oil recovery path; an oil recovery path of the oil separator connected in such as manner that the oil leaked out of the oil separator passes through the oil recovery path so as to be recovered to the compressor; and an ejector outlet path connected in such a manner than the oil and the refrigerant leaked out of the ejector passes through the ejector outlet path so as to be recovered to the compressor.

Abstract: An active geometric control suspension system may include an upper arm connected to a side above and between a rear wheel-sided knuckle and a subframe, and an assist link connected to the other side above and between the knuckle and the subframe, together with a node-changeable unit, wherein the node-changeable unit includes a housing formed at a portion of the subframe, a track-variable kit detachably coupled to brackets of the housing, cam-operating rails fixed to a side of the track-variable kit, a cam disposed on the cam-operating rails of the track-variable kit to be slidable up/down along the cam-operating rails, and a cam bolt connecting the cam with a vehicle body-sided connecting portion of the assist link.

Abstract: Disclosed herein is a nano- or micro-scale organic-inorganic composite device and a method for producing the same. The nano- or micro-scale organic-inorganic composite device includes a first electrode, a second electrode, and a photoactive layer formed of a fullerene-conducting polymer composite interposed between opposing surfaces of the first electrode and the second electrode, and a method of producing a nano- or micro-scale organic-inorganic composite device capable of mass production of the nano- or micro-scale organic-inorganic composite device, by producing an integrated structure of nano- or micro-scale organic-inorganic composite devices of a uniform size and quality using a porous template, where each device includes a first and second electrode, and a photoactive layer.

Abstract: Disclosed herein are a mobile communication terminal equipped with a subscriber identification module and a method of processing an emergency call request in the mobile communication terminal. The mobile communication terminal includes: a keypad; a display unit; a RF module for communicating with a base station; and a controller for performing the overall control of the mobile communication terminal, the controller including: a PIN code input request unit for displaying a PIN code input request on the display unit when terminal booting is requested; a key data analysis unit for analyzing key data inputted through the keypad when the PIN code input request unit requests to input the PIN code; and an emergency call processing unit for searching for the base station and establishing a call connection to the base station when the key data is determined to be an emergency call request by the key data analysis unit.
