摘要:
A heat pump air conditioner includes an outdoor unit for heating use only for supplementing heating capacity when additional heating capacity must be provided to the heating capacity of an outdoor unit for heating and cooling in a heating mode. Since the outdoor unit for heating use only is installed independent from the outdoor units for heating and cooling use, such that the outdoor unit for heating use only can supplement the heating capacity only when the additional heating capacity is required in addition to the heating capacity of the outdoor units for heating and cooling use in the heating mode, in order to correspond to the heating load in cold climes, there is no need to install an outdoor unit having larger heating capacity than the required heating capacity. Thus, costs for installation and management are reduced.

A database query system is provided. The database cache system includes: a network library which processes an access request issued by the online game server by using an input output completion port (IOCP); at least one database connection module which provides a connector for reading data from the database or recording data to the database; a database cache which stores data read from the database by the database connection module; and at least one cache buffer which is allotted to an IOCP worker thread corresponding to a database query request issued by the online game server and stores data read from the database, which is to be transmitted to the online game server.

A method for controlling a multi-unit air conditioning system adapted to cool or heat room spaces while passing a refrigerant in one direction or in a reverse direction is disclosed. In the method, which is applied to a multi-unit air conditioning system including at least three compressors, when a compressor re-operation is repeatedly carried out after all of the compressors have been turned off, to turn on again at least one of the compressors, repetition of the compressor re-operation is carried out for a predetermined number of different orders in such a manner that at least one of the compressors is turned on first in an associated order of the repeated compressor re-operation.

A light emitting display includes a substrate, a pixel area, a first power source line to supply a first power signal to each pixel on a first side of the pixel area, a second power source line to supply the first power signal to each pixel on a second side of the pixel area, and an impedance compensator for compensating a difference in a voltage drop between the first power source line and the second power source line. A voltage drop caused by line resistance that depends on the length of the first and second power source line that supply the first power signal to a lower and upper side of a pixel area, respectively, is equalized, thereby minimizing the voltage drop of the first power signal supplied to all pixels, and minimizing non-uniformity of brightness due to the voltage drop differences at each pixel.

Disclosed is a method of transmitting emergency stop control information on a common packet channel (CPCH) in a mobile communication system, which can perform an emergency stop within a less period of time when the user equipment is in a state of transmitting a packet through the CPCH by rapidly transmitting he emergency stop control information. The method of transmitting emergency stop control information on a CPCH is a radio mobile communication system comprises a first step of inserting and transmitting a predetermined bit pattern to a downlink (DL) dedicated physical channel (DPCH) by a universal mobile terrestrial radio access network (UTRAN), a second step of recognizing the particular bit pattern by the UE, and a third step of controlling data transmission through an uplink (UL) CPCH by the UE. Thus, the method according to the invention has an effect of more rapidly transmitting urgent control information through the DL DPCCH or the DPDCH, which are related to the CPCH, or through both of these two channels when the UE is transmitting a packet through the CPCH currently allocated to the UE.
摘要:
By mooring or slowly moving the catamaran in a current through which a garage patch formed of disused plastic particles over than 90% is drifting, a heap of the marine debris flows into the bow of the catamaran and then is smashed. While the disused plastic particles that have been smashed at the bow of the catamaran is moving from the bow toward the stern by way of the tunnel between hulls of the catamaran, the plastic particles are first classified by differences of densities. These first classified plastic particles are collected and then transferred into a narrow and long inside of the catamaran, being finally classified by a triboelectrostatic action. Thereafter, these finally classified plastic particles are made to be pallets which are to be transported to a land facility for recycling or abandoning them.

Disclosed are an exposure method and a method of manufacturing a mask and a semiconductor device using the same, which minimize time taken by mask data preparation (MDP) to optimize a total exposure process and enhance a quality of a pattern by using an inverse solution concept, based on a multi-beam mask writer. The exposure method includes receiving mask tape output (MTO) design data obtained through optical proximity correction (OPC), preparing mask data, including a job deck, for the MTO design data without a data format conversion, performing complex correction, including proximity effect correction (PEC) of an error caused by an e-beam proximity effect and mask process correction (MPC) of an error caused by an exposure process, on the mask data, generating pixel data, based on data for which the complex correction is performed, and performing e-beam writing on a substrate for a mask, based on the pixel data.
