摘要:
Disclosed herein is an apparatus for controlling the capacity of an air conditioner and a control method using the same. The capacity control apparatus is configured in such a fashion that a 3-way or 4-way direction-switching member and a low-pressure equalizing solenoid valve are provided at a refrigerant path of the air conditioner having a pair of first and second compressors, so that the compression capacity of the air conditioner is adjusted into three stages of 100%, 60%, and 40% using the first and second compressors, enabling easy variable-capacity operation. This has the effect of considerably reducing energy consumption and of preventing wear of the first and second compressors via a rapid compensation of a pressure unbalance between both the compressors. As a result, under any operating condition, it is possible to prevent a liquid backflow phenomenon from occurring when starting operation of the compressors, resulting in an improvement in the reliability and operation efficiency of the compressors.

The present invention relates to plasma display panel and manufacturing method thereof to simplify the manufacturing steps and reduce cost of production. In the present invention, a black layer formed between a transparent electrode and a bus electrode is formed together with a black matrix at the same time. In this case, the black layer is formed together with the black matrix in one. Cheap nonconductive oxide is used as a black powder of a black layer. Specifically, in case the black layer and the black matrix are formed in one, the bus electrode is shifted to a non-discharge area to improve the brightness of the plasma display panel.

A method for supporting handoff and preventing data loss in mobile communications networks is provided. The method for a mobile node establishing a mobile Internet protocol (MIP) with at least one or more wireless packet service systems, each of which has a serving GPRS support node (SGSN) and a gateway GPRS support node (GGSN), includes: a first SGSN connected to the mobile node transmitting predetermined first connection information on the mobile node to at least one or more second SGSNs adjacent to the first SGSN; the second SGSN receiving the first connection information storing the first connection information as a database item, and transmitting 1 first connection acknowledgement message to the first SGSN; if reception of the connection acknowledgement message is successful, the first GGSN connected to the first SGSN transmitting predetermined second connection information on the mobile node to at least one or more second GGSNs connected to the second SGSN; and the second GGSN receiving the second connection information and then transmitting a second connection acknowledgement message to the second GGSN. By transmitting information on a mobile node required for handoff to adjacent foreign agents (FAs) in advance, when handoff is performed, reliable handoff can be performed quickly without resetting and releasing a PPP, such that IP mobility services can be provided.

There is disclosed a connection structure and method of a plasma display panel that is adaptive for preventing a short circuit caused by conductive ball mass and improving connection cohesiveness. A connection structure of a plasma display panel according to an embodiment of the present invention includes a first substrate having a plurality of panel-electrodes; a second substrate having a plurality of connecting-electrodes arranged to correspond to the panel-electrodes; and a connection member located between the first substrate and the second substrate to directly connect the connecting-electrodes with the panel-electrodes upon compression. Accordingly, there is no conductive ball, so the occurrence of short circuit caused by the conductive ball mass of prior art is prevented and, at the same time, the copper electrode penetrates the panel-electrode, thereby improving connection cohesiveness.

A method of manufacturing a nozzle for an inkjet head is disclosed. With the method of manufacturing a nozzle for an inkjet head, comprising (a) coating photoresist on an inkjet head structure comprising a nozzle part; (b) adjusting exposure conditions and performing exposure and developing on the nozzle part to remove a portion of the photoresist; (c) joining a hydrophobic layer onto the portion of the nozzle part where the photoresist has been removed; and (d) removing the photoresist remaining on the nozzle part, it is easy to control the depth of the hydrophobic layer to be uniform, and the depth to which the hydrophobic layer is deposited may be controlled even when the back surface of the nozzle has a complex shape, so that the uniformity and reproduction of the hydrophobicity-treated nozzles are improved.

The present invention provides a method and system for providing a SIP based Instance Messaging (IM), and an IM proxy server therefor. An IM proxy server for performing a proxy function in a mobile communication network is configured to provide an IM service between a mobile terminal lacking an SIP function and an IM server. Further, the IM proxy server converts an IM message received from the mobile terminal into a corresponding SIP message mapped thereto, transmits the SIP message to the IM server through a call session control server, converts an SIP message received from the IM server through the call session control server into an IM message recognizable by the mobile terminal, and transmits the IM message to the mobile terminal, thus providing the SIP based IM service to the mobile terminal lacking an SIP function.

Disclosed herein are an elastic steel band, which is wound over one revolution (angle of over 360°) when a sun cap or a hat is not worn, whereby keeping and portability characteristics of the sun cap or hat are improved, and method and apparatus for manufacturing the same. According to the present invention, the method of manufacturing the elastic steel band includes a material preparation step, a press work step of forming a unit work pieces, a rolling step of rolling the unit work piece 1.5 revolution to less than 3 revolutions, and an unfolding step of bending both ends of the rolled half-finished work piece in an opposite direction to the rolling direction, thus forming unfolded units at both ends of the elastic steel band.
