摘要:
A method and an apparatus for interworking between base stations using a GateWay (GW) in a wireless communication system of a hierarchical cell structure are provided. In the method, a message requesting Internet Protocol (IP) information of a target eNB is received from a source eNB. The IP information of the target eNB is obtained. The source eNB is mapped to the target eNB and the mapping is stored. IP information of the GW is transmitted to the source eNB instead of the IP of the target eNB.

A display device and a fabrication method thereof are provided. In a dual-link structure for a narrow bezel, first link wirings are formed on the same layer that the gate lines are formed and second link wirings are formed on the same layer that the data lines are formed. The first link wirings and the second link wirings are formed in a non-display area. Or auxiliary link wirings are further formed over the first link wirings and the second link wirings respectively. Or the first link wiring and second link wiring are divided two pieces of sub-link wirings. The sub-link wirings consisting the one link wiring are connected respectively and are formed on the different layer, whereby a defective image due to a difference in resistance between neighboring link wirings can be improved.

The present invention relates to a device for controlling a hydraulic pump of construction machinery. The device has a first pump supplying working fluid through a swing control valve to a swing motor, and a second pump supplying working fluid through a work tool control valve to a work tool actuator, and includes: a first tilting angle control unit for controlling a discharge flow of the first pump by controlling a tilting angle of the first pump according to an input pump control signal; and a controller deducting a discharge pressure (P2) of the second pump from a discharge pressure (P1) of the first pump to calculate a pump difference pressure-(P1-P2), comparing the calculated pump difference pressure (P1-P2) to a reference difference pressure and, when the calculated pump difference pressure (P1-P2) is greater than the reference difference pressure, outputting the pump control signal to the first tilting angle control unit to make the discharge pressure (P1) of the first pump equal to or less than a first reference pressure that is less than or equal to a swing relief pressure.

A method of producing a carbon material which is mainly composed of graphene-containing carbon particles is provided. The method includes a step of producing carbon particles from an organic material by maintaining a mixture containing the organic substance as a starting material, hydrogen peroxide and water under conditions of a temperature of 300° C. to 1000° C. and a pressure of 22 MPa or more. The method further includes a step of heat-treating the carbon particles at a higher temperature than the temperature maintained in the carbon particle producing step. The carbon material produced by the present method has a structure in which substances such as ions can easily enter and leave the graphene structures of the carbon particles, making the carbon material be useful as active materials of secondary batteries and electric double layer capacitors.

The present invention relates to an apparatus, and to a method, for a telematics service for linking a terminal device, carried by a user, to an electronic vehicle control device mounted in a vehicle in order to provide a telematics service related to the vehicle, thus enabling a driver of the vehicle to easily use various audio-based message services while driving. Through a link between the terminal device and the vehicle electronic control device, an intended lane change can be distinguished from a lane departure caused by inattention while driving, the lane departure can be sensed, and the driver, a passenger, or a driver of another vehicle can be alerted in order to induce safe driving.

The branching apparatus according to the present invention includes two power supply terminals mounted on a saddle in the opposite direction of a branch connection part branched from a cylindrical body, so that they are not overlapped with the branch connection part when an electric socket is connected to the power supply terminal, and hence, it provides easiness in work. Moreover, because the branch connection part is slantly mounted directly above the main pipe, a trace wire inserted into the branch connection part and the main pipe is not bent, and hence, the trace wire can trace exact length and position.
