    摘要: The variable lamination rapid prototyping apparatus of the present invention includes a first feeding means which longitudinally reciprocates a sheet, a second feeding means which is provided under the first feeding means and reciprocates in a direction transverse to the sheet, and a rotating means which is coupled to the second feeding means and rotates around an axis parallel to the transverse direction of the sheet. The apparatus further includes a translation means which is linked to the rotating means, a cutting means which is coupled to the translation means, and a stacking means which subsequently stacks a plurality of cut sheets, thus forming the 3-dimensional object. The apparatus further includes a control means which previously stores data about the object therein and controls the above-mentioned plurality of means based on the data. Because a hot wire is provided in a parallelogram link structure, superior cutting accuracy and the stability are ensured. Furthermore, because the link structure is adjustable in length, it is possible to easily cut a sheet regardless of the size of the sheet.

    摘要: Disclosed is a system and a method for polling in an Ether net Passive Optical Network (EPON). The system includes: multiple Optical Network Units (ONUs) for sharing optical channels of the EPON with one another and transmitting traffic; and an Optical Line Terminal (OLT) for discriminating a plurality of ONUs gaining access to the EPON among the multiple ONUs and then collecting routing information on the plurality of ONUs gaining access to the EPON, and for classifying the plurality of ONUs gaining access to the EPON into two or more ONU groups according to the collected routing information and then carrying out forming a polling cycle and allocating bandwidth on each ONU group. Therefore, a transmission idle period in a traffic channel is not only minimized, but an availability ratio of traffic channels can also be maximized.

    摘要: An apparatus for generating a road surface reaction force in a test apparatus for a steer-by-wire system includes a steering actuation unit, and actuators arranged in parallel to tie rods of the steering actuation unit. In accordance with this arrangement, there is an advantage of a reduced installation space. Also, it is possible to transmit the force of each actuator to the associated tie rod without loss, and thus, to accurately implement the generation of a road surface reaction force.

    摘要: A system and method for controlling transmission of a radio packet data are disclosed. A time point when a congestion controlling mechanism, causing a TCP performance degradation with the mobile station and the PDSN, is previously detected, and when the mechanism is operated, it is quickly returned. Thus, in spite of a bit error (data loss) existing due to the characteristics of the radio data service, a reliable data service can be guaranteed.

    摘要: An apparatus for cleaning a wafer includes a plurality of holders for contacting and securing peripheral portions of a wafer, and for rotating the wafer, a first plate disposed to face a first surface of the wafer, the first plate having a plurality of first nozzles for spraying a first cleaning solution onto the first surface of the wafer, and a second plate disposed to face a second surface of the wafer that is opposite to the first surface, the second plate having a plurality of second nozzles for spraying a second cleaning solution onto the second surface of the wafer. In operation, the first and second plates and the wafer are rotated in opposite directions. The opposite rotation causes the cleaning solutions to flow abruptly thereby increasing a frictional force between the surfaces on the wafer and the cleaning solutions to improve the efficiency of the cleaning process.
