The present invention relates to a method for detecting loss in DRX synchronization in a telecommunications system. The method includes receiving at the synchronizing node a second reference frame at a second time and transmitting from the synchronizing node to the first reference node a short timing contention time frame. It further has a structure for delivering atoms between droplets, wherein the droplets are nanoparticles. Discharge current generated between each conductive film 15 and a rear plate 21 is caused to flow into the conductive area 12 by applying anode voltage to the conductive area 12, which suppresses influence on an electron-emitting device 23. The opening has a first dimension measured along the long axis of the conductive pillar and a second dimension measured along the short axis of the conductive pillar. A rotary lobe pump is used to pump the viscous material and a rotary pump driven by the same gearbox delivers the secondary fluid.
