摘要:
The present invention is directed to a carbazole containing compound and an organic electroluminescent display device using the same. In particular, the carbazole containing compound may be a blue phosphorescent host material having a large triplet energy gap compared to 4,4′-N,N′-dicarbazole-biphenyl (CBP) and effectively transfers energy to a blue dopant. An organic layer formed using the carbazole containing compound may be used in an organic electroluminescent display device in order to provide high efficiency, improved color purity, and improved power consumption characteristics.

A coupling set for connecting a ground plate for arrest of lightning is provided, in which the ground plate is embedded underground below an electric pole in order to effectively arrest lightning. Accordingly, lightning can be effectively grounded. The connection members are connected with each other top and bottom and left and right. The lowest connection member is supported below an electric pole. Thus, when the electric pole is buried, a coupling set having connection members for connecting a ground plate is not be pushed up. Also, it is very easy to connect a lightning arrest copper wire with a ground terminal.

A handling system for an in-core detector thimble tube of a reactor is disclosed. The handling system serves to withdraw and retract a thimble tube so as to provide a movement path of a movable detector used to measure a neutron flux within a reactor. For this, the handling system basically includes a thimble tube withdrawing/retracting device, which grips the thimble tube using a plurality of synthetic resin pinch rollers to withdraw and retract the thimble tube without any damage to the thimble tube, a thimble tube tensioning device, which applies a constant tensile force to the thimble tube to prevent the thimble tube from shaking or bending upon withdrawing/retracting operations, and a thimble tube platform, which temporarily keeps the withdrawn thimble tube at a fixed position without a risk of shaking of the thimble tube and provides a movement path of the thimble tube tensioning device. With automatic withdrawal/retraction of the thimble tube without damage provides advantages of an extended thimble tube exchange interval, improved safety of system facilities, reduced labor costs and working time, and reduced worker radiation exposure, shortened precaution/maintenance period, and enhanced reactor use efficiency.

An organic light emitting display device having multiple emission layers is provided, in which an organic charge transport layer is interposed between the emission layers to enhance interfacial properties between layers, and thus a stable process is ensured. Further, a hole transport layer and an electron transport layer are formed of an organic material like the charge transport layer, thereby simplifying the process.
