Abstract: The present invention relates to an organometallic iridium compound and application thereof. The organometallic iridium compound has a general formula of Ir(La)(Lb)(Lc), where La is a structure represented by Formula (1), and Lb is a structure represented by Formula (2). The compound provided by the present invention has the advantages of high optical and electrical stability, low sublimation temperature, small emission half-peak width, high color saturation, high luminous efficiency, long device life and the like, and can be used in organic electroluminescent devices. In particular, the compound has the potential for application in the AMOLED industry as a red light-emitting dopant, especially in display, lighting and automobile taillights.

Abstract: An automatic fire door closing device includes a hydraulic main engine, an arm rod, a rotating shaft, a connecting plate and a clamping device, and further comprises a fire monitoring and response device and a driving device. The driving device includes a linkage rod rotatably connected to the connecting plate, a transmission column rotatably connected to the connecting plate, and a transmission rod fixedly connected to the transmission column, one end of the linkage rod has a hook part for hooking the transmission rod, and the transmission column cooperates with the clamping device, when smoke or open fire is monitored, the hook part of the linkage rod is disengaged from the transmission rod, and the rotation of the transmission column makes the clamping device to release the rotating shaft. The device reduces cost with simple structure, high integration and low installation difficulty.

Abstract: In one example, a device for partially dried inkjet media output management includes a starwheel positioned on a first side between a number of rollers positioned on a second side to corrugate partially dried inkjet media between the starwheel and the number of rollers.

Abstract: A method for providing a core network service for a user of a third-party service provider is provided, where the method comprises: receiving, when the user of the third-party service provider logins a core network with a third-party ID, from the third-party service provider the third-party ID and a temporary core network ID assigned to the user for registration; storing the third-party ID and mapping the third-party ID to the temporary core network ID in the core network; and confirming the successful registration of the third-party ID to the user. The method further comprises: upon the successful registration of the third-party ID, the user may originate a call with the third-party ID as an origination ID or a termination ID, and the core network may carry out a billing and a call tracing associated with the third-party ID.

Abstract: A chassis with horizontal plugged frames includes an air inlet, a board area, a first air chamber, a second air chamber, and an air outlet. The air inlet is set in the board area and is linked to the first air chamber; the air outlet is set on a wall of the second air chamber where the second air chamber contacts external air; and the first air chamber is located on one side of the board area, and the second air chamber is located on the other side of the board area.
