Title: Indirect illumination and ventilation system for elevators
Inventor: YOON II SHIK
IPC: F21Y101/00
Filed: 2004-05-29
Abstract: An indirect illumination and ventilation system for an elevator has illumination shielding devices mounted under ventilation outlets for guiding air from blowers disposed above the ceiling of the elevator cage toward the internal space of the elevator cage. The illumination shielding devices have a plurality of inclined long rectangular plates arranged in parallel with spaces between each other and having lower portions inclined toward the sidewalls of the elevator cage. An illuminator is disposed between the illumination shielding device and the ceiling of the elevator cage so as to be screened by the illumination shielding device. Air flowing from the ventilation outlets sequentially passes through the illuminators and the illumination shielding devices and then is blown towards the internal space of the elevator cage. Light emitted from the illuminators is directed toward the sidewalls of the elevator cage through the inclined plates of the illumination shielding devices, thereby preventing dust or the like from accumulating on the illumination shielding devices as well as preventing the light from directly illuminating passengers in the elevator cage.

Abstract: A system for scheduling multicast packets through an interconnection network, comprising r1 input ports with each input port having r2 input queues, r2 output ports with each output port having r1 output queues, and the interconnection network having a speedup of at least s with s subnetworks, and each subnetwork comprising at least one first internal link connected to each input port for a total of at least r1 first internal link, each subnetwork further comprising at least one second internal link connected to each output port for a total of at least r2 second internal links is operated in strictly nonblocking manner in accordance with the invention by scheduling, at most r1 packets in each switching time be switched in at most r2 switching times when r1.subseteq. r2, and at most r2 packets in each switching time to be switched in at most r1 switching times when r2.subseteq.r1, in deterministic manner, and without the requirement of segmentation and reassembly of packets. The scheduling is performed so that each multicast packet is fan-out split through not more than two interconnection networks and not more than two switching times. The system is also operated at 100 % throughout, work conserving, fair, and yet deterministically thereby never congesting the output ports. The system performs only one iteration for arbitration, and with mathematical minimum speedup in the interconnection network. The system operates with absolutely no packet reordering issues, no internal buffering of packets in the interconnection network, and hence in a truly cut-through and distributed manner. In one embodiment, the speedup is implemented with only one interconnection network and with triple switching rate through the interconnection network. In another embodiment, the system is operated in rearrangeably nonblocking manner with a speedup of at least s in the interconnection network. When the number of input ports r1 is equal to the number of output ports r2, and r1 = r2 = r, the interconnection network having a speedup of at least s, is operated in strictly nonblocking and deterministic manner in accordance with the invention by scheduling at most r packets in each switching time to be switched in at most r switching times. And with a speedup of at least s in the interconnection network, the system is operated in rearrangeably nonblocking and deterministic manner. The system also offers end to end guaranteed bandwidth and latency for multicast packets from input ports to output ports. In all the embodiments, the interconnection network may crossbar network, shared memory network, clos network, hypercube network, or any internally nonblocking interconnection network or network of networks.

Title: Method for efficiently producing an aromatic polycarbonate
Inventor: FUKUOKA SHINSUKE
IPC: C08G64/04
Filed: 2005-06-14
Abstract: A process by which a high-quality and high-performance aromatic polycarbonate having no color and excellent mechanical properties can be stably produced for long from a molten prepolymer of an aromatic polycarbonate obtained from an aromatic dihydroxy compound and a diaryl carbonate, on an industrial scale of 1-50 tons per hour without using a large amount of an inert gas. The process, which is for producing an aromatic polycarbonate by the melt method, comprises absorbing a specific amount of an inert gas into a molten prepolymer of an aromatic polycarbonate obtained by the reaction of an aromatic dihydroxy compound with a diaryl carbonate and then polymerizing the prepolymer with a polymerizer of the guide contact flowing-down type having a specific structure. Thus, a high-quality and high-performance aromatic polycarbonate having no color and excellent mechanical properties can be stably produced on an industrial scale at an output of 1-50 tons per hour over a period as long as several thousands of hours, e.g., 5,000 hours, without causing fluctuations in molecular weight, etc.
