摘要： A data multiplexing system which includes a plurality of data multiplexing buses through which a plurality of low-speed digital signals are collected into, and distributed from, a multiplexer/demultiplxer. In a data multiplexing mode, the low-speed digital signals entered from a plurality of low-speed transmission lines have their signal format converted by respectively corresponding low-speed interface circuits, and the resulting signals are multiplexed in time slots designated within a multiplexed signal of primary level on the up bus line of the corresponding data multiplexing bus. The high-speed multiplexer multiplexes the collected signals up to a predetermined signal level and sends the resulting secondary multiplexed signal to a high-speed interface module having a high-speed transmission line interface. The high-speed interface module converts the received secondary multiplexed signal and sends the resulting signal to the high-speed transmission line. The signal of the high-speed transmission line is processed by the high-speed interface module and the high-speed demultiplexer, and the low-speed digital signals are sent to the low-speed transmission lines.

摘要： A heavy oil is hydrorefined using a hydrorefining catalyst. A spent hydrorefining catalyst whose activity has decreased is heat treated (S1) and pulverized to obtained a regenerated powder (S2). This regenerated powder is fractionated according to its metal content (S3), formed (S6), dried (S7), and calcined (S7) to manufacture a regenerated catalyst whose volume of pores with a diameter of 50 to 2000 nm is at least 0.2 ml/g, and whose volume of pores with a diameter over 2000 nm is no more than 0.1 mL/g. Using this regenerated catalyst, a heavy oil containing at least 45 wt ppm vanadium and nickel as combined metal elements is hydrodemetalized, and the vanadium and nickel are recovered from the used regenerated catalyst (SS1). Through hydrorefining, the metal components are recovered more efficiently, and the spent catalyst can be reused to manufacture a regenerated catalyst that exhibits high reaction activity.

摘要： A data multiplexing system comprising a plurality of data multiplexing buses through which a plurality of low-speed digital signals are collected into, and distributed from, a multiplexer/demultiplexer. In a data multiplexing mode, the low-speed digital signals entered from a plurality of low-speed transmission lines have their signal format converted by respectively corresponding low-speed interface circuits, and the resulting signals are multiplexed in time slots designated within a multiplexed signal of primary level on the up bus line of the corresponding data multiplexing bus, under the controls of respectively corresponding bus control circuits. The high-speed multiplexer collects the primary multiplexed signals on the up bus lines of the plurality of data multiplexing buses, and further multiplexes the collected signals up to a predetermined signal level. Thereafter, it sends the resulting secondary multiplexed signal to a high-speed interface module having a high-speed transmission line interface. The high-speed interface module converts the received secondary multiplexed signal so as to match the interface of a high-speed transmission line, and sends the resulting signal to the high-speed transmission line. In a data demultiplexing mode, the signal of the high-speed transmission line is processed by the high-speed interface module and the high-speed demultiplexer, and the resulting signals are distributed through the down bus lines of the data multiplexing buses so as to send the low-speed digital signals to the low-speed transmission lines.
