An ATM switching system comprises a switch unit including a plurality of input ports and a plurality of output ports having the same cell transmission rate, and a multiplexer for multiplexing cell trains outputted from at least two output ports into a single cell train and outputting the cell train to a high-speed output line (and/or a demultiplexer for demultiplexing a cell train from an output port into a plurality of cell trains and outputting the cell trains to a plurality of low-speed output lines). The switch unit includes a buffer memory for temporarily storing cells inputted from the input ports while forming a queue chain for each output line to which each cell is to be outputted, a demultiplexer for distributing the cells read from the buffer memory among the output ports in circulation, and a buffer memory control circuit for controlling the write and read operation of cells with the shared buffer memory. The buffer memory control circuit has a control table device for outputting an identifier of an output line to which the cells read from the shared buffer memory are to be outputted, and cells are read from the chain designated by the output line identifier outputted from the control table device.

The present invention relates to a process for preparing a coal-water slurry comprising the steps of screening coal into a coarse-grained coal and a fine-grained coal; subjecting said coarse-grained coal to gravity classification to classify into a low ash coal, a middle ash coal and a high ash coal; wet grinding a mixture of the fine-grained coal, the middle ash coal and part of the low ash coal, and subjecting same to flotation; preparing a first slurry having a solid concentration of 40-60 wt. % from the low ash froth resultant from flotation; and mixing another part of the low ash coal with this first slurry and wet grinding this mixture. This process can accord the solid concentration of the product slurry with an optional target value by adjusting the amount of the low ash coal mixed with the first slurry, and can use the remaining low ash coal not to be added to the first slurry for the purpose of preparing the second product slurry.

A light-emitting apparatus of a cultivation system includes a first light source array and a second light source array adjacent to the first light source array. The first light source array includes first light sources and second light sources. The first and second light sources are arranged in a specific pattern in a predetermined direction. The second light source array includes first light sources and second light sources. The first and second light sources of the second light source array are arranged in the specific pattern in the predetermined direction such that an arrangement of colors of the first and second light sources in the second light source array is shifted from an arrangement of colors of the first and second light sources in the first light source array.

A series of substrate transport paths for transporting substrates is arranged on upper and lower stories. Substrates are transferable between the substrate transport path on the first story and the substrate transport path on the second story. The paths include a going-only path for transporting the substrates forward, and a return-only path for transporting the substrates in the opposite direction, these paths being arranged on the upper and lower stories. An indexer connects one end of the substrate transport path on one story to one end of the substrate transport path on the other story. An interface connects the other end of the substrate transport path on one story to the other end of the substrate transport path on the other story. This construction efficiently reduces a waiting time due to interference between the substrates transported along the going-only path and the substrates transported along the return-only path.

摘要:
A substrate processing apparatus includes a coating section, a developing section, a heat-treating section and a transport mechanism. The coating section has first processing units each for performing a coverage process to supply a photoresist solution to a substrate and cover a surface of the substrate with the photoresist solution, a second processing unit for spinning the substrate, after the coverage process, at high speed to make the photoresist solution into a film, dry the photoresist film, and clean the substrate. All substrates are processed with the same coating conditions to suppress differences in quality among the substrates. The first and second processing units perform the respective processes concurrently to improve the throughput of substrate processing.
