摘要:
A processor bus linked with at least a processor, a memory bus linked with a main memory, and a system bus linked with at least an input/output device are connected to a three-way connection control system. The control system includes a bus-memory connection controller connected to address buses and control buses respectively of the processor, memory, and system buses to transfer address and control signals therebetween. The control system further includes a data path switch connected to data buses respectively of the processor, memory, and system buses to transfer data via the data buses therebetween depending on the data path control signal.

摘要:
A working system for an aeroplane comprising a hangar for accommodating the aeroplane, a partition wall provided within the hangar for partitioning the hangar into a fuselage work area around a fuselage of the aeroplane and a main wing work area around a main wing, and working tables arranged in the fuselage work area. The partition wall is movable between a predetermined partitioning position and a retracted position allowing entrance and exit of the aeroplane. The working tables are movable within the fuselage work area separately from the partition wall.

A surfactant composition has good emulsifiability for monomer(s), and can provide a polymer emulsion (herein after simply called “the emulsion”) of good stability while decreasing coagulations of polymer particles in the emulsion. The surfactant composition contains the following components (A) and (B): (A) a reactive surfactant containing at least one polymerizable double-bond group and at least one ionic group in a molecule, and (B) a nitrogen compound insoluble or slightly soluble in ethanol. A weight ratio (A:B) of the component (A) to the component (B) is from 100:0.03 to 100:1.0.

摘要:
In a computer system having an address converter for DMA (direct memory access), an address conversion apparatus in which a memory area to be accessed by the DMA can be accessed at high speed from a CPU. A "DMA address conversion area" is defined in a memory space, and address conversion means in the mode of accessing the DMA address conversion area is so constructed that, when the area has been accessed from the CPU, a physical address is generated in accordance with the address conversion routine of the DMA address conversion means or converter, so as to access a main storage. The memory area to be accessed by the DMA can be quickly accessed from the CPU without requiring such an operation as especially accessing the control ware of the address converter or producing the physical address under the management of a program run on the CPU.
