Title: Direct memory accessing system
Inventor: MARUI YOJI
IPC: G06F13/28
Filed: 1985-10-03
Abstract: PURPOSE:To reduce an information transfer time by providing independently a direct information transferring exclusive connection path between a main storage device and an input/output controller separated from a processor bus. CONSTITUTION:When an input/output controller 3 transfers information from a main storage device 2 to an input/output device 4, or, from the input/output device 4 to the main storage device 2, it transfers a direct memory access request to the main controller 1. The main controller 1 accumulates the start information (s) of logic '1' at an internal register 71 provided within a transfer control part 7 and an internal register 81 provided within the input/output controller 3. Consequently, the transfer control parts 7 and 8 cut off their connections to a processor bus 5 respectively, and set the connections to a DMA bypass 6. As a result, a direct connection path that passes through the DMA bypass 6 is set between the main storage device 2 and the input/output controller 3. Thereby, a time required for the information transfer is reduced and also, the lowering of the processing efficiency of the main controller can be prevented.

IPC: B24B53/00
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To dress a hemispherical tool by making it come into contact with a gel coating inclusive of abrasive grains formed in a formed positive electrode, as relatively rotating a grinding tool and this formed electrode. SOLUTION: A formed negative electrode 26 is opposedly installed in a recess 20a of a positive electrode hold-down member 20 at an opposite minute interval δto a formed electrode 18. A desired d.c. voltage or current is impressed to a gap between the formed electrode 18 and the formed electrode 26. When an electrode field is formed in a grinding fluid in space between the electrode 18 and the electrode 26, a surface of the formed electrode 18 attracts abrasive grains by an electrophoretic phenomenon. Therefore, the abrasive grains are hydrophobicly adsorbed on a surface of the electrode 18, forming a gel coating being high in grain density. In this state intact, a ball grinding wheel 30 is dressed by making it come into contact with the gel coating formed on the surface of the electrode 18, as rotating this ball grinding wheel 30 and the electrode 18.
