Title: Communication control circuit with redundancy
Inventor: KANG WOO-SIK
IPC: G06F13/38
Filed: 1992-06-26
Granted: 1996-01-25
Abstract: a local memory; a common memory connected between a common address bus and a common data bus; a first buffer for connecting the common address to the local address bus; a second buffer for connecting the common data bus to the local data bus; a third buffer for connecting the common address bus to a VME address bus; a fourth buffer for connecting the common data bus to a VME data bus; a first central processing unit for accessing the local memory and the common memory through the first and second buffers; a second central processing unit for accessing the common memory through the third and fourth buffers and commonly sharing data with the first central processing unit; a bus error controller for generating an error signal until an upper data strobe signal is set; a data error transmission recognition generator for generating a bus error signal; a bus mediator for applying a data transmission recognition signal and the bus error signal to a master unit of the first and second central processing units; a bus controller for providing control signals to the VME bus; and a control signal generator for generating control signals and enabling the second buffer through the input signals.

Title: Excretion treating method
Inventor: KIM DONG-HWAN
IPC: C02F11/00
Filed: 1992-09-08
Granted: 1993-03-06
Abstract: In the method, about 90 % liquid constituent of the  gathered excretion is separated, and the remaining excretion is supplied to a centrifugal separator so that it may enhance the general process efficiency of the centrifugal separator. The preprocessing  method comprises  a  first  step  of  filtering  miscellaneous   material included in the gathered excretion by dewatering  and  compressing it; a second  step  of  separating  liquid  constituent  from  the filtered excretion in a  liquid  cyclone,  forwarding  the  liquid constituent  to  a  main  processing  step,  and   the   remaining constituent to the centrifugal separator; a third step of  sending the light liquid and the fine solids to the main processing step.
