Patent KR-880000993-B1 (KR)
Title: Rome use method for a fixed pattern
Inventor: AN IL-SUNG
IPC: G06F3/153
Filed: 1985-03-25
Granted: 1988-06-10
Abstract: A method for using fixed pattern ROM which can indicate the arbitrary pattern and the color image signal on the monitor.  The pattern ROM (1) is connected directly to the address bus of a CRT controller and the pattern data bus is connected to shift register (2).  The one bit line (CD1) out of the pattern data outputs is connected to the ground bus of multiplexer (10).  When the character RAM(3) and the color RAM (4) are written, the bus controller (16) and the latch (9) are blocked by one control line of microprocessor (2).  Therefore the data line of character RAM (3) and latch (9) are blocked and the pattern data is output.

Abstract: A method for preparing diagnostic polystyrene bead comprises: (a) mixing human immunoglobulin G, carbonate-bicarbonate buffer solutions and 0.8-1.0 wt.% polystyrene latex bead; (b) reacting the mixt. at 37 deg.C for 90 min.; (c) centrifuging it to obtain the precipitated material; and (d) forming latex bead adsorbed with human immunoglobulin G. The latex bead is useful as diagnostic reagent for detecting rheumatoid factor.
