Abstract
Improvements to the cryogenic current comparator and other aspects of the resistance measurement system at Gakushuin University have led to a new determination of the quantized Hall resistance in terms of /spl Omega//sub NML/ with reduced uncertainties. This determination leads to the result R/sub H/(GU 1992)=(1+0.008(33)/spl times/10/sup -6/)R/sub K/.<>
