9972 Minoruoda           Discovered 1993 May 26 by S. Otomo at Kiyosato.
Minoru Oda (1923-2001) was a cosmic-ray physicist, who started to work in x-ray astronomy when he was invited by Rossi to Massachusetts. He invented the "bamboo collimator" to determine more accurate positions of x-ray sources. He was director general of the Institute of Space and Astronautical Science during 1984-1988.
