Shanghai -- Fang Chun-hsifl (1), an instructor
(ndiexpe ue Ta-hsueh) (2), Shanghai, effici' ;: X-ray tubes, but also high-
and experiments, in producing not only
vacuum ore1//2 ofcone-millionth millimeter of mercury. In aT.ressedofathis
ment, the Board of Education of the East China regional government together
with a number of Shanghai business firms dealing in scientific equipment have further st made available nd a considerable sum whichn will manufacture hy igh_vacuumi
electriononic and also t to equip a aratus for
electronic tubes and X-ray tubes. An elect8V8ilablepeTThedvacuum pump used
fusing and sealing vacuum tubes is already phy by Fang until now one which thhas at its, lyingeubeforenused beginningiof thesSino-
laboratory for about ut 15 years,
Japanese war.
The work which resulted in this achievement was stimulated
theepatriotic
resolve to liberate China from the effect of the US embargo against
to China of articles that are of scientific and military importance. The tubes
Fang has made may be used not only for theoretical demonstration purposes, .)ut
they also have great practical value in scientific techniques and in national
defense. Besides his work on vacuum tubes, Fang is also engaged in work on
making Geiger counters, which are so important in connection with a certain
special branch of mining.
Fang, born about 1921, was a science student in Central University, Nanking
at the time of the Japanese invasion in 1937. During the war, he served for
about a year, in 1944, as an interpreter for US troops at K'un-ming, with whom
he became involved in discord, and left. In 1946, he took up scientific work
in the Communications University.
