It appears that the negative response to their earlier publication has not
stopped that one Japanese group from continuing to look for unexplained
inertia effects in gyroscopes. See below.
The journal "Speculations in Science and Technology" mentioned below
sounds interesting. Has anyone here seen it? When reviewers for the
bigger journals reject papers having unconventional results, those types
of papers become concentrated in smaller more speculative journals...
which are usually great fun to read! The Journal of Scientific
Exploration (www.jse.com) is one such. I didn't find SST journal on the
web, except under www.tomson.com publishers ($130/yr personal
subscription, yikes!)

In the London Sunday Telegraph of 21 Sept. 1997, Robert Matthews
reports that a team of Japanese scientists have spun up a gyroscope
to 18000 rpm and dropped it through a distance of 63 inches in vacuo.
The time taken to fall this distance was 1/25000 sec. longer than when
the gyroscope was not spinning, corresponding to a weight reduction of
1 part in 7000. The effect only occurred when the gyroscope was
spinning anticlockwise. The fall was timed using laser beams.
The team say that this is in line with earlier findings of theirs published
in 1989.
This work was done by Hideo Hayasaka and colleagues at the Faculty
of Engineering, Tohoku University, Japan, together with Matsushita the
Japanese multinational. Their results are reported in the journal
Speculations in Science and Technology.
