Journal bearings, which are used in all kinds of rotating
machinery, do not only support static loads, such as the weight of
rotors and load caused by transmitted torque of reduction gears,
but are, in addition almost the only machine element that is able
to suppress various exciting forces acting on the rotating shaft.
As rotating machines have become large and multi-staged, while
compactness, high speed, and high output have also been realized in
recent years, not only has the bearing load increased, but also the
magnitude and variety of exciting forces. Therefore, the role and
importance of journal bearings have increased tremendous ly. In
particular, for the design of rotating machines with low vibration
levels and high reliability, knowledge of the exact characteristic
data of bearings, and especial ly of the stiffness or spring
coefficients and the damping coefficients of oil films in bearings,
is essential. However, the amount of reliable data now applicable
to practical design is limited. Through the activity of the
Research Subcommittee on Dynamic Charac teristics of Journal
Bearings and Their Applications (designated as PSC 28), estab
lished and organized in June 1979 through May 1982 within the Japan
Society of Mechanical Engineers (JSME), these coefficients,
together with static characteris tics, have been calculated and
also measured on a number of new test rigs.

It is a great challenge in chemistry to clarify every detail of
reaction processes. In older days chemists mixed starting materials
in a flask and took the resul tants out of it after a while,
leaving all the intermediate steps uncleared as a sort of black
box. One had to be content with only changing temperature and
pressure to accelerate or decelerate chemical reactions, and there
was almost no hope of initiating new reactions. However, a number
of new techniques and new methods have been introduced and have
provided us with a clue to the examination of the black box of
chemical reaction. Flash photolysis, which was invented in the
1950s, is such an example; this method has been combined with
high-resolution electronic spectroscopy with photographic recording
of the spectra to provide a large amount of precise and detailed
data on transient molecules which occur as intermediates during the
course of chemical reac tions. In 1960 a fundamentally new light
source was devised, i. e., the laser. When the present author and
coworkers started high-resolution spectroscopic stud ies of
transient molecules at a new research institute, the Institute for
Molecu lar Science in Okazaki in 1975, the time was right to
exploit this new light source and its microwave precursor in order
to shed light on the black box."
These stories were written primarily for my nephews and nieces and
other members of the family because they have no clue about what
our history and what had happen during the second world war. There
are 120,000 different stories from 120,000 of Japanese Americans
who were put in the concentration camp and my story is just one of
many. Many have suppressed the past and forgot about them. I feel
the story must be told. This is just my story and how I remembered
the past. Others have experienced a different life some good some
bad. My parents really had a positive outlook on life and that is
why I have no bitterness on what has happened plus I was a
pre-adolescent child who wanted to enjoy playing outdoors.
