合成ダイヤモンドの工業利用 Industrial Applications of Synthetic Diamond Products |
鈴木数夫 Kazuo SUZUKI |
This paper describes the applications of
synthetic diamond products, which accounted
for more than 97 % of the world's annual
consumption of diamond in technical
sectors
for 1992. They have provided a wide,
and
may probably provide a wider range
of applications
due to their mechanical properties
properly
controlled by process parameters, as
well
as the surface modification techniques
which
have been developed remarkably in these
years.

cBN焼結体工具の切削加工用途への適用 Application of Polycrystalline Cubic Boron Nitride for Cutting Tools |
中井哲男 Tetsuo NAKAI |
Polycrystalline cubic boron nitride (pcBN)
materials, which are produced by sintering
cBN powder and binder material under ultra-high
pressure and temperature conditions, have
so high hardness, high thermal conductivity
and very weak affinity for ferrous metals
that pcBN has been used for cutting ferrous
metals such as hardened steel, cast iron,
powder metal heat resisting alloy or roll.
In order to improve machining efficiency
or accuracy, hard turning by pcBN material
has been introduced instead of grinding process.
High-speed cutting cast iron with pcBN material
is one of the most important applications
to reduce the production cost. pcBN also
shows more excellent cutting performance
than other tool materials for powder metal,
heat resisting alloy and roll. This paper
describes the characteristics and the application
examples of pcBN materials. [polycrystalline cubic boron nitride, hardened steel, cast iron, powder metal] |

大腸菌と酵母の圧力応答 −非致死高圧力領域における挙動− Response of Escherichia Coli and Yeast to Pressure: Their behaviors under Nonlethal High Pressure Conditions |
田村勝弘 Katsuhiro TAMURA |
Recent studies on behaviors of Escherichia coli and yeast at 10 - 40 MPa where these microorganisms
can survive were summarized. The aspects
covered are, 1) abnormal elongation of Escherichia coli cell by application of high pressure, 2)
correlation between hydrophobicity of the
cell surface of E. coli and drug susceptibility under high pressure,
3) stress response of yeast (induction of
various tolerance by heat shock and drug
shock in yeast) , and 4) pressure reversal
of alcohol effects on the growth of yeast
and its application to alcoholic fermentation
under high pressure. [ Pressure response, E. coli, Yeast, Hydrophobicity, Alcoholic fermentation,Drug susceptibility, Heat shock ] |

超臨界水による石炭および重質原油の分解処理 Decomposition Treatment of Coal and Other Heavy Fossil Fuels in Supercritical Water |
守谷武彦1 木下睦2 榎本兵治2 Takehiko MORIYA Atushi KISHITA Heiji ENOMOTO |
The property of its supercritical water can
be changed remarkably by controlling
its
temperature and density. Application
of its
characteristics may make possible the
decomposition,
liquefaction and/or alteration of coal
and
other heavy fossil fuels, and the removal
of sulfur, nitrogen, heavy metals and
so
on. In this report, decomposition treatments
for liquefaction of coal in supercritical
water are reviewed. Result of other
fossil
fuels such as oil sands are also presented. [Supercritical Water, Supercritical gas extraction, Water, Hydrothermal reaction, Coal, Liquefaction of coal, Oil sand, Bitumens, Shale oil] |

Expanded Fluid Alkali Metals |
Friendrich Hensel and Georg-Friendrich Hohl |
Fluid alkali metals are typical examples
of materials whose electronic structures
depend strongly on the thermodynamic state
of the system. The most striking manifestation
of this state dependence is the metal-nonmetal
transition which occurs when the dense liquid
evaporates to the dilute vapour or when the
fluid is expanded by heating to its liquid-vapour
critical point. The paper discusses equation of state data, electrical, and optical properties, and neutron scattering measurements of S(Q) and S(Q,ω) with special emphasis on the change in these properties in the metal-nonmetal transition region. The shape of S(Q,ω) change considerably on approaching the transition from the high-density liquid side, indicating a change in the interparticle interaction and the molecular structure. S(Q,ω) of rubidium in the density range between the melting point density and three times the critical density is characterized by the existence of well defined acoustic-phonon-like collective density excitations at high momentum transfer, whereas S(Q,ω) at a density of about twice the critical density is consistent with excitations of an optic-type mode in which two species tend to move in opposite directions.

日本の衝撃超圧力研究の歴史 -重点領域研究を通じて考えたこと- Recent Activities on Very High Pressure Research Utilizing Shock Waves in Japan |
澤岡 昭 Akira SAWAOKA |
Recently shock compression technology has been becoming popular in the field of materials science and geophysics in Japan as a tool of high pressure generation. A project research "Understandings of Shock Wave Phenomena" supported by Grant-in-Aid for Scientific Research of Ministry of Education, Science and Culture, Japan has been conducted in 1990-93. An important topic of this project was shock wave phenomena in condensed matters. A recent activity of the research on condensed matters is summarized and an importance of quantitative research of shock temperature in porous materials is emphasized. |
