(1) Firm Transforms to JV (Source: CMES)

Shanghai Electric Group Co Ltd, a joint venture between three
state-owned companies and three domestic private firms, was set up in
Shanghai on Mar.2, a move which signals a breakthrough for China's
biggest machinery equipment maker and the reform of state-owned assets.
The 9.01 billion yuan (US$1.086 billion) company next aims to attract
foreign investment and is also expected to sell shares later in Hong
Kong.
However, Zhu Mingqi, a spokesman for its parent, Shanghai Electric
(Group) Corp, told Shanghai Daily that no specific timetable has been
set for the foreign investment and to sell shares.
The new company takes over the SEC's three listed companies, Shanghai
Electric Co Ltd, Shanghai Diesel Engine Co Ltd and Shanghai Electrical
Apparatus Co, while their business will remain the same.

(2) New Standard in Effect (Source: CMES)

A new national standard on washing machines was put into effect this
month which ranks the products according to six criteria including
energy-saving, water conservation, noise reduction, moisture content
and life-span.
Whirlpool Home Appliance (Shanghai) Co Ltd recently obtained the
first quality certificate, issued by the National Household Electrical
Appliances Standardization Technical Committee.

(3) Sales Boost for China's Machine Tool Makers (Source: CMES)

The rapid growth of machine tool sales in China is giving Chinese
manufacturers a strong platform from which to compete with established
western and Japanese suppliers.
Last year, sales of machine tools in China totalled six and a half
billion US dollars making it easily the world's biggest market. Germany
was in second place, with purchases worth four and a half billion
dollars.
The strong sales of machine tools have boosted the rapid development
of Chinese manufacturing.
But much of the growth is fuelled by western and Japanese
multinationals setting up factories to take advantage of cheap labour
and good sales prospects in Asia.

(4) Trane Opens R&D Centre in Shanghai (Source: CMES)

Teling Manufacturing (Trane), one of the three major branches of
American Standard Companies Inc, a Fortune 500 enterprise, launched
its research and development (R&D) centre on February 16 in Shanghai
and is to set up its Asia-Pacific headquarters in the booming city.
With US$1.5 million invested, the R&D centre will employ 100 people
by the end of 2004 and will initially concentrate on commercial
heating, ventilation and air conditioning products sold under the
Trane brand.
In addition to developing products for customers in China, the
centre will qualify Chinese manufacturers as suppliers of materials
and component parts for use within the production processes at
American Standard Companies' manufacturing facilities around the
world.
Trane will invest more than US$10 million over the next three years
to develop new products and technologies for the Chinese market. This
is in addition to the US$181 million in capital and equity investment
that American Standard Companies has placed in its China operations
through 2003.

(5) Materialization of Ultra Compact and Thin Module Using Compression
    Type Flipchip Technology (Source : JSME)

    Kazuto Nishida
    Matushita Electric Industrial Co.,LTD.

We have developed a new flip-chip process called NSD (Non-Conductive
Adhesive Stud-Bump Direct Interconnection). First, a resin encapsulation
sheet is attached to the substrate by heat compression. Stud-bumps are
formed on an IC chip by means of conventional wire-bonding technology.
The chip is then attached to the substrate. Finally, the encapsulation
film is heated and compressed using a heating tool, during which the
stud-bumps contact the electrodes on the substrate to form electrical
interconnections that follow any warp in the substrate. When the
encapsulation film cools, a compression force is generated between the
IC chip and substrate, thus maintaining the interconnections.
We have developed high-density modules using thin IC and thin
substrate. They were bonded by the compression type flip chip
technology (NSD method). Both sides flip chip solved the problem of
the warp. The high capacity memory card of 512MB was put to practical
use by applying these results. This achieved four times the Si density
compared with conventional module.

(6) Cavitation Shotless Peening (Source: JSME)

Cavitation normally causes severe damage in hydraulic machineries.
However, cavitation impact can be used for surface enhancement of
metallic materials in the same way as shot peening. In case of peening
by cavitation impacts, shots are not required, thus the peening using
cavitation impact is called "cavitation shotless peening (CSP)". The
advantage of CSP is that the peened surface is less rough compared
with shot peening, since there are no solid body collisions involved.
In CSP, cavitation was produced by injecting a high-speed water into
water, i.e., a cavitating jet. Recently, the author succeeded to
produce a cavitating jet in air by injecting a high-speed water jet
into a low-speed water jet, which was injected into air, using a
concentric nozzle. Author has revealed that the cavitating jet in air
is most powerful compared with normal water jet and cavitating jet in
water. Author already succeeded to improve fatigue strength of
metallic materials and to peen forming.

(7) An Introduction to Homogenization Method (Source: JSME)

    Masashi Aoki
    TOYODA GOSEI CO., LTD.

This book has been compiled by The Japan Society for Computational
Engineering and Science, and published by Maruzen CO., LTD. in 2003 for
engineer as a beginner's book of mathematical homogenization method.
After describing the concept of the homogenization method and the
essential features of homogenization and localization by means of a
simple one-dimensional structural problem, this book introduces
representative formulations for multi-dimensional linear elasticity
problem. The computer implementation of the finite element method for
homogenization and localization is explained in detail by FORTRAN
source codes, which is included in an attached CD-ROM. In addition to
the solid mechanics problems, the problems of heat conduction, flow in
porous media and beam bending come in scope of the book. In the final
part of the book, several numerical examples are presented, in which
the models derived from the homogenization method are examined and the
resulting numerical solutions are compared with the reference solutions.
In the case of homogenization with complicated microstructure, VOXEL
finite element method is also introduced along with a sample computer
program for steady state heat conduction problems. It can be recognized
that this book will be a good introductory textbook of the
homogenization method for engineers in various fields.

Pusan National University (Department of Aerospace Engineering,
Byung-Young Moon, Gyung-Ju Kang, Beom-Soo Kang) reported a new type of
bearing system, Elastomer Bearing System, through their publication in
KSME International Journal ( Vol.18, No.1, 2004). They described a
method for designing an elastomeric bearing system and carried out its
mechanical property analysis. Through experimental and theoretical
approach, they showed the validity of their bearing system with fiber
reinforcement. Several kinds of bearing systems in the form of long
strips are designed, fabricated and shown to be comparable to
steel-reinforced bearing.

An autonomous pipeline inspection gauge system has been developed for
determining position, orientation, curvature, and deformations such as
dents and wrinkles of operating pipelines by Korea Gas Company and
Seoul National University. This result was published in KSME
International Journal (Vol. 18, no.3, 2004 ). The most important part
of several subsystems is the Strapdown Inertial Measurement Unit (SIMU),
which is integrated with velocity and distance sensors, weld detection
system, and digital recording device. The Geometry Pipeline Inspection
Gauge (GeoPIG) is designed to operate continuously and autonomously
for a week or longer in operating gas pipelines. They provided the
experimental results for a 58 kilometer gas pipeline.
