About the Asian TOP Panel (ATOP)
    On August 29, 2001, presidents of four engineering societies gathered@
in Japan to pave the way for stepped-up collaboration.  They are Chinese
Mechanical Engineering Society, Institution of Engineers Indonesia,
Japan Society of Mechanical Engineers, and Korean Society of Mechanical
Engineers.
    They agreed to establish the Asian TOP Panel (ATOP), which is a@
voluntary body and open to any Asian engineering society and
institution. At the first meeting, they decided to issue monthly E-mail
newsletter which you are reading now. It will carry short technical news
of Asian countries, and be distributed to all individual members of the
ATOP societies and institutions.
    ATOP will meet every two years. The next meeting will be held in
Korea in 2003.

(1) Strong Market Demand for the Cars (Source : CMES)

 Strong market demand drove up the domestic auto output to a record
high last month, indicating that the country's auto capacity has
further improved.
 According to the National Bureau of Statistics, 427,600 cars were
produced in China last month, up 60,000 from August and an increase of
36.8 percent from a year before.
 Car output in September hit a monthly record high, exceeding 421,900
in March this year, the previous record-holder.
 Sedan output hit 191,300 in September, exceeding 190,000 for the first
time, up 21,900 from a month before and an increase of 69.7 percent
from the previous year.

(2) OTIS-LG to Make 340 Elevators for China (Source : CMES)

 OTIS-LG, a joint venture between the multinational elevator firm
OTIS and Korea's LG Group, has won an order to supply 340 elevators,
worth 9 million US dollars in total, to China.
The firm says the order is its largest to date.
 The elevators will be installed at office buildings to be built in
the Advanced Business Park in Beijing.
 OTIS-LG has supplied about 16 thousand elevators to China since it
first started doing business here in 1995.

(3) European Gas Heater Manufacturers Eye Chinese Market (Source : CMES)

 European manufacturers of individual gas heating systems are pinning
high hopes on the booming Chinese market as the country sees rapid
economic growth and greater awareness of environmental protection.
 China's ongoing project to build a 4,000-kilometer cross-country gas
pipeline has further encouraged European companies who have occupied 50
percent of the Chinese market in less than five years, defeating their
Republic of Korea rivals who entered China in the mid-1990s.
 A total of 120,000 individual gas heating systems are sold in China
annually, with sales of more than 600 million yuan (73 million US
dollars). Most are imported, but in recent years, Sino-foreign joint
ventures have begun to manufacture the heaters in China, while some
local companies are producing the products with foreign technology.
 Representatives from 12 European companies and Chinese experts and
officials attended the European Individual Gas Heating System
Symposium, which was sponsored by the Sino-French Professional
Training Center on Energy.
 The European companies are Ariston, C&M, Hermman, Aereco, Bosch,
De Dietrich, Immergas, Beritta, Buderus, Frisquet, Rettig, and Wilo.

(4) US Pump Firm Nears Acquisition Deal in Shanghai (Source : CMES)
 
 The United States-based company ITT Industries Inc., the world's
largest provider of pumps and fluid technology systems and services,
said in Shanghai on Oct.22 it is close to acquiring a local private
waste-water treatment company.
 The details will not be announced until November, but the
acquisition is regarded as testimony to the company's future strategy
in China, involving more acquisitions in the coming years.
 Mark Steele, president of the ITT Industries (China) Investment
Co. Ltd., said: "We have high aspirations for our business in China,
especially in the water and waste-water area. "We hold these
expectations because China is the fastest-growing market for us, and
we see huge opportunities here." ITT has so far set up 10
manufacturing facilities around China, involving combined investment
of more than US$100 million.
 Three of the facilities are engaged in the fluid technology business,
involving the production of pump systems and related equipment for
water management and waste-water treatment. The rest are in the
electronic components business.
 Water-related businesses are expected to be a high-growth area for
future ITT operations in China.
 Pumps produced by ITT operations in China have been widely used in
projects such as the Three Gorges Dam project, the Xiaolangdi
Reservoir project on the Yellow River, and the Suzhou Creek
rehabilitation project in Shanghai, the company said. The pumps
involve brands such as Flygt, Goulds, Lowara and Sanitaire.
 According to Steele, top ITT officials have held initial yet
"constructive" discussions with water authorities under the State
Council regarding the company's involvement in China's ongoing
massive south-to-north water diversion project, which involves total
investment of over US$60 billion.

(5) Development of Micro Shape Machining Technologies (Source : JSME)

 Micro mechanical devices and these applications have been increasing.
The micro electro-discharge machining (EDM) and the micro grinding
technologies applied to those devices are introduced.
 The micro EDM has achieved to bore micro holes as small as 5 micron
diameter by minimizing discharge energy less than 10-7J. The deviation
of the diameter in the case of 20 micron diameter holes into the
stainless steel plate is less than 0.3 micron. By using a brass plate
electrode which has several micro holes, a block workpiece can be
plunged to micro pin array at the same time corresponding to the
micro holes on the brass plate.
 Micro optical devices are required around 0.1 micron profile accuracy
and less than 20 nm surface roughness, so the micro grinding
technology has been developed. The micro EDM process on the machine
can true the micro size grinding tool made of polycrystalline diamond.
A micro cylindrical lens that has 150 micron radius and 1 mm length is
finished with the micro grinding method in the above accuracy and
surface roughness.
 To accomplish higher accuracy and more complex shape machining,
applications of micro shape machining technologies will be increased
in the future.

 Experimental studies of liquid atomization and spray have contributed
to designing fuel injectors of jet and IC engines. However, the
phenomena are still not very well understood because they are very
complicated multiphase fluid motions occurring in a very tiny area.
Due to the recent development of digital computers, highly complicated
and large scale numerical simulations for multiphase flows are getting
affordable. Accordingly, we have established a numerical code for
simulating gas-liquid two-phase flows. The numerical scheme used for
tracking the gas-liquid interface is the level set method. Some recent
our results of numerical simulations related to fuel injection and the
subsequent droplet motions are introduced. The example case of liquid
jet breakup simulation which is relevant to pre-mixed fuel injection
is at Re=15000, We=10000 and the liquid-gas density ratio of 800. The
results of the binary droplet collision simulation of the off-center
separation with satellite droplets are also shown. We believe that
such a simulation is a powerful tool for understanding the phenomena
and designing fuel injection systems in the near future.

(7) Manual regeneration type DPF (Source : JSME)

 The Environment Security Ordinance will be effective from October,
2003 in the Tokyo Metropolitan area and three prefectures. The vehicles
with diesel engine which don't meet the standard of PM (particulate
matter) emission will be prohibited to run in these areas without DPF
(Diesel Particulate Filter) by this regulation. Types of DPF are
classified into automatic regeneration DPF such as intermittent
collection-regeneration type and continuous collection-regeneration
type and manual regeneration DPF. Though automatic type DPF collects
PM automatically, the system of intermittent collection-regeneration
type is too complicated and continuous collection-regeneration type
can be regenerated on the condition of above 250-300 degrees C.
emission gas temperature. The manual type DPF is suitable for vehicles
of shorter distance and/or lower speed operation in urban area though
filter regeneration is done manually. Also, this type DPF is
recognized as the necessary system for in-use vehicle with diesel
engine.
