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
  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)  2002 KSME Board Members ratified in the 2001 Regular General Meeting

  The 2001 Regular General Assembly of KSME was held at Chonbuk National
University Culture Center on November 2 last year on the occasion of
KSME Annual Fall Conference which was held at Chonbuk National
University on November 1 - 3, 2001. The Assembly was attended by 459
KSME Members (including 273 who entrusted their votes) and ratified 2002
KSME Board Members who were elected at the Board of Representatives
which was held at Korea Science and Engineering Building on September
21, 2001. As usual, only the new President and five Vice-Presidents were
elected by vote and the election of the Directors was left to the group
of former Presidents, newly elected President and Vice-Presidents. The
names of new KSME Board Members are as follows:

  President : Han, Dong-Chul (Seoul National University)

  Vice-Presidents : Kang Yong Lee (Yonsei University), Jung Yul Yoo
(Seoul National University), Jung Kyu Kim (Hanyang University), Jae Hak
Kim (Doosan Heavy Industries & Construction Co., Ltd.), In Kee Chung
(Yeungnam University).

  Directors :
  General Affairs : Jae Kyoo Lim (Chonbuk National University), Hong-Sun
Ryou (Chung-Ang University), Chong Nam Chu (Seoul National University).
  Treasury : Kwang Min Chun (Yonsei University), Gil-Moon Park (Chosun
  Activities : Sang-Hoon Choi (Konkuk University), Ji Oh Song (Samsung
Electronics Co., Ltd.), Jae Do Kwon (Yeungnam University), Wan Suk Yoo
(Pusan National University).
  Publications : Kwang-Joon Kim (Korea Advanced Institute of Science and
Technology), Tai Hun Kwon (Pohang University of Science and Technology),
Seyoung Im (Korea Advanced Institute of Science and Technology), Kwan
Soo Lee (Hanyang University) Simsoo Park (Korea University).


(2)  Large Output and Low Noise Motor for Electrical Power Steering

  Recently, EPS (Electrical Power Steering) is being widely applied in
order to reduce fuel consumption. The EPS applied car size is enlarged
from micro-cars in Japan to 2-liter class vehicle, and the output of EPS
motor is required to be large but the noise of it to be low.
  2-pole and 2-brush were used in conventional motor for micro-cars. But
4-pole and 4-brush have advantages for enhancing the output, because the
magnetic pass becomes compact, winding length becomes short, and brush
becomes small. By using 4-pole and 4-brush motor, we realized 500W
output, which was two times as large as 2-pole and 2-brush motor.
However, the difference of commutation timing in two brushes of same
polar causes the radial magnetic pull and the noise.
  We applied the short-circuit wires for symmetrical segments in
commutator. These wires keep the voltage of segments in the same plolar
being same, and the current distribution of armature being symmetrical.
Also these wires are easy to be implemented without increasing the motor
size. As a result, magnetic pull in radial direction was eliminated and
low noise level of 40dB(A) was realized even for 2-liter class vehicle.

(3)  Development of High Power MACH-30G Gas Engine

  Mitsubishi Heavy Industries,Ltd.(MHI) has developed a micro pilot
MACH30G gas engine ignited not by spark plugs but by gas oil less than
1% of total fuel energy. Brake mean effective pressure (BMEP) was
increased to 1.96Mpa, which covers output from 3.7MW to 5.8MW with V-12,
14, 16,and 18 cylinder configuration. This engine has been tested with
the common rail system for pilot injection, the VG turbocharger for air
/ fuel ratio control, and knock detection and control system smooth
operation. In this test, MHI achieved high thermal efficiency of 43.8%
and low NOx emission of 0.5g/kWh.

(4)  Processing of PCB  --New Technology of a Japanese Company

  Tokyo Electric Power Company (TEPCO) established one continuous
processing system of PCB (Polychlorinated Biphenyl) from de-toxifying to
re-utilization. Although its production and use was banned 30 years ago,
the PCB is still kept by the users as wastes. TEPCO pioneered this new
processing system with assured safety at its recycling center. This
system is catching attention of local governments and companies which
have long awaited for solution of the problem with PCB wastes.
