Introduction
- In chronic
fatigue syndrome (CFS), the level of acetyl carnitine in blood serum is
- decreased and
PET analysis shows that the uptake of acetyl carnitine into the brain is
- also
decreased. Doses of acetyl carnitine contribute to the recovery from
CFS. For
- elucidation
clinical condition of CFS and development of a medical cure, Dr. MIWA's
- research
group at Hokkaido University studied complementary DNA (cDNA) cloning of
- acetyl
carnitine transporters and measures to improve the transport activity.

Schottky Barrier MOSFETs as Resonant Tunneling Devices (Toshiba)
-
- Introduction
- Resonant
tunneling (RT) devices can single-handedly exhibit negative differential
- resistance.
RT devices are attractive for application in high-frequency signal
generation
- and
high-speed signal processing, without increasing circuit area. The
leading players in
- materials for
RT devices have been III-V compound semiconductors such as GaAs and
- InP. Single
or multiple quantum wells fabricated by Toshiba
-
- have produced
a large
- variety of RT
devices. In addition, it is theoretically suggested that a tiny carbon
- nanotube
(CNT) junction device can also exhibit negative differential resistance.
- However, in
terms of easy fabrication and simple integration, silicon-based
"monolithic"
- RT devices
are more suitable for existing large-scale integration (LSI) technology.
In this
- simulation
study, the researchers demonstrated a scaled Schottky barrier
metal-oxide
- semiconductor
field-effect transistor (MOSFET).
-
-
- Summary
- Schottky
barrier MOSFETs in the nanometer regime are being numerically studied.
The
- appearance of
the negative differential resistance due to resonant tunneling effect is
- confirmed by
non-equilibrium Green's function (NEGF) simulation. Designing the B of
- metal/silicide materials for source/drain, the Si film
thickness, and the applied voltage
- ranges,
scaled Schottky barrier transistors (SBTs) could be utilized as resonant
tunneling
- devices
compatible with existing LSI technology.

- Background
on Image Sensors
-
- An image
sensor is a device that detects an object's shape by means of a lens and
- converts the
analog signal to an electric image signal; it is the core component of
digital
- device
modules such as digital cameras.
-
- The image
sensors currently on the market can be divided into two categories: 1)
area
- image
sensors, and 2) linear image sensors. The area image sensor is a core
technical
- product that
currently leads the image sensor market, and it is used in digital
cameras,
- camera
phones, monitoring/security cameras, digital camcorders, personal
digital
- assistants
(PDAs), personal computer (PC) cameras, and optical mouses. In
particular,
- digital
cameras, camera phones, digital camcorders, and monitoring/security
cameras
- are the most
popular in the market. It is expected that in the near future, the
- application
of area image sensors will be extended to medical endoscopes, ground
- vehicle
cameras, and biometrics cameras.
-
- The linear
image sensor is primarily used in office scanning devices or barcode
reader
- devices. The
market is already inundated with these devices; hence, the business
cycle
- is going
down.

HORI at Himeji Dokkyo University in Japan is currently conducting
research on
- human
physiologic reactions to physical exercise.
- Under
comfortable ambient conditions (18-28 ), the human body can maintain a
- constant
temperature; physical exercise under the same conditions burns more
calories,
- which
increases body temperature. Under fully clothed resting conditions, the
heat
- discharged
from clothing is estimated to be 0.18 /kcal/m
- 2
- /h (1 clo
unit). At lower
- temperatures,
the value of clo increases, and at increased exercise intensity the
value of
- clo decreases
due to enhanced metabolism} Figure 1 below illustrates the relationship
- between
ambient temperature and clothing insulation under various metabolic
rates.

Introduction
- NTT is
studying an energy harvesting technology of which target is a power
source for
- sensor-networked society where a large number of small
electric appliances are needed
- as sensor
nodes. NTT proposed to integrate thermal and vibrational energy
conversion
- techniques
monolithically on a Si substrate using MEMS technology. Figure 1 below
- shows an
integrated power generator with thermoelectric and vibrational devices.
In
- order to
integrate these two types of devices, a capacitive type of vibrational
device was
- selected
rather than a piezoelectric type, because the latter requires special
materials
- and
complicated fabrication processes for integration. The thermoelectric
device as a
- power supply
and vibrational device as a variable capacitor can generate and boost an
- electrical
voltage with appropriate switching.

- 1. Summary
of Previous Update
-
- It has been a
busy year for the Next Generation Supercomputer Project
- (NGSP). Due to
some of the changes that have recently occurred, ATIP has
- decided to put
together a review "Kei-soku" UpdateTM in order to create a
- single
document that will give you, the reader, a complete understanding of
- the current
status of the NGSP.
-
- To begin,
since April 2006, Japan's Ministry of Education, Culture, Sports,
- Science and
Technology (MEXT) has been funding the NGSP under a five-
- plus-two-year
project entitled "Development and Applications of Advanced,
- High-performance Supercomputer Project." The Institute of
Physical and
- Chemical
Research (RIKEN), an Independent Administrative Agency (IAA)
- formerly under
MEXT, is managing the project and Dr. Tadashi WATANABE,
- formerly of
NEC and lead designer of their SX-series of supercomputers, is
- the current
project leader.
-
- Last year, the
budget for the NGSP was JPY 3.547 billion and this year, the
- government
allocated JPY 7.736 billion to the NGSP. These allocations include
- funding for
Japan's National Research Grid Initiative (NAREGI) project
- (approximately JPY 1 to 1.5 billion per year). However, these

Introduction
- Organic
Electroluminescent (OEL) device technology, also known as Organic Light
- Emitting
Device (OLED) technology, features characteristics such as a submicron-
- scale
emission layer, low power requirements, wide viewing angle, high
contrast
- ratio, and
rapid response.
-
- In 1997,
Pioneer Corporation put the first OEL display on the market, which was
- passively
driven and displayed a single green color; this type of OEL has been
used
- for
automobile audio and cellular phone displays.
-
- In 2003, SK
Display (a joint venture company of KODAK and Sanyo Electric Co.)
- commercialized a display for digital cameras, and Pioneer
commercialized a sub-
- display for
cellular phones by applying a red phosphorescent emission element.
- Both of these
types of displays are actively driven utilizing thin-film silicon
transistors.
- Consumer
products in which this display technology has been applied could be
- referred to
as second-generation (2G) devices.
-
- It is
expected that flexible OLEDs, a third-generation (3G) display
technology, will be
- commercialized in the very near future. Presently, there have
been various types of
- self-radiation of organic light-emitting transistors (OLETs)
reported. OLETs are

- Last fall,
Japan joined the "innovation" policy bandwagon by announcing the
- "Innovation
25" project. The project, which is tasked with creating a policy
- roadmap for
Japan that will lead to a broad-reaching and transformational
- change in the
economic life of the country by 2025, has as one of its largest
- supporters in
Dr. Kiyoshi KUROKAWA, who is the chairperson of Japan's seven-
- member
"Innovation 25 Strategy Council" as well as Prime Minister's ABE's
- Science
Advisor. Brought out of retirement last year by Prime Minster ABE, Dr.
- KUROKAWA has
spearheaded the effort in drafting an initial, interim, plan
- outlining the
project's strategy for increasing innovation in Japan; the final plan,
- after final
comments are gathered and incorporated, will be released in late May,
- 2007.
-
- What exactly
is the Japanese government trying to create with this project? As
- the official
"Innovation 25" website defines it, innovation currently means
- "technological renovation and management reorganization" or
simply "renovation
- or renewal."
However, the "Innovation 25" project also stresses a meaning of
- innovation
that is "using new technology and ways of thinking in existing

Introduction
-
- Professor
YOSHIKAWA of Kyoto University is conducting research on an inertial
- electrostatic
confinement fusion neutron source based on a Deuterium-Deuterium
- reaction.
According YOSHIKAWA, the advantages of this generator are its
portability
- and safety.
Typical neutron generators use radioactive elements, such as Tritium or
- Californium,
which, according to the professor, are hazardous materials. At present,
- the
application target is a mine detection device for plastic-type mines.
-
-
- Future
development targets include full-sized explosives detection devices for
- containers,
and explosives alert devices at airports. Conventional mine detectors
- based on
radar cannot detect plastic explosives, and mine disposal vehicles that
- induce mine
explosion are not suitable for anti-tank/anti-combat vehicle mines,
since
- their
explosions are much too powerful.
-
-
- A particular
detector system being researched YOSHIKAWA's colleague, Professor
- SHIROTANI at
Kyoto University, is based on monitoring hydrogen neutron scattering,
- which
detects the presence of explosives, and ray radiation emissions varying
by
- Nitrogen/Hydrogen ratio in the explosives, which determines
the type of explosives
