(3) Ball SAW Sensor (Source: JSME)

@@Noritaka NAKASO (Dr.)
    Toppan Printing Co., Ltd.

 We have developed ball SAW (Surface Acoustic Wave) sensors, in which
SAWs, activated by an interdigital electrode on a piezoelectric solid
ball, propagate along the great circle without spreading beams due to
the diffraction. Its long propagation path of the SAW enables precise
measurements of the velocity. This depends on the condition of the ball
surface. For the application of the ball SAW sensor to industries, we
propose a hydrogen sensor for fuel cell that provides quick response
time of 10 seconds, wide measurable range from 0.05% to 100% and cost-
effectiveness. Pd thin film of 20 nm thickness deposited on a quartz
ball is used as a reactor, whose elastic property changes as a function
of hydrogen concentration. We have demonstrated its high potential for
sensoring hydrogen. Using a hundred small balls (1mm in diameter), it
is possible to build up a ball SAW array sensor. Other applications of
such ball SAW devices, with various reactive thin films, are a protein
chip, a smell sensor, a tactile sensor, etc. We believe that ball SAW
sensors will be used widely in many industries.


(4) Development of Medical Device for HMS/DDS (Source: JSME)

 Our Bio-Venture Center in the Osaka Institute of Technology is
developing a medical device, which is utilized for human being's health
monitoring system (HMS) and drug delivery system (DDS). It does this by
extracting the blood and detecting the indication of diseases, such as
diabetes, brain infarctions, heart attacks and gout, and injecting drugs,
such as insulin. This preventive medical system will be strongly
required in Japanese society, which is composed largely of elderly
 Our medical device consists of: (1)a micro piezoelectric pumping system
for blood extraction, (2)a bio-sensor for detecting Glucose, Cholesterol,
and Urea by using Glucoseoxidase (GOD), Cholesteroloxidase and Urease -
enzyme-, and evaluating concentration of glucose, cholesterol and urea
with high accuracy, (3)an IC chip for controlling actuators for blood
extraction and DDS injection systems, data processing and transmitter.
We have adopted Lead Zirconate Titanate (PZT) actuator for a micro
pumping system. RF magnetron sputtering was introduced to fabricate PZT
piezoelectric thin films. Bimorph actuators can be built-up by combining
an invar thin film electrode.


(5) Very Low NOx Gas Fired Boiler (Source : JSME)

    Miura Co., Ltd.

 Our small type once-through boiler offers superior features of easy
handling and short start-up time. As a result, our boilers make up
more than 80% of the total domestic market share of evaporating quantity
general industrial boilers. Among them, a large proportion of operators
install and control multiple boilers in order to enhance operating
efficiency. Here, we introduce gas fired boilers specifically designed
for multiple installations providing advantages in the reduction of
environmental loads (low NOx, low CO), space-savings and low air
combustion, in addition to the short start-up time and ease in handling.
 More than 6,000 units of this boiler type have been ordered over ten
some years from launch, and now, this boiler has been redesigned under
a concept of further reduction in environmental load (very low NOx) and
the pursuit of safety.
 The small type once-through boiler has rapidly spread due to its easy
handling, high efficiency and labor-savings, however, from now, further
reductions in environmental loads and enhancements in safety will be
demanded. These demands have been taken into account in the model
changeover of the very low NOx gas fired boiler. This very low NOx gas
fired boiler will respond to the users' demands for a "Cleaner and more
reliable" boiler.

(6) Toward Large-Scale Integration of Carbon Nanotubes   (Source: KSME)

 Professor Junghoon Lee of Seoul National University (in the School of
Mechanical and Aerospace Engineering ) announced that they developed a
new large scale patterning method for carbon nanotubes. They reported
the method in the recent issue of Langmuir (vol.20, 2004). The paper
presents a large-scale assembly method to deposit discrete multiwalled
carbon nanotubes (MWCNTs) across gaps present in an electrode array.
A parametric study showed that MWCNTs dispersed in a liquid could be
deposited to individually span gaps by combining an alternating current
(ac) and a direct current (dc) electric field in a given ratio; it was
shown that the ac field (5 MHz) serves to selectively attract and the
dc field to guide individual deposition. Repeated trials demonstrated
accurate, discrete, and aligned deposition at room temperature with 90%
yield over an electrode array having 100 gaps. The yield of successful
deposition was around 90% at repeated trials. The developed
experimented method is scalable and can be extended to ultrahigh
density (nanoscale) deposition. Though the spacing that they used was
20 L, they said that it could be substantially reduced with other
nanoscale lithography or nanostamping/imprint methods. They claim that
it may become a method of choice for mass assembly of a variety of
nanostructures and nanoscale devices, for a variety of applications.
