UEC Museum of Communications
Sharing science and technology of the past for visions of the future
A walk through the UEC Museum of Communications is like walking through a three dimensional
encyclopedia of the history of cutting edge wireless communications technology including 'spark gap
transmitters'; 'Lieben Tube'; Fleming oscillation valve; photomultiplier tube used for neutrino detection at the
Kamiokande Observatory that led to the 2002 Noble Prize in Physics for Masatoshi Koshiba; and Japan's firstnuclear magnetic resonance system developed by UEC in 1950.
The exhibits at the Museum reflect the history of innovative research and development at UEC, Tokyo, thatwas founded in 1918 as the Technical Institute of Wireless Communications to educate and train radio
operators in recognition of the importance of radio communications following the Titanic disaster in 1912.
The Museum consists of seven exhibition rooms spread over two floors of a dedicated building at the center of
the UEC, Tokyo, campus in Chofu. Here are some of the most popular exhibits at the Museum.

Embossing Morse Telegraph System (Corridor)
Perhaps one of the most unusual exhibits is the replica of an Embossing Type Telegraph Key System or"Embossing Morse Telegraph" given by Commodore M.C. Perry as one of many presents to the
Tokugawa-Bakufu government in 1854. Notably, Commodore Perry's colleagues actually demonstrated thetelegraph system by transmitting messages in English, Dutch and Japanese across wires stretching about a'mile' near Yokohama bay.

Relay Computer AL-1 made by CASIO (Room 2)This pioneering "programmable relay calculator" was manufactured by Casio Computer Co. Ltd in 1962 andis internationally recognized as one of the major breakthroughs in modern computing. Underscoring theimportance, Japan's Center of the History of Japanese Industrial Technology officially registered it as 'Future
Technology Heritage' in 2014. Furthermore, the Information Processing Society of Japan has officiallycertified the Al-1 as an "information processing technology heritage".

Edison Phonograph (Room 2)This working exhibit is an Edison Phonograph Standard Model D made in 1911. It consists of a cylinder
record player driven by a spring and a sapphire needle that runs through a narrow groove on the cylinder
record resulting in sound that is amplified by the large speaker. There are two types of cylinder records: thewax version plays for two minutes and the Amberol type for four.
Thomas A. Edison invented the cylinder phonograph in 1877. He continued to improve the cylinder
phonograph until 1929 competing with the disc record invented by Emile Berliner in 1889.

Hallicrafters Model DD-1 Skyrider Diversity Receiver (Room 3)
The DD-1 diversity receiver that is enclosed in a single cabinet was produced in 1937-38 by the Hallicrafters
Company for 'diversity reception' that is effective in reducing fading signals in shortwave communication.
Notably, the DD-1 receiver on display at the UEC Museum is the only one in the world existing in complete
condition.

Recreation of a classroom for training wireless telegraph engineers (Room 5)
This room offers unique insights into vocational training facilities for radio engineers in Japan at the TechnicalInstitute of Wireless Communications, the forerunner of UEC. The desks and instruments on display wereactually used in 1960s. The front row near the instructor is the receiver's desk where trainees receives Morse
code via speakers and wrote it down by hand or typing. The rear side is the desk where trainees sent Morse
code. When a trainee is tapped keys according to a textbook, the codes were recorded on tape. Later, trainees
used the tape to check the results of their classwork.

Lieben Tube (Room 6)
The exhibit is a rare example of this famous tube that was invented in Austria about 100 years ago and usedby Germany in World War One for radio communications. The tube was produced by AEG-Telefunken and ison loan from Tekniska Museet Museum of Science and Technology, Stockholm, Sweden. The tube is a 'triode'filled with mercury vapor, measuring 30 cm long and 10 cm in diameter, with the two glass tubes joined at thecenter producing its unique shape.

Early development Fleming Valve (Room 6)
The Fleming Valve was invented by J.A. Fleming (UK) for use in a radio receiver.This one is believed to havebeen made around 1910 and is exhibited with other pioneering vacuum valves.

Nuclear Magnetic Resonance magnet (Room 7)
This MRI magnet was developed by UEC researchers in 1959 and was the first such unit in Japan. Thissystem became the prototype for the much advanced MRI systems used for medical care all over the world.
UEC researchers have also contributed to the development of electron spin resonance, laser spectroscopy,
kite-like antenna, and the understanding of the functions of the brain.

Nanoparticle-polymer composites boost holographic data prospects
Holograms offer a means of increasing data storage density that may help to meet the demands of everdecreasing device sizes and increasing memory requirements. Kohta Nagaya, Eiji Hata and Yasuo Tomita at
the University of Electro-Communications in Japan demonstrate that coaxial holographic digital data storage
in a thiol-ene based nanoparticle-polymer composite can achieve competitive symbol error rates andsignal-to-noise ratios.
Using changes in refractive index to optically record data, holograms record in three dimensions instead ofbeing limited to the surface alone, thereby increasing the amount of data recorded. To diminish symbol error
rates and increase signal-to-noise ratios the recording material must undergo large refractive index changes
with a high recording sensitivity and be resilient to shrinkage during the process.
Inorganic nanoparticle-polymer composites are excellent candidates for meeting holographic data storage
criteria, and the UEC researchers have already demonstrated holographic storage in nanoparticle-polymer
composites by use of thiol and ene-monomers, 'so-called thiol-ene monomers'. By shifting the storage medium
within a few tens of micron-size beam spot during the recording process holographic shift-multiplexing
storage was achieved.
Now the UEC researchers have demonstrated co-axial holographic data storage in thiol-ene based
nanoparticle-polymer composites. Coaxial data recording positions the reference beam around the signal beamand has been proposed as a means of increasing data density and transfer rates for a more competitive data
storage technology.
The researchers used silica nanoparticles uniformly dispersed to secondary thiol and an allyl triazine trienemonomer components. Optimum symbol error rates (less than 10-4) and signal-to-noise ratios (higher than 10)
were achieved when silica nanoparticles were used at 25 vol.% concentrations and the composition of
thiol-ene monomers was stoichiometric.
The researchers conclude, "These results show the usefulness of thiol-ene based nanoparticle-polymer
composites as coaxial holographic data storage media."

Relativistic effects pack a punch in high-temperature plasma collisions"The interaction of highly charged heavy ions with electrons is one of the most important atomic processes inhigh-temperature plasmas," explains University of Electro-Communications researcher Nobuyuki Nakamura
in his recent J Phys B topical review. These high-temperature plasmas occur in a surprisingly large range of
scenarios from astrophysical plasmas and solar corona, to fusion reactors and even laser-induced plasmas for
short wavelength nanoscale photolithography, raising the stakes for understanding their behaviour.
Nakamura's review summarises how the relativistic effects resulting in the "Breit interaction" can play asignificant role in these processes.
The Breit interaction introduced by G Breit in 1930 is the relativistic effect involved in interactions between
electrons. In many cases - such as the calculation of atomic energy levels - the correction to the standard
Coulomb interaction is small. The Breit correction remains small even for energy level calculations of heavyions, where atoms with a high mass are stripped of many of their electrons so that they are strongly charged.
However when a highly charged heavy ion resonantly captures an electron, the Breit interaction can become
dominant. This 'dielectric resonant recombination' process is accompanied by energy radiation for stabilisation,and is prevalent in high-temperature plasmas. The Breit interaction can enhance the resonance effects by afactor of two. As Nakamura points out in his review, the Breit interaction is also responsible for the strong
dependence on proton number observed in the experimental resonance strength, and helps to explain serious
discrepancies with existing theory observed in polarization measurements of resonance processes.

Spectrometry: Miniaturising near-infrared devices
The development of compact, handheld devices to measure spectra in the near-infrared (NIR) wavelength
range would have a wide range of applications, including medical diagnostics and self-monitoring of blood
glucose levels.
Many spectrometers are designed with gratings incorporated - this allows the device to detect different
wavelengths of incident light separately and provides a more detailed sample analysis. However,grating-based micro-spectrometers require an optical path of a certain length to ensure good resolution,
therefore placing limitations on shrinking the size of the device.
Now, Tetsuo Kan at the University of Electro-Communications in Tokyo and co-workers have developed amicro-spectrometer capable of detecting NIR spectra using a Schottky photodetector and a gold-based grating,the combination of which means a lengthy optical path is unnecessary.
Their design makes use of the phenomenon known as 'surface plasmon resonance' (SPR) - the oscillation ofelectrons on a surface where negative and positive permittivity materials meet, following stimulation by
incident light. The team placed the gold grating directly onto the surface of a photodetector made from asilicon substrate (see image). The photodetector uses the resulting SPR created on the surface of the gold togenerate a photocurrent.
When different wavelengths of light hit the device, the angle of the SPR changes. By converting the different
photocurrents back into their corresponding light wavelengths, the team could differentiate between different
wavelengths of light at high resolution. The new micro-spectrometer performed comparably to a commercial
spectrometer when tested with NIR light. Crucially, the design is also compatible with semiconductor
fabrication.

Hybrid rockets: Optimizing performance using design informatics
Single-stage sounding rockets are used to transport scientific equipment into, or just beyond, Earth's
atmosphere to measure phenomena such as aurora. Recently, scientists have begun designing rockets withhybrid engines, which work by alternating between different phases of solid fuel and liquid or gas oxidizers.
Hybrid rockets are cheaper, safer and cleaner than those with conventional solid fuel engines.
While hybrid rockets are still largely in the design and prototype phase, there has been considerable progressin the design technologies used to model and predict optimal rocket performance. Now, Kazuhisa Chiba at the
University of Electro-Communications in Tokyo, together with scientists across Japan, have demonstrated thepotential advantages of an 'extinction-reignition' protocol in hybrid rockets using a novel design informatics(DI) platform.
Computer-based DI allows researchers to investigate hybrid rocket advantages during concept design byillustrating many elements of the physics of rocket launch and flight in one 'bird's eye view' design space.
Chiba's team wished to determine whether firing the rocket engines more than once ('extinction-reignition')
was beneficial to the overall flight path stability, distance and duration of flight in the lower thermosphere.
The team ran the computer model thousands of times, each time tweaking different variables - such as
extinction time between first and second combustion - to determine the potential advantages of an
extinction-reignition protocol and the optimal rocket design. Their results indicate that, while downrange
distance was not extended, the time spent in the thermosphere was prolonged. Further exploration of the data
generated suggested a hypothesis to extend downrange in future.

Insights into the health of non-regular workers in Japan
Shinobu Tsurugano MD., PhD.
Associate Professor, Health Care Center, University of Electro-Communications, Tokyo.
Shinobu Tsurugano is the occupational health physician at the UEC Health Care Center responsible formonitoring the health of staff and students at UEC. Tsurugano graduated from Miyazaki Medical School in
Kyushu, and specializes in clinical psychosomatic medicine. Her research covers preventative and industrial
medicine with the current focus being the health of non-regular employees in Japan.
"The main aim of my current research activities is to increase the 'visibility' of the health conditions of
non-regular workers in Japan," says Tsurugano. "Namely, to clarify the effect of non-regular employment on
the health of employees in Japan, where according to government figures published in 2013, approximately
21 % of men and 55% of women were non-regular employees--that is not permanently employed." This
research is based on analysis of statistics published by government agencies including the Ministry of Health,Labour and Welfare.
Notable findings
Statistics up to 2010 for Japan show that approximately 52% of all researchers in academia are non-regular
employees including post-docs, fixed term contract researchers, and part-time lectures. "Analysis of a survey
by the Union of University part-time Lectures indicated even people with high academic qualifications felt
stress due to uncertainties about their future as non-regular university employees," explains Tsurugano.
Women working as part-timers were less affected by stress than men. "We think that this is because many of
the women choose to work part time or as non-regular workers, but men do not," says Tsurugano.
Tsurugano says the health of non-regular workers-both male and female-still requires much more research.
"My goal as a medical doctor specializing in industrial health and working in academia is to support scientists
and engineers cope with stress and other issues related with their working conditions."

Innovative molecular robotics: Chemical reaction circuits for intelligent
molecular robots
Satoshi Kobayashi Professor, Department of Communications Engineering and Informatics, Graduate Schoolof Informatics and Engineering
Satoshi Kobayashi is one of the key members of the interdisciplinary project, "Development of Molecular
Robots Equipped with Sensors and Intelligence", funded supported by Japan's Ministry of Education, Culture,
Sports, Science and Technology (MEXT). "Our goal is to develop functional molecular robots," says
Kobayashi. "These robots are autonomous and react to their surroundings via functional molecular devices
such sensors, actuators, and computers. My role in the project is to design molecular computer, that is logic
circuits, for constructing intelligent molecular robots."
Figure 1 shows the main features of the molecular computer being developed by Kobayashi and his colleagues
at UEC. Notably, DNA molecules carry out most the information processing and the main problem to resolve
is how to transform DNA molecules to the other molecules and vice versa.
Notably, Kobayashi has proposed implementing molecular robots using analog computing devices, amplifier,adder, multiplier, and divider that are time-responsive (Fig.2). "These devices can be implemented by using
simple reversible strand displacement reactions such as seesaw gates," says Kobayashi. "Under these
conditions, the computation is defined as being in steady state.""Molecular robots are expected to find a wide range of applications, including in medicine," says Kobayashi.
"In the future, we will need expertise in control theory and much faster molecular computing devices. The
ultimate challenge is developing ways of constructing an actual system composed of all the individual parts.
We still need many new ideas! "References

This is a unique workshop in terms of the interdisciplinary nature of the
topics presented. Specific areas covered were space plasma physics(ionosphere, magnetosphere, and aurora), atmospheric electricity(thunderstorm and lightning, and weather), seismo-electromagnetics,
electromagnetic compatibility, synthetic aperture radar, and astronomy.
The talks were united by Maxwell's equations describing
electromagnetic phenomena.

Prof. Gomes (Univ. of Putra, Malaysia)

There were 15 oral talks (15 minutes presentation and 5 minutes fordiscussion and questions) given during the workshop. The discussion
sessions after the talks were very active.
This workshop this year included the following talks during the newinternational sessions introduced for the first time.

1. J. B. Baker (Virginia Tech., USA / ISEE, Nagoya Univ.)

Dr. Ponomarenko (Univ. of
Saskatchewan, Canada / ISEE, Nagoya
Univ.)"Hemispheric observations of polar cap patches and the tongue of
ionization"
2. C. Gomes (Univ. of Putra, Malaysia)"Lightning sferics; HF to VHF frequency bands & broadband"
3. P. Ponomarenko (Univ. of Saskatchewan, Canada / ISEE, Nagoya Univ.)"Effects of ionospheric refractive index on

The University of Electro-Communications (UEC) in Tokyo
is a small, luminous university at the forefront of pure and applied sciences, engineering, andtechnology research. Its roots go back to the Technical Institute for Wireless Commutations,which was established in 1918 by the Wireless Association to train so-called wireless engineers
in maritime communications in response to the Titanic disaster in 1912. In 1949, the UEC wasestablished as a national university by the Japanese Ministry of Education, and moved in 1957
from Meguro to its current Chofu campus Tokyo.
With approximately 4,000 students and 350 faculty, UEC is regarded as a small university, butwith particular expertise in wireless communications, laser science, robotics, informatics, andmaterial science, to name just a few areas of research.
The UEC was selected for the Ministry of Education, Culture, Sports, Science and Technology (MEXT)
Program for Promoting the Enhancement of Research Universities as a result of its strengths inthree main areas: optics and photonics research, where we are number one for the numberof joint publications with foreign researchers; wireless communications, which reflects ourroots; and materials-based research, particularly on fuel cells.
