Thank you very much, Mai kun. He submitted this article. He is now an internship student of the Department of Information and Computer Sciences of KAIT. He is a fourth year student of Chlalongkorn University, and he is supposed to proceed to the master's degree after he returns to Chula. Thanks to him, our research makes big progress and in addition, the atmosphere of our lab become brighter and more active.
On Friday, 7 July 2017, we had a little tour at Railway Technical Research Institute (RTRI) in Kokubunji and NTT (Nippon Telegraph and Telephone) Musashino R&D Center. It is a group of 20 people, 11 Chula students, 7 KAIT students, Prof. Hiroshi Tanaka and office manager of the international department.
In the morning we visited RTRI. It is an amazing fact that Japan railway research has continued over the century.
There, we visited a few of their test station. But because of photograph is prohibited, we don’t have any photo of their testing site. The first station we visited was a pantograph testing site. It is made to test the vibration of the pantograph at speed up to 500 km/hr and acceleration up to 2 m/s^2 (If I remember it right ><)
The guide (blue helmet) talked about RTIT faculty and where are we going to visit today. This is the last picture we can take before visit their testing site.
This is a pantograph. Its job is to keep the contract between the train and the electric wire above.
Next, we visited earthquake test site. The earthquake is simulated on a horizontal vibration table which is 1 meter by 1 meter. The amazing thing here is the vibration isolation system they have. The table is place on a HUGE MANY TON concrete with a lot of air spring and damper below.
Next, we visited train speed test station which can take up to 700 km/hr (I even don’t think this is correct lol). The 1 or 2 car trains will be put on a giant machine that speed up the wheel of the train while can be generate some extra vibration to simulate a rail track.
The last station we visited was a landslide test site. They simulate landslide by make a ton load of sand or soil into a like-triangle shape like slope on the mountain, then drop some rain by water sprinklers above and then observe some landslide. We have a chance to try the heavy rain simulation they make for us. They made a rain as hard as they could (300 mm/hr) and made us stand there with an umbrella under the heavy rain.What a great experience. But the rain in Thailand in rainy season is heavier though.
After that, the last place we visited was a prototype train area where the guide explain each prototype history.
After we left RTIT we went to NTT research center. The first thing we did there was having a lunch (XD).
After we finished lunch, we went to see their 4 technology presentation (these are 4 technology I choose to see. No one know about this except Tanaka sensei, my laboratory members and you, the reader. Shhhh, don’t tell Thai student). And of course, no photographing allow here :( .
The first project we saw was the next-generation passwordless authentication. Basically, it was just a 2-factor authentication of a short bad password and pre-register device given secret key, awesome.

Next project we saw was “Visual Search”,The Smart Navigation System for Visitors to Japan. For short, it is a real world object embedded information using optical camera image processing and application. The technology they create and use were Angle-free object search technology and cloud database assist technology. The idea is to have users move around in an unfamiliar place with ease as they can obtain the information they need in their own language by just pointing a smartphone at a Japanese signboard, map ,building or product.

The next one was “Hitoe”, a clothing-type bioelectrical sensor. At cost around 20,000 Yen, you can have your own smart cloth that monitor your heart rate and electromyogram for medical purpose using wireless and smartphone technology.

The last one was “Buru-Navi”, the device that can imitate the sensation of being pull. This device work like a vibration on a normal phone but the difference is that the generated force is actually have one selected direction. The models we was given to try and play with was fishing game with Buru-Navi 3 type 1 degree of freedom and Buru-Navi 3 type 2 degrees of freedom which can select direction with app.
After we finished this session, we went to NTT history center of technology. Here, we can take photographs (YAY!!), so we took a lot. This is the place that they show their past research and contribution with Japan technology.
There are a lot of old model phones here. The speaker and microphone were very heavy back then.
Tanaka sensei try to show us the network port for PC on the old telephone.
What a classic model they got here.
Mr. Yuki Oga seem to enjoy using this thing.
Miss. Yuna Okayasu seem to enjoy as well. These guys were having fun (me too, having fun writing this article. LOL)
This is fiber optic manufacture technology. They said that the fiber optic preform on the right can use to make around 2,000 km fiber optic.
Me and Yuki looking at the Japanese shape satellite.
After all day walk, everyone seem exhausted. (except Tanaka sensei, of course. He still look fresh and full of energy)
The trip could not end without some group photos. Even though we tried, when face a camera, we try our best to have great pictures.
Everyone show off their shoulder phone that was given by NTT as a souvenir.
After we done, we arrived at KAIT around 17:30. Thank you very much for a great trip. We, Thai students, enjoy a lot staying here in Japan. Thank you for your great care. And thank you for reading.
This is me. Maitai Dahlan. Thank you again for reading.
