This is the most badly broken vertical pendulum. The bar where the cross spring at the fulcrum attached is broken. It is hard to imagine what kind of force would cause such a breakage. The appearance of the box has not changed much. The coil has also been removed from the mounting area. The wire is broken, so this is also very important. I am at a loss as to where to start.

The two horizontal components did not seem to change much at first glance, but the leaf springs at the fulcrums of both pendulums have all been torn off. In addition, the L-shaped 3D printed part of the magnet case holder in the lower right corner is broken from the root. I can only be disappointed, even though I used an expensive air mail service (shipping cost was 17,200 yen). Of course, I will file a claim for warranty after returning to Japan.

The coil came off the mounting .... Both wires are broken. This is going to be very difficult to repair.

A physics professor who helped me repair it. In the back right corner, a 3D printer was brought in to print from the STL file of the broken bar, but it took 6 hours to complete the job, and when I looked at it the next day, the print was broken in the middle.

At first, we did not have phosphor bronze sheets in stock to make springs, so Dr. O (whose nickname is "Dr. Ohm," a unit of resistance. D. in physics), who had invented the idea of cutting an aluminum juice can to make a spring. )

Replacement parts that were packed in a box. The broken parts for the horizontal comp. could be replaced with these, but not for the vertical comp.

A replacement part for the phosphor bronze plate found just before the scheduled repair time was up this morning. If I had found it earlier, I could have had a rest day today. The phosphor bronze plate is in the center, and the yellow ones on both sides are replacements made from aluminum cans. I replaced them in a hurry. Thanks to this, it took us until almost 3:00 p.m. after lunch, far exceeding the scheduled completion time of 11:30 p.m.

I put the two horizontal comps. waveforms on the floor for test observation. I had to downgrade the version of "Processing" to avoid the error, but I managed to get it to write waveforms. I am happy.

The center net-overed unit was stocked at LAZADA here, and is a power supply for an OP` amplifier. I could not find a cheap one even in Nihonbashi, Amazon or AliExpress, but to my surprise, I found it at LAZADA in Thailand, so I bought three units and brought two of them back to Japan for future use. The yellow horizontal motion (east-west motion) is covered with noise from the air conditioner wind. I have asked the professor here to cover it up.

A group of dogs, which Dr. L called "public dogs," roam around the campus of the Faculty of Science. She asked me if there were such dogs in Japan.

On the way back to my room by the science department, I saw people praying. Thai people are very religious. The building of the chemistry department on the left is getting a little tired.

This is the building where the physics laboratory is located. Today's seismograph repating was done in a room of this building.

It is a kind of a hall and accommodation for me, next to the Chemistry building. Go up the stairs from the door on the right.

There are two rooms up the stairs and a large lobby in front of them. Here you can boil water and prepare meals electronically. I boil water and drip coffee every day.

This is the room for accommodation, but I am the only occupant. It is spacious and comfortable, but the only drawback is that the hot water in the shower is always cold enough. I have asked them to fix it, but no one comes to fix.

When I went to the post office with Dr. L sensei this evening, I found this amazing one. It's fun to see such a big lizard or crocodile on the university campus. But when I approached it, it turned around as if it was trying to intimidate me.

I first went to the post office on the university campus (see the lizard's video), but they did not handle international mail, so I asked Dr. L sensei to take me to the post office in the city. At the PO, I waited for a while. When it was my turn, I deposited my luggage at the counter, and the clerk asked for my passport to confirm the sender. Actually, I left it in my room. We went out to get it, but Dr. L sensei had a brilliant idea to change the sender to herself instead of me. The next task, however, was to get a proof from the post office in order to get compensation from the Japanese post office for the badly damaged seismograph package later, so I went to another room in the back with the broken parts. To my surprise, there was a cute little cat, which seemed to be the postman's pet... Dr. L sensei negotiated with the postwoman and managed to write a proof of post office. I am still in a bit of trouble after I get back to Japan, but I always try to negotiate with the post office as if it is a learning experience. I went to the restaurant for dinner in the heavy rain that started to fall around the time I arrived at the post office. Dr. L sensei took me to the restaurant on the road, which was filled with water in some places due to the rain, while worrying that her new car, which was two weeks old, would be covered with water.

The professor who operates the various instruments for measuring solar radiation on the roof of the physics building explained them to us.

These tools are prepared in advance for the students of the SciUS course to conduct a flour fault experiment. Seismographs for demonstration is also available. All of them were brought in a suitcase.

Fault experiment. These are students of the SciUS course.

This is a microscopic observation of processed volcanic ash. The soil from Ibaraki, which was purchased locally, did not contain as many beautiful pyroxene as akadama soil. It would be better to bring Akadama soil from Japan next time.

This is a workshop for the students of a local public high school where the SciUS course students take regular classes (Thai language, social studies, etc.). The content was the same, but the target students were different.
