The median tectonic line is favored. Elutriation is a method of classifying powder samples based on the principle of particle size measurement. The counterflow acting in the opposite direction to the centrifugal force forms a gradient layer of excited states based on size and specific gravity in the chamber installed in the rotor of the centrifuge. By lowering the rotational speed, gradually increasing the flow velocity of the countercurrent flow, or changing the equilibrium position, particles with specific gravity or small particles flow out of the chamber and are collected as a fraction.

It seems that Tobe Town announced on June 9 that the 2022 “Gongensan Nagashi Somen”, which is scheduled to be held from July to September every year, will be canceled. Canceled to prevent the spread of new coronavirus infection. We apologize for any inconvenience this may cause to everyone who was looking forward to it, but we ask for your understanding. Gongensan is also known as a small rammer, and is also called the ‘western rammer’ due to its rough rock faces, steep slopes, and chains. It is said that this mountain was built for individuals to develop their own funds by themselves and to train themselves in the same way as Mt. Ishizuchi. It is a place that is suitable for the word training, such as using an iron ladder to climb the slope and using a chain to climb the cliff, making it a difficult mountain to climb. The view from the top of the mountain looks like a magnificent view of the surrounding mountains. I would like to visit it once in the near future. The big event of Tobe ware, which controls the familiar Japanese ceramic industry, is finally being held for the first time in three years.

Tea bowls) with a dark glaze that resembles oil spotting (iron glaze) are designated as national traditional crafts. Succeeded in firing white porcelain in the Edo period, and production began in earnest. After the Meiji era, it seems that production has increased as a production center for tableware for Southeast Asia. After the war, it seems that handicraft techniques were highly evaluated by Soetsu Yanagi（Mingei movement）, Bernard Leach, and Shoji Hamada (Mashiko ware: Living National Treasure) who promoted the folk art movement. After that, it changed from a production area that mass-produces under the guidance of ceramic art such as modern design to a production area of porcelain, which is a traditional craft that emphasizes handmade and hand-painted. It is now popular nationwide. Pottery called Tobe ware began to be made in the middle of the Edo period, but according to the materials of the Tobe ware cooperative, the history of the production area goes back to the Asuka period. 1775 Ozu feudal lord, Yasutoki Kato-Ko orders Tobe to make porcelain. Josuke Sugino succeeds in the firing of porcelains.

When charcoal production was flourishing, it was used as fuel. From around 1955, it is often used as a log of shiitake mushrooms, which is a product of the former Hirota village.

I myself think of my childhood. “Masaki Town” : It is adjacent to Matsuyama City, the capital of the prefecture, with the Shigeobu River, which is a first-class river originating from the Ishizuchisan system, as a boundary. It is located in the southwestern part of the Dogo Plain.

The Seto Inland Sea, which extends to the north of Ehime Prefecture, is surrounded by the Shikoku Mountains and Chugoku Mountains in the north and south, and Honshu and Kyushu in the east and west. For this reason, the coastal area of the Seto Inland Sea always hits the leeward side of the mountains against the monsoons of summer and winter, so the annual rainfall is as low as 1,100 to 1,500 mm, and the annual average temperature is around 16 degrees Celsius, which is a relatively warm semi-ocean. It has a semi-inland Setouchi climate. On the other hand, unlike the Seto Inland Sea side, the Uwa Sea coastal area and mountainous areas in the southwestern part of the prefecture have relatively high annual rainfall of 1,600 to 2,000 mm, and there is also snow in winter, and this rain and snow have little rainfall. It seems to be a valuable water resource for the coastal area of the Seto Inland Sea. “Natsumi satsuma oranges” : ‘Kara（A variety announced in the United States in 1935, it is a fruit made by crossing “Owari Satsuma mandarin” and “King mandarin oranges”, and it came to Japan around 1955）Mandarin oranges’ whose parents were born in California, USA × Mating breeding of the native species ‘Yoshiura Ponkan Orange’ Oshima District, Yamaguchi Prefecture : Yashiro island ; Born at KOZO Yamamoto’s farm in Suo-Oshima Town.
