The air sent by the hose passes through the pipe, enters the opening / closing valve in front of the mouth, chews with teeth, and when the valve opens, it passes through the pipe on the opposite side and jets out into the mask. Air sucks through the nose.
From "Friend of diving"
The Okushuki formula was created by Riki Watanabe, a graduate of a fishery lecture hall, the predecessor of Tokyo Fishery University, for collecting pearl oysters, pearl farming, etc., created by Ogushi Kanzo, and Watanabe's merit of Okushi I praised it and named it the Okushi style.The direction of evolution of a submarine is heading toward how much air consumption is reduced. In the free flow, drifting of the regulator, the air quickly disappears. This free flow state is a fixed dose type. A traditional submarine such as a helmet type submersible is this fixed dose air supply.Like today's scuba, the way the air flows only when sucking is a demand type, obviously the consumption of air is so small that the demand type is not comparable. As the valve to flow air only when requested, the simplest is manual. Only open the valve by hand when sucking. It is primitive to turn like a tap of a tap, but push it. It is also possible to push by hand. In fact, scuba of the type pushing with the fingers of the hand was conceived, it was made, and some of them were also put into practical use. The Okushuki formula is a tooth-motion type that performs opening and closing of a valve by chewing with teeth. I thought about that. Diver is a demand system in which air blows into the mask covering eyes and nose when biting an on-off valve lever like a washing scissors located in front of mouth under a single eye mask which diver covers nose and eyes .
The Okushuki formula is said to be the original ancestor of the scuba before Aqualang. The painting of the ship's science gallery's exhibition is also a scuba. Applications for patents have been issued to the UK in 1918 in the form of carrying tanks. However, it has not been used as a scuba.Because the tank capacity and filling pressure was low, it probably could not have been able to dive for such a practical time.
However, it is a mask type submersible that blew out of the world. 1924 (Taisho-kun) Taro Kataoka successfully raised the bullion from the Yasaka Maru from the water depth of 70 meters off the Mediterranean and Alexandria.
About these things, there is Moriyuki Yamada "Golden of the Ocean Bottom" Kodansha 1985 nonfiction novel. It is said that he wrote a dentist, but it is very interesting. However, I think that the color of fiction is dark in the part about taking white butterfly shellfish in the Arafura Sea.
Focusing on the deep dive performance of the Okushi style, it was also used for dive survey of fixed net and repair of net. Yoshitsugu Yamashita, a graduate of the fishery training institute, and Miura Tananoaki, who also conducted the diving survey of the stationary net themselves and guided themselves. In the survey of stationary nets, it is common for dive to exceed the depth of 50 m, and as far as the diving for fishery is concerned, everyone thought that Japan's diving technology is the world's best. However, in 1935, my birth year, "Friend of diving" Miura Tsunoyuki Assistant Nippon Diving Co., Ltd. According to 1935, two men who are Miura seniors lost their lives with diving and most of the divers I have a drowsy disease.
The Japanese diving company that issued this book is the manufacturer of the mask type diving machine, and the "friend of diving" was written for promotion of that mask, Yamamoto style mask. Only Okushi style masks are known, but Yamamoto style is used more. The Okushuki style is used sooner and moreover, there are few people who know the Yamamoto ceremony, saying the achievement of raising the gold mass. Now I am just doing the Yamamoto ceremony with this "friend of diving". The place to open and close valves with chewing with teeth is the same as Okushi formula. If so, you can say that it is an imitation of the Okushi formula, but the captain Yamamoto Toranosuke who invented the Yamamoto ceremony said that he had arrived with difficulty for a long time, written in Yamamoto's sales promotion book, "Diving Friends" It is. I think that the reason why Yamamoto ceremony replaced the Okushuki ceremony was that it was easy to use. Even though the principle is the same, the diver chooses the easier to use. Perhaps, it seems that the power of chewing with teeth was lighter in the Yamamoto style, and the teeth did not hurt. Unfortunately, there is no actual kind of Yamamoto style anywhere. I can not compare chews.
Miura Noriyuki, who has a Yamamoto style mask, seems to be ahead of the Okushi expression. The on-off valve is located on the side of the mask, chews with teeth, moves the lever and opens and closes the valve.
When I entered the Dong-A submarine, Yamamoto style and Okushi style mask were hanging from the ceiling of one corner of the warehouse that was my workplace. In those days, I thought that such things are relics of the past I did not see touch. At one time there was a person who bought the mask, the president sold out and disappeared from my eyes. Perhaps I think that this was the last Yamamoto ceremony to move, still workable.The Japanese diving company was in the vicinity of my office now, under the permanent bridge. Even if I visit you I have no idea of the trace. I do not know when and when this company disappeared. If I write the history of Japanese submersibles if I write it, I have to investigate, but there is no clue. I have no time. If anyone knows something, please contact me. If you have a Yamamoto style mask, please contact this also.suga@suga.name is the address.
