という人の作４）１１こしたがっていた。Therefore, the life jacket is equipped with a corresponding carbon dioxide gas cylinder and a filling device that breaks the airtightness of the gas cylinder and sends the gas to the jacket.
It is installed, and when necessary - When the operating cable of the charging device is pulled by hand, the lever connected to the operating cable causes the firing pin in the charging device to break the seal of the gas cylinder, spouting out gas. I wanted to create 4) 11, a method created by someone who had to pull a lever to inflate the body in a short period of time.

在十分な対策は行なわれていない。For example, the firing pin that breaks the seal of a gas cylinder is made with a stopper made of Japanese paper or other material that softens when absorbed by water, and the firing pin is constantly pressed down with a spring. Gas cylinders often burst due to the force of the springs inside, causing life jackets to inflate, and there are currently no adequate countermeasures in place.

(Cu-2n-AI) alloys are used because they are inexpensive, but nickel-titanium (Ni-TI) alloys are also highly reliable in terms of corrosion resistance and durability.
``Furukawa shape memory NT gold alloy is good and has a transformation temperature of 1.
0°C to 90°C (-10°C to 110°C with special treatment)
) Also, the shape recovery stress is as large as 60 and 20.
There is almost no loss of memory unless left at 0° C. or higher for a long period of time, and the elongation rate is 20 to 6096, which has a wide design range, so it meets the purpose of the present invention.

ないものであったが本発明により従来の“欠点“が改善
できた。As shown in the embodiment of the present invention, for example, if a person wearing a life jacket is ejected from the ocean during a disaster and loses consciousness, the gas injection device of the present invention can react with water. However, the firing pin can break the seal of the carbon dioxide gas cylinder and inflate the life jacket due to the combination of the heat generating mechanism A and the firing pin, which allows an unconscious person to float in the ocean. However, the present invention has improved the conventional "deficiencies".

May 23rd 1, Incident Display 1986 Patent Application Drawing #007
No. 427 No. 2, Title of the invention Gas blowing device 6 Completion 1 flll No. 7 Negi Building 2F4, Subject of amendment O The claims of the specification are amended as follows (1)
A device characterized by ejecting gas from a gas cylinder filled with carbon dioxide gas, nitrogen gas, oxygen gas, etc. using the recovery stress of a shape memory alloy due to temperature changes. (2) The scope of the claim set forth in claim 1, characterized in that the expansion/contraction recovery stress of the shape memory alloy formed into a coil due to a temperature change is utilized. (3) The scope of the present invention is characterized in that it is an apparatus that simultaneously has the function of manually breaking the sealing plate of a gas cylinder and spouting out gas, and the function described in item 2 or item 1. (4) The claim described in item 3 or 2, characterized in that the substance coexists with a substance that rapidly changes temperature by interacting with water. "Although shape memory alloys made of metals such as nickel and titanium alloys were used in the present invention, transpolyisoprene, such as Kuraray TP-301, which is a shape memory synthetic resin that crosslinks when heated, is also completely suitable for the purpose of the present invention.
