연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The gas generator of claim 1 wherein the second chamber includes a plurality of said containers. 3. The gas generator of claim 1 wherein the at least one container comprises a cylindrical tube. 4. The gas generator of claim 1 wherein the ignition material within the first chamber is in tablet form. 5. The gas generator of claim 1 wherein the gas generant material within the at least one container is in wafer form. 6. The gas generator of claim 5 wherein the gas generant material within the at least one container comprises a plurality of wafers. 7. A gas generator comprising: a housing having oppositely disposed first and second ends, adjacent the first end, the housing at least in part defining a first chamber containing a quantity of ignition material and, adjacent the second end, the housing at least in part defining a second chamber containing a quantity of gas generant material; andan initiator operatively associated with the first chamber and in reaction initiating communication with at least a portion of the quantity of ignition material, the initiator, upon actuation, to initiate reaction of at least a portion of the quantity of ignition material to form ignition products;wherein the second chamber includes at least one container wherein at least a portion of the quantity of gas generant material is contained, wherein the gas generant material within the at least one container is in wafer form, the container having a perforated side wall and oppositely disposed first and second end walls, with the first end wall perforated and disposed adjacent the first chamber to allow communication of at least a portion of the ignition products therethrough and into contact with gas generant material therein contained to ignite the gas generant material to produce a product gas and with the second end wall perforated to allow gas flow communication of the product gas therethrough for discharge from the gas generator,wherein the at least one container is a cylindrical tube and at least one of the first and second end walls comprises a perforated retainer disk secured to a respective end of the cylindrical tube. 8. The gas generator of claim 7 wherein the perforated retainer disk comprises a plurality of deformable joinder tabs, the joinder tabs upon deformation to secure the retainer disk to the respective end of the cylindrical tube. 9. A gas generator comprising: a housing having oppositely disposed first and second ends, adjacent the first end, the housing at least in part defining a first chamber containing a quantity of ignition material and, adjacent the second end, the housing at least in part defining a second chamber containing a quantity of gas generant material; andan initiator operatively associated with the first chamber and in reaction initiating communication with at least a portion of the quantity of ignition material, the initiator, upon actuation, to initiate reaction of at least a portion of the quantity of ignition material to form ignition products;wherein the second chamber includes at least one container wherein at least a portion of the quantity of gas generant material is contained, the container having a perforated side wall and oppositely disposed first and second end walls, with the first end wall perforated and disposed adjacent the first chamber to allow communication of at least a portion of the ignition products therethrough and into contact with gas generant material therein contained to ignite the gas generant material to produce a product gas and with the second end wall perforated to allow gas flow communication of the product gas therethrough for discharge from the gas generator,wherein the first end wall at least in part comprises an igniter end retainer plate and the second end wall at least in part comprises an output end retainer plate. 10.
