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 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 multi-pane glazing unit of claim 1 wherein the spacer consists of metal. 9. The multi-pane glazing unit of claim 1 wherein the spacer comprises a first metal strip defining a channel member, and the spacer comprises a second metal strip defining said engineered wall, such that said second metal strip defines both said first and second corrugation fields. 10. The multi-pane glazing unit of claim 9 wherein the channel member comprises two opposed, flat side walls that respectively define the two side regions of the spacer. 11. The multi-pane glazing unit of claim 9 wherein the first metal strip is more than 50% thicker than the second metal strip. 12. The multi-pane glazing unit of claim 11 wherein the first metal strip is at least twice as thick as the second metal strip. 13. The multi-pane glazing unit of claim 1 wherein the multi-pane glazing unit is an insulating glass unit, and said first and second panes are glass. 14. The multi-pane glazing unit of claim 1 wherein the glazing unit is a triple glazing having three panes and two between-pane spaces. 15. The multi-pane glazing unit of claim 1 wherein the first corrugation field and the second corrugation field each comprise corrugations that are generally trapezoidal, triangular, arcuate, square, rectangular, or generally follow a sine wave. 16. The multi-pane glazing unit of claim 1 wherein the corrugations of the first and second corrugation fields have peaks and valleys that are elongated in a lateral direction to as to extend straight across the width of the spacer. 17. The multi-pane glazing unit of claim 1 wherein the first corrugation field has peaks that are continuous with peaks of corresponding corrugations in the second corrugation field even though said peaks of the first corrugation field are of greater height than said peaks of the second corrugation field. 18. The multi-pane glazing unit of claim 1 wherein the second corrugation field is corrugated on a continuous uninterrupted basis along the length of the spacer, whereas the first corrugation field has a series of non-corrugated wall regions spaced apart along the length of the spacer. 19.

The spacer of claim 31 wherein said second and third corrugation fields have corrugations of the same configuration, while said first corrugation field has corrugations that are configured differently than the corrugations of said second and third corrugation fields. 33. The spacer of claim 22 wherein the spacer comprises a first metal strip defining a channel member, and a second metal strip defining the engineered inner wall, such that said second metal strip defines both said first and second corrugation fields, and the channel member defines the two side walls of the spacer, the two side walls of the spacer being opposed, flat side walls. 34.
