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.

A watertight and thermally insulating tank built into a bearing structure includes at least one wall having a variable width and forming oblique solid angles of intersection with the adjacent walls, the tank includes secondary insulating and watertightness barriers and a primary insulating barrier which are formed by panels fixed to the walls and able to hold a primary watertightness barrier. The primary water-tightness barrier includes, at each variable-width wall, one or more central strake(s) (63) arranged longitudinally and each fixed to underlying panels (12), running strakes (66) being held mechanically, by a sliding joint, parallel to the oblique solid angles of intersection, on underlying panels and fixed at the ends to the central strakes, so that the tensile forces (F) experienced by the running strakes in their longitudinal dimension are transmitted to the bearing structure via the central strakes. ving a first diaphragm surface, which faces away from the reference pressure chamber and can be exposed to the measured pressure, and a second diaphragm surface, which faces the reference pressure chamber; a reference pressure path which extends between a surface which can be exposed to the reference pressure and an opening in the reference pressure chamber, with the result that the second diaphragm surface can be exposed to the reference pressure; and a filter element which is arranged in the reference pressure path; wherein the filter element comprises hydrophobic or hydrophobicized, nanoporous material. 2. The relative pressure sensor as claimed in claim 1, in which the nanoporous material is arranged as a layer on a support material or in the matrix of a porous support material. 3. The relative pressure sensor as claimed in claim 1, in which the nanoporous material contains one of the substances Al2O3,TiO2,ZrO2,B2O3,CeO2,mullite, zeolite, silicates (aluminosilicates, aluminum beryllium silicates, apatite, cordierite), phosphates, SiC or Si3N4,carbon, Vycor Glass or mixtures of these substances. 4. The relative pressure sensor as claimed in claim 1, in which the nanoporous material comprises an ormocer or an inorganic polymer, in particular silicone resin, polycarbosilanes or polycarbo-silazanes. 5. The relative pressure sensor as claimed in claim 1, in which the nanoporous material has a mean pore diameter of less than 4 nm, preferably less than 2.5 nm, more preferably between 0.4 and 2 nm, even more preferably between 0.5 and 1.5 nm, and particularly preferably between 0.7 and 1 nm. 6. The relative pressure sensor as claimed in claim 1, in which the nanoporous material is laid with a hydrophobic layer. 7. The relative pressure sensor as claimed in claim 6, in which the hydrophobic layer contains at least one organosilane. 8. A device, comprising a housing (40) which defines a chamber (41) in its interior which comprises at least one aperture (42, 43) through which the chamber is in fluid communication with the environment of the housing (40) by means of a gas exchange path and at least one filter element (44, 45) disposed in the gas exchange path, said filter element comprising a hydrophobic and/or hydrophobicized, nanoporous material. 9. The device of claim 8, wherein the chamber (41) comprises an inlet aperture (42) and an outlet aperture (43), wherein filter elements (44, 45) are disposed in both gas exchange paths, respectively, said filterelements (44, 45) comprising a hydrophobic and/or hydrophobicized, nanoporous material. 10. The device according to claim 9, further comprising a ventilator to effect an air flow through the inlet aperture 44 and the outlet aperture 45. pins, and in which the locking pins are lifted by insertion of a key such that the end faces of the tumbler pins flush with the circumferential surface of the plug, in which at least one of the driver pins comprises two members, of which a first member is movable relative to the second one in the longitudinal direction of the pins, wherein the movable member in the rest position abuts on the second member with a contact portion directed towards the plug, and wherein at least one driver pin consisting of two members has a closer tolerance in the associated bore compared to the remaining driver pins. 2. A cylinder lock according to claim 1, wherein the second member of the driver pin is a bowl having approximately the same diameter as that of the tumbler pins and having an open blind hole facing away from the plug, in which blind hole the first member is arranged. 3. A cylinder lock according to claim 2, wherein the spring for a driver pin consisting of two members abuts on the movable member. 4. A cylinder lock according to claim 2, wherein the two members of the driver pins have approximately identical masses. 5. A cylinder lock according to claim 1, wherein the driver pins comprise a tube closed at both ends, in which tube an axially movable mass is enclosed. 6.
