摘要:
A projection exposure system (10) for microlithography which includes: a mask holding device (14) holding a mask (18) with mask structures (20) disposed on the mask, a substrate holding device (36) holding a substrate (30), projection optics (26) imaging the mask structures (20) onto the substrate (30) during an exposure process, and a measurement structure (48) disposed in a defined position with respect to a reference element (16) of the projection exposure system (10), which defined position is mechanically uncoupled from the position of the mask holding device (14). The projection exposure system (10) also includes a detector (52) arranged to record an image of the measurement structure (48) imaged by the projection optics (26). The projection exposure system (10) is configured such that during operation of the projection exposure system (10) the imaging of the mask structures (20) and the imaging of the measurement structure (48) take place at the same time by the projection optics (26. An evaluation device (54) is configured to establish a lateral position of the image of the measurement structure (48) in the area of the detector (52) during the exposure process.

A lock device having a key and a lock cylinder. The lock cylinder includes a fixed cylinder housing and a cylinder core mounted to rotate therein. The key shaft (10.3) has an edge profile and may be inserted in a key way of the cylinder core in which displaceable tumblers (41, 42) are located transverse to the above. The key shaft (10.3) has profiled recesses running in the longitudinal direction. The recesses have a pair of follow points for each tumbler (41, 42) for coding the key, whilst the tumbler (41. 42) has a pair of counter follow points which are the basis of the corresponding counter coding. A space-saving design of the lock device is achieved with a large range of variation for the coding wherein both follow points are on the key shaft (10.3) in the form of recesses, arranged on opposing lateral surfaces to an edge (57.2; 57.3) of the edge profile of the key shaft (10.3). A web (22: 23) is thus generated in the corner region of the edge profile between both recesses. The web functions as a code web (22; 23), as the opposing web edges serve for the coding. The corresponding tumblers (41, 42) have a cut-out, which in use enclose the code web (22; 23) on opposing web edges. The lateral limits of the cut-out form the counter follow points in the tumblers (41, 42).

摘要:
The present invention relates to a process for the separation of at least one unbranched C4-C2O hydrocarbon from a fluid mixture containing the unbranched hydrocarbon and at least one branched isomer of the unbranched hydrocarbon, which comprises the step of—contacting the fluid mixture with an adsorbent comprising a porous metal organic framework material, which material comprises at least one at least bidentate organic compound coordinately bound to at least one metal ion, to get the unbranched hydrocarbon adsorbed, wherein the at least one at least bidentate organic compound is a monocyclic, bicyclic or polycyclic ring system which is derived from at least one heterocycle selected from the group consisting of pyrrole, alpha-pyridone and gamma-pyridone and has at least two ring nitrogens and is unsubstituted or bears one or more substituents selected independently from the group consisting of halogen, Ci-6-alkyl, phenyl, NH2, NH(d-6-alkyl), N(C1-6-alkyl)2, OH, Ophenyl and OCi-6-alkyl, where the substituents Ci_6-alkyl and phenyl are unsubstituted or bear one or more substituents selected independently from the group consisting of halogen, NH2, NH(d-6-alkyl), N(C1-6-alkyl)2, OH, Ophenyl and OCi-6-alkyl. The present invention also relates to the use of said porous metal-organic framework material in a process for the separation of unbranched hydrocarbons from their branched isomers.

The invention relates to an external handle on doors or hatches of vehicles, using a two piece (10, 20) housing, wherein a cavity (21) is generated between said pieces. A sensor (31, 32) is arranged in said cavity in a container (30). On operation, the sensor carries out certain functions in the lock. According to the invention, failures caused by the ingress of fluids into the cavity (21) can be avoided, wherein the container (30) is formed from an elastic molded mass (35), in which the sensor (31, 32) and optionally some further electric and/or electronic components for the sensor operation are embedded. An elastic surface (36) is achieved on at least one end piece of the container (30) by means of the molded mass (35). When assembled, the container (30) is pressed (41) with said elastic surface (36) against an inner surface (29) of the housing piece (10, 20). On pressing (41), the end piece of the container (30) deforms and functions as sealing means (40′), preventing an ingress of fluid between the container surface (36) and the housing inner surface (29).
