摘要:
A projection objective of a microlithographic projection exposure apparatus has a plurality of optical elements, for example lenses or mirrors. The objective furthermore includes an actuator for exerting a mechanical force that deforms a selected optical element of the projection objective. A manipulator modifies the spatial position of one of the optical elements as a function of the force exerted by the actuator.

Fiber-reinforced materials are produced by a process in which a heat-stable thermoplastic aromatic polyether A which contains reactive groups, preferably nitrile groups and/or sulfur bridges and/or arylthio or alkylthio groups, if necessary together with a heat-stable thermoplastic polymer B which does not contain any reactive groups, is applied onto reinforcing fibers, the resulting semi-finished product is molded and, in the molding obtained, the plastic matrix is crosslinked so that the glass transition temperature increases and it becomes virtually insoluble.

A working apparatus for processing, especially sealing, underwater bed areas, especially banks and bottoms of waterways, especially canals, a process for setting up said apparatus, a process for moving said apparatus and uses of said apparatus are described. The working apparatus comprises a plurality of polygonal hollow pipes arranged in parallel side by side and at least substantially without gaps, the upper ends of which form a horizontal, at least substantially flat working platform, wherein each hollow pipe has on its outer wall at least one projection extending substantially horizontally with a flange disposed on its outer end and extending vertically and at least one corresponding flange insertion aperture with a slot immediately above it which runs vertically and extends as far as the upper end of the hollow pipe, the flange insertion aperture being disposed further away from the upper end of the hollow pipe than the projection with the flange and being of greater horizontal dimensions than the slot, and wherein neighbouring hollow pipes are in engagement with one another via a respective projection on one of the hollow pipes with a corresponding slot in the other of the hollow pipes, such that the hollow pipes cannot be moved relative to one another in the horizontal direction and only at the outer edge of the working platform can at least one hollow pipe be pulled out individually in the vertically upward direction.

A telecommunication system includes a base station, a router allocated to the base station, and several subscriber stations that are connected to the base station via an access network. Subscriber station routers set up a telecommunication link with the base station router. The base station router controls the variable transfer rates that are allocated to a telecommunication link between the base station and the subscriber station. The access network is only loaded with the transfer bandwidth that is actually required for data transmission.

A backplane for establishing a signal connection between a plurality of cards comprises a support for signaling lines and a plurality of card slots located on the support in a predefined sequence for connecting a card. A plurality of signal-carrier contacts is located at each card slot according to a same pattern. At the card slots, at least two positions of contacts are defined such that a contact at one of these two positions, referred to as the 0-th position, of each card slot that has a successor in the sequence is connected to a contact at the other position of the successor card slot, referred to as the first position, via the backplane.

Thermoplastic molding materials containing a mixture ofA. a heat-stable polymer, e.g. a polyether sulfone or polysulfone, which does not contain any reactive groups, andB. a heat-stable polymer which contains reactive groups, preferably nitrile or thioaryl groups and/or sulfur bridges,can be processed to moldings, which can be crosslinked, for example by being heated at above 200.degree. C., so that the plastic matrix becomes virtually insoluble.
摘要:
An adjusting optical element mount (1) serves for the position of two components (2a, 2b) in relation to one another, in particular of two carrier elements for optical elements, such as mirrors or lenses, in particular as an axial and/or angle manipulator for lithography lenses. The components (2a, 2b) can be adjusted in relation to one another via the action of force (F, T). Each of the components (2a, 2b) has at least three hinges (4a, 4b, 4c, 4d, 5a, 5b, 5c, 5d). Each of the hinges (4a, 4b, 4c, 4d) of one component (2a) is connected in each case to a corresponding hinge (5a, 5b, 5c, 5d) of the respectively other component (2b) to form a pair of hinges (7a, 7b, 7c, 7d) via a lever element (6a, 6b, 6c, 6d) in each case. Each of the pairs of hinges (7a, 7b, 7c, 7d) is connected in each case to at least one lever (8a, 8b, 8c, 8d; 13, 13′) of at least one of the adjacent pairs of hinges (7a, 7b, 7c, 7d) via the at least one lever (8a, 8b, 8c, 8d; 13, 13′)and at least one further hinge (9, 9′; 9a, 9b; 9a′, 9b′) in each case.
