Abstract: A component for a projection exposure apparatus for semiconductor lithography, comprises an optical element and an actuator, which are force-fittingly connected to each other. The actuator at least locally deforms the optical element. The actuator can be configured to minimize the loss in rigidity at the peripheries delimiting the actuator on the imaging quality. A method for designing a component of projection exposure apparatus is provided.

Abstract: A device for detecting the position of a first or second vehicle to be coupled together, having a sensor device which can be arranged on the first or second vehicle and which detects at least one reference point of the other second or first vehicle using sensors. A device for detecting the position of a first or second vehicle to be coupled together, said device allowing an operationally reliable and precise coupling regardless of present environmental influences. The sensor device has at least one transceiver unit, and the at least one reference point can be equipped with a transponder which reflects a radio signal of the transceiver unit.

Abstract: A machine tool has a rotatable tool holder formed with an outwardly open seat having an outwardly directed floor and a cartridge engaged in the seat, carrying a cutting insert, and formed with an inwardly open groove defining a groove axis and having a surface confronting and extending at a small acute angle to the seat floor. An adjustment wedge axially shiftable in the groove has a formation extending transversely of the axis and bears radially outward on the groove surface and radially inward on the seat floor so that axial shifting of the adjustment wedge radially shifts the cartridge in the groove. An eccentric pin set in the cartridge engages the formation of the adjustment wedge for axially shifting the adjustment wedge in the groove and thereby radially displacing the cartridge in the seat on rotation of the pin.

Abstract: The invention relates to a cutting tool for metal removal. Said tool comprises a tool base holder (10), which can rotate around an axis and which comprises at least one recess for a cassette which is used as a tool support for a cutting insert (14), also comprising an adjustment device which comprises an eccentric pin (21) for radial displacement of the cassette. According to the invention, an adjusting wedge (18) is associated with the cassette recess and can be displaced in an axial direction by means of the eccentric pin.

Abstract: The invention relates to a method for coating a surface. According to said method, a coating substance having a viscosity of <100 Pa.s, measured at 25° C., is applied to a surface to be coated and left to harden. The inventive method is characterised in that, during the application of the coating substance, a gas flow is guided over the surface to be coated by means of at least one mobile overpressure ventilation device.

Abstract: For locating steel reinforcing members in construction materials, a galvanic cell is formed between an electrode and the reinforcing members by placing the electrode in electrically conducting contact with the construction material. When drilling an opening into the construction material using a hand-held drilling device and the drilling bit in the device contacts a reinforcing member, the potential difference between the electrode and the drill bit can be utilized as a signal for controlling the operation of the drilling device.
