Abstract: The invention relates to an apparatus for determining a layer thickness on a tape moved along a feed direction, comprising: a movement unit for moving the tape along the feed direction, a light generating unit for generating illumination radiation, a beam shaping unit disposed downstream of the light generating unit for shaping at least one strip-shaped illumination beam for linear illumination of the tape transversely with respect to the feed direction, a detector unit for detecting illumination radiation reflected and/or transmitted at the tape, and an evaluation device for determining the layer thickness on the basis of the detected illumination radiation. The apparatus can also be used for determining a degree of contamination of a surface of the tape, the surface being contaminated by particles, by detecting illumination radiation scattered at the tape.

Abstract: A loading flap is pivotally mounted on the backrest of a vehicle seat and can be locked with the backrest. The locking operation can be carried out using positive and/or non-positive means, e.g. a bolt that moves in a translatory and rotative manner during locking and unlocking. The loading flap includes a housing that may be moved in a translatory manner parallel thereto during opening.

Abstract: A personal scale has a housing having a generally horizontal upper platform wall adapted to be stood on by a person, and formed with a central boss shaped having sloped side surfaced angled to fit the longitudinal arch or instep of a person standing on the platform. An evaluating/display unit in the housing determines and displays the weight of the person standing on the platform.

Abstract: An illumination system for a microlithographic projection exposure apparatus has a first polarization manipulator, a second polarization manipulator and at least one optical element located between these manipulators. The polarization manipulators ensure that the direction of the electric field vector of a light ray varies in time between the polarization manipulators, whereas the polarization state is fixed outside the polarization manipulators. This prevents high energy light from inducing birefringence in optical elements arranged between the two polarization manipulators.

Abstract: A method for producing a quartz glass material with high resistance to radiation-induced density modifications when exposed to ultraviolet radiation at about 193 nm and energy densities of the order of the working energy densities of optical systems for microlithography, in which the peroxy defect level in the quartz glass material is minimized. In this way the creation of closely neighbored hydroxyl groups can be inhibited, which have been identified as an essential cause for radiation induced density reduction of the quartz glass material.
