Abstract: A metal halide lamp includes a ceramic discharge vessel and two electrodes. The discharge vessel encloses a discharge volume containing an ionizable gas filling including at least a metal halide, two current lead-through conductors connected to the respective electrodes, and a seal of a sealing material through which at least one of the respective current lead-through conductors issues to the exterior of the discharge vessel. The sealing material of the seal includes a ceramic sealing material including cerium oxide, aluminum oxide and silicon dioxide as a mixture of oxides and/or one or more mixed oxides.

Abstract: The invention provides a metal halide lamp 1 with a ceramic discharge vessel 3 and two electrodes 4,5. The discharge vessel 3 encloses a discharge volume 11 containing an ionizable gas filling comprising at least a metal halide, two current lead-through conductors 20,21 connected to the respective electrodes 4,5, and a seal 10 by means of a sealing material through which at least one of the respective current lead-through conductors 20,21 issues to the exterior of the discharge vessel 3. The sealing material of the seal 10 comprises a ceramic sealing material comprising cerium oxide, aluminum oxide and silicon dioxide as a mixture of oxides and/or one or more mixed oxides. A good melting behavior of the sealing material was observed and lamps 1 with stable seals 10 and good light-technical properties were obtained.

Abstract: An electric discharge lamp comprising: —a translucent ceramic lamp vessel; —a first and a second current conductor, each supporting an electrode in the lamp vessel; —an ionizable filling comprising a rare gas and metal halide in the lamp vessel; at least the first current conductor being halide-resistant, characterized in that the first current conductor forms an end cap of the lamp vessel, wherein said end cap is made of a metal selected from the group consisting of molybdenum, tungsten, iridium, rhodium, and rhenium, or an alloy thereof, and wherein said end cap is sealed onto the lamp vessel provided with a cermet layer comprising 10-60 vol. % molybdenum and 90-40 vol. % Al2O3.

Abstract: The stamp (10) for use in a lithographic process, such as patterning a surface layer, of the invention has a stamp body (1) with a first (11) and a second side (12), at which first side (11) a printing face (2) is present and at which second side (12) a stack of a carrier body (4) and a reservoir (3) for liquid are present. The carrier body contains channels (5) in order that the liquid can be transported from the reservoir (3) to the stamp body (1) and further to the printing face (2). The stamp may be embodied as a cylinder, allowing a continuous lithographic printing process. This process results in patterns on a micron or submicron scale. The stamp (10) may furthermore be included in a larger apparatus.
