The invention relates to a high-frequency grounding device () for use with a vacuum valve for closing and opening a valve opening of a vacuum chamber system, having a grounding band () made of a conductive material for discharging electrical charges occurring on the vacuum valve, wherein the grounding band has a first end () and a second end () and, for grounding the vacuum valve, is designed to be connected at the first end to a valve closure of the vacuum valve, and to be connected at the second end to a component of the vacuum chamber system, wherein the high-frequency grounding device has a correction impedance, wherein the grounding band is coupled to the correction impedance so that a resonant circuit results, which comprises the grounding band and the correction impedance, and the correction impedance has a first element for shifting a resonant frequency of the resonant circuit and/or a second element for reducing a quality of the resonant circuit. The invention additionally relates to a vacuum valve and a vacuum chamber system having such a high-frequency grounding device.

High-frequency grounding device and vacuum valve having high-frequency grounding device

A vacuum valve or door having a closure plate for closing an opening in a wall. The opening has opposing first and second longitudinal edges and shorter opposing first and second transverse edges. A sealing unit seals the closure plate against the wall in the closed position. The sealing unit includes a supporting frame having opposing first and second longitudinal legs and shorter opposing first and second transverse legs, on which supporting frame there is mounted on one side a circumferential closure plate seal and on the other side a circumferential wall seal. The supporting frame is secured to fastening points on the wall, with central portions of the first and second longitudinal legs being free with respect to the wall, or the supporting frame is secured to fastening points on the closure plate, with the central being free with respect to the closure plate.

Vacuum valve or vacuum door

The invention relates to a solar power installation which is characterized in that the supports of the solar modules are stacked one above the other when in the 'off' state and are extended by means of a transfer and lifting mechanism when in operating mode. The installation is also equipped with a controller which allows the installation to put the system into the safe off state in adverse conditions. The system is also advantageously suitable for stored energy sources and fueling electric vehicles.

Device for photovoltaic installation

The present invention relates to a device for the treatment of a workpiece, in particular of a substantially flat substrate, comprising a table () for supporting the workpiece (), a flow generation apparatus () producing a gas flow () on a top face () of the table () in a region between the workpiece () and the top face () of the table (), on which gas flow the workpiece () is supported during the treatment.
