Abstract: A power semiconductor component for voltage limiting includes a rear-side base zone electrically contacted with a rear-side electrode and a front-side base zone electrically contacted with a front-side electrode. At least one switch-on structure is embedded at least into one of the rear-side base zone and the front-side base zone and is electrically contacted by the electrode contacting the embedding base zone. At least one triggering structure is provided as a breakdown structure of a first type, present between the front-side and rear-side electrodes. At least one further triggering structure is provided as a breakdown structure of a second type, present between the front-side and rear-side electrodes. The front-side and rear-side electrodes are each electrically conductively pressure-contacted by an electrically conductive contact plate at least one of which functions as a heat sink for dissipating heat generated in the semiconductor body.

Abstract: Independent refresh rates may be enabled for multiple monitors. Any displays that are presenting content in a full screen mode are refreshed at a rate set by the application presenting the content. All other devices are refreshed at a rate that is determined by a window manager based on various factors including the type of application(s) executing, the size of the applications presenting content, the location of the applications presenting content, hardware configurations, and so forth.

Abstract: A packaging machine and method for producing a packaging with a packaging machine, in which a lower material web is unrolled from a supply roll and transported along the packaging machine and at the same time a material to be packaged is placed on the lower material web and, to complete the packaging, an upper film is sealed to the lower material web in a sealing station, the packaging is cut from the upper and lower material webs, the cutting of the lower material web takes place partially upstream and partially downstream of the sealing station and/or partially upstream and partially in the sealing station.

Abstract: An upper sealing tool that includes a peripheral region and a recess, by way of which an upper film web is formed. The recess has a transition region and an inner region. The recess has a depth measured between the peripheral region and the inner region. The transition region has a first portion and a second portion. The first portion is provided in a convex state and the second portion is provided in a concave state. A ratio of the depth of the recess to a radius of curvature of the first portion is ?2.5. A ratio of the depth of the recess to a radius of curvature of the second portion is ?2.5.

Abstract: The invention relates to an upper sealing tool comprising an edge area (21) and a recess with which the upper film web is formed and the recess comprises a transitional area (22) and an inner area (23). The transitional area is located between the edge area and the inner area. The invention also relates to a packaging machine and to a method for producing a skin packaging.

Abstract: The present invention relates to a packaging machine comprising a sealing station which uses a sealing means to join an upper film web to a lower film web by sealing, said sealing means having at least one opening which is connected to a vacuum source and/or a source of substitute gas. The present invention also relates to a sealing frame.

Abstract: The present invention relates to a packing machine having:—a heating device, which heats up a film web—a forming station by means of which packing blisters are formed in the film web and/or the top film web, preferably by deep drawing;—a filling station in which the packing blisters are filled with a material to be packed;—a sealing station which seals a top film web to the packing blister; and—a longitudinal and/or transverse cutter, which separates the finished packages. The present invention also relates to a method for heating up a film web using a heating device which comprises a heated porous agent.

Abstract: The invention relates to a packaging machine, comprising a forming station, which has a deep-drawing punch, by means of which a film web is deep-drawn, wherein the deep-drawing punch is provided directly or indirectly on a drive, which moves the deep-drawing punch back and forth between two positions. The invention further relates to a method for installing a deep-drawing punch of a packaging machine on a drive or removing said deep-drawing punch from said drive.
