  • Publication number: 20250063775
    Abstract: A semiconductor device includes a transistor having a plurality of gate trenches formed in a semiconductor substrate, the gate trenches patterning the semiconductor substrate into ridges. The transistor further includes a gate electrode arranged in at least one of the gate trenches. A source region, a channel region and a part of a current spread region are arranged in the ridges. The semiconductor device further includes a superjunction structure arranged at a larger distance to the source region than the channel region. The superjunction structure includes a first compensation region of the first conductivity type and a second compensation region of the second conductivity type. A doping concentration of the doped portion of the second conductivity type of the channel region decreases in a second horizontal direction intersecting the first horizontal direction from a region close to the gate electrode to a central portion of the ridge.

  • Patent number: 11083322
    Abstract: Methods and devices for determining the cooked state of eggs. These are characterised in particular in that the cooked state of the egg can be monitored and/or the cooking process can be ended when a desired cooked state has been reached. To this end, an egg is positioned in a vessel, the temperature is increased, and at least one light source is positioned on or in the direct vicinity of the egg. The transmission of light through the egg is determined and a transmission of at least 96% of the maximum transmission degree of a raw egg is achieved for a runny yolk, of at least 94% is achieved for a soft yolk, of at least 90% is achieved for a medium soft yolk, and at least 85% is achieved for a hard yolk.

  • Patent number: 9987587
    Abstract: A method for the treatment of a gas stream, wherein before the combustion of the gas stream, hydrogen sulfide is separated out of the gas stream in a first absorber by an absorption medium, the treated gas stream purified of hydrogen sulfide is burnt in a combustion apparatus, the carbon dioxide contained in the exhaust gas of the burnt gas stream after combustion is separated in a second absorber by an absorption medium, and the separated hydrogen sulfide and carbon dioxide are separated in at least one desorber from the absorption medium for the regeneration of the latter. The same absorption medium separates the hydrogen sulfide out of the gas stream and the carbon dioxide out of the exhaust gas. A corresponding device for the treatment of a gas stream has a first absorber and a second absorber flow-connected to one another for the exchange of absorption medium.
