摘要:
A sensor apparatus having at least one magnet core, on at least one carrier surface, which encompasses at least one soft magnetic material and for which a respective longitudinal center plane, which is oriented perpendicularly to the carrier surface and divides the respective magnet core into two halves having an identical mass, is definable, at least one coil being on, around, and/or adjacent to the at least one magnet core, the at least one magnet core having in its interior sub-regions by which an initiation of a magnetization reversal of the respective magnet core is targetedly locally controllable since a drive energy to be applied for propagation of a magnetic domain wall is elevated. Also described is a manufacturing method for a sensor apparatus having at least one magnet core, and a method for ascertaining a field strength of a magnetic field in at least one spatial direction.
摘要:
In a method for welding a first component having a channel to a second component, a lower surface of the first component is placed onto an upper surface of the second component, and a laser beam is transmitted through the first component and guided along a trajectory across the upper surface of the second component. The second component absorbs the laser beam along the irradiated trajectory, so that the irradiated trajectory of the second component is welded to the lower surface of the component in the form of a welding path. The channel has a rounded surface in a plane in which the laser beam is guided. The rounded surface is configured in such a way that a predefined power density of the laser beam is present at the upper surface, so that a continuous welding path is provided along the irradiated trajectory between the two components.
