    摘要: A microscopic imaging method for creating a microscopic sample image (1A) of a sample (1) comprises the steps of arranging the sample (1) on a sampling crystal (10); irradiating the sample (1) with excitation laser pulses (2, 3) and generating sample response pulses (4) with a sample response field as a result of an interaction of the excitation laser pulses (2, 3) with the sample (1); irradiating the sampling crystal (10) with probe laser pulses (5) being temporally synchronized with the excitation laser pulses (2, 3) and spatially overlapped with the sample response pulses (4) in the sampling crystal (10), wherein the probe laser pulses (5) have a shorter wavelength than the excitation laser pulses (2, 3); detecting the sample response field by electric-field sampling with the sampling crystal (10), using the sample response pulses (4) and the probe laser pulses (5); and calculating the sample image (1A) based on the detected sample response field, wherein the excitation laser pulses (2, 3) have a wavelength in a range from mid-infrared to visible light and the sample response pulses (4) are created by a coherent interaction process induced in the sample (1) and with a fixed phase relationship relative to the excitation laser pulses (2, 3), the sampling crystal (10) is a non-centrosymmetric crystal, the irradiating step is repeated at multiple sample points (1A), wherein at each sample point (1A) the irradiating steps are successively repeated with multiple temporal probe delays of the probe laser pulses (5) relative to the excitation laser pulses (2, 3), at each probe delay, a sum or difference frequency pulse (6) of a sample response pulse (4) and a probe laser pulse (5) is generated, and at each probe delay, a spectral interference pulse (7) is created by a spectral interference of the sum or difference frequency pulse (6) and the current probe laser pulse, the detecting step includes sensing a polarization state of the spectral interference pulse (7) by an ellipsometer device (40) at each probe delay, wherein the local sample response field at the sample point (1A) is derived from the polarization states sensed at all probe delays, and the sample image (1A) is calculated based on the sample response field detected at the sample points (1A).

    摘要: In a method of transporting objects with transport vehicles, a starting point, a destination, a starting time and an arrival time are noted as object coordinates in a space-time. A transport path network of possible transport paths together with average speeds on the possible transport ways is defined. Suitable transport paths of the possible transport paths between the object coordinates of the objects are determined and noted in the space-time. In the space-time, one of the suitable transport paths per object is bundled into driving routes of the transport vehicles, transport capacities and the actual locations of the transport vehicles of the plurality of transport vehicles being considered. The driving routes together with the object coordinates of the associated objects are transmitted to those transport vehicles involved. Then, the objects are transported in that the transport vehicles involved are driven along the transmitted driving routes.

    摘要: A magnetic closure device has two complementary magnetic closure elements. Each of the two complementary magnetic closure elements includes an elongated magnet carrier having a single direction of main extension, and a plurality of permanent magnets supported by the magnet carrier in defined positions along the direction of main extension. Each of the permanent magnets is permanently magnetized either longitudinally or diametrically with regard to the direction of main extension. The permanent magnets following to each other in the direction of main extension are arranged in a closure alignment pattern having a magnetic non-repetition length extending over three or more of the permanent magnets. The magnet carrier is bendable in at least one direction orthogonal to the direction of main extension.

    摘要: Disclosed is an apparatus having a rotatable wheel with a planar external circumferential surface, which is flat in a direction parallel to the axis of rotation of the wheel, at least one nozzle having a nozzle opening for directing a molten metal onto the circumferential surface and a collection means for collecting solidified fibers of metal formed on the circumferential surface from the molten metal and separated from the circumferential surface by centrifugal force generated by rotation of the wheel. The nozzle has a rectangular cross-section having a width of the nozzle opening in the circumferential direction of rotation of the wheel and a length transverse to the circumferential surface of the wheel which is greater than the width. An apparatus is provided for controlling a gas pressure applied to the liquid metal and delivers it to the circumferential surface of the rotatable wheel.
