摘要： An electric generator having a rotor with permanent magnets, configured for rotating about a rotation axis; a stator having at least one magnetic yoke with arms extending axially inside or outside of the rotor so as to be adjacent to a radial inner or outer side, respectively, of the rotor; wherein the arms of the at least one magnetic yoke are circumferentially distributed so as to form a slot between each pair of adjacent arms, each slot and each arm showing a width. The widths of the arms and/or the widths of the slots have different values distributed along the circumference. The invention is also directed to a valve having the electric generator equipped with a turbine wheel for being driven by a flow of gas in the valve.

摘要： A material deposition method comprising: preparing a precursor solution of Pb(Zrx,Ti1-x)O3 using 1-methoxy-2-propanol as a solvent and acetylacetone as a modifier; and forming a seed layer for a electroactive film by spin coating the precursor solution on a substrate. The electroactive film can be PZT, PZO or BFO, spin-coated or inkjet printed on the seed layer. Experience shows pure orientation for the piezoelectric film thanks to the use of 1-methoxy-2-propanol when preparing the seed layer. This orientation is attributed to the formation of nano crystals on the seed layer constituting a pre-crystallization.

摘要： A method for in-situ joint nanoscale three-dimensional imaging and chemical analysis of a sample. A single charged particle beam device is used for generating a sequence of two-dimensional nanoscale images of the sample, and for sputtering secondary ions from the sample, which are analysed using a secondary ion mass spectrometry device. The two-dimensional images are combined into a three-dimensional volume representation of the sample, the data of which is combined with the results of the chemical analysis.

摘要： A computer-implemented data processing method, including the steps of: providing a first program including a group of operations arranged to satisfy a first set of operation dependencies, the group of operations being adapted for computing data from at least one data source, generating a second program including the group of operations, arranged to satisfy a second set of operation dependencies, and processing the data from the at least one data source with the second program. The group of operations includes a first operation, a second operation, and a third operation. The first set of operation dependencies includes a first dependency between the first operation and the second operation, a second dependency between the first operation and the third operation, and a third dependency between the second operation and the third operation.

摘要： A secondary ion mass spectrometer comprising a primary ion beam device, and means for collecting, mass filtering and subsequently detecting secondary ions released from a sample due to the sample having been impacted by a plurality of primary ion beams. The secondary ion mass spectrometer is remarkable in that it uses a plurality of primary ion beams in parallel for scanning the surface of the sample.
