  • Publication number: 20220014057
    Abstract: A rotor structure of a magnet motor includes a rotating shaft and an iron core on the rotating shaft. Magnet grooves are disposed inside the iron core along a circumferential direction with a magnet provided therein. A distance between an edge line of the magnet groove close to a circumferential edge of the iron core and the circumferential edge of the iron core varies so that a width of a flux barrier formed varies. One end of a long side of the magnet groove close to the circumferential edge is formed with an anti-demagnetization groove communicating with the magnet groove, and an edge line of the anti-demagnetization groove tilts toward the circumferential edge of the iron core. Process slots are provided between the magnet grooves and the circumferential edge of the iron core that are used to increase a salient rate and reluctance torque of the motor.

  • Publication number: 20210358730
    Abstract: Techniques produce integrated native metal oxide discrete elements which can be used to fabricate discrete dynode electron multiplier (DDEM) devices, for example by creating dynodes with a native oxide as secondary electron emissive (SEE) layer from a metal block. The metal block may comprise or consist of a metal base component, for example Al, Al alloys or BeCu, of metal oxide SEE materials Al2O3 or BeO. Growing a native oxide from these base metals, Al2O3 or BeO eliminates the need of a costly and time-consuming SEE coating on the dynode surface. Furthermore, aluminum alloys offer intrinsic dopant, in particular magnesium where its oxide provides a higher secondary electron yield than the aluminum oxide. The use of aluminum, its alloys or BeCu material block allows flexibility in design and fabrication of DDEM without an SEE coating process.

  • Publication number: 20210342235
    Abstract: Techniques for managing a storage disk involve monitoring a duration of a fault of a faulted storage disk, wherein the faulted storage disk includes a first disk slice configured to store metadata and a second disk slice configured to store user data. The techniques further involve, in response to the duration reaching a first threshold value, replacing the first disk slice with a first available disk slice in a first non-faulted storage disk. The techniques further involve, in response to the duration reaching a second threshold value greater than the first threshold value, replacing the second disk slice with a second available disk slice in a second non-faulted storage disk. Accordingly, fault monitoring windows with different lengths are applied to disk slices for different logical tiers in the faulted storage disk. In this way, the reliability of data of a metadata tier can be effectively improved.
