Abstract: In a production of a non-oriented electrical steel sheet by hot-rolling a steel slab containing Si: 2.8 to 6.5 mass% and Zn: 0.0005 to 0.0050 mass% followed by cold rolling and finish annealing, a coating agent containing at least one element selected from Sn, Sb, P, S, Se, As, Te, B, Pb, and Bi is applied to the steel sheet surface after the finish annealing to form an insulation coating with a nitriding-suppressing ability. Alternatively, an intermediate layer containing at least one element selected from Sn, Sb, P, S, Se, As, Te, B, Pb, and Bi and having a nitriding-suppressing ability is formed on the steel sheet iron matrix after the finish annealing and form an insulation coating not containing above elements is formed on the intermediate layer thus to obtain a non-oriented electrical steel sheet from which a rotor core with high strength and stator core with excellent magnetic properties after the stress-relief annealing can be obtained at the same time, and a motor core comprising a stator core and rotor coreis produced from the steel sheet.

Title: Image processing method and system
Inventor: Shi Bodi
IPC: G06T7/12
Filed: 2020-12-29
Abstract: A method of image processing includes: obtaining an original image and obtaining a to-be-processed image based on the original image (S200); recognizing the to-be-processed image by using an image recognition model to obtain a silhouette array (S202); generating a silhouette image based on the silhouette array (S204); and generating a target image based on the original image and the silhouette image, where the target image corresponds to a region of interest of the original image (S206). The region of interest is recognized and split from the original image based on the silhouette array and the silhouette image, and the region of interest (for example, a human body contour region) is recognized and split from the original image without using depth-of-field information. Therefore, hardware or a system with a high level of configuration is not required.

Abstract: A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. Housing side walls are joined to a cross member that has a flexion region on each side of the housing, each side wall having an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward, thereby urging the material, once hardened, against the teeth. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage.
