Abstract: An electrolytic polishing treatment method for a nickel-based alloy workpiece made by lamination manufacturing comprises the following steps. Step (A) comprises performing a sandblasting treatment on the nickel-based alloy workpiece, followed by ultrasonic oscillation of the sandblasted nickel-based alloy workpiece in an oxalic acid solution. Step (B) comprises placing the nickel-based alloy workpiece in an electrolyte solution containing methanol, sulfuric acid, and perchloric acid and performing electrolytic polishing on the nickel-based alloy workpiece at a constant voltage after step (A). The processes of oxalic acid activation and electrolytic polishing are used to avoid the problems of residual stress and processing directionality caused by conventional mechanical processing and make the surface properties of the entire workpiece uniform.

Abstract: A terminal device and a terminal device installation method are provided. The terminal device includes a machine body, a detachable cover with two side walls, and at least two coupling mechanisms arranged symmetrically. The machine body includes a front board, a rear board opposite to the front board, and two side boards connected between the front board and the rear board. Each coupling mechanism includes a coupling portion located at one side wall, a front track and a rear track respectively having a front opening and a rear opening opposite to the front opening and both located at one side board. As each coupling portion is coupled to each front track, the cover is assembled with the machine body and covers the front board, and as each coupling portion is coupled with each rear track, the cover is assembled to the machine body and covers the rear board.

Abstract: A computer implemented method for managing the scope of permissions granted by users to application that includes collecting a set of permissions for an application from an application provider publication; and collecting a process flow for functional steps of the application from a review of the application that is published on a product review type publication. The computer implemented method further includes dividing the functional steps of the application into a plurality of journeys, each of said plurality of journeys having a function associated with a stage of a functional step from a perspective of a user; and matching permissions from the set of permissions for each journey of said plurality of journeys to provide matched permissible permissions to journeys stored in a customer journey store.

Abstract: A method for producing an adaptive element for dental implantation includes: creating a 3D virtual model including a crown part and a root part; obtaining a boundary curve between the crown part and the root part; defining a boundary plane on the root part perpendicular to a vertical axis of the 3D virtual model and spaced apart from the boundary curve; projecting the boundary curve on the boundary plane in a direction parallel to the vertical axis; generating a tubular model having a predetermined thickness based on the boundary curve, a virtual surface connected from the boundary curve to the cutting plane, and the cutting plane; and producing the adaptive element according to the tubular model.

Abstract: A magnetoresistive random access memory (MRAM) structure, including a substrate and multiple MRAM cells on the substrate, wherein the MRAM cells are arranged in a memory region adjacent to a logic region. An ultra low-k (ULK) layer covers the MRAM cells, wherein the surface portion of ultra low-k layer is doped with fluorine, and dents are formed on the surface of ultra low-k layer at the boundaries between the memory region and the logic region.

Abstract: An open-end wrench and a method of manufacturing the same are provided, the structure of which includes a body and a cover. The body includes a head portion and a handle portion, and the head portion includes a jaw portion and an opening formed at an inner side of the jaw portion. The cover includes a first plate, a second plate, and a third plate connecting the first plate and the second plate. An external surface of the third plate is formed to a wrench opening. A mouth is defined by external edges of the first plate, the second plate, and the third plate, and the mouth is penetrated by the jaw portion, so the cover wraps the jaw portion and the head portion is imbedded to the cover by using adhesive means.
