摘要： A method for fabricating a lamination structure of a second-generation high-temperature superconducting (2G-HTS) tape is provided. Suitable lamination tapes are selected and subjected to local oxidation on side to form a locally oxidized region having a target pattern. The lamination tapes and a to-be-laminated 2G-HTS tape are sequentially arranged, where the locally-oxidized side of each of the lamination tapes faces toward the 2G-HTS tape. The lamination tapes and the to-be-laminated 2G-HTS tape are simultaneously immersed in a molten solder pool, and subjected to reel-to-reel squeezing lamination to form the desired lamination structure. A lamination structure fabricated by the method is also provided.

摘要： A method may include removing a portion of a base component adjacent to a damaged portion of the base component to define a repair portion of the base component. The base component may include a cobalt- or nickel-based superalloy, and the repair portion of the base component may include a through-hole extending from a first surface of the base component to a second surface of the base component. The method also may include forming a braze sintered preform to substantially reproduce a shape of the through-hole. The braze sintered preform may include a Ni- or Co-based alloy. The method additionally may include placing the braze sintered preform in the through-hole and heating at least the braze sintered preform to cause the braze sintered preform to join to the repair portion of the base component and change a microstructure of the braze sintered preform to a brazed and diffused microstructure.

摘要： A method for manufacturing an electrostatic chuck with multiple chucking electrodes made of ceramic pieces using metallic aluminum as the joining. The aluminum may be placed between two pieces and the assembly may be heated in the range of 770 C to 1200 C. The joining atmosphere may be non-oxygenated. After joining the exclusions in the electrode pattern may be machined by also machining through one of the plate layers. The machined exclusion slots may then be filled with epoxy or other material. An electrostatic chuck or other structure manufactured according to such methods.

摘要： An injection apparatus for injection material is disclosed. The injection apparatus includes a tank for storing material. The injection apparatus further includes a head body that has a surface for contacting a substrate and an opening part opened at the surface for discharging the material in fluid-communication with the tank. The injection apparatus further includes a member connected to the opening part, in which the member allows gas to flow into and flow out from the opening part.
