[求助] 国外专利下载不到啊！！！求助！

最近需要查找的文献大部分是国外的专利，但是不知道怎么下载？求帮忙...
最好教一下方法！
文献名如下：
1. Ceramic rotor for radial turbo machines utilized in tunnel-type micro gas turbine engine, has complex configuration channels including conical sections, and rotor made as single block in which channels are made by laser prototyping
2. Gas turbine engine for e.g. aircraft propulsion, has turbine equipped with integrated case/stator segment that is comprised of ceramic matrix composite material
3. Segmented component e.g. segmented ceramic matrix composite turbine vane for gas turbine engine, has gas path portion whose middle portions are provided to form pressure side and suction side of stationary vane
4. Impeller i.e. ceramic impeller, for centrifugal slurry pump used in mineral processing application used to handle liquids and slurries, has projections that are spaced away corresponding apertures with respective axis of rotation
5. Erosion-resistant electrical submersible pump for hydrocarbon production from oil well, has impellers installed on shaft and spacers installed between impellers and diffusers, where impellers are manufactured from ceramic material
