    • The invention provides a polishing pad conditioner that enables stabilization of brazing metal melting point, minimization of abrasive grain detachment by uniformizing and stabilizing abrasive grain brazing condition, and enhancement of flatness by minimizing thermal deformation of the metal support. The polishing pad conditioner is fabricated by brazing multiple abrasive grains to the surface of a metal support with brazing metal, wherein the composition of the brazing metal expressed in mass % is such that 70%≦Ni+Fe≦90% (provided that 0≦Fe/(Ni+Fe)≦0.4), 1%≦Cr≦25%, 2%≦Si+B≦15% (provided that 0≦B/(Si+B)≦0.8), and 0.1%≦P≦8%.
    • 本发明提供一种抛光垫调理剂,其能够稳定钎焊金属熔点,通过均匀化和稳定磨粒钎焊条件来最小化磨粒剥离,并通过最小化金属载体的热变形来提高平坦度。 抛光垫调节剂是通过钎焊金属将多个磨料颗粒钎焊到金属支撑体的表面上制造的,其中以质量%表示的钎焊金属的组成使得70%<= Ni + Fe <= 90%(条件是 0 <= Fe /(Ni + Fe)<= 0.4),1%<= Cr <= 25%,2%<= Si + B <= 15%(条件是0 <= B /(Si + B) = 0.8),0.1%<= P <= 8%。

    • A subirrigation system 10 includes a water-impervious member 16, and keeps water content in soil of a cultivated land 200 in a proper state for growing a plant. The water-impervious member 16 is formed into an upper opening vessel shape, and has a water reserving function. Water is fed to an inner portion of the water-impervious member 16 from a water tank 12 via a feed water pipe 14, whereby a soil portion 26 in a gravitational water state is formed. A water level 28 of the gravitational water within the water-impervious member 16 is properly controlled to a desired water level by a water level controller 18 provided in the feed water pipe 14. The gravitational water within the water-impervious member 16 controlled to the desired water level is appropriately sucked up to the soil in an upper layer in accordance with a capillary phenomenon. Accordingly, a soil portion 30 in a capillary water state having proper water content is formed in the cultivated land 200.
    • 子灌溉系统10包括不透水构件16,并且在适当的状态下将耕地200的土壤中的含水量保持在植物生长中。 防水构件16形成为上开口容器形状,并具有储水功能。 水通过给水管14从水箱12供给到不透水构件16的内部,由此形成重力水状态的土壤部分26。 不透水构件16内的重力水的水位28被设置在给水管14中的水位控制器18适当地控制到期望的水位。防水构件16内的重力控制到 根据毛细管现象,期望的水位被适当吸入上层的土壤。 因此,在耕地200中形成具有适当含水量的毛细水分状态的土壤部分30。
