    摘要： In etching of silicon nitride with a phosphorus type, if etching is carried for a long time, silicon oxide tends to precipitate, and it has been impossible to constantly carry out the etching for a long period of time.By an etching method for silicon nitride using a composition comprising a phosphorus compound, a boron compound, a silicon compound and/or their fluorides thereof, there will be no precipitation of silicon oxide even when the composition is used for a long time. It is particularly preferred to further add nitric acid and/or a nitrate, whereby stability of selectivity will be increased.

    摘要翻译： 在蚀刻具有磷的氮化硅的情况下，如果长时间地进行蚀刻，则氧化硅容易析出，长时间不能长时间地进行蚀刻。 通过使用包含磷化合物，硼化合物，硅化合物和/或其氟化物的组合物的氮化硅的蚀刻方法，即使长时间使用该组合物，也不会发生氧化硅的沉淀。 特别优选进一步加入硝酸和/或硝酸盐，从而提高选择性的稳定性。

    摘要： Disclosed is a lubricant sealing structure for a gear coupling, which can firmly prevent the leaking of the lubricant due to vibration or the like in the axial and radial directions inside the gear coupling. A sealing member is a cloth-inserted rubber 21 having flexibility. The cloth-inserted rubber 21 has a first end being fixed to a fixing member 24s on a cover plate 20 mounted on a side of an outer ring 7 and a second end being fixed to another fixing member 25s on a side of the drive shaft 10 in liquid tight manner in the axial direction of a drive shaft 10. Each of the first and second ends of the cloth-inserted rubber 21 has a face extending in a direction that is perpendicular to the axial direction. The cloth-inserted rubber 21 seals the lubricant at the face of said each of the first and second ends.
