摘要： A porous absorbent made of a filter, a filter material or a sponge material is inserted into a polluted part of soil or groundwater containing environmental pollutants such as chlorinated solvents or heavy metal ions. The porous absorbent is inserted into the polluted environment such that its one end comes into contact with the pollutants and the other end is exposed to air. The porous absorbent allows the pollutants absorbed thereby to rise up to its air-exposed end through the vaporizing activity of the pollutant themselves and of the water containing them. The pollutants are allowed to evaporate from the air-exposed end to be dissipated into the air, or to concentrate at the air-exposed end for later removal. Further, microorganisms fixed to the porous absorbent are used to decompose pollutants for removal, or to absorb pollutants for removal. Those pollutant eliminating methods allow efficient elimination of even highly concentrated pollutants at a low cost without requiring complicated processes. The method based on the use of microorganisms is further advantageous in that it is less stressful to the environment and biologically safer.
摘要翻译：将由过滤器，过滤材料或海绵材料制成的多孔吸收剂插入含有环境污染物例如氯化溶剂或重金属离子的土壤或地下水的污染部分中。将多孔吸收剂插入污染环境中，使其一端与污染物接触，另一端暴露于空气中。多孔吸收剂允许吸收的污染物通过污染物本身和含有它们的水的蒸发活性而升高到其暴露于空气的端部。允许污染物从暴露于空气的端部蒸发，以排放到空气中，或者集中在暴露于空气的端部以供以后去除。此外，固定在多孔吸收剂上的微生物用于分解污染物以除去或吸收污染物以除去。这些污染物排除方法可以在低成本的条件下有效地消除甚至高浓度的污染物，而不需要复杂的过程。基于使用微生物的方法的优点在于其对环境的压力较小并且在生物学上更安全。

摘要： A powder for a magnetic recording medium comprising a plurality of magnetic particles and a coating covering the surfaces of the magnetic particles. The coating is a residue resulting from the thermal decomposition of an organic material. The powder is manufactured by applying one or more organic materials to the surfaces of a plurality of magnetic particles by dispersing the magnetic particles in a solution containing the organic material. The magnetic particles, having the organic material as a coating, are separated from the solution, and the magnetic particles are heated to a temperature at which the organic material decomposes.
摘要翻译：一种用于磁记录介质的粉末，包括多个磁性颗粒和覆盖磁性颗粒表面的涂层。涂层是由有机材料的热分解产生的残留物。通过将磁性颗粒分散在含有有机材料的溶液中，将一种或多种有机材料施加到多个磁性颗粒的表面来制造粉末。将具有有机材料作为涂层的磁性颗粒与溶液分离，并将磁性颗粒加热至有机材料分解的温度。

摘要： Barium-ferrite series powders are prepared from an alkaline aqueous solution containing a prescribed ratio of ions of the metals equal to those contained in the powder. In the first stage, the alkaline aqueous solution is heated at a constant volume at 150.degree. to 300.degree. C. to precipitate a precursor of the barium-ferrite series powder. Then, the precursor is baked at 700.degree. to 1,000.degree. C. to crystallize the precursor.
