    Abstract: PROBLEM TO BE SOLVED: To provide diamond abrasive particles capable of clearly and uniformly forming texture streaks having a line density of ≥ 40 lines/μm on the surface of a magnetic hard disk substrate without forming an abnormal protrusion, and its manufacturing method. SOLUTION: The diamond abrasive particles are composed of artificial diamond generated by an impact method. The density of the artificial diamond is in the range of 3.0-3.35 g/cm 3 , preferably, in the range of 3.2-3.35 g/cm 3 . The average particle diameter of secondary particles of the artificial diamond is in the range of 30-500 nm. The average particle diameter of primary particles of the artificial diamond is in the range of ≤ 20 nm. Texture processing is executed by supplying polishing slurry, in which diamond abrasive particles are dispersed in water or a water base aqueous solution, to the surface of the rotating magnetic hard disk substrate 10, and by pressing a polishing tape 13 while sending out the polishing tape 13 on it via a contact roller 11.

    Abstract: PURPOSE:To simply generate a superhigh pressure as well as make the control of the pressure easier by a method in which an impact wave is applied against a substance to be treated in such a way as to apply a superhigh pressure to the substance by the interference of the impact wave. CONSTITUTION:A flyer acceleration part II, e.g., launch tube 13, etc., by which a flyer 9 present is forced to run is contacted with the diaphragm 8 of a high-pressure gas generatorI, and an impact wave generator III is provided on the outlet side of the flyer 9. The flyer 9 accelerated by the pressure of a light gas goes up in the launch tube 13, is discharged from the outlet of the impaction chamber 14, and collides against the protective cover 27 of a recovery capsule 15. Whereupon, an impact wave is produced inside a sample 25 and a superhigh pressure is generated by the interference of the impact wave. By the repeated use of such a simplified device capable of controlling pressure generated and of generating superhigh pressures, the synthesis of substances, etc., can be performed.

    Abstract: The process and apparatus according to the invention allow the production of hydrocarbons and ammonia without the use of catalysts. For this purpose, waste gases containing CO2 or N2 from an upstream process are fed to compression reactors. In addition, hydrogen from an electrolyzer is fed to these reactors to enable hydrogenation of the fed substances. Methane, alcohols and ammonia, for example, can be produced by this process. In order to increase the yield of the process, it is planned to raise the reactant pressure with the aid of a compressor.
