摘要： This invention allows the surface of an austenitic stainless steel screw surface to be formed into a hard nitrided layer so as to harden and a part such as a screw head which is in contact with outside air is removed its own ultra hard surface layer in the hard nitrided layer by scouring or the like to be rust preventive. Even if the ultra hard surface layer is thus removed, an inner hard layer in the hard nitrided layer is present beneath the surface layer to be able to maintain a hard state of the screw surface. In the method for manufacturing the austenitic stainless steel screw according to the invention, upon forming said hard nitrided layer on the screw surface by nitriding, the austenitic stainless steel screw surface is cleaned with a fluorine- or fluoride-containing gas prior to nitriding. Thereby remained foreign matter, oxidized layer and the like on the screw surface are removed and at the same time the screw surface is activated and so N atoms easily penetrate and diffuse when nitriding to form a uniform nitrided layer.

摘要： There is disclosed high-purity nitrogen gas production equipment for production of ultra-high-purity nitrogen gas for use in the electronics and other industries, for example in connection with the production of silicon semiconductors. The conventional nitrogen gas production equipment of cryogenic air separation type tends to develop troubles and yields product nitrogen gas only at high cost and in comparatively low purity. The equipment according to the invention is such that a liquid nitrogen storage means (23) is connected via a first feeding pipeline (24a) to a distillation column (15) into which air is introduced from the outside via an air compression means (9) and heat exchange means (13), (14) while the above storage means (23) is also connected via a second feeding line (24b) to the above heat exchange means (13), (14). In this way, the raw material air is chilled to a cryogenic temperature as a result of absorption of the latent heat of evaporation by liquid nitrogen in the heat exchangers and the cryogenic compressed air is further chilled in the distillation column (15 ) by the heat of evaporation of liquid nitrogen. By taking advantage of the difference in boiling point, the nitrogen is withdrawn in gaseous state while oxygen is retained in liquid state. The resulting nitrogen gas is combined with the vaporized liquid nitrogen originating from the liquid nitrogen storage tank (23) to give product nitrogen gas. By these features, low-cost, high-purity nitrogen gas can be produced without machine troubles.

摘要： A crank shaft is constructed only at the surface layer of a journal portion with a hard nitride layer, so that the resultant crank shaft is available at a low cost, not so heavy and excellent in durability in comparison with a case employing a hard material for the whole crank shaft. Also, a method of manufacturing a crank shaft according to the present invention employs fluorinating process prior to nitriding process to change a passive coat layer, such as oxide layer on the surface of the journal portion to a fluoride layer, which protects the same surface. Therefore, even when there is space of time between formation of fluoride on the surface of the journal portion and nitriding process, the fluoride layer protects and keeps the surface of the journal portion in a favorable condition, resulting in that re-formation of oxide layer on that surface is prevented.

摘要： A process for manufacturing rolled articles of titanium material comprising steps of contacting heated titanium material with fluorine- or fluoride-containing gas to form a fluoride layer on the surface of the titanium material, removing the fluoride layer formed thereon just before rolling and then rolling the titanium material to give a rolled article. With this structure, passive coat layers, such as the oxide layer on the surface of the titanium material is changed to a fluoride layer. The fluoride layer protects the surface of the titanium material. Therefore even if there is space of time between formation and removal of the fluoride layer, the fluoride layer formed on the surface of the titanium material protects the same surface in a favorable condition, which results in preventing re-formation of an oxide layer on the titanium material surface.
