    摘要： A process of continuous production of seam-welded steel tubing is concerned.A steel strip is taken out from a strip coil and conveyed to a tube-preshaping step including a plural of shaping roll stand positions. In the preshaping step, the strip is laterally rounded up gradually from band strip to a rough-shaped tubing until the side edges are brought into a mutually abutting state ready for seam-welding. The preshaping step is divided into a plurality of local regions. In these local regions, substantially body portion with exception of corresponding marginal edge zones of the tubing stock is separately subjected to heating. The heating width and heating intensity at these regions are increased stepwise as the tubular stock advances from upstream to downstream for avoiding conventionally appearing edge wavings and buckling undulations in the material of the steel tubing.

    摘要： A high pressure injection nozzle member is formed of a super hard alloy or a hard material of carbide series mainly composing of a tungsten carbide as, wherein the tungsten carbon is composed of grains each having a diameter of less than 1 .mu.m. At least one kind of carbide or solid solution of carbide selected from Ti, Ta, V, Cr, Mo, Hf, or Zr by a weight % of less than 10.0% is added. A binding material essentially consisting of at least one of iron group elements by weight % of 0.2 to 2.0% may be further added. The super hard alloy or a hard sintered material has a high abrasion proof property and has a hardness more than about HRA 94.0. Nitride or nitride solid solution may be utilized in place of carbide or carbide solid solution. The nozzle member is particularly suitable for an abrasive water jet.

    摘要： A composite structure is manufactured by joining a first material, preferably made of a magnetically permeable material and having a first joining surface in which a recess having an overhang surface is formed, to a second material preferably made of an electrically conductive material and having a second joining surface to be joined to the first joining surface of the first material. On the second joining surface is integrally formed a protrusion having an outer configuration substantially corresponding to the inner shape of the recess. The first and second materials are firmly mechanically joined to each other by, for example, a casting method, a rolling method, a pressing method, or a method utilizing plastic flow of the second material.

    摘要： A fatty acid ester of cellulose having excellent transparency, filterability and spinnability in spite of its high content of mannose and xylose, wherein the total molar content of mannose and xylose accounts for at least 7% of that of glucose, mannose and xylose, and the amount of filtration satisfies a specified requirement. Such a fatty acid ester of cellulose is prepared by using a pulp having a low .alpha.-cellulose content as a raw material and a fatty acid corresponding to the ester as a diluent and adding an organic solvent in an amount of at least 10% by weight based on the diluent in any step during the preparation. In the preparation of cellulose diacetate, which excellent filterability and transparency, by the acetic acid process, the cellulose diacetate obtained by aging is dissolved in a solvent which can dissolve it and the resulting cellulose diacetate is recovered.

    摘要： A tobacco filter is produced by wrapping up a sheet-like filter material having a web structure and comprising a cellulose ester short staple into a rodform. As the cellulose ester short staple, a short staple that is non-crimped and/or has a modified cross section where a ratio D1/D2 of a diameter D1 of the circumscribed circle to a diameter D2 of the inscribed circle, each circle being of the cross section, of not less than 2 is used. The short staple includes e.g. a cellulose acetate fiber with an average fiber length of 1 to 10 mm and fineness of 1 to 10 deniers. The short staple may be incorporated with a beaten pulp with a Schopper-Riegler freeness of 20 to 90.degree. SR and/or a binder. The ratio of the short staple to the beaten pulp may for example be about 90/10 to 20/80 (by weight).

    摘要： A tobacco smoke filter material has a fibrillated cellulose ester fiber with an average fiber diameter of 15 to 250 .mu.m and a BET specific surface area of 0.5 to 4.5 m.sup.2 /g. The fibrous cellulose ester content of the material may for example be not less than 20 weight %. The cellulose ester fiber is provided by, for example, extruding a cellulose ester solution from a nozzle into a precipitating agent for the particular cellulose ester and subjecting the extrudate to a shear force. This filter material can be used in the form of, for example, a filament, web or sheet to provide a tobacco smoke filter which assures good smoking qualities and excellent wet disintegratability.
