摘要： Provided is a high-performance PVA fiber and its production.Each filament of the PVA fiber of the present invention having a structure comprising an aggregate of substantially innumerable fibrils, the fiber has high strength, elastic modulus, and resistances to fatigue, hot water and chemicals and can be pulpified while keeping its excellent features such as high strength. The PVA fiber of the present invention cannot, even drawn to a high ratio, be readily whitened by virtue of its fibril-aggregate structure, and can hence be made still higher in performances. The PVA fiber can be obtained by adding to a PVA solution a relatively large amount of surface active agent, and wet or dry-jet-wet spinning the thus prepared dope solution into an aqueous alkaline coagulating bath.

摘要： An active carbon produced from an infusible carbonaceous material as a raw material, which active carbon when used for prevention of automobile fuel evaporation, etc., would not cause any trouble attributed to dust generation, exhibiting reduced pressure loss; and a process for producing the same. There is provided a spherical active carbon produced from an infusible solid carbon material as a raw material, wherein providing that x represents an average particle diameter (mm) and y an MS hardness (%), when x is in the range of 0.5 to 20, y is ≧100×(1-0.8×1.45(0.3-x)). This spherical active carbon can be produced by a process comprising mixing a carbon material with a carbonizable binder; extruding the mixture into a strand form; carrying out rolling granulation so as to obtain a spherical form; rendering the same infusible under appropriate conditions corresponding to the particle size; and performing carbonization and thereafter activation under conditions appropriately restricting the contact with activation gas.

摘要： It is a metal oxidation treatment apparatus for carrying out the inactivation treatment of metal tubes used especially in a super high purity gas piping system and an apparatus of super high vacuum.The support part of a support member is made as a tubular form member, and a tapered part is provided on the outer periphery thereof, and further, since a spring is mounted to be displaceable, even if fluctuation is present in the internal diameter of stainless steel tubes, it is possible to let the stainless tubes easily be supported on the support part. Also, even fluctuation of the length is present in the stainless steel tubes, the support member is always pushed to the stainless steel tubes. Oxidative gas diffusing out of the tube to be treated to the outside thereof can be released to the outside of the oxidation treatment furnace without letting it contact to the tube to be treated.

摘要： When a process gas obtained by mixing a source gas with a diluting gas is supplied to a predetermined process apparatus, by supplying the process gas to the predetermined process apparatus through a gas contacting part connecting at least one source gas supplying pipe with at least one diluting gas supplying pipe, no chance that the source gas is exposed to air contamination is provided. Moreover, in particular, by forming the gas contacting part which is to be in contact with the above source gas, diluting gas and the like using such a material as metal, ceramic or the like, emission of materials having bad influences on the process gas, such as organic materials in particular, is eliminated. Furthermore, by providing a branching pipe or exhausting pipe, the degree of diluting the source gas can be varied stepwise, and by further combining with a flow rate adjuster, it can be varied continuously.
