摘要： A method of producing carbon fibers in which an exhaust gas generated in a heat-treating stage of the production of carbon fibers is divided into two portions, one portion thereof being decomposed by the action of an oxidizing catalyst and subsequently being blended with the other portion, to be reused. According to said method, the heat loss in the exhaust gas disposal process can be substantially reduced and the efficiency of heat-treating can be improved and in consequence, various troubles due to the decomposed products contained in the heat-treating atmosphere such as surface damage, fuzziness and individual fiber breakage, etc. can be avoided.

摘要： Disclosed is an improvement in a process for producing oxidized fibers wherein precursor fibers comprised of oxidizable continuous filaments are repeatedly brought into or out of contact with the surface of a heated body, maintained at a temperature of from approximately 200.degree. to 400.degree. C., in an oxidizing gaseous atmosphere thereby to be oxidized. The oxidized fibers can then be heated in a non-oxidizing gaseous atmosphere maintained at a temperature of at least approximately 800.degree. C. to produce carbon fibers, if desired. The improvement resides in that an interlaced filament yarn is used as the precursor fibers, which yarn substantially has no crimps or loops and is comprised of continuous filaments entangled with each other along the longitudinal direction thereof to an extent such that the coherency factor of the yarn is in the range of from approximately 20 to 100.
摘要翻译：公开了生产氧化纤维的方法的改进，其中由可氧化的连续长丝组成的前体纤维与加热体的表面反复进入或不接触，保持在约200-400℃的温度，在氧化气氛中，由此被氧化。然后，如果需要，氧化纤维可以在保持在至少约800℃的温度下的非氧化性气体气氛中加热以产生碳纤维。改进之处在于，使用交织的长丝纱作为前体纤维，该纱线基本上没有卷曲或环状，并且由沿其纵向方向彼此缠结的连续长丝组成，使得纱线的相干因子在约20至100的范围内。

摘要： An overhang type electromagnetic clutch used for selectively connecting the rotation of an internal combustion engine to a compressor for an air conditioning system for an automobile. The clutch is provided with a rotor having a sliding surface axially spaced from an outer end of a pulley arranged around the rotor. A bit, which initially is in contact with the sliding surface at a location spaced from the axis of the rotation of the rotor, is radially moved while the rotor is rotated, so that radially spaced apart tool marks eccentric to the axis of the rotation of rotor and having a gradually increased radius are formed on the entire region of the sliding surface. An increased engagement of the sliding surface with an armature is obtained due to the provision of engagements in the circumferential direction. A bit, which initially is in contact with the sliding surface at a location corresponding to the axis of the rotation of the rotor may be first moved radially outward while the rotor is rotated, so that radially spaced apart first tool marks concentric to the axis of the rotation of rotor and having a gradually increased radius are formed on the entire region of the sliding surface. The bit is then moved radially inward so that radially spaced apart second tool marks concentric to the axis of the rotation of rotor and having a gradually decreased radius are formed on the entire region of the sliding surface. As a result, the first and second tool mark cross and provide an engagement in the circumferential direction.
