摘要： A method and apparatus for continuously withdrawing an elongated product such as from a melt a fine wire is based on the rotating liquid medium spinning method. A layer of cooling liquid (14) is centrifugally formed on the inner peripheral surface of a rotational drum (13). Disposed inside the rotational drum (13) is a winding reel (19) having a rotating winding peripheral surface (18). A holder element (20) adapted to be magnetically attracted to the winding peripheral surface (18) is initially placed on the inner peripheral surface of the rotational drum (13). A molten material injected into the drum by a nozzle (16) is quenched for solidification in the cooling liquid (14) to form the product. Initially, the leading end emerging from the nozzle rides over the holder element (20) which then carries the leading end onto the winding peripheral surface (18) and holds it thereon by magnetic attraction. The product (17) is then wound on the winding peripheral surface (18) with its portion fixed by the holder element (20 ) serving as the winding starting end.

摘要： Leaks from a hollow fiber membrane module comprising a housing having one or more hollow fiber bundles positioned therein with at least one end of each bundle being sealed by a cementing layer includes the step of applying a pressurized gas to the external surfaces of the hollow fibers. The gas which is used must have a refractive index different from the refractive index of the ambient atmosphere. The atmospheric volume adjacent the sealed end of the module is optically monitored for refraction patterns caused by gas leaking through the sealed end into the volume. The optical system includes a light source and components for directing light from the source along an optical path including the monitored volume. Light which is passed through the monitored volume is directed to an optical display where the refraction patterns of the leaking gas will be visible. The method and apparatus permit leaks to be located without the use of liquids.

摘要： A T-type circuit having series resistors and a parallel resistor is arranged on the outside of an amplifier, a signal is amplified in the amplifier while stabilizing the signal by using the T-type circuit functioning as a stabilizing circuit, and the amplified signal is output. In this case, values of the series resistors and the parallel resistor of the T-type circuit are determined so as to set an output load impedance obtained by seeing the output side of the high-frequency amplifier from the amplifier to a value near to or slightly lower than a value of the conjugate complex impedance of an output impedance of the amplifier. Therefore, the output signal having a high output electric power and a low distortion can be obtained in the high-frequency amplifier while keeping a gain and a noise characteristic of the high-frequency amplifier.

摘要： The present invention relates to a method of producing a superconducting composite wire. The method comprises forming a continuously supplied metal or metal alloy strip into a flume-shaped strip. A ceramic copper oxide superconducting powder material is filled in the interior of the flume-shaped strip. The flume-shaped strip is rolled such that a first edge of the strip approaches a second edge of the strip to form a tubing having a gap between the first and second edges and also having the powder material enveloped therein. The gap allows free access of oxygen to the powder material during a subsequent sintering step. The powder material is then sintered at a temperature of between 0 and 100.degree. C. less than the lowest melting point of any constituent of the material. The strip enveloping the sintered material is then deformed to a reduced cross-section and subjected to a heat treatment.
