Abstract: An insulated wire has a conductor, a first insulating metal oxide layer which is formed around the conductor, and a second insulating metal oxide layer, containing ceramic particles mixed by addition and formed around the first insulating metal oxide layer. The so formed insulating metal oxide layers are produced by changing a precursor of a metal oxide into the ceramic state. This change is caused by a method such as a sol-gel method or a thermal decomposition method. The mixed ceramic particles are more preferably in the form of fine platelets. This insulated wire has an excellent flexibility, emits no gas, can maintain its insulation even at a high temperature, and has a high breakdown voltage.

Abstract: A color image processing system includes a color television camera monitoring an object to provide a video signal comprising three primary color components, and a color determination section which defines particular hue, chroma, and brightness regions. The video signal from the camera is analyzed at the color determination section in such a manner as to determine the video signal denotes the particular hue, chroma, and brightness when the three primary color components are found to fall within the particular hue, chroma, and brightness regions, respectively. Thus determined video signal is extracted as forming individual color signals indicating filtered images of the object with regard to the particular hue, chroma, and the brightness, respectively.

Abstract: A solution of a ceramics precursor prepared from at last one or two types of metal alkoxides or metal acylates is applied onto a ceramics film having irregularity on its surface, which is formed on a conductor surface, to fill up irregular portions of the surface. This ceramics precursor solution is at least partially changed to a ceramics state by heating. The surface is smoothed by such application of the ceramics precursor solution, and general disadvantages of weakness against rubbing and inferiority in workability can be improved. Further, it is possible to improve an outgassing property.

Abstract: A method of manufacturing a superconducting wire is carried out by first preparing a material being composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7. This material is melted in a platinum crucible. A melt thus obtained is drawn out from a hole provided on the bottom wall of the crucible to be linearly discharged. The linearly discharged melt is cooled and solidified. A cooling/solidifying space for such a step is set at a temperature less by about 10.degree. C. than the solidifying point of the material, and a slow-cooling zone is provided next to the cooling/solidifying space. This slow-cooling zone is provided to be at a relatively high temperature in a portion closer to the hole while having a temperature gradient along a direction for linearly discharging the melt. A superconducting wire being composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7 is obtained. This superconducting wire superconducts at 85K.

Abstract: 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.
