Abstract: A tube made of oxygen free copper is filled with a plurality of copper matrix Nb—Ti superconducting lead wires to obtain a composite billet. The resulting billet is subjected to hydrostatic pressure extrusion. Further, ageing heat treatment and wire drawing process are repeated for the composite material three times to prepare a Cu/Nb—Ti superconducting single wire. Then, the resulting Cu/Nb—Ti superconducting single wires are stranded each other to produce a superconducting strand. The superconducting strand is coated with an aluminum alloy to which either a content of 20 to 100 ppm of Cu and Mg or Mg, or a content of 10 to 120 ppm of Si and Cu is added by means of hot extrusion, the strand thus extruded is reduced by 0 to 20% in accordance with cold working to produce an aluminum stabilized superconductor.

Abstract: An image recording system and method for smoothing printed characters, in particular, for low resolution printers. The image recording system includes a font decoding device, a font generating device and a font sizing device. The font decoding device decodes first font data including first character size information and first luminance (optical density) information. The first luminance information has two gradation levels for printing image data. The font generating device generates second font data including second character size information, which is larger than the first character size, based on the first font data. The font sizing device reduces the font of the second font data to the size of the first character and at the same time converts the first luminance (optical density) information using spatial filters into multiple gradations to reduce printed character jaggedness.

Abstract: A method for the homopolymerization or copolymerization of vinyl chloride, wherein the inner wall of the polymerizer and the like are prevented from being fouled with the resulting polymer by applying a coating fluid containing the oxidative polymerization product of a specific phenolic monomer to the surface of the inner wall of the polymerizer and the like, as well as an anti-fouling agent used for this purpose. The method of this invention can very effectively prevent the polymerizer and the like from being fouled with the resulting polymer without affecting the polymerization rate and various properties of the product. Consequently, the necessity of performing the operation for removal of the deposited polymer after completion of each polymerization cycle is eliminated, thus making it possible to achieve closed polymerization requiring no manhole opening after each polymerization cycle which is becoming increasingly popular in recent years.

Abstract: A color image recording device that prevents extreme changes in color at the boundary of the selected color when the hue, value, and chroma are color adjusted selectively but not as a whole. In addition, creating color data for printing does not require large processing time even when a large image is printed. The color image recording device forms color data for printing by adjusting the color of an RGB color decomposition signal of an input device such as a color scanner, or RGB image data from a computer. The color image recording device prints after partially and selectively adjusting color. Furthermore, when converting the RGB data to data unique to the color image printing device, the color image recording device conducts coordinate conversion in the uniform color space and computes a matrix coefficient using the set values of each correction range. Each of the correction amounts of the hue, value, and chroma are set by the operator and the printing characteristic data.
