Abstract: PURPOSE: To easily discriminate particular portions from the outside by fixing a magnetizable metallic material within a small limited range in an axial direction between the two particular portions before at least one constituent of a core wire is covered with a protecting jacket, and putting marks on the particular portions via a sensor responsive to the metallic material after completion. CONSTITUTION: A conductive wire 3 is supplied to a station 10, where a metallic material 8 or 9 is fixed to the conductive wire 3. The conductive wire 3 to which the metallic material is fixed is carried to a next station 11. The conductive wire 3 becomes a core wire 12 after it goes out of the station 11, and then, it is covered with a protecting jacket 4 by an extruder 13.

Filed: 1987-09-21
Abstract: PURPOSE:To prevent the generation of unauthorized copy by comparing two coded data read out by respective coded data readers in two medium driving devices, and only when both data coincide with each other, allowing copying between two media. CONSTITUTION:A copying source medium 4a in which original information is written and a copied medium 4b in which information is to be copied are prepared.
