Title: Manufacture of oxide superconducting wire
Inventor: IKENO YOSHIMITSU
IPC: H01B12/04
Filed: 1987-10-28
Abstract: PURPOSE:To enable obtaining an oxide superconducting wire of high mechanical strength by housing a green compact in a metal sheath for forming a complex body and applying a diameter reduction process to the complex body and then heat treatment thereto. CONSTITUTION:A round bar-shaped green compact 1 is obtained by applying a pressed powder formation process to superconducting powder having a grain diameter of 1mum or less. The green compact 1 after sintering treatment is housed in a metal tube body 2 and a complex body 3 is prepared. The complex body 3 is reduced in diameter while being subjected to a forging process in turn from one end thereof. The diameter is reduced to a two-dot chain line and a complex body 13 is obtained. By this diameter reduction process, the compaction of the green compact 1 in the complex body 13 can be made equal to or more than 75% of theoretical compaction. Thereafter, the tube body part forming an outer metal sheath is removed and the green compact 1 is thereby exposed. And the exposed green compact 1 is subjected to final sintering treatment. According to the aforesaid process, it is possible to generate a compact superconductor of extremely low porosity and, therefore, a superconducting wire of high mechanical strength can be obtained.

Abstract: PURPOSE: To realize a digital video tape recorder of a narrow track pitch by exposing a magnetic recording medium provided with a magnetic layer on a nomnagnetic substrate to an atmosphere of >=50 deg.C and extremely minimizing the tension loaded on this magnetic recording medium. CONSTITUTION: The position of the lowermost part of the coating type magnetic recording medium 20 is detected by a position detecting sensor and the position of the lowermost part thereof is detected by a take-off roller 39 and a take-off press roller.
