Title: Magnetic head
Inventor: TOURIYUU KOUJI
IPC: G11B5/29
Filed: 1993-03-23
Abstract: PURPOSE:To remarkably reduce an external inductive noise by sufficiently reducing a gap between the tip part of a magnetic cut-off plate and a magnetic shield case than the gap between the tip part of a magnetic core part and the magnetic shield case. CONSTITUTION:The gap B between the tip part 5 of the magnetic cut-of plate 2 and the magnetic shield case 4 is set sufficiently smaller than the gap A between the tip part 6 of the magnetic core 1 and the magnetic shield case 4. Then, since an external noise magnetic flux H is transmitted more to the magnetic cut-off plate 2 as shown by the magnetic fluxes h1, h2, h3, and is transmitted not much to the magnetic core as shown by the magnetic fluxes H1, H2, H3, H4, the noise magnetic flux passing through an electromagnetic conversion coil (not shown in gigure) is reduced, and a noise reproducing amount is reduced. In such a manner, by sufficiently bringing the magnetic cut-off plate 2 between tracks nearer to the magnetic shield case 4 than the magnetic core 1, the external inductive noise is reduced remarkably without increasing a manufacturing cost.

Title: Recovering method for noble metal from used catalyst
Inventor: KURODA ATSUSHI
IPC: C01G55/00
Filed: 1980-05-12
Abstract: PURPOSE: To recover a noble metal from a used catalyst having the metal supported on a porous inorg. substance in a high recovering yield while preventing the carrier from being leached out by subjecting the catalyst to oxidation and reduction at a regulated temp. followed by extraction with an inorg. acid.  
     CONSTITUTION: When a noble metal such as a Pt group element is recovered from a used catalyst having the metal supported on a porous inorg. substance such as activated alumina, the catalyst is calcined at ≥1,000°C in an oxygen atmosphere to remove stuck org. matter by oxidation. In order to reduce the noble metal oxidized by the operation, the catalyst is reduced at ≥200°C in a hydrogen atmosphere, and then extraction is carried out with an inorg. acid such as aqua regia to efficiently recover the noble metal. By raising the calcining temp. to ≥1,000°C, the carrier such as alumina is prevented from being leached out during the extraction, and the recovering process is simplified, resulting in an enhanced recovering yield.
