Title: Nd-fe-b based permanent magnet
Inventor: TAKAHASHI MASAHIRO
IPC: H01F1/08
Filed: 1993-03-17
Abstract: PURPOSE:To provide a title magnet having a maximum energy product (BH)max of 42MGOe or more and a coercive force iHc of l2KOe or more. CONSTITUTION:An in-field press-molded compact of a powder obtained from an ingot of the composition of Nda-Dyb-B1.05-Nb0.60-Gac-Al0.20-Feba1(wt%) is sintered at 1080 deg.C X 3hr sintering under vacuum and heat-treated at 900 deg.C X2hr, 530 deg.C x 2hr, so that a sinter of 7.55-7.58g/cc density, 1100-4000ppm oxygen content is obtained. An examination result of the relation Nd content between magnetic characteristics with Dy=l.0wt%, Ga=0.06wt.% with regard to that sinter shows that coercive force iHc increases with an increase in Nd content, but residual flux density Br decreases, and that lowering Dy + Nd content down to 32wt.% or less by complex addition of Nd, Dy, Ga can provide an excellent maximum energy product (BH)max and coercive force.

Filed: 1986-04-11
Abstract: PURPOSE:To ensure circuit operation of an integrated circuit to a surge voltage by providing diodes connected in series in reverse direction between an input terminal and a high-potential side power source in a TTL integrated circuit device. CONSTITUTION:A negative surge voltage which was applied to an input terminal is absorbed by a low-potential side power source terminal 4 through a diode 3 formed in an integrated circuit 7. When a positive surge voltage is applied to the input terminal 1, it is absorbed by a high-potential side terminal 5 through a diode 8 and the diode 2 by breakdown of the diode 8. A breakdown voltage of the diode 8 is made lower than that of the diode 3. The breakdown voltage is adjusted by changing a concentration in a P-N junction.
