  • Publication number: 20020012812
    Abstract: A spin valve thin-film magnetic element has an improved rate of change in resistance (&Dgr;R/R) that can be used for a narrower magnetic track. The spin valve thin-film magnetic element has a laminate that include an antiferromagnetic layer, a pinned magnetic layer, a non-magnetic conductive layer, a free magnetic layer, a back layer, specular-reflection layers and a pair of electrode layers formed at the two sides of the laminate. Preferably the specular reflection layer includes an oxide, such as &agr;-Fe2O3 or NiO, or a half-metal Heusler alloy, such as NiMnSb or PtMnSb.

  • Patent number: 6330132
    Abstract: A magnetic head comprises a bump electrically connected to a head element on a side wall of a slider, and a pad covering a protective layer and a contact area of the bump exposed from an flat surface of the protective layer. In the magnetic head, since a bonding member for bonding a conductive pattern to the pad is bonded in a bonding area of the pad formed on the protective layer, secure bonding can be obtained regardless of the form of the contact area of the bump, and a highly reliable magnetic head, without bonding defects, can therefore be provided.

  • Publication number: 20010012188
    Abstract: A spin-valve thin-film magnetic element includes a substrate, a composite formed thereon, and electrode layers formed on both sides of the composite. The composite includes an antiferromagnetic layer, a pinned magnetic layer, a nonmagnetic conductive layer, a free magnetic layer, a mean-free-path-extending layer, and an exchange bias layer. The mean-free-path-extending layer may be a back layer or a mirror reflective layer. The mean-free-path-extending layer extends the mean free path of spin-up conduction electrons in the spin-valve thin-film magnetic element. This spin-valve thin-film magnetic element meets trends toward a narrower track width.

  • Patent number: 6263565
    Abstract: A through hole 5 formed in a substrate and having an electrode film on an inner surface thereof is cut and divided into two through holes or blind holes each of substantially semicircular arc shape through dicing processing using a rotating blade, and one of the-divided through holes 5 of substantially semicircular arc shape is used as an external connection terminal 3 of substantially semicircular concave arc shape thereby to form a surface mounted electronic parts having a plurality of the external connection terminals 3.

  • Patent number: 6059067
    Abstract: A feed-forward control section controls, in a feed-forward manner, left and right hydraulic clutches C.sub.L and C.sub.R of a driving force distributing device by presuming such a driving force distribution amount .DELTA.T that a yaw rate corresponding to a turning state of a vehicle is obtained, based on an engine torque, an engine revolution-number, a vehicle speed, a steering angle and a lateral acceleration. On the other hand, a feedback control section calculates a deviation between a reference yaw rate calculated from the vehicle speed and the lateral acceleration and an actual yaw rate detected by a yaw rate sensor, and corrects the driving force distribution amount .DELTA.T calculating in the driving force distributing device in order to converge the deviation into zero.

  • Patent number: 5893812
    Abstract: A driving force distributing device is provided for distributing a driving force of an engine to the left and right wheels of a vehicle by bringing a pair of hydraulic clutches into and out of their engaged states. The distributing device includes a hydraulic pump mounted within a casing thereof and driven through gears by a half shaft connected to one of the wheels. An oil passage interconnects the hydraulic pump and the hydraulic clutches, the oil passage being defined in a casing. A valve block is coupled to an upper surface of the casing. Thus, the oil passages interconnecting the hydraulic pump and the hydraulic clutches of the driving force distributing device can be compactly formed.
