  • Publication number: 20150070302
    Abstract: In an electronic device, a processor determines whether there is one touch region or two or more touch regions touched in a first region existing in an outer periphery portion excluding a central portion of a touch panel. Then, in a case where it is determined that there is one touch region, the processor validates the touch operation. In a case where it is determined that there are two or more touch regions, the processor invalidates the touch operation.

  • Publication number: 20090141410
    Abstract: An electrically-conductive or insulating non-magnetic intermediate layer is inserted between a free magnetic layer and a pinned magnetic layer in a current-perpendicular-to-the-plane (CPP) structure magnetoresistive element. At least one of the free magnetic layer and the pinned magnetic layer is made of a nitrided magnetic metal alloy. This nitrided magnetic layers allows the CPP structure magnetoresistive element to enjoy an increased magnetoresistance change (?RA). In addition, the saturation magnetic flux density (Bs) decreases in a nitrided magnetic metal alloy. The inversion of magnetization is thus easily caused in the low Bs magnetic layer. The detection sensitivity of the CPP structure magnetoresistive element is improved. The CPP structure magnetoresistive element is thus allowed to detect magnetic bit data with higher accuracy.

  • Patent number: 7486487
    Abstract: A magneto-resistive element employs a CPP structure and includes an antiferromagnetic layer, a pinned magnetization layer, a nonmagnetic intermediate layer and a free magnetization layer that are successively stacked. The pinned magnetization layer includes a first pinned magnetization layer, a nonmagnetic coupling layer and a second pinned magnetization layer that are successively stacked on the antiferromagnetic layer, and the first and second pinned magnetization layers are antiferromagnetically exchange-coupled. One of the first and second pinned magnetization layer is formed by a ferromagnetic layer made of a ferromagnetic material at least including one element or alloy selected from a group consisting of Co, Fe, Ni and alloys thereof, and the other is formed by a resistance control layer made of a conductive ferromagnetic oxide.
