  • Patent number: 12133394
    Abstract: A magnetic memory device including a first memory cell which includes a first stacked structure including a magnetic layer and a second memory cell which is provided on the first memory cell and includes a second stacked structure including a magnetic layer. Each of the first stacked structure and the second stacked structure includes a first magnetic layer having a variable magnetization direction, a second magnetic layer having a fixed magnetization direction, and a nonmagnetic layer provided between the first magnetic layer and the second magnetic layer. A concentration of iron (Fe) contained in the first magnetic layer included in the first stacked structure and a concentration of iron (Fe) contained in the first magnetic layer included in the second stacked structure are different from each other.

  • Patent number: 7659114
    Abstract: An attenuated feline recombinant herpesvirus 1 (FHV-1), which is prepared by identifying gene regions in the genome wherein inserted foreign genes can be expressed without affecting the replication of FHV-1 and has least two types of foreign nucleic acid sequences inserted thereinto, usable as a vector virus or a vaccine. In this attenuated recombinant FHV-1, at least two types of foreign genes are inserted in such a manner as allowing the expression into two different gene regions exerting no lethal effect on the proliferation of the virus in the feline herpesvirus 1 genome.

  • Publication number: 20030164932
    Abstract: A method of determining an exposure value for exposing a resist film, comprises the steps of: estimating a size variation of a resist pattern from a predetermined target size based on a waiting time of a currently processing resist film to be patterned in subsequent sequential exposure and development processes; and compensating a reference exposure value based on said size variation to obtain a compensated exposure value.

  • Patent number: 4998033
    Abstract: A spindle motor comprising a stator including a support shaft positioned on a base, a cap-shaped rotor rotatably and concentrically disposed around the support shaft, thrust and radial bearings disposed between the stator and the rotor, a stator coil secured to the stator, and a rotor magnet member secured to the rotor opposing the stator coil. The thrust and radial bearings are hydrodynamic bearings. A movable piece that constitutes a part of the thrust bearing is secured to the lower end of a cylindrical portion of the rotor and extended outwardly or inwardly from the cylindrical portion, or is disposed above the rotor. The stator coil is secured to the outer peripheral portion of the support shaft above or below the radial bearing. The rotor magnet member is securd to the inner peripheral surface or inner top surface of the rotor. Either a radial or axial gap is provided between the stator coil and the rotor magnet member.
