  • Publication number: 20130143072
    Abstract: A soft magnetic under layer has a low antiferromagnetic coupling force and a high saturation magnetic flux density. The soft magnetic under layer includes two soft magnetic layers and a spacer layer. The soft magnetic layers are expressed by a composition formula as (Fe100-XCoX)100-Y-MY by atomic ratio, wherein 15?X?30, 10?Y?30, and an element M is at least one element selected from a group of Ta, Ti, Zr, Nb, Cr, and B; are composed of residual incidental impurities; and each have a thickness of 10 to 50 nm. The spacer layer is composed of one element selected from a group of Ru, Cr, Cu, Re, and Rh and has a thickness of 0.10 to 0.50 nm. The soft magnetic layers are antiferromagnetically coupled through the spacer layer inserted therebetween. An antiferromagnetic coupling force between the soft magnetic layers is 100 to 4,000 A/m.

  • Patent number: 8422897
    Abstract: By using a black-image forming device, an abrasive pattern is formed on a sheet conveying belt so that toner is input to a contact section where a cleaning blade is in contact with the sheet conveying belt. After the toner is input to the contact section where the cleaning blade is in contact with the sheet conveying belt and then the sheet conveying belt makes one or more revolutions, a process control is performed in which Y, M, and C toner patterns and B toner pattern are transferred onto the sheet conveying belt.

  • Patent number: 6153546
    Abstract: This ultralow-loss glass is characterized in that high purity silica glass contains 1 to 500 wt.ppm of at least one network modifying oxide. It is assumed that the network modifying oxide appropriately loosens the tetrahedral network structure of silica and hence Rayleigh scattering is decreased. Examples of the network modifying oxide include Na.sub.2 O, K.sub.2 O, Li.sub.2 O, MgO, CaO, and PbO. Since Rayleigh scattering losses are minimal in comparison with those of high purity silica glass, this impurity-added silica glass is excellent as a base material of a glass fiber for a long-distance transmission.
