  • SI-KILLED STEEL WIRE ROD HAVING EXCELLENT FATIGUE PROPERTIES, AND SPRING USING SAME
    Publication number: 20150369322
    Abstract: This Si-killed steel wire rod has Si-killed steel which contains specific chemical components that contain, as 80% or more of the number of inclusions, specific CaO—Al2O3—SiO2 inclusions, wherein the average composition of the MnO—Al2O3—SiO2 inclusions that satisfies the following (3A) satisfies the following (3B). (3A) If CaO+Al2O3+SiO2+MgO+MnO serves as the 100% standard, MnO+Al2O3+SiO2?80%, MnO>CaO. (3B) When CaO+Al2O3+SiO2+MgO+MnO serves as the 100% standard, MnO: 10 to 70%, Al2O3: 3 to 50%, SiO2: 20 to 75%.

  • Method and apparatus for providing selective write protect regions in a storage medium
    Patent number: 6289423
    Abstract: A method and apparatus to control copying of a group of data stored in an original information-storing medium into a destination information-storing medium. The method includes a step of reading attribute information of a first zone storing the group of data, where the attribute information indicates whether the zone is a ROM area or a RAM area, and a step of copying the attribute information to a second zone to which the group of data is to be copied. The method further includes a step of copying the group of data stored in the said first zone in the original information-storing medium to the second zone in the destination information-storing medium.
