    • A semiconductor integrated circuit device includes a processor, a first clock generating section and a control section. The processor core operates in synchronism with a first clock and includes first and second critical paths. The first clock generating section controls a duty of an externally input second clock to generate the first clock. a control section detects a first phase difference between the first clock and a third clock obtained by delaying the first clock by a delay time in the first critical path and a second phase difference between the first clock and a fourth clock obtained by delaying the first clock by a delay time in the second critical path. The control section instructs the first clock generating section to control the duty so as to minimize a difference between the first and second phase differences.
    • 半导体集成电路器件包括处理器,第一时钟产生部分和控制部分。 处理器核与第一时钟同步操作,并且包括第一和第二关键路径。 第一时钟产生部分控制外部输入的第二时钟的占空比以产生第一时钟。 控制部分检测第一时钟与通过将第一时钟延迟第一关键路径中的延迟时间而获得的第三时钟之间的第一相位差,以及通过延迟第一时钟而获得的第一时钟与第四时钟之间的第二相位差 在第二个关键路径中延迟时间。 控制部分指示第一时钟产生部分控制占空比,以使第一和第二相位差之间的差最小化。

    • A magnetic transferring apparatus allows attachment of a first magnet to a first holder. A second magnet is attached to a second holder. The first and second holders are located in a space between first and second magnets. A magnetic disk and a master member are located in a space between the first and second holders. The magnetic attraction is generated between the first and second magnets. The magnetic attraction serves to bring the first and second holders closer to each other, so that magnetic pieces of the master member is brought in a close contact with the magnetic disk between the first and second holders. The magnetic flux runs between the first and second based on the contact between the magnetic pieces and the magnetic disk. A servo pattern can in this manner be established in the magnetic disk.
    • 磁转移装置允许将第一磁体附接到第一保持器。 第二磁体连接到第二支架。 第一和第二保持器位于第一和第二磁体之间的空间中。 磁盘和主构件位于第一和第二保持器之间的空间中。 在第一和第二磁体之间产生磁吸引力。 磁吸引用于使第一和第二保持器彼此靠近,使得主构件的磁片与第一和第二保持器之间的磁盘紧密接触。 基于磁片和磁盘之间的接触,磁通量在第一和第二之间延伸。 这样可以在磁盘中建立伺服模式。
