    • A magnetic pattern of a master disc is transferred to both sides of a magnetic recording medium with no displacement. The origin of a magnetic recording medium can be determined by observing the inner or outer periphery of the magnetic recording medium. Back-side alignment marks are formed on the front side of the magnetic recording medium based on the origin thus determined. The back-side alignment marks can be observed with a microscope and front-side alignment marks for the magnetic recording medium can be provided on the back side of the magnetic recording medium. The alignment marks provided on the front/back sides of the magnetic recording medium are aligned with the corresponding alignment marks provided on the master disc, and a magnetic pattern formed on the soft magnetic material of the master disc is can be transferred to the magnetic recording medium.
    • 母盘的磁性图案被转移到没有位移的磁记录介质的两侧。 可以通过观察磁记录介质的内周或外周来确定磁记录介质的原点。 基于这样确定的原点,在磁记录介质的前侧形成背面对准标记。 可以用显微镜观察背面对准标记,并且可以在磁记录介质的背面设置用于磁记录介质的前侧对准标记。 设置在磁记录介质的前/后侧的对准标记与设置在母盘上的对应对准标记对准,并且形成在母盘的软磁性材料上的磁图案可以被传送到磁记录 中。

    • A method for manufacturing a master disk for magnetic transfer, with which a soft magnetic material can be evenly embedded in the grooves of a master disk. A patterned groove is formed on the main surface of a silicon substrate, which is the substrate of a magnetic transfer master disk. A conductive thin film is formed on the main surface of the silicon substrate and the groove surfaces. With this conductive thin film as one electrode, a plating film of a soft magnetic material is deposited on the main surface of the silicon substrate and inside the grooves, on the bottom and sidewalls thereof, by electroplating. Then, just the soft magnetic material deposited on the main surface of the silicon substrate is removed by CMP, causing the soft magnetic material in the interior of the grooves to remain.
    • 一种用于制造用于磁转移的母盘的方法,通过该方法可以将软磁材料均匀地嵌入母盘的凹槽中。 在作为磁转移母盘的基板的硅衬底的主表面上形成图案化的槽。 在硅衬底的主表面和沟槽表面上形成导电薄膜。 利用该导电性薄膜作为一个电极,通过电镀将软磁性材料的镀膜沉积在硅衬底的主表面上以及凹槽的内侧,底部和侧壁上。 然后,仅通过CMP去除沉积在硅衬底的主表面上的软磁材料,使得凹槽内部的软磁材料残留。

    • past positions of a plurality of composing elements indicated by various past arrangement examples are given to each potential function corresponding to one composing element, and parameter values of the potential functions corresponding to the composing elements are automatically set on condition that a past total potential energy obtained by solving the potential functions is minimized. Thereafter, the parameter values are given to the potential functions in which a position of any composing element is not determined, and particular positions of the composing elements are determined on condition that a total potential energy obtained by solving the potential functions is minimized. Because each potential function corresponding to one composing element has an attraction term indicating the attraction between the composing element and the other composing elements and an attraction-repulsion term indicating the setting of the composing element at a position spaced at moderate distances from the other composing elements, the particular positions of the composing elements are set in an optimum arrangement. Accordingly, the optimum arrangement of the composing elements can be automatically obtained without extracting any arrangement knowledge from a skilled person.
    • 对于与一个构成要素相对应的各个电位函数,赋予由各种过去的配置例子指示的多个组成元素的过去位置,并且在获得的过去总势能的条件下自动设置与组成元素相对应的潜在函数的参数值 通过解决潜在的功能最小化。 此后,将参数值赋予未确定任何组成元素的位置的潜在功能,并且在通过求解潜在功能获得的总势能最小化的条件下确定组成元件的特定位置。 由于与一个构成要素对应的每个潜在功能具有表示构成要素与其他构成要素之间的吸引力的吸引项,还具有表示构成要素在与其他构成要素间隔中距离的位置的设定的吸引力排斥项 ,组合元件的特定位置被设定为最佳布置。 因此,可以自动获得组合元件的最佳布置,而不需要从技术人员那里提取任何安排知识。

    • A vibration type measuring instrument measures at least one of a mass flow rate and a density of a fluid flowing through a straight measurement pipe by vibrating the measurement pipe, obtains a frequency ratio of a resonant frequency of a first vibration mode to a resonant frequency of a second vibration mode of the measurement pipe, and corrects a measured value of at least one of the mass flow rate and the density according to the frequency ratio. The instrument includes a first vibration detector for detecting at least one of a vibration generated in the measurement pipe depending on the mass flow rate and the resonant frequency of the first vibration mode of the measurement pipe; and a second vibration detector for detecting the resonant frequency of the second vibration mode of the measurement pipe. The second vibration detector is provided around an antinode of the second vibration mode of the measurement pipe to improve the detection sensitivity in the second vibration mode.
