    • In order to determine the seismic vulnerability of a structure, a vibration sensor is placed on each of the top surface of a layer of the structure and the ground surface near the structure so as to record vibrations. A seismic vulnerability data processor assumes a transfer function of vibration of the top surface of the layer of the structure based on a spectral ratio between the vibration recorded on the top surface of the layer of the structure and the vibration recorded on the ground surface, thereby obtaining a predominant frequency and amplification factor of vibration of the top surface of the layer of the structure. A seismic vulnerability index of the layer of the structure resulting from a deformation of the layer is obtained based on the obtained predominant frequency and amplification factor of vibration of the top surface of the layer of the structure and on the height of the layer of the structure. This seismic vulnerability index is multiplied by an assumed seismic acceleration so as to obtain a maximum shear strain of the layer of the structure upon being subjected to an earthquake.
    • 为了确定结构的地震脆弱性,将振动传感器放置在结构的层的顶表面和结构附近的地表面上,以便记录振动。 地震脆弱性数据处理器基于记录在结构层的顶表面上的振动与记录在地面之间的振动之间的光谱比,假定结构层的顶表面的振动的传递函数,由此 获得结构层的顶表面的振动的主要频率和放大系数。 基于获得的结构层的顶表面的振动的主要频率和放大系数以及结构层的高度,获得由层的变形产生的结构层的结构层的地震脆弱性指数 。 该地震脆弱性指数乘以假定的地震加速度,以便在遭受地震时获得该结构层的最大剪切应变。

    • The object of the present invention is to provide a DRAM, in which the operation speed for a sense amplifier can be increased. Bit line precharging circuits PCt and PCb are arranged to precharge bit lines BLt and /BLt to a ground voltage GND, and reference word lines RWLo and RWLe and reference memory cells RMC are arranged, so that when a word line WL is activated, a potential difference is always generated between the bit lines BLt and /BLt. The sources of transistors N10 and N11 of an N-type sense amplifier NSAt are connected directly to a ground terminal GND, and the sources of transistors P2 and P3 of a P-type sense amplifier PSA are connected directly to a power source VDD. The gates of the transistors N10 and N11 are connected to the bit lines /BLt and BLt, and the drains are connected to the bit lines BLt and /BLt, respectively. Shift word lines SWL and shift memory cells SMC are arranged, so that the N sense amplifier NSAt can amplify the potential difference between the bit lines BLt and /BLt.

    • A resist film is formed on the surface of a magnetic layer on a substrate. A die is overlaid on the surface of the magnetic layer. The die includes magnetic and non-magnetic regions alternately arranged on a flat surface around a groove. The resist film is embossed so that the flat surface drives the resist film into the groove of the die. The resist film within the groove gets solidified while the die is kept in contact with the magnetic layer. A magnetic field is applied to the die in contact with the magnetic layer. A magnetic field leaked out of the magnetic regions acts on the magnetic layer. Magnetic information is thus written into the magnetic layer based on the leaked magnetic field. A recording track can be established in the magnetic layer based on the solidified resist film.
    • 在基板上的磁性层的表面上形成抗蚀剂膜。 模具覆盖在磁性层的表面上。 模具包括交替地布置在围绕凹槽的平坦表面上的磁性和非磁性区域。 抗蚀剂膜被压花,使得平坦表面将抗蚀剂膜驱动到模具的凹槽中。 凹槽内的抗蚀膜被固化,同时模具与磁性层保持接触。 将磁场施加到与磁性层接触的模具。 从磁性区域漏出的磁场作用在磁性层上。 因此,磁信息基于泄漏的磁场被写入磁层。 可以在基于固化的抗蚀剂膜的磁性层中建立记录轨迹。
