    • The accuracy of effective channel width extraction in drain current method is improved. There are prepared a transistor with a wide channel width serving as a reference, and a transistor with a narrow channel width that becomes a candidate for extraction (step ST1.1). From the characteristic curve of a plane formed by mask channel width and source-drain conductance, there is extracted a virtual point at which the change of source-drain conductance is estimated to be approximately zero even if the gate overdrive is finely changed. Then, the value of function F is calculated which is defined by the difference between the change of the conductance at the coordinate of the virtual point and the product obtained by multiplying the conductance per unit width by the change of the mask channel width (step ST1.6). From a shift amount (&dgr;) which minimizes the standard deviation of the function F to be obtained (step ST1.7), the true threshold voltage of the transistor with the narrow channel width is determined (step ST1.10).
    • 漏电流法有效沟道宽度提取的精度得到提高。 准备具有宽沟道宽度的晶体管作为基准,并且具有成为提取候选的窄沟道宽度的晶体管(步骤ST1.1)。 从由掩模沟道宽度和源极 - 漏极电导形成的平面的特性曲线,提取虚拟点,即使栅极过驱动被精细地改变,源极 - 漏极电导的变化被估计为近似为零。 然后,计算函数F的值,其由虚拟点的坐标上的电导的变化与乘以每​​单位宽度的电导乘以掩模通道宽度的变化而得到的乘积之间的差定义(步骤ST1 .6)。 根据要获得的函数F的标准偏差最小化的移位量(delta)(步骤ST1.7),确定具有窄通道宽度的晶体管的真实阈值电压(步骤ST1.10)。

    • An electric-powered shutter apparatus to be mounted to a building. A winding drum (4) of an electric-powered shutter device (1) is provided with a driving mechanism including an electric motor (7) and a single-directional rotary clutch device (8). A balance tension device (9) is provided at the other end of the apparatus. The clutch device (8) is configured to slip when the load of the rotation in the direction of the curtain being fed exceeds a certain load. Further, the load at which the clutch device (8) slips is set so as to be greater than the force for forcibly rotating the electric motor when disconnected from electric power. The balancing tension device (9) is balanced against the sum of the weight of the shutter curtain (2) and the load for forcibly rotating the electric motor (7). Thus, the need for a braking device for the electric-powered shutter apparatus to be mounted to a building is eliminated.
