    • Provided is a suturing needle, which can be reliably held by a needle holder, which can transmit a high thrust, and which can reduce the fear of damaging a patient and the deformation when a strong force acts. The suturing needle has a representative constitution including a needle tip portion (1) having a needle tip (1a) for piercing the tissues, a tapered portion (2) continuing to the needle tip portion (1), a trunk portion (3) continuing to the tapered portion (2), and a thread attaching portion (4) continuing to the trunk portion (3) for connecting the suturing thread. The suturing needle is characterized in that the needle tip portion (1) is formed to have a circular section continuing to the sharp needle tip (1a), an angular section continuing to the sharp needle tip (1a), a circular section continuing to the blunt needle tip (1a) or an angular section continuing to the blunt needle tip (1a), in that the tapered portion (2) is formed to become gradually thicker from the needle tip portion (1) to the trunk portion (3), in that the trunk portion (3) is formed to have a substantially triangular section, the upper face of which is formed of a wave shape having at least two ridges and the slopes of which are formed of two flat faces, in that the trunk portion (3) is also formed to have relations of R1≧R2≧R3, when a peak (5) or the joint portion between the two flat faces has a diameter of R1, when the crest of the ridges has a roundness of R2, and when a valley (7) has a roundness of R3, in that the valley (7) is formed to correspond partially to the peak (5), and in that the thickness becomes continuously larger from the tapered portion (2) to the trunk portion (3).

    • In the present invention, at each of the plurality of points in a wide area, the phase of voltage at a power supply outlet is detected. Data including the phase information and time information are sent to a data server. With one end of the system used as a phase angle reference, the data server observes phase differences at the other end and at the center of the system. The data server then extracts an inter-system fluctuation component from an obtained fluctuation, and constructs an expanded combined vibration model for data sets obtained through first-order and second-order differentiations of the component. The expanded combined vibration model is obtained by expanding a combined vibration model to include a known model of a PSS provided for a generator of interest. Time-series data regarding the state variables of the PSS at the time of construction of the expanded combined vibration model are obtained, and PSS parameters are determined directly therefrom by use of the expanded combined vibration model, whereby stabilization of the dominant modes is achieved.
    • 在本发明中,在广域的多个点的各个点处,检测电源插座的电压的相位。 包括相位信息和时间信息的数据被发送到数据服务器。 将系统的一端用作相位角参考,数据服务器观察系统另一端和中心处的相位差。 然后,数据服务器从获得的波动中提取系统间波动分量,并构建通过该分量的一阶和二阶微分获得的数据集的扩展的组合振动模型。 扩展的组合振动模型通过扩展组合振动模型来获得,以包括为感兴趣的发生器提供的PSS的已知模型。 获得关于在扩展的组合振动模型构建时的PSS的状态变量的时间序列数据,并且通过使用扩展的组合振动模型直接确定PSS参数,从而实现主要模式的稳定。
