    • A drill has a pair of cutting edges (4) which are arranged at positions that are substantially uniformly circumferentially spaced about its rotation axis. Each of the cutting edges (4) has a first linear cutting region (4a) and a second linear cutting region (4b) which are aligned with each other on the same straight line, and a curved cutting region (4c) which is located between the first and second linear cutting regions (4a, 4b). The curved cutting region (4c) has a third linear cutting region (4e, 4f) which extends in a direction intersecting with the second linear cutting region (4b) at a prescribed angle. With this structure, it is possible to prevent chip loading etc. which may be caused during perforation drilling operations. In a throw-away tipped drill, a notch (118a) is formed in a received portion of an insert (110) which is mounted on a shank (130). A holding portion (131a, 131b, 133a, 133b) of the shank (130) corresponding to the notch (118a) is provided with a through screw hole (138). A male screw (139) is inserted in the through screw hole (138), and a spherical pressing member (140) is interposed between the forward end of the male screw (139) and the surface of the notch (118a) of the insert (110). With this structure, it is possible to prevent separation of the insert (110) from the shank (130).
    • 钻头具有一对切削刃(4),它们被布置在基本上围绕其旋转轴线周向间隔开的位置处。 每个切削刃(4)具有在相同直线上彼此对准的第一线性切割区域(4a)和第二线性切割区域(4b),以及位于 第一和第二线性切割区域(4a,4b)。 弯曲切割区域(4c)具有在与第二线性切割区域(4b)交叉的方向上以规定角度延伸的第三线性切割区域(4e,4f)。 利用这种结构,可以防止在穿孔钻孔操作期间可能引起的切屑加载等。 在扔掉的钻头中,凹口(118a)形成在安装在柄(130)上的插入件(110)的接收部分中。 与凹口(118a)相对应的柄部(130)的保持部(131a,131b,133a,133b)设有通孔(138)。 外螺纹(139)插入通孔(138)中,并且在外螺纹(139)的前端和插入件的凹口(118a)的表面之间插入有球形按压构件(140) (110)。 利用这种结构,可以防止刀片(110)与柄(130)分离。

    • An abnormal traffic detection apparatus for detecting an abnormal traffic toward a communication apparatus by using information on traffics passing through a switch, comprising destination IP address counting units (C1 to C4) configured to store amount information on amount of traffics as an amount information table corresponding to each communication apparatus, a traffic separating unit (21) for registering amount information on a new destination IP address in the amount information table corresponding to the destination IP address, each time a traffics having the new destination IP address passes through the switch, and storing the amount information in the amount information table corresponding to each communication apparatus, and abnormal traffic judging units (J1 to J4) for detecting an abnormality of the traffic amount flowing through the switch on the basis of the amount information stored in the amount information table.
