摘要： A pipe joint unit having key members which are struck to bite the surfaces of the pipes is provided with which the pipes can easily and quickly be joined to the body of the pipe joint unit with small force, without skill and regardless of the person who drive the key member. The pipe joint unit according to the present invention includes a body of the pipe joint unit having through holes each of which faces a portion of an inserted pipe in a direction of a tangent line; and key members to be driven into the through holes, wherein each of the key members has a tapered portion which is brought into contact with the surface of the pipe in an initial stage of a driving operation and which bites the surface of the pipe as the driving operation proceeds, and a secured portion to be secured to the bitten portion.

摘要： A drill in which no positional shift on a drilled hole and no irregularities on an internal wall are formed. A torsion angle of a shaving discharge groove of a drill is set in the range of 30 degrees to 50 degrees. In this manner, a positional shift of a through hole to be drilled can be reduced. In addition, shavings of the drill are properly discharged, and thus, drilling is not precluded by the shavings. Therefore, a printed wiring board having excellent electric connectivity and reliability can be obtained.
摘要翻译： 一种钻孔，其中不形成钻孔上的位置偏移并且不形成内壁上的凹凸。 钻头的剃须排放槽的扭转角度设定在30度到50度的范围内。 以这种方式，可以减少待钻孔的位置偏移。 此外，钻头的切屑被适当地排出，因此钻孔不被刨花排除。 因此，可以获得具有优异的电连接性和可靠性的印刷线路板。
