Abstract: In a communication network having a plurality of stations interconnected through a double ring transmission line, a station which detects a failure in the ring transmission line sends out a failure notice data, and a station which has received the failure notice data stops the send-out of its own data and relays the received data. A station which cannot receive the failure notice data loops back and transmission line to form a closed ring transmission line which bypasses a failure location.

Abstract: A leadframe comprising a thin-walled portion that is formed in a dam bar portion or a portion that extends from the dam bar portion to a pair of inner leads which are adjacent thereto. By cutting the dam bar portion along the thin-walled portion, the stress that is imposed on a cutting punch is reduced. Thus, it is possible to extend the lifetime of the cutting punch and also to minimize the shear droop formed on the cut surface. The leadframe further has a thick-walled portion formed at the position where the thin-wall portion is formed. The thick-walled portion serves to support the thin-walled portion when the dam bar portion is cut off, thus preventing the dam bar portion from tilting. Accordingly, the dam bar cutting operation can be conducted stably without undesired movement of the dam bar portion, and the stress that is imposed on the leadframe can be controlled so as to be well balanced.

Abstract translation: 一种引线框架，包括形成在阻挡杆部分中的薄壁部分或从阻挡杆部分延伸到与其相邻的一对内部引线的部分。 通过沿着薄壁部分切割堤坝部分，施加在切割冲头上的应力减小。 因此，可以延长切割冲头的寿命并且还可以最小化在切割表面上形成的剪切下垂。 引线框还具有形成在形成有薄壁部的位置的厚壁部。 当堤坝部分被切断时，厚壁部分用于支撑薄壁部分，从而防止堤坝部分倾斜。 因此，可以稳定地进行坝条切割操作，而不会妨碍挡块部分的移动，并且可以控制施加在引线框架上的应力以使其平衡良好。
