Title: Optical communication system
Inventor: TAKAYAMA KOICHI
IPC: H04L12/42
Filed: 1988-02-08
Abstract: PURPOSE:To specify a fault location quickly by receiving a signal from a reception section so as to detect whether or not communication via an optical fiber is enabled and providing a control section sending a control signal of a signal transmission line medium and controlling an optical switch when the disabled communication is detected. CONSTITUTION:A control section 104 detecting the disabled communication by the optical fiber 101 transmits the optical switch 108 into the communication mode by a switching signal through a signal line 107, sends a positive voltage control signal to a metal cable 102 and brings other optical switch 108 of the other mode into the bypass test mode. Then the control section 104 of the node detecting communication disable sends a prescribed signal (signal having a prescribed pattern) to an optical transmission module 106 to conduct the test as to the reception via the optical reception module 103. When a prescribed signal is received in the communication mode (A) and the bypass test mode (B), it is regarded that a fault exists in other node and when the prescribed signal is not received in the communication mode and bypass test mode, it is regarded to be the presence of a fault in its own node.

Abstract: PURPOSE:To decrease the number of processes, and to form element isolation by etching a polysilicon layer and a flattening resist at the same etching rate and flatly leaving polysilicon in a trench in a substrate surface. CONSTITUTION:Trenches are shaped onto the surface of an N-type semiconductor substrate 11, a polysilicon layer 12 is formed, and a resist 13 for flattening is applied onto the polysilicon layer 12. The resist 13 for flattening is used for burying the indentations of the polysilicon layer 12, but the resist is applied and the indentations of the resist are shaped to the upper sections of the indentations. When both polysilicon and the resist are etched simultaneously so that the etching rates of polysilicon and the resist are equalized, the resist is not left, and the indentations of polysilicon after etching can be scaled down. The polysilicon layers in the trenches are oxidized, and silicon dioxide layers as insulators are formed. Accordingly, the number of processes is decreased, and the state of element isolation can be shaped.
