Title: Uninterruptible ring network, uninterruptible transmission system, node device for uninterruptible ring network and method for uninterruptible transmitting at the time of generating fault in ring network
Inventor: SHIMIZU YOSHIHIRO
IPC: H04L12/437
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To eliminate interruption of data at the time of a fault by sending a switch request in a direction reverse to the generation path of the fault when the fault is generated at a transmission line and hourly phase-adjusting a signal before the generation of the fault sent from an add station to be a signal after the generation of the fault to output. SOLUTION: When a node station 10-C detects generation of the fault at the transmission line between with a node station 10-B, the switch request is sent in the direction of a node station 10-D by a switch byte, and a D station receiving this transfers the switch request to a node station 10-A when its own station is a through station. At the time of judging its own station to be an add station, an A station bridge-processes the switch node, inserts a path signal before the generation of the fault read from a memory into a transmission line in a direction reverse to the fault generating transmission line and information showing a bridge state to a switch byte by a space channel to output.  A C-station adjusts the phases of the path signal sent from the A-station and the path signal of an active channel and outputs the path signal of a stand-by channel from the A station received after the generation of the fault to a low-speed transmission line.

Title: Schottky barrier diode
Inventor: KITAMURA SHOJI
IPC: H01L29/872
Filed: 1989-12-20
Abstract: PURPOSE:To obtain a GaAs Schottky barrier diode (GaAs SBD) with improved inverse withstand voltage characteristic by enhancing a field plate. CONSTITUTION:An n-type GaAs layer 2 is laminated on one main surface of an n<+> type GaAs substrate 1, a field plate 3 is an insulation layer consisting of a fluoride, it is selectively laminated onto the n-type GaAs layer 2, and a window for Schottky electrode 4 is provided. The Schottky electrode 4 is provided at a window of the field plate 3 and is connected to the n-type GaAs layer 2 and then an ohmic electrode 5 is formed on other main surface on the n<+> type GaAs substrate 1. There are only a small number of end-connecting branches at the interface between GaAs and the fluoride and the interface level density is low so that a depletion layer 6 when a specified bias is applied to SBD expands well along the field plate 3 of the fluoride, thus reducing breakdown due to the interface between GaAs and the fluoride. Therefore, it is possible to obtain an inverse withstand characteristic which is equivalent to the original insulation withstand voltage of the n-type GaAs layer 2 and GaAs SBD with an improved inverse withstand voltage characteristic.
