Filed: 1990-02-01
Abstract: PURPOSE:To prevent corrosion of an air electrode and a gas separating plate by making the size of the air electrode equal to or smaller than that of a fuel electrode and an area within which fuel is supplied. CONSTITUTION:Since an air electrode 21 is limited to the size of a fuel electrode 3 and an area within which fuel or H<+> is supplied, a load current also flows and a normal battery reaction takes place and the potential of the air electrode 21 is kept low. A spacer portion 7 and the portion of a gas separating plate 6 in contact with the spacer portion 7 are separated from an electrolyte and because of the absence of electrode catalysts the spacer portion 7 and the gas separating plate 6 are electrochemically independent of each other and will not be exposed to high potential.

Title: Ring communication system
Inventor: RICHIYAADO JII BAARU
IPC: H04L7/04
Filed: 1984-02-13
Abstract: A ring communications network has a plurality of terminals coupled together to provide a unidirectional communications ring, each terminal being arranged to receive a first digital signal at a data rate associated with the next upstream terminal in the ring and to transmit a second digital signal at a transmit data rate which may be different from the data rate of the received signal. Each signal comprises data packets interleaved with synchronization packets of elastic length to achieve synchronization around the ring. Thus, each terminal has a synchronizing network (12) containing an electric clock generator (32) having a plurality of outputs each shifted in time by a different multiple of 1/8 times the period of a fixed transmit clock signal generated internally by a transmit clock generator (26). In effect, synchronization is achieved by a shallow discretely adjusted delay (FIFO) buffer and sample point readjustment network. The buffer is read at the fixed transmit data rate and loaded at that same rate until the period of elasticity is detected. Then the sample point is reselected to fall in the middle of a transmit bit window effectively changing the FIFO buffer depth.
