Title: Redundant constitution system for digital signal device
Inventor: KOBAYASHI HIDEO
IPC: H04Q1/30
Filed: 1984-01-27
Abstract: PURPOSE:To attain the economical constitution of a circuit by transmitting all digital signals with nondefective one of both signals devices which transmits the digital signals to a highway after allocating those signals to odd and even time slots in case one of both signal devices has a fault. CONSTITUTION:Signal transmission parts 10A and 10B of digital signal devices 1A and 1B deliver 12A and 12B plural types of signals An and Bn (An=Bn) in a synchronous state. A processor drives switch clock transmission parts 11A and 11B via signal lines 16A and 16B to produce 13A and 13B even time slots at either one of parts 11A and 11B and odd time slots at the other part. The signals An (even) and Bn (odd) are sent alternately to a highway 3 via highway gate signal lines 14A and 14B and supplied to digital channel networks 2A and 2B respectively. If the device 1B, for example, has a fault, this faulty device 1B is cut off from a system with the line 15B set at an H level. Then the signals given from the part 10A are all sent to the highway 3. Thus a redundant circuit can be formed economically.

IPC: H04J3/22
Filed: 1989-01-20
Abstract: PURPOSE:To set and vary the bearer speed efficiently by deciding the bearer speed from the clock from a terminal device and automatically setting the bearer speed of a main circuit. CONSTITUTION:A clock extracting circuit 11 extracts a clock from the data from a terminal device. The extracted clock is inputted to band-pass filters 21-24 of center frequencies f1-f4. Voltages appear at output terminals of band- pass filters 21-24 whose center frequencies match the clock frequency among the band-pass filters 21-24, but no voltage is developed at output terminals of other band-pass filters. The voltages from the band-pass filters 21-24 are inputted to comparator 26-29, which decide whether the voltages are higher than a reference voltage or not, decide that the center frequencies of the band- pass filters exceeding the reference voltages are the bearer speed of the data sent from the terminal device, and inputs the result to a switching control circuit 41. The switching control circuit 41 varies automatically the setting of the bearer speed of the main circuit 31 according to the determined bearer speed.

Filed: 1979-02-06
Abstract: PURPOSE: To achieve an improved durability with a simple structure, by disposing a partition board, having no ionic conductivity and having water rejecting property, on the side face of each plate group.  
     CONSTITUTION: Disposed on each element, formed of a positive plate and one or more separators 8 and negative plates 7 which are superposed on the positive plate 6 respectively, is a partition board 9, consisting of polypropylene, ethylene tetrafluoride polymer etc., which is sulfuric-acid-proof and can not be passed through by electrolyte and has an excellent water rejecting property and an area somewhat larger than that of the plate. The electrolyte 11 is caused to be a gel by being mixed with silicic anhydride and dilute sulfuric acid, and a non-return valve is provided at the upper portion of the battery jar 5. Thus, the electrolyte is a gel and does not flow so that the electrolyte in the adjacent cells can not contact with each other, and even if a liquid capable of flowing is produced by syneresis or condensation of steam etc., it is prevented from flowing out from the cells by the water rejecting property of the partition board and the water absorbing property of the separator 8 consisting of porous rubber etc. A lead storage battery with improved durability is thus obtained.
