Title: Electrochromic display element
Inventor: IWATA TOMOO
IPC: G02F1/15
Filed: 1986-12-17
Abstract: PURPOSE:To improve responsiveness and reliability by disposing a porous material formed by bonding the particles of silicon carbide with the particles of polytetrafluoroethylene (PTFE) between a display electrode over counter electrode and impregnating a liquid electrolyte into said porous material. CONSTITUTION:The porous material formed by bonding the particles 10 of the silicon carbide by the particles 11 of the PTFE is disposed between the display electrode and counter electrode and the liquid electrolyte 6B is impregnated into the porous material. More specifically, the material formed by bonding the particles 10 of the silicon carbide by the particles 11 of the PTFE is porous and, therefore, if the liquid electrolyte 6b is absorbed and held therein, material transfer (ion transfer) takes place via the porous parts and since the ions have electric charge, the material transfer corresponds to electric current. Since the liquid electrolyte 6B is held in the porous material, the leakage of the liquid electrolyte 6B to the outside of the display element is eventually obviated. The electrochromic (EC) display element provided with both the high speed responsiveness and high reliability is thus obtd.

Abstract: PURPOSE: To improve a using efficiency of a network by arranging in common the data Q showing the communication quality as a part of a packet header or a trailer of every hierarchy and referring to the data Q to process the packets in every hierarchy. CONSTITUTION: When the data are transmitted, the data string received from a higher hierarchy is divided in a TCP packet 11 and the communication quality request value Q given from the higher hierarchy is buried in a part 13 of an added TCP header 12. Then the part 13 is transformed into an IP packet 14 and the value Q common to the part 13 is buried into a part 16 of an added IP header 15. The value Q is transformed into an ATM cell 17. At the same time, the value Q common to the part 16 is buried into a part 19 of an ATM header 18. Then the packet processing is properly carried out in every hierarchy based on the value Q, and the cell and the packet are disused. Thus it is possible to prevent the useless packet transmission by the preferential processing, to evade the congestion, to effectively use a transmission line, and to transmit the data in real time and with high quality.
