An all-solid-state cell has a fired solid electrolyte body, a first electrode layer integrally formed on one surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte, and a second electrode layer integrally formed on the other surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte. The first and the second electrode layers are formed by mixing and firing the electrode active material and the amorphous solid electrolyte, which satisfy the relation Ty&#x3e;Tz (wherein Ty is a temperature at which the capacity of the electrode active material is lowered by reaction between the electrode active material and the solid electrolyte material, and Tz is a temperature at which the solid electrolyte material is shrunk by firing).

All-solid-state cell

An all-solid-state cell contains a combination of an electrode active material and a solid electrolyte, and has a plate-shaped fired solid electrolyte body of a ceramic containing a solid electrolyte, a first electrode layer (e.g. a positive electrode) integrally formed on one surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte, and a second electrode layer (e.g. a negative electrode) integrally formed on the other surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte. The solid electrolyte materials added to the first electrode layer and the second electrode layer comprise an amorphous polyanion compound.

A first paste for a first electrode layer and a second paste for a second electrode layer are printed on a fired solid electrolyte by screen printing, etc. to form electrode patterns for forming the first electrode layer and the second electrode layer. The first and second pastes can be prepared by dissolving a binder in an organic solvent, adding an appropriate amount of the obtained solution to powders of an electrode active substance material and a solid electrolyte material, and kneading the resultant mixture. The first and second pastes are applied to the fired solid electrolyte to form a cell precursor, the cell precursor is placed in a hot press mold subjected to a thermal treatment while pressing from above by a punch, whereby the first and second electrode layer are formed from the first and second pastes.

The PLCadaptor corresponding to a power line communication apparatus has four PLC bridgesA toD, each of which is correspondingly connected to Ethernet communication connectorsA toD, operation mode setting switchesA toD, display unitsA toD. Each PLC bridgeA toD includes a PLC modem unit, a bridge unit, an Ethernet IF unit, and a communication control unit. The communication control unitobtains data type information on the basis of setting conditions of switchesA toD corresponding to each communication port. Since the time slot required for the communication link corresponding to the communication port of the PLC network can be obtained on the basis of the data type information, the reservation request can be transmitted to the control terminal.
