A production line for manufacturing automobiles, for example, has a plurality of movable carriages for carrying workpieces such as automotive bodies and a plurality of work stations for processing the automotive bodies such as by installing parts thereon or machining them. A controller which controls the work stations to process the automotive bodies has a memory having a plurality of storage areas for storing carriage identification data from the carriages that have arrived at the work stations and automotive body type data regarding the automotive bodies on the carriages, and also for storing carriage identification data transmitted from next carriages to arrive at the work stations and automotive body type data about the automotive bodies carried on the next carriages. When a carriage arrives at a work station, the carriage identification data about the carriage and the next carriage are transmitted from the carriage to the work station, and the controller transmits the automotive type data about the automotive bodies on the carriage and the next carriage to the work station. The automotive body in the work station can be processed based on the transmitted automotive body type data about the automotive body on the carriage and then the work station can be prepared based on the transmitted automotive body type data about the automotive body on the next carriage for the processing of the next automotive body which is to arrive next at the work station.

The moving path for lithium-ions and at the same time the moving path for electrons are secured at a charge/discharge time.
Abstract:
A lithium ion battery capable of maintaining for a long time fire resistance of a nonaqueous electrolytic solution at a time of battery abnormality to secure safety is provided. In the lithium ion battery, two kinds of organic solvent, EC and DEC, are used for mixed organic solvent which forms the nonaqueous electrolytic solution, and liquid flame retardant formed by phosphazene A having a boiling point closely to that of EC and phosphazene B having a boiling point closely to that of DEC is added to the electrolytic solution. At battery abnormality, when the battery temperature goes up due to internal short circuit of positive and negative electrodes caused by melting of separators to decompose each of EC and DEC, the phosphazene A and B, each having the boiling point closely to that of EC and DEC, decompose timely to function, thereby fire resistance of the electrolytic solution can be maintained for a long time to secure safety of the battery at the time of battery abnormality.
