摘要:
A liquid ejecting device to eject droplets of liquid onto a recording medium is provided. The image ejecting device includes a recording medium conveyer, a liquid ejecting head, a detector unit, an image data storage, a controller, and a cancellation signal output unit to output cancellation signals in an error condition. The controller includes a creating unit to create first dot pattern data and sum segments extracted from the first dot pattern data to create second dot pattern data, a transmission unit, and a cancellation controller unit to stop the creating unit, create second dot pattern data by adding a dot pattern to the segments having been extracted from the first dot pattern data, and transmit the created second dot pattern data to the transmission unit. The controller controls the liquid ejecting head to eject the droplets from the nozzles according to the second dot pattern data.

A fuel cell generation system comprises a cell stack consisting of a plurality of cells, said cell having a fuel electrode, an oxidizer electrode, and an electrolyte layer located between said both electrodes, a fuel cell main body having a plurality of cooling plates for absorbing heat generated in said cell, said plate being located between said cells, and a cooling unit for supplying a coolant through said cooling plate. The system further provides a reference voltage source for supplying a reference voltage and a determining unit for comparing an output voltage of at least one cell located at the upper portion of the cell main body with the reference voltage and determining if an abnormal state occurs in the cooling unit based on the comparing result. The reference voltage is picked up out of a part of the cell stack.
