IPC: H01M8/04
Filed: 1985-11-15
Abstract: PURPOSE:To stop a plant before serious failure will rise by detecting the initial abnormal phenomena of fuel cell from an exhaust gas line with a high sensitive fluorine ion sensor. CONSTITUTION:A fluorine ion sensor 1 for measuring fluorine ion concentration dissolved in condensed water normally uses a fluorine ion electrode and its detecting sensitivity range is 0.02-19,000ppm. Fluorine resin such as polytetrafluoroethylene is used in a fuel cell electrode for binding powder material and giving water repellency. The fluorine resin is decomposed a low molecule fluorine compound such as hydrogen fluoride gas at high temperature caused by failure and the hydrogen fluoride gas is dissolved in water to to form hydro-fluoric acid. When the exhaust gas from a cell is cooled, vapor produced in the cell condenses, and most of hydrogen fluoride gas is captured in water because it is soluble in water. Since fluorine ion concentration in water is measured with a fluorine electrode having a detecting sinsitivity of 0.02ppm, a minor failure can be detected.

Title: Image coder and image decoder
Inventor: MATSUO MASATOSHI
IPC: H04N19/503
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To transmit an image with high quality while saving an output data quantity by coding and outputting an image signal that is divided into a plurality of frequency bands from the lowest frequency band and counting the outputted data quantity so as to reflect the result for coding of a succeeding frequency band thereby controlling the data quantity in matching with a transmission rate of a communication channel. SOLUTION: A coding section 102a applies coding sequentially to image data lit that are divided into frequency bands at a band division section 101 from the lowest frequency band and provides an output of resulting data trough a buffer 106. An output data quantity control section 105a changes a quantization value of the coding section 102a based on a count of output data 119 from the buffer 106 by an output data count section 104 so that a quantization error is decreased when a transmission rate of the communication channel has a margin and so that the output data quantity is decreased when the transmission rate has no room.  Thus, the data quantity to be outputted for each frequency band is controlled in details, then a most efficient data output is conducted in matching with the transmission rate of the communication channel and an image with excellent quality is transmitted while reducing the output data quantity.
