Abstract: <P>PROBLEM TO BE SOLVED: To provide a power line communication system capable of reducing leakage of electric field from a distribution line by attenuating a different potential component from ground.  <P>SOLUTION: Electric power is tapped from two lines of a high voltage distribution line 3 and is connected to the primary side of a pole transformer 2, and the middle point on the secondary side is grounded by a ground line 10.

The capacitor 7b is set to such capacitance that indicates a high impedance for a commercial frequency (50/60Hz) while showing low impedance for a high frequency. Since only the signal of high frequency is passed to the coupling transformer 7a while a commercial frequency is blocked, the capacitance of a transformer can be reduced. So, the signal of high frequency occurs on the secondary side of the coupling transformer 7a, which is inputted in a modem 6 through a twisted pair cable 8.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a fuel cell, an electronic equipment or a camera wherein the used condition of fuel can be confirmed easily by vision.  <P>SOLUTION: The fuel 40 in which water and bromothymol blue solution (BTB solution) are mixed in colorless and transparent and neutral methanol is housed in a fuel chamber 24. The fuel 40 is decomposed into hydrogen ion, electron, and carbon dioxide (CO<SB>2</SB>) by catalytic reaction at a fuel electrode 21. When the CO<SB>2</SB>discharged on the fuel chamber 24 side is dissolved into the water of the fuel 40, the fuel 40 colored in green (as shown in the upper right hatching) by the BTB solution is acidified and turns yellow (as shown in the upper left hatching). Because generated amount of the CO<SB>2</SB>is increased depending on the consumption of the fuel 40, the dissolved amount of the CO<SB>2</SB>is increased, and the degree of acidity is enhanced, and therefore the color of the fuel 40 is varied corresponding to the used amount of the fuel 40. That is, by confirming the color of the fuel 40 visually other than the liquid level of the fuel 40, the used amount of the fuel 40 can be grasped easily, and the convenience is improved.  <P>COPYRIGHT: (C)2004,JPO
