Title: Humidity detecting circuit
Inventor: FUJITO KATSUYUKI
IPC: G01N27/22
Filed: 1978-05-02
Abstract: PURPOSE: To increase accuracy and detect relative humidity accurately even when temperature fluctuates with a simple circuit constitution by making use of the characteristics of a humidity detecting element whose electrostatic capacity changes with humidity.  
     CONSTITUTION: A first pulse generating circuit 1 causes a humidity detecting element 2 to be charged and discharged by a charging-discharging circuit 3 and the voltage across the humidity detecting element 2 becomes one input to a voltage comparator 5. The output of a voltage generting circuit 4 becomes another input to the voltage comparator 5 as a slice level voltage. A second pulse generating circuit 6 causes a capacitor 7 to be charged and discharged by a charging-discharging circuit 8, but the slice level voltage of the voltage generating circuit 9 changes with temperature and therefore the output of the voltage comparator 10 changes in pulse width with temperature. Next, the difference between the output pulses of the pulse generating circuits 1, 6 is outputted by an arithmetic circuit 11. If the pulse width proportional to relative humidity is obtained in this way,the humidity may be digitally displayed.

Title: Electrolytic ozone generating element
Inventor: MATSUOKA HIROMASA
IPC: C25B9/19
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To suppress the corrosion reaction at an anode and to improve the life thereof by disposing a thin film of a solid polymer electrolyte having the acidity weaker than the acidity of a solid polymer electrolyte film between the anode and the electrolyte film. SOLUTION: The film 20 of the solid polymer electrolyte having the weak acidity is formed as the extremely thin layer on the surface layer of the solid polymer electrolyte film 1 and is interposed between an anode catalyst layer 4 and the solid polymer electrolyte film 1 to prevent the contact of both. More preferably the solid polymer electrolyte film 1 is a sulfonic acid type and the film 20 is carboxylic acid type. When the generation of ozone is ceased by stopping the impression of voltage, the potential of the anode falls and the lead tends to elute from the anode catalyst layer 4 containing lead oxide. The acidity of the film 20 in contact with the lead dioxide is, however, weak and there is no possibility that the anode potential enters a region of Pb2+ if the atmosphere is the air atmosphere.  Namely, the anode is stably maintained as the lead dioxide even if voltage is not impressed at the time of stoppage.
