摘要： PROBLEM TO BE SOLVED: To realize superior high-frequency characteristic by applying a solution containing a metal-containing compound to a dielectric substrate, calcining it to form a high-temperature superconductive film and executing prescribed patterning. SOLUTION: After dissolving each acetylacetonate of yttrium, barium and copper into pyridine and proprionic acid, a solvent is distill-removed to be dissolved into methyl alcohol to generate an applying liquid. The obtained applying liquid is applied to a dielectric substrate, consisting of LaAlO3 by a spin coat method and heat-warmed. Similar operation is given to the rear side surface of the dielectric substrate to form an inactive film consisting of yttrium oxide, barium carbonate and copper oxide is formed on both surfaces of the dielectric substrate. A filter of sharp characteristic consisting of a large- area film, having high-frequency characteristics, is obtained by manufacturing a hair pin filter by giving prescribed patterning to the film formed on both surfaces of the dielectric substrate.

摘要： PURPOSE:To produce hydrogen at an excellent reaction rate, with high heat efficiency and in high yield by improving the process when gaseous hydrogen is thermochemically produced from water by an Mg-S-I cycle method. CONSTITUTION:A gaseous mixture of SO2 and O2 is blown into an aq. slurry at 0-120 deg.C wherein MgO and I2 are suspended in water to form a slurry consisting of an aq. soln. of MgSO4 and MgI2. The slurry is separated by filtration, centrifugation, etc., into an MgSO4 crystal and a concd. soln, of MgI2. The concd. soln. of MgI2 is heated, concentrated and evaporated to dryness. The residue is further heated at 400 deg.C to generate HI and the residue of MgO is returned to the first stage. The MgSO4 obtained by the preceding stage is brought into contact with an aq. soln. and the soln. is heated at 900-1,200 deg.C to generate SO2 and O2 and the residue of MgO is returned to the first stage. Then the HI is brought into contact with an aq. soln. and the soln. is thermochemically decomposed by electrical energy into a gaseous mixture of H2 and I2. The I2 is condensed with use of a separation membrane or by cooling and high-purity gaseous H2 is separated from the I2 and recovered in high yield.

摘要： PURPOSE:To make it possible to efficiently perform the charging and discharging processes by using a water solution containing hydrogen chloride, ferrochloride and ferrichloride while regulating its hydrogen chloride concentration within a specific range. CONSTITUTION:A charging process in which ferrochloride in a water solution containing hydrogen chloride, ferrochloride and ferrichloride is partly oxidized into ferrichloride at an anode electrode to generate hydrogen at a cathode electrode and a discharging process in which generated hydrogen is oxidized at the anode electrode while reducing a water solution containing generated ferrichloride at the cathode electrode to generate ferrochloride and hydrogen chloride constitute the captioned method. Thereby, the respective water solutions containing chlorinated iron have hydrogen chloride concentration, desirably 2-7mol/kg-H2O and the total iron concentration of the primary iron and the secondary iron, desirably 1-4mol/kg-H2O, while a mol ratio of the primary iron to the secondary iron is desirably in the range of 1/3-3/1.
