Abstract: There is provided a cylindrical fixing flange structure for a high-pressure gas container filled with high-pressure gas. The cylindrical fixing flange structure includes a high-pressure side primary seal zone provided with a metal touch seal and an atmosphere-side secondary seal zone provided with an elastomer seal. The high-pressure side primary seal zone and the atmosphere-side secondary seal zone are arranged adjacently to each other in the cylinder direction of the high-pressure gas container. The cylindrical fixing flange structure is a sealing structure which has a high degree of freedom of design and is suitable for a high-pressure hydrogen gas container for a fuel cell, in which the durability and reliability against pressurization/depressurization stress, which poses a problem with the sealing structure using elastomer seal only, are ensured, the gastightness is high, and the volume, especially the transverse width, of sealing structure is restrained.

Abstract: By reason of a manufacture cost cut, the following method to produce plural organic electroluminescent device from a large-scale substrate was invented. A manufacturing method of organic electroluminescent device comprised of a substrate, first electrode on the substrate, partition wall between the first electrodes, organic luminous media layer including organic luminous layer on the first electrode and second layer which faces the first electrode, wherein the organic luminous media layer is sandwiched between the first and the second electrode, the method comprising: preparing ink which material for at least one organic luminous media layer is dissolved in solvent, forming organic luminous media layer by printing the ink on every divided plural domains of the substrate.
