Title: Fuel cell
Inventor: SAITO HAJIME
IPC: H01M8/02
Filed: 1992-07-17
Abstract: PURPOSE:To reduce the corrosion at the outer periphery end sections of separators and the inner end sections of manifolds due to the leakage of an electrolyte and extend the cell life by pinching a dry seal between the separators to surround an electrolyte plate. CONSTITUTION:A fuel cell is constituted of multiple cells 4 each consisting of two parallel electrodes, an anode 2 and a cathode 3, and a flat electrolyte plate (tile) 1 pinched between the electrodes and separators 10 pinched between the cells 4. A dry seal 20 such as a ceramic packing is pinched between the surfaces of adjacent separators 10 to surround the tile 1. Even if an electrolyte is leaked from the tile 1, the further leakage is blocked by the dry seal 20, and the corrosion at the outer periphery end sections of the separators 10 can be reduced.

Title: Manufacture of thin film type optical element
Inventor: MIYAWAKI MAMORU
IPC: G02F1/125
Filed: 1985-08-29
Abstract: PURPOSE:To substantially increase the threshold value of an optical damage and to improve the coupling efficiency in the input and output stage of guided light by injecting protons to the surface of a lithium niobate crystal substrate or lithium tantalate crystal substrate. CONSTITUTION:The y plane or x plane of the lithium niobate crystal substrate 1 is first polished flat, then the surface is subjected to ordinary ultrasonic cleaning by acetone followed by pure water. The surface is dried by blowing gaseous nitrogen to form a thermally diffused Ti layer. A proton exchange layer 13 is formed in the diffused layer 11 and a thin Au film is deposited by evaporation only to the region where surface acoustic waves and the guide light act on each other. On the other hand, the thin Au film is deposited by evaporation on the rear side of the substrate as well and while a voltage 12 is impressed thereto, the thin film is subjected to an annealing treatment. As a result, an optical waveguide layer 31 which is shallower in the depth of diffusion than in the optical coupling section and has the high density of the protons on the substrate surface is formed. The refractive index near the surface is decreased when the surface of the waveguide 31 is subjected to the laser annealing treatment by a laser 15. A low refractive index layer 16 is thus formed and finally a comb-shaped electrode 14 is formed.
