Filed: 1981-05-27
Abstract: PURPOSE: To obtain infrared laser beams with stable wave length by constituting light source for infrared irradiation from infrared laser of a semiconductor such as PbSnTe or PbSnSe.  
     CONSTITUTION: Infrared laser source 4 is focused to the UF 6  gas injected from an injection nozzle 2 from semiconductor infrared laser 3 to irradiate the same and only U 235  is excited to be desociated by ultraviolet rays to obtain 235 uranium-235 pentafluoride.

Abstract: PURPOSE:To suppress a short-circuit toward a positive electrode caused by projected conductive core bodies, by using a negative electrode, where the conductive core bodies on both end edges are buried in an active material paste layer, while the active material paste layer is formed only on one side of the conductive core bodies in the central part. CONSTITUTION:In a negative electrode having an active material paste layer 1 consisting of a hydrogen absorbing alloy and a binder, the conductive core bodies of both end edges, which are in parallel to the direction of winding of the negative electrode 2, are buried in an active material layer 1b while the negative electrode central part, which exists in parallel to the direction of winding, uses the negative electrode, where the active material paste layer 1a is formed only on one side of the conductive core, while being provided with a spiral electrode body built up in a wound winding form through a positive electrode and a separator. Since both end conductive core bodies, which are in parallel to the winding direction of the negative electrode, are buried in the active material paste layer in this way, the problem such as the conductive core bodies on both end edges may project and penetrate the separator to cause a short-circuit toward the positive electrode, may not be generated.
