Latest Patents

Sakuma holds a patent for a "Method of making a cold cathode gas laser discharge tube." This invention utilizes press-molded flanged glass envelope members, each featuring a central hollow cylindrical portion. This design enables the fabrication of high-output cold cathode gas laser tubes that are shorter in axial length and significantly reduce production costs. The cylindrical portion of one envelope member surrounds one end region of the capillary tube, preventing discharge concentration on the adjacent end region of the cylindrical cold cathode. The other envelope member supports the capillary tube at about the middle of its axial length, eliminating the need for a 'flaring operation' that typically requires highly skilled labor.
