透明な石英ガラス製のバルブ内に対向配置し、それぞれの先端にコイル部が巻回された一対の電極とこれらの電極に巻かれたコイル部の先端を溶融して略半球形状に一体化し、この半球形状の先端に突起部を形成して高圧放電灯を構成した。
A pair of electrodes are disposed face to face in a transparent bulb of quartz glass, a coil part is wound around the tip of each electrode, the electrode and the tip of the coil part wound around the electrode are fused and integrated in an almost hemispherical shape, and the protrusion is formed at this hemispherical tip to structure this high pressure discharge lamp. - 特許庁
