Title: Manufacture of lanthanum-boride thermionic emission electrode
Inventor: KANETANI KOUICHI
IPC: H01J1/20
Filed: 1981-02-02
Abstract: PURPOSE:To obtain a lanthanum-boride thermionic emission electrode with increased life by  depositing lanthanum boride over a high-melting-point metal electrode material by ion beam  sputtering vapor deposition, with a deposition layer of a specified metal or metal oxide interposed between the electrode material and the lanthanum boride deposition layer. CONSTITUTION:At least one compound chosen from among carbon, Re, Ta, Al2O3, SiO2 and  B2O3 is deposited on the surface of a high-melting-point metal electrode material such as W,  Mo or Ta by ion beam sputtering vapor deposition, thereby forming a lower layer. A lanthanum boride layer is formed on the surface of the above lower layer by subjecting a lanthanum  boride having a high luminance and a high decomposing ability, such as LaB6, to ion beam  sputtering vapor deposition. In addition, as occasion demands, an outer layer is formed on the  above lanthanum boride layer through the vapor deposition of at least one compound chosen  from among the metals and the metal oxides used for the above lower layer. Owing to the  double layer formation, any reaction which might be caused between the lanthanum boride  and the electrode material during the use of the electrode can be prevented, and the stability  of the electrode is enhanced. Besides, formation of the outer layer can prevent any damage to  the lanthanum boride layer, which might be caused due to collisions between ionized C, H,  H2O, N or the like.

Filed: 1990-01-22
Abstract: PURPOSE:To perform a rapid, accurate and facilitated measurement by arranging a half mirror light branching element with a reflecting film on a light source side and measuring the displacement of the height of an object to be measured by interference fringes. CONSTITUTION:A half mirror 2 with a reflecting surface 3 is provided on a light source side to construct a simple type Michelson interferometer.
