Patent number: 6869574Abstract: A charged particle generating method in which mode is changeable between an ion generation mode and an electron generation mode. In the ion generation mode, a raw material is supplied to a tip end of a charged particle generating electrode through a raw-material passage formed in the charged particle generating electrode. A first electric field, in which the charged particle generating electrode is positive and the charged particle extract electrode is negative, is generated to emit ions from the raw material at the charged particle generating electrode. In the electron generation mode, supplying the raw material from the raw-material supply section is stopped. A second electric field, in which the charged particle generating electrode is negative and the charged particle extract electrode is positive, is generated to emit electrons from the raw material at the charged particle generating electrode.Type: GrantFiled: March 7, 2002Date of Patent: March 22, 2005Assignee: Vacuum Products CorporationInventors: Hisao Hojoh, Masatoshi Ono, Morinobu Endo, Tetsuo Uchiyama

Patent number: 6008479Abstract: In an infrared radiation source containing hot-pressed molybdenum disilicide reinforced with silicon carbide whiskers as the illuminant thereof, terminal portions of the illuminant having a protective dense silica film of 5 to 20 .mu.m in thickness formed on the surface thereof which portions are to be heated at a temperature of 400 to 800.degree. C. are either set to have a current density of at most 12 A/mm.sup.2 or disposed in dry air having a relative humidity at 25.degree. C. of at most 30% (absolute humidity: 0.00588). As a result, the low-temperature oxidation phenomenon that would otherwise be developed in the terminal portions of the illuminant is suppressed.
