Inventor: YAMAZAKI SHUNPEI
IPC: C23C16/48
Filed: 1986-11-25
Abstract: PURPOSE:To increase light emitting intensity and to prevent a drop in the life by narrowing the inner diameter of a light emitting part, and forming a buffer space between the light emitting part and an electrode. CONSTITUTION:Buffer spaces 23, 23' are formed between electrodes 3, 3' and a light emitting part 2 in a quartz bulb 21. The mercury vapor pressure inside the bulb 21 is made constant by utilizing the buffer spaces 23, 23'. Thereby, even if the temperature inside the bulb 21 is raised to 75-400 deg.C, light having a wavelength of 185nm is efficiently emitted. By throttles 26 formed between buffer spaces 23, 23' and spaces 22, 22' for electrodes 3, 3', ions having high energy in the light emitting part decrease the energy. Thereby, the light intensity of ultraviolet rays having a wavelength of 185 nm is increased and a drop in the life is prevented.

Title: Method for producing fullerenes
Inventor: MATSUMOTO MASABUMI
IPC: C01B31/02
Filed: 1991-10-29
Abstract: PURPOSE:To efficiently use carbon material in producing fullerenes. CONSTITUTION:Soot contg. fullerenes is formed in a fullerene producing device 50, introduced into a heating vessel 68 of a fullerene separator 66 and heated by a heater 70.

Since the soot separated from the fullerenes is recycled in this way as the raw material, the cost of raw material is reduced. High-purity fullerenes are obtained because the fullerenes are heated, sublimated and removed from the formed soot, and the production process is also simplified.
