Patent number: 7197117Abstract: A coolant passage is formed inside the rotary shaft while an air passage is formed inside the casing. A mechanical seal is arranged between the coolant passage and the air passage. Leakage cooling water, which has leaked in the form of vapor from the mechanical seal, is relegated radially outwardly along with air by the action of a rotary vane, which is disposed in the air passage, and finally flows out of an air outlet. A coolant sensor may be provided to early detect the leakage water.Type: GrantFiled: July 13, 2005Date of Patent: March 27, 2007Assignee: Rigaku CorporationInventors: Masataka Sakata, Tomohiro Chaki, Masaru Okazaki, Yuji Kusaka, Shiro Umegaki, Atsushi Hamanaka, Masahiro Nonoguchi

Patent number: 6266392Abstract: A soller slit is disclosed, which includes a plurality of metal foils and functions to restrict divergence of X-rays when arranged on an X-ray optical path. The metal foils are prepared by sintering a metal material such that surface thereof have high harmonic surface roughness. Alternatively, the metal foil has oxides formed by oxidation on the surfaces thereof such that the oxides can provide the high harmonic surface roughness. The high harmonic surface roughness of the metal foil restricts total reflection of X-rays at the metal foil. Therefore, it is possible to form high precision parallel X-ray beams by the soller slit to thereby improve resolution in an X-ray measurement.Type: GrantFiled: October 27, 1999Date of Patent: July 24, 2001Assignee: Rigaku CorporationInventors: Go Fujinawa, Shiro Umegaki
