Publication number: 20160327498Abstract: A detector is the one which detects reflected electrons or secondary electrons emitted from a sample as a result of irradiation with an electron beam by an electron beam irradiation unit, and its one end is set into a non-contact state where it is separated from and faces the sample and the other end is supported on and fixed to a drive mechanism, and the drive mechanism freely moves the detector random positions three-dimensionally with respect to the sample. According to this configuration, it is possible to detect reflected electrons and secondary electrons scattered in random directions appropriately, and accurate evaluation of a crystal grain diameter in which no crystal grain boundary is overlooked and acquisition of an isotropic surface shape image are achieved.Type: ApplicationFiled: July 19, 2016Publication date: November 10, 2016Applicant: FUJITSU LIMITEDInventors: Hideshi Yamaguchi, Takeshi Soeda

Patent number: 5425822Abstract: A hard facing chromium-base alloy consisting essentially of 30.0 to 48.0% by weight of nickel. 1.5 to 15.0% by weight of tungsten and/or 1.0 to 6.5% by weight of molybdenum, the balance being more than 40.0% by weight of chromium, and the maximum sum of tungsten and molybdenum being 15.0% by weight. The alloy may also contain one or more of iron, cobalt, carbon, boron, aluminum, silicon, niobium and titanium. When the alloy is used in powder form as a material for hard facing by welding, the alloy may further contain 0.01 to 0.12% by weight of aluminum, yttrium, misch metal, titanium, zirconium and hafnium. 0.01 to 0.1% by weight of oxygen may also be added to the alloy. The alloy has a high degree of toughness wear resistance and corrosion resistance. The alloy can be used as a hard facing material to be applied to various objects, such as automobile engine valves.Type: GrantFiled: November 30, 1993Date of Patent: June 20, 1995Assignee: Fukuda Metal Foil & Powder Co., Ltd.Inventors: Kensuke Hidaka, Kanichi Tanaka, Yoshio Kohira, Hideshi Yamaguchi, Yoshinao Suzuki, Masahiro Nakagawa, Yoshio Fuwa, Kazuhiko Mori, Yoshihiko Ito, Atsushi Taguchi
