Patent number: 4818935Abstract: Method and apparatus for non-destructive inspection of flaws in metal materials include exciting coils centered on a longitudinal axis of a cylindrical or columnar metallic material to be examined being arranged to surround the examinee material. A multiphase alternating current of such a relatively low frequency as to cause the exciting coils to generate a rotating magnetic field which rotates about the longitudinal axis of the examinee material is superimposed with a high frequency alternating current having an inspection frequency selected on the basis of the necessary sensitivity for detection of surface flaws of the examinee material. The composite multiphase current is applied to the exciting coils so that an electromagnetic effect induced in the surface of the examinee material by the high frequency alternating current is rotated for shifting circumferentially about the examinee material along with the rotating magnetic field.Type: GrantFiled: February 5, 1987Date of Patent: April 4, 1989Assignees: Nippon Steel Corporation, Eddio CorporationInventors: Michiaki Takahashi, Mitsuo Yoshida, Kazuyoshi Miyazawa, Sigeyuki Nitta, Junichi Fujisawa, Nobuji Obara, Shoji Hayashibe, Yoshikazu Sawada

Patent number: 4397719Abstract: Nitrates, such as alkali metal nitrates and ammonium nitrate, are electrolytically reduced to the corresponding nitrites by a process wherein an aqueous solution containing a nitrate is supplied into a cathode chamber of an electrolytic cell including cathode and anode chambers separated by a cation exchange membrane and an electric current is applied to the electrolytic cell, while maintaining the pH of the aqueous solution at a value of at least about 4. This process can be advantageously applied not only to the manufacture of nitrites but, also, to the treatment of waste nitrates. In the treatment of waste ammonium nitrate, the ammonium nitrite so formed is conveniently further treated by subjecting the electrolytically reduced catholyte to thermal decomposition outside the electrolytic cell, and removing the so formed nitrogen and water from the reaction system.Type: GrantFiled: September 14, 1981Date of Patent: August 9, 1983Assignees: Asahi Kasei Kogyo Kabushiki Kaisha, Doryokuro Kakunenryo Kaihatsu JigyodanInventor: Mitsuo Yoshida

Method for the electrolysis of an aqueous solution of an alkali metal chloride and an anode therefor
Patent number: 4354905Abstract: The use of a perforated plate anode in combination with a cation exchange membrane has been found to be extremely effective for rendering the current distribution in the cation exchange membrane uniform in practice of the ion exchange membrane process for the electrolysis of an aqueous solution of an alkali metal chloride. The uniform current distribution in the cation exchange membrane is, in turn, effective for preventing elevation of the electrolytic voltage and prolonging the life of the cation exchange membrane. Further, when the coating of the perforated plate anode on its front surface and the inner wall surfaces of the openings has a thickness larger than that of the coating on the back surface, the perforated plate anode has high durability and exhibits low electrolytic voltage for a long time as compared with the perforated plate anode having, on each surface, a uniform-thick coating.Type: GrantFiled: April 13, 1981Date of Patent: October 19, 1982Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Mitsuo Yoshida, Hiroyoshi Matsuoka -

The electrolysis voltage can be considerably reduced at a high current efficiency to provide a great economical advantage.Type: GrantFiled: February 15, 1980Date of Patent: April 6, 1982Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Mitsuo Yoshida, Yoshinori Masuda, Akio Kashiwada
