Patent number: 4973393Abstract: An aluminum film is formed on the surface of a substrate magnesium or magnesium alloy, and the resulting product is heated in a non-oxidizing or reducing gas having a high hydrostatic pressure at a temperature ranging from the eutectic point of the magnesium or magnesium alloy and the different metal to a temperature at or below which neither of the magnesium or magnesium alloy and the different metal is molten. This treatment provides a boundary layer between the aluminum film and the magnesium or magnesium alloy. This boundary layer is free from pinholes running from the interface of the aluminum film and the boundary layer to the magnesium or magnesium alloy ground. This surface-treated magnesium or magnesium alloy has excellent corrosion resistance surface electric conductivity, thermal conductivity and heat shock resistance.Type: GrantFiled: September 22, 1989Date of Patent: November 27, 1990Assignee: Nippon Telegraph and Telephone Corp.Inventors: Masato Mino, Goro Yamauchi, Kishio Arita

Patent number: 4896116Abstract: An object detection method and apparatus in which, in order to distinguish only an echo wave which is returned back from an object of interest, such as an underground buried object, from those echo waves returned back from another object of objects, the observation signal is divided (an electromagnetic wave as an echo wave) into portions, and the signal portion is converted into a corresponding frequency region to evaluate that spectral distribution and computes frequency parameter values from the spectrum distribution. The object of interest is detected by comparing the reference data of various fields with the parameters of the object of interest, extracting only an echo wave returned back from the object of interest and displaying a corresponding image.Type: GrantFiled: May 23, 1988Date of Patent: January 23, 1990Assignee: Nippon Telegraph and Telephone CorporationInventors: Yuji Nagashima, Yoshikazu Sudo, Junichi Masuda, Yuzo Matsudaira, Kishio Arita, Eiji Nagai

Patent number: 4770946Abstract: An oxidized film is formed on the surface of Mg or an Mg alloy, and a thermosetting resin film is formed on the oxidized film. A conductive film is further formed on the thermosetting film. The surface film of the Mg or Mg alloy thus surface-treated has a strong adhesion to the Mg or Mg alloy. The surface-treated Mg or Mg alloy has an excellent corrosion resistance, an excellent heat shock resistance, and a high surface conductivity.Type: GrantFiled: April 30, 1986Date of Patent: September 13, 1988Assignee: Nippon Telegraph and Telephone CorporationInventors: Goro Yamauchi, Kishio Arita, Junichi Seki, Eiichi Sakita, Masato Mino, Yuzo Matsudaira, Ryozi Takekoshi, Yoshimori Miyata, Junichi Masuda, Yoshitaka Koide
