  • Pulse radar method and apparatus for detecting an object
    Patent number: 4896116
    Abstract: 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.

  • Surface-treated magnesium or magnesium alloy, and surface treatment process therefor
    Patent number: 4770946
    Abstract: 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.
