  • Medicament for hypothermia treatment
    Patent number: 6210697
    Abstract: A medicament containing human growth hormone (hGH), which can prevent or decrease the immunosuppression and the onset of infectious diseases such as pneumonia in a hypothermia treatment that has been recognized to show remarkable effects on the lifesaving and/or the improvement of recovery of a patient with serious cerebral injury, and thereby contributing to the expansion of the range of application and the improvement of lifesaving effect of hypothermia treatment.

  • Method and apparatus for producing diamond thin films
    Patent number: 5258206
    Abstract: The present invention concerns a method of producing a diamond thin film. A plasma-activated gas, obtained by exciting a starting material containing a carbon source gas, is brought into contact with a surface of a substrate, on which a diamond thin film is to be formed under the presence of an auxiliary member placed adjacent to a protruded portion present at the surface of the substrate. The diamond thin film is thereby formed on the substrate. An apparatus for producing a diamond thin film by means of a microwave plasma method has an auxiliary member placed adjacent to a protruded portion present at the surface of the substrate on which the diamond thin film is to be formed.

  • Diamond-coated member and process for the preparation thereof
    Patent number: 5135807
    Abstract: The present invention relates to a diamond-coated member characterized by superposing an acicular diamond layer, an intermediate layer formed by a metal belonging to either of the group IIIb, IVa, Va or VIa of the periodic table or by a compound containing the said metal, Si or B, and a non-acicular diamond layer on the surface of a base material and to a process for the preparation of a diamond-coated member characterized in that a diamond layer is formed on the surface of a base material by vapor phase synthesis method; the resulting diamond layer is converted into acicular diamond by exposing the resulting diamond layer to a gas obtainable by exciting an oxygen-containing etching gas; an intermediate layer comprising a metal belonging to either of the group IIIb, IVa, Va or VIa of the periodic table or by a compound containing the said metal, Si or B is formed on the resulting acicular diamond; and the resulting intermediate layer is exposed to a gas obtainable by exciting a raw material gas containing a c
