  • Patent number: 7661401
    Abstract: A laser type ignition device for an internal combustion engine includes a laser oscillator mounted in the internal combustion engine so as to focus its laser beam on an air-fuel mixture supplied into the combustion chamber, a pressure sensor for detecting pressure in the combustion chamber, a power source for the laser oscillator and a control unit for controlling the power source to supply the laser oscillator with the current whose amount changes according to the pressure in the combustion chamber. The power of the laser beam increases as the pressure in the combustion chamber decreases to completely ignite the air-fuel mixture.

  • Patent number: 7501620
    Abstract: The present invention provides a laser irradiation mass spectrometer capable of analyzing components of living tissue or living cells with high accuracy. It includes a laser unit for irradiating a sample with a beam of laser light and controlling the irradiation spot of the laser beam on the sample; and a mass analyzer for performing a mass analysis of the ions generated at the irradiation spot, where the mass analyzer uses a frequency-driven ion trap and a time-of-flight mass spectrometer to carry out the mass analysis. The ion trap of this system assuredly traps ions having large mass to charge ratios, and enables the system to carry out analyses on samples of large molecules. Preferably, a digital driving method is used to drive the aforementioned frequency-driven ion trap. Also, a multi-turn time-of-flight mass spectrometer may preferably be used as the aforementioned time-of-flight mass spectrometer.

  • Patent number: 7025945
    Abstract: An anhydrous chloride with a formula of MCl2 (M=Fe, Co or Ni) is dissolved into an anhydrous acetonitrile solvent to form a chloride-acetonitrile solution. Then, calcium carbide minute powders are added and dispersed in the chloride-acetonitrile solution at a molar quantity equal to or smaller by 1–30 mol % than the molar quantity of the anhydrous chloride to form a reactive solution. Then, the reactive solution is heated at a predetermined temperature to chemically react the anhydrous chloride with the calcium carbide minute powders in the reactive solution to form a transition metal acetylide compound having an M-C2-M bond, a tetragonal structure, and a formula of MC2 (herein, M=Fe, Co or Ni).

    Abstract: An anhydrous chloride with a formula of MCl2 (M?Fe, Co or Ni) is dissolved into an anhydrous acetonitrile solvent to form a chloride-acetonitrile solution. Then, calcium carbide minute powders are added and dispersed in the chloride-acetonitrile solution at a molar quantity equal to or smaller by 1-30 mol % than the molar quantity of the anhydrous chloride to form a reactive solution. Then, the reactive solution is heated at a predetermined temperature to chemically react the anhydrous chloride with the calcium carbide minute powders in the reactive solution to form a transition metal acetylide compound having an M—C2—M bond, a tetragonal structure, and a formula of MC2 (herein, M?Fe, Co or Ni).

  • Publication number: 20050170181
    Abstract: An anhydrous chloride with a formula of MCl2 (M=Fe, Co or Ni) is dissolved into an anhydrous acetonitrile solvent to form a chloride-acetonitrile solution. Then, calcium carbide minute powders are added and dispersed in the chloride-acetonitrile solution to form a reactive solution. Then, the reactive solution is thermally treated (first thermal treatment) to form a nano-powder made of a transition metal acetylide compound having an M-C2-M bond, a tetragonal structure, and a formula of MC2 (herein, M=Fe, Co or Ni). Then, the nano-powder is thermally treated (second thermal treatment) again at a temperature higher than the temperature in the first thermal treatment to form a carbon layer-covering transition metallic nano-structure wherein a metallic core made of the transition metal M is covered with a carbon layer.
