  • Information memory apparatus using probe
    Patent number: 7945962
    Abstract: In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator which moves a recording medium in the X direction is set higher than the lowest resonance frequency of an actuator which moves the recording medium in the Y direction. At the time of recording or reading information, the recording medium is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator.

  • Low NOx Combustor for Hydrogen-Containing Fuel and its Operation
    Publication number: 20110094239
    Abstract: An object of the present invention is to provide a gas turbine combustor that supports hydrogen-containing gas having a high burning velocity and is capable of performing low NOx combustion without reducing reliability of a burner. A first fuel nozzle is provided upstream of a combustion chamber and supplies fuel for activation and hydrogen-containing gas. The combustor has a primary combustion zone, a reduction zone and a secondary combustion zone. In the primary combustion zone, the fuel supplied from the first fuel nozzle is combusted under a fuel rich condition to form a burned gas containing a low concentration of oxygen. In the reduction zone, a hydrogen-containing gas is injected into the combustion chamber through a second fuel injection hole from a second fuel nozzle so that NOx generated in the primary combustion zone is reduced by an oxygen reaction of the hydrogen.
