  • Patent number: 7556473
    Abstract: The present invention includes an inflow quantity regulating means 5 for regulating the inflow quantity of a fuel gas to a compressor 1; a recycle valve 7 for returning the fuel gas discharged from the compressor 1 to the inlet side of the compressor 1; and a control means which sets a control operating value for operating the compressor 1 at a predetermined operation point, and controls the inflow quantity regulating means 5 and the recycle valve 7 based on the control operating value. The control means has a first control signal generating means 27 which generates a signal increasing with an increase in the operating value as a control signal for the inflow quantity regulating means 5 when the control operating value is a predetermined value or larger and a second control signal generating means 29 which generates a signal decreasing with an increase in the operating value as a control signal for the recycle valve 7 when the control operating value is smaller than the predetermined value.

  • Publication number: 20060195702
    Abstract: A moving image distribution system, wherein the user can view content moving images at no charge, and the provider of the content moving images can prevent a drain of the moving image contents and can protect the copy right thereof, as a copy right holder, without fail. The moving images are divided, along a time axis, into two master and slave nonreproducible moving image files. The slave moving image file (small file) is encrypted based on CM file data in which a predetermined CM element has been incorporated. In response to a reproduction request of a user terminal that possesses the master moving image file (main file) in advance, the slave moving image file is distributed with the CM moving images to the user terminal via a network line such as the Internet.

  • Publication number: 20060003424
    Abstract: A method of producing coryneform bacteria having an improved amino acid- or nucleic acid-productivity comprises the steps of introducing a mutation in a promoter sequence of amino acid- or nucleic acid-biosynthesizing genes on a chromosome of a coryneform bacterium to make it close to a consensus sequence or introducing a change in a promoter sequence of amino acid- or nucleic acid-biosynthesizing genes on a chromosome of a coryneform bacterium by gene recombination to make it close to a consensus sequence, to obtain mutants of the coryneform amino acid d- or nucleic acid-producing microorganism, culturing the mutants and select a mutant capable of producing the intended amino acid or nucleic acid in a large amount. This method can construct a mutant capable of suitably enriching or controling the expression of an intended gene without using a plasmid and also capable of producing amino acids in a high yield, by the recombination or mutation.
