  • Patent number: 11990771
    Abstract: A method for wireless power transmission includes obtaining, via a Q-value circuit, first and second voltages at respective first and second nodes of a resonance circuit. The first and second voltages are effective to determine if foreign matter is present in a space affecting wireless power transmission. The method includes controlling a switching section between the Q-value circuit and the resonance circuit such that at least a part of the electric power transmission process occurs at a different time than when the first and second voltages are obtained.

  • Publication number: 20050014236
    Abstract: L-arginine or L-lysine is produced by culturing a coryneform bacterium having an L-arginine- or L-lysine-producing ability and modified so that glutamine synthetase activity is enhanced, e.g., a coryneform bacterium which is modified so that adenylylation of glutamine synthetase is eliminated.

  • Publication number: 20030124686
    Abstract: Disclosed is a coryneform bacterium having L-arginine-producing ability in which an activity of intracellular argininosuccinate synthase is enhanced, wherein the activity of intracellular argininosuccinate synthase is enhanced by, for example, increasing copy number of a gene which codes for an argininosuccinate synthase derived form a coryneform bacterium in the bacterial cell, or modifying an expression regulation sequence for the gene in the bacterial cell so that expression of the gene should be enhanced. L-Arginine is produced by culturing the bacterium having L-arginine-producing ability in a medium so that L-arginine should be produced and accumulated, and collecting the L-arginine from the medium. The present invention provides a coryneform bacterium of improved L-arginine-producing ability and an efficient method for producing L-arginine.
