  • Publication number: 20100271711
    Abstract: The present apparatus includes: a light emitting portion for emitting a detection-receiving light; a light emitting portion arranged parallel to the light emitting portion for emitting a detection-receiving light; a reflecting plate which is moved relative to the light emitting portions along their parallel arranged direction and also includes an optical pattern where a white area and a black area having a reflectance different from the white area with respect to the detection-receiving lights and are arranged alternately; and a light receiving portion which, according to the light intensities of the detection-receiving lights to be reflected by the reflecting plate, outputs output voltage signals. A controller selects one of the output voltage signals as a position detecting signal and obtains information about the position of a moving lens movable in linking with the reflecting plate.

  • Publication number: 20100271700
    Abstract: Abnormal noise generated while driving a piezoelectric actuator is prevented. A pulse-generation circuit is capable of selectively generating a displacement pulse and a stationary pulse as a drive pulse for application to a piezoelectric element, the displacement pulse having a duty ratio for causing a lens to be displaced by a predetermined step width, and the stationary pulse having a duty ratio for causing the lens to remain stationary in a current position. The pulse-generation circuit controls the production of the drive pulse continuously for a plurality of times within the servo control cycle, causes the displacement pulse to be produced when the remainder of a required amount of displacement is equal to or greater than a threshold value, and causes the stationary pulse to be continuously produced until the initiation of the next servo control cycle when the remainder is less than the threshold value.

  • Patent number: 7608437
    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 so that it is close to a consensus sequence or introducing a change in the promoter sequence of amino acid- or nucleic acid-biosynthesizing genes on the chromosome of a coryneform bacterium by gene recombination so that it is close to a consensus sequence, obtaining mutants of the coryneform amino acid- 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 allows one of skill in the art to construct a mutant capable of enriching or controlling the expression of an intended gene without using a plasmid and to promote production of amino acids in a high yield, by the recombination or mutation.
