  • Patent number: 9601772
    Abstract: The present invention provides a cathode active material that makes possible a high capacity nonaqueous electrolyte secondary battery that has excellent discharge load characteristics that provide both good cycle characteristics and thermal stability. The cathode active material comprises a lithium nickel composite oxide having the compositional formula LiNi1?aMaO2 (where, M is at least one kind of element that is selected from among a transitional metal other than Ni, a group 2 element, and group 13 element, and 0.01?a?0.5) to which fine lithium manganese composite oxide particle adhere to the surface thereof. This lithium nickel composite oxide is obtained by adding manganese salt solution to a lithium nickel composite oxide slurry, causing manganese hydroxide that contains lithium to adhere to the surface of the lithium nickel composite oxide particles, and then baking that lithium nickel composite oxide.

  • Patent number: 8305856
    Abstract: To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit (14). The EDC rewrite circuit (14) rewrites an error detection code appended to user data in each sector in accordance with bit information in the CPID bit block. Thereafter, the data in each sector is scrambled, and an ECC block including a plurality of sectors is modulated with an error correction code and sync signal appended thereto. The modulated signal is recorded in a reserve area of a lead-in area of the disk-shaped record medium. During reproduction, CPID is restored based on the result of error detection of each sector.

  • Publication number: 20120183006
    Abstract: After forming domain inverted layers 3 in an LiTaO3 substrate 1, an optical waveguide is formed. By performing low-temperature annealing for the optical wavelength conversion element thus formed, a stable proton exchange layer 8 is formed, where an increase in refractive index generated during high-temperature annealing is lowered, thereby providing a stable optical wavelength conversion element. Thus, the phase-matched wavelength becomes constant, and variation in harmonic wave output is eliminated. Consequently, with respect to an optical wavelength conversion element utilizing a non-linear optical effect, a highly reliable element is provided.

  • Patent number: 8193436
    Abstract: A method (100) and apparatus (200) are disclosed for transcribing a humming signal into a sequence of musical notes. The method begins by grouping (305) the signal into frames of data samples. Each frame is then processed to derive (320) a frequency distribution for each frames. The frequency distributions are processed to derive (410) a Harmonic Product Energy (HPE) distribution over the frames. The HPE distribution is then segmented (115, 120) to obtain boundaries of musical notes. The frequency distributions of the frames are also processed to derive (412) a fundamental frequency distribution. A pitch for each note is determined (125) from the fundamental frequency distribution.
