  • Patent number: 8271112
    Abstract: A music information retrieval system of the present invention can retrieve unknown songs including singing voices having similar voice timbres. Voice timbre features of the songs and identifiers for the respective songs are stored in voice timbre feature storage section 2. When one of the songs is selected, similarity calculation section 3 calculates voice timbre similarities between the selected song and the respective remaining songs, based on voice timbre features of the selected song and the other songs. Similar song retrieval and display section 5 displays on a display 10 a plurality of identifiers for songs which are similar to the selected song in voice timbre. Song data reproduction section 6 reproduces song data corresponding to one or more identifiers selected from among the plurality of identifiers displayed on the display 10.

  • Publication number: 20120230973
    Abstract: Disclosed is a lactase preparation which does not undergo the deactivation of lactase even when the preparation is ingested prior to the ingestion of a lactase-containing food or drink such as a milk product and therefore can decompose lactase stably and which can prevent the symptoms of lactase intolerance. Specifically disclosed is a lactase preparation comprising lactase and at least one component selected from trisodium citrate, potassium sodium tartrate, calcium carbonate, sodium carbonate and calcium hydrogen phosphate which acts as an antacid. The lactase preparation is characterized by being intended to be ingested prior to the ingestion of a lactase-containing food or drink to decompose lactase. In the lactase preparation, the antacid is contained at such a content per unit dosage form that the pH value in the stomach can be increased to 4 or higher after the ingestion of the preparation.

  • Patent number: 7974494
    Abstract: Image control involves receiving source images defined with respect to respective source coordinate systems from source image generators also respectively associated with source IDs. The source images are composed to generate a composite image defined with respect to a composed coordinate system, and the composed image is sent to a viewer which displays the composed image and outputs an HID signal which indicates information defined with respect to the composed coordinate system. A layout manager stores source IDs respectively associated with layout information including position and size of at least one of the source images. An image composer composes the source images according to the layout information. An analyzer analyzes the HID signal for editing layout information stored in the layout manager, and determines a source ID a source image according to the layout information.

  • Patent number: 7885808
    Abstract: A pitch-estimation method, a pitch-estimation system, and a pitch-estimation program are provided, which estimate a weight of a probability density function of a fundamental frequency and relative amplitude of a harmonic component through fewer computations than ever. In the improved pitch-estimation method, 1200 log2 h and exp[?(x?(F+1200 log2 h))2/2W2] in the following expression are computed in advance and then stored in a memory of a computer: c ? ? ( t ) ? ( h ? F , m ) ? 1 2 ? ? ? ? W 2 ? exp ( - ( x - ( F + 1200 ? ? log 2 ? h ) ) 2 2 ? W 2 ) ( 61 ) The above expression is computed only with respect to a fundamental frequency F wherein x?(F+1200 log2 h) is close to zero. With this arrangement, computations to be performed may considerably be reduced, and computing time may accordingly be shortened.
