  • Publication number: 20050150360
    Abstract: A play data editing device edits play data according to a characteristic of a speaker. The play data editing device includes a dividing unit (301) for dividing first play data into second play data per channel; a classifying unit (302) for classifying the second play data into a rhythm part, a melody part, and a base part; a chord processing unit (303) for converting a number of chords of the second play data corresponding to the melody part according to the characteristic of the speaker; a velocity processing unit (304) for converting a velocity of the second play data corresponding to the rhythm part according to the characteristic of the speaker; and a sound range processing unit (305) for shifting a sound range of the second play data corresponding to the base part according to the characteristic of the speaker.

  • Publication number: 20040173084
    Abstract: A music playback unit for correcting the frequency characteristics of a speaker installed in a portable telephone, without using an equalizer. The musical score data is stored in the SMF memory, and data for correcting the velocity of musical score data for each velocity of each note is stored in a DB memory. The sound generator driver reads the musical score data from the SMF memory, and reads the correction data from the DB memory, and also corrects the velocity of the musical score data by substituting the musical score data and correction data in a predetermined calculation formula. The musical score data after the velocity is corrected is played by the MIDI sound generator, amplifier and speaker.

  • Patent number: 6455199
    Abstract: Graphite powder for a negative electrode in prior arts, which allows lithium ions to repeat intercalation and deintercalation reversibly by charge and discharge, has failed to attain a specific capacity close to the theoretical capacity of 372 mAh per 1 g. Also, there was a problem in storage property at a high temperature when it is attempted to improve the high rate charge and discharge characteristics. An object of the present invention is to solve these problems. In the process of pulverizing flaky graphite particles of which plane interval (d002) of (002) plane is 3.350 to 3.
