摘要： Provided is a group-III nitride semiconductor laser device with a laser cavity enabling a low threshold current, on a semipolar surface of a support base the c-axis of a hexagonal group-III nitride of which tilts toward the m-axis. In a laser structure 13, a first surface 13a is a surface opposite to a second surface 13b and first and second fractured faces 27, 29 extend each from an edge 13c of the first surface 13a to an edge 13d of the second surface 13b.

摘要： There is provided a system capable of distributing code-compressed data based on audio data on a music composition via the Internet to a mobile telephone so that a user can cut out a desired range from the code-compressed data and register it as a call sound. The system has a data structure of a content frame (3GPP, 3GPP2) containing code-compressed data (AAC) of audio data. The content frame has at least one cut-out position information in the AAC data in its extended function section. A mobile telephone has a content storage unit, a cut-out selection unit to be used by the user to select at least one cut-out position information contained in the extended function section of the content frame, and a data cut-out section for cutting out data from the code-compressed data. The code-compressed data which has been cut out is decompressed when called and the sound is outputted from a loudspeaker.
