摘要： A method for producing a group 13 nitride single crystal includes dissolving and crystal growing. The dissolving includes dissolving nitrogen in a mixed melt in a reaction vessel that contains the mixed melt, a seed crystal, and a surrounding member. The mixed melt contains an alkali metal and a group 13 metal. The seed crystal is a seed crystal that is placed in the mixed melt and includes a group 13 nitride crystal in which a principal face is a c-plane. The surrounding member is arranged so as to surround the entire area of a side face of the seed crystal. The crystal growing includes growing a group 13 nitride crystal on the seed crystal.

摘要： A method is designed for recording contents information along a track of an optical disk of a writeable type. A volume detection step is carried out for detecting an actual volume of the contents information to be recorded into the optical disk. A capacity detection step is carried out for detecting a nominal capacity of the optical disk, which indicates a rated volume of information to be recorded at maximum. A density determination step is carried out for determining a recording density of the contents information based on the detected actual volume and the detected nominal capacity. A recording step is carried out for recording the contents information into the optical disk at the determined recording density such that the actual volume of the contents information can fit into the nominal capacity of the optical disk.

摘要： A structure of a substrate used for growing a crystal layer of a semiconductor, particularly a group-III nitride semiconductor and its manufacturing method. The substrate comprises two porous layers on a base. The mean opening diameter of the pores of the first porous laser, the outermost layer, is smaller than the means diameter of the pores in the second porous layer nearer to the base than the first porous layer. The first and second porous layers have volume porosities of 10 to 90%. More then 50% of the pores of the first porous layer extend from the surface of the first porous layer and reach the interface between the first and second porous layers. Even by a conventional crystal growing method, an epitaxial crystal of low defect density can be easily grown on the porous substrate.

摘要： A visible image is formed on an optical disk by using an optical disk recording apparatus that forms a pit with a length defined by recording data (EFM-modulated data) by applying a laser beam onto the optical disk. At least a part of the recording data are replaced with the visible image forming data to generate the recording data containing visible image forming data. When the recording data containing the visible image forming data are recorded on the optical disk, the visible image forming data are extracted from the recording data to act as a gate signal. The visible image is formed by forming a pit defined by the recording data in an area of the gate signal.
