Filed: 2002-09-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a contents reproducing device in which the inter-music blank is not unnecessarily long even when contents having license and contents having no license are coexistent.  <P>SOLUTION: The contents recording/reproducing device 10 includes a memory card 12 to reproduce a plurality of music data recorded on this memory card 12. For instance, the presence/no presence of the license and its validity are decided for all music data at the supply of a main power. The music having no license or the music having the license which is invalid is shifted to the end of a reproduction list, i.e. the pieces of music having the valid license are brought together to the top of the reproduction list. Since the pieces of music having the valid license are brought together, the identification of the license performed at the reproduction of each music can be made in a short period of time even when the pieces of music having no valid license are coexistent. Consequently, no discomfort is given to the user since the inter-music blank is not unnecessarily long.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a field emitter tip that is capable of maintaining an optimal performance by reducing the effect of contaminant or the like. SOLUTION: This is an improved spinned type field emitter tip (1410) and a method for manufacturing this field emitter. In order to sharpen the field emitter tip and to remove the contaminant absorbed from the surface of the field emitter tip, a film resistance heating element (502) is arranged toward the bottom of the field emitter tip and resistance heating of the field emitter tip is made possible. The metallic layers (1406-1409, 1602, 1604) of this improved field emitting device are separated by the relatively thick dielectric dual layers (1402-1405). The thickness of the metallic layers is thicker in the vicinity of the cylindrical well where the field emitter is piled.  The dielectric material is pulled back from the cylindrical aperture where the field emitter tip is piled so as to reduce the possibility of accumulation of conductive contaminant and short circuit between the metallic layers.
