Abstract: PROBLEM TO BE SOLVED: To provide a new Ge 3 N 4 nano belt, which will become very useful in the future of semiconductor nano technology and method of manufacturing the Ge 3 N 4 nano belt. SOLUTION: This Ge 3 N 4 nano belt has not a circular but a square cross section and long length and includes Ge 3 N 4 . This method comprises a step of mixing the powder of Ge and SiO 2 , and a step of covering this mixed powder with activated carbon particles, a step of heating the mixed powder with activated carbon particles in NH 3 atmosphere to make it grow into a form of Ge 3 N 4 nano belt and a step of cooling Ge 3 N 4 having a form of belt.

Abstract: PROBLEM TO BE SOLVED: To provide a novel nano thermometer which can be used for temperature measurement of a wide temperature range, in a micrometer size environment, and also to provided a method for producing the same. SOLUTION: The nano thermometer comprising a carbon nanotube filled with a continuous columnar gallium can measure environmental temperature by length change of the columnar gallium, and is produced by the method comprising mixing of Ge 2 O 3 powder and carbon powder uniformly, and performs heat treatment for this mixed powder at a temperature range of 1200 to 1400°C under an inactive gas flow.

Abstract: PROBLEM TO BE SOLVED: To manufacture hollow particulates of fullerene-shaped boron nitride containing no impurity and having uniform outside diameters by using carbon nanotube of uniform size as a starting raw material. SOLUTION: A method for manufacturing the hollow particulates of fullerene- shaped boron nitride is distinguished by that carbon nanotube is used as the raw material and is subjected to chemical reaction with an oxide of boron and nitrogen at high temperature of 1000 deg.C to 1500 deg.C. The oxide of boron used for the reaction is selected from boron oxide (B2O3), boric acid (H3BO3) and substances generating the oxide of boron at high temperature and is charged together with carbon nanotube into a crucible made of a boron nitride sintered compact, is laid in a high frequency induction heating furnace and is heated in gaseous nitrogen.
