The present disclosure provides an inorganic-organic hybrid film which is excellent in transparency, adhesion, heat resistance, weatherability, and anti-rust property, whose refractive index may be controlled easily, and which is also excellent in hardness. Also provided are an inorganic-organic hybrid composition as a starting material for the film, and a hard coating material, an optical material, an anti-rust coating material, and a conductive coating material, all utilizing the composition. The composition is characterized by containing organic component (A) composed of monomer component (a1) containing a particular diol (meth)acrylate compound (U) having a urethane bond, or polymer component (a2) containing polymer (P) obtained by polymerization of monomer component (a1), and inorganic component (B), wherein the ratio of the organic component (A) to the inorganic component (B) is 1:99 to 99:1 by mass.

A mobile radio communication system estimates the positional relationship between an own moving terminal and another moving terminal around a view obstruction. If the absolute value of the difference between detected reception power levels is lower than a first power threshold value, the own moving terminal determines that the other moving terminal is positioned within the visual range of the own moving terminal, the distance from the own moving terminal to the other moving terminal being shorter than a predetermined distance B, or that the other moving terminal is positioned outside thereof, the distance to the visual range of the own moving terminal being shorter than the predetermined distance B. Also if the absolute value is higher than or equal to the first power threshold value, the own moving terminal determines in a similar manner.

A method for preparing a high-pressure phase cubic spinel-type silicon nitride includes housing a molding containing low-pressure phase silicon nitride powder and a metal powder in a cylindrical container, arranging an explosive in the cylindrical container so as to surround the molding, and exploding the explosive to compress the molding. An X-ray diffraction pattern of the high-pressure phase cubic spinel-type silicon nitride produced according to the method of the present invention shows a maximum peak having a full width at half maximum of 0.65 degrees or less. TG-DTA analysis of the cubic spinel-type silicon nitride shows a weight change starting temperature of 700 to 1100&#xb0; C.

High-pressure phase silicon nitride having a cubic spinel structure and the manufacturing method

The present invention relates to a method for manufacturing a highly purified diamond. In the method, a copper powder having purity 99.8% or more and having an acid-insoluble impurity concentration at 50 ppm or less, and graphite are mixed at first. The mixture of the copper powder and graphite is loaded into a sample tube. The sample tube is placed in an explosive tube. Explosive is loaded in the surrounding of the sample tube. Graphite is shock-compressed by the detonation of the explosive to yield diamond.
