A hazardous substance treatment agent has a retainer and a transition metal oxide. The retainer has the specificity of retaining only a specific hazardous substance, such as a virus, a bacterium or a toxin, that has become mixed in or has the possibility of becoming mixed in a treatment subject, such as blood, that is in at least either a liquid or gaseous phase. By a photocatalytic action, the transition metal oxide inactivates said hazardous substance retained by the retainer.

Method and apparatus for measuring a surface temperature of an object body, by calculating a temperature at each picture element of an image of the object body, on the basis of a radiant intensity ratio at each pair of corresponding picture elements of a first and a second image which are obtained with respective radiations having respective first and second wavelengths which are selected from a light emitted from the surface of the body, by a first filter which permits transmission therethrough a radiation having the first wavelength which is selected according to a radiant intensity curve corresponding to a wavelength of a black body at a lower limit of a temperature measurement range, and which is within a high radiant intensity range in which the radiant intensity is higher than a radiant intensity at a normal room temperature, and a second filter which permits transmission therethrough a radiation having the second wavelength which is selected within the high radiant intensity range, such that the second wavelength is different from the first wavelength by a predetermined difference which is not larger than &frac13; of the first wavelength and which is not smaller than a sum of half widths of the first and second wavelengths.

A method of measuring a temperature of an object body in an electric furnace, based on an intensity of a radiant energy emitted from the object body, the electric furnace being provided with an electric heater operable by application of a drive voltage thereto to heat the object body, the method comprising: a radiant-energy detecting step of detecting an intensity of a radiant energy emitted from the object body; a stray-light noise eliminating step of determining as a noise an intensity of a radiant energy of a stray light which is emitted from an inner wall surface of the electric furnace toward the object body and reflected by a surface of the object body, according to a predetermined relationship between the intensity of the radiant energy of the stray light and the drive voltage applied to the electric heater and based on an actually applied value of the drive voltage, and subtracting the intensity of the radiant energy of the stray light determined as the noise, from the detected intensity of the radiant energy emitted from the object body; and a temperature calculating step of calculating a temperature of the object body, based on the intensity of the radiant energy emitted from the object body from which the noise has been removed in the stray-light noise eliminating step. Also disclosed is an apparatus for practicing the method, which may include a shielding device disposed between the furnace walls and the object body.

Carbon fiber reinforced silicon nitride based nanocomposite material is produced by mixing a powder mixture of silicon nitride powders (with or without alumina powders), and fine silicon carbide powders, with a solution of a preceramic polymer containing silicon and nitrogen, to form a solution for impregnation, by passing carbon fibers through the solution to produce a mass of impregnated carbon fibers, forming the mass to a desired shape and by sintering in an inert atmosphere. Ultra-high strength and toughness are produced due to reinforcement by nanocompositization of the matrix phase, that by dispersion of fine particles and that by long carbon fibers, part of matrix phase is generated by thermal cracking of preceramic polymer.
