Abstract: An inflammation inhibiting agent was provided with. An inflammation inhibiting agent comprising a wavelength conversion substance as an active ingredient; a composition and a product comprising the inflammation inhibiting agent; and a method for inhibiting inflammation of skin using thereof were provided with. The present invention can exhibit a desirable effect on skin by effectively making use of ultraviolet light to inhibit inflammation in skin cells.

Abstract: The present invention provides a method and apparatus for locating the position of a lightning strike free of topography-dependent error by calculating a ground point having a difference in propagation distance at receiving stations (R1, R2 and R3) in at least three different locations. The difference in horizontal distance that would result in arrival time differences at the receiving stations is calculated using the horizontal coordinates of the respective stations. The ground point is taken as the tentative lightning strike position (X). The tentative lightning strike position is then corrected to a lightning strike position obtained by evaluating the arrival time difference in terms of the creepage distances (Ls) following depressions and elevations in the ground surface. The depressions and elevations in the ground surface are smoothed to a spatial wavelength that is comparable to the wavelength of the lightning electromagnetic waves.

Abstract: It is an object of the present invention to provide a lightning strike position locating method, apparatus, system and program that are free of topography-dependent error.

Abstract: Methyl chloride is prepared by effecting liquid-phase reaction between hydrogen chloride and methanol in the absence of a catalyst. The reaction is effected in divided stages including at least an early stage and a last stage. The early stage of reaction is effected in a stoichiometric excess of hydrogen chloride. The last stage of reaction is effected in a stoichiometric excess of methanol. The invention is industrially advantageous in that methyl chloride can be prepared at a high conversion of hydrogen chloride while suppressing the formation of dimethyl ether by-product.
