    摘要: A process for producing a superconductor of an oxide system, which comprises uniformly dissolving, dispersing or suspending in a solvent metal elements for constituting the oxide system at least partly in the form of carboxylates with the rest, if any, being in the form of alkoxides, acetylacetonates and/or inorganic compounds, followed by removal of the solvent to obtain a homogeneous mixture, and sintering the mixture.

    摘要: A method for making a photoconductive powder which comprises the steps of preparing fine particles of metal oxide or metal hydroxide by hydrolyzing a metal alkoxide or metal acetylacetonate; and immersing the fine particles into pigment containing suspensions to provide three types of composite particles. Each of the suspensions contains a respective pigment having a spectral absorption band within the wavelength region of a one of the primary colors of the additive principle. Each type of the resultant composite particles is composed of the fine particles of the metal oxide or metal hydroxide and the associated pigment as a principal component.

    摘要: A muffler of the absorption type for the exhaust gas of an internal combustion engine including a cylindrical porous sound-absorbing body 1, and a film 5 of a metal or other material formed cylindrically on the inner surface of the porous body 1. The film prevents clogging of the pores in the porous body and enables the absorption of the sound in a wide frequency range.
