A process for producing a superconductor of an oxide system, which comprises uniformly mixing metal elements for constituting the oxide system at least partly in the form of acetylacetonates in a solvent with the rest, if any, being in the form of alkoxides, carboxylates and/or inorganic salts, hydroxides and/or oxides to obtain a homogeneous mixture, and sintering the mixture.
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.

A capacitor for memory devices including a barium strontium titanate system dielectric film, the film being formed from a chemical vapor deposition source material including a liquid solution of respective organometallic compounds of barium, strontium, and titanium dissolved in tetrahydrofuran.
摘要:
The multi-source raw material are dissolved in the tetra-hydrofuran, in a liquid state and evaporated simultaneously and stably transported to the reactor, thereby the dielectric thin film used for capacitor having a good performance is formed with a good repeatability. The present invention provides CVD raw material for oxide-system dielectric thin film wherein organic metal raw material is dissolved in the tetra-hydrofuran and the metal atom of the organic metal raw material is selected at least among Pb, Ti, Zr or alkaline earth metal. As a result, a stable dielectric thin film can be formed by CVD method and the dielectric thin film can be used for a capacitor for memory devices.
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.
