    摘要: Disclosed are a method and an apparatus for detecting a defect in a dielectric film. The dielectric film is electrified in an electrolyte solution containing a metal in such a manner the dielectric film is charged negative, thereby the metal is deposited on the dielectric film at a position corresponding to the defect. The detecting method has a first deposition step for forming a first metal deposit on the dielectric film in an annular form surrounding the position corresponding to the defect; and a second deposition step for forming a second metal deposit located on the position corresponding to the defect, on the dielectric film. The detecting apparatus has a vessel for accommodating the electrolyte solution; a first electrode for electrifying the dielectric film and a second electrode; and an electric power source for controlably applying a voltage to electrifying between the first electrode and the second electrode in which a value and a direction of the applied voltage is variable.

    摘要: A tubular single-layer winding coil is installed on the outer periphery of a thin wall portion of a cylindrical container case and a columnar electrode is provided at the center of the inside of the cylindrical container case. A fuel channel is formed between the coil and the electrode so that the permittivity of fuel flowing through the fuel channel is detected from the electrostatic capacity therebetween. Further, variation of the electrostatic capacity due to the temperature characteristics of the fuel is compensated by the temperature characteristics of the permittivity of the thin wall portion of the sensor unit. Furthermore, variation of the electrostatic capacity due to the temperature characteristics of the fuel is compensated by the temperature compensation capacitor which is connected with the single layer winding coil in parallel.

    摘要: A sintered silicon nitride excellent in high temperature performance is produced by the following method: First, silicon nitride powder and oxide of at least one element selected from elements in the group IIIb of a periodic table are mixed with each other to obtain a mixture. The silicon nitride powder contains silicon oxide in an amount ranging from 0.1% by weight of the silicon nitride powder to a value not more than a content of the silicon oxide. Second, the mixture is compacted to form a compact. Finally, the compact is fired in atmosphere of nitrogen at a pressure ranging from 5 to 200 atmosphere (atm) and a temperature ranging from 1800.degree. to 2000.degree. C. to obtain a sintered silicon nitrite having a bulk density not less than 95% of a theoretical density of the sintered silicon nitride.
