    摘要: The capacitor according to the present invention comprises a lower electrode 18 formed on a base substrate 14, a dielectric film 20 formed on the lower electrode 18, and an upper electrode 28 formed on the dielectric film 20 and including a polycrystalline conduction film 22, and a amorphous conduction film 24 formed on the polycrystalline conduction film 22. Because of the amorphous conduction film 24 included in the upper electrode 28, which can shut off hydrogen and water, hydrogen and water can be prohibited from arriving at the dielectric film 20. Accordingly, the dielectric film 20 of an oxide is prevented from being reduced with hydrogen, and the capacitor can have good electric characteristics.

    摘要: Provided is a turbocompressor (4) having a drive part (12) generating rotational power, an impeller (22a) to which the rotational power of the drive part (12) is transmitted to rotate, a plurality of gears (31, 32) transmitting the rotational power of the drive part (12) to the impeller (22a), and a drive part casing (13) in which the drive part (12) is installed. This turbocompressor (4) includes an impeller casing (22e) installed around the impeller (22a), and a gear casing (33) configured to be formed independently of the impeller casing (22e) and the drive part casing (13), to couple the impeller casing (22e) and the drive part casing (13), and to form an accommodation space (33a) in which the plurality of gears (31, 32) are accommodated. With this configuration, in manufacturing the turbocompressor, a working process can be simplified and working labor and cost can be reduced.
