    • The development of a dielectric thin-film which is high (140 MV/cm or above) in product of dielectric constant .epsilon..sub.i and dielectric breakdown field strength E.sub.ib is essential for realizing an EL element which can operate stably at a low voltage. Such dielectric film is also required which can withstand heat treatments at high temperatures above 500.degree. C. and is proof against clouding and in which the electrical breakdown caused by a minute fault produced in the process of film formation is self-healed. A film material which satisfies all of these requirements could be obtained from a TiO.sub.2 -BaO based composition by partially substituting the position of Ti with Sn, Zr or Hf and also partially substituting the position of Ba with Ca or Mg. By using these dielectric films, it is possible to obtain a low-voltage drive thin-film electroluminescent element which are high in production yield and reliability.
    • 在介电常数εi和介电击穿场强Eib的乘积中高(140MV / cm以上)的电介质薄膜的开发对于实现能够在低电压下稳定运行的EL元件是必不可少的。 也需要这样的电介质膜,其能够承受高于500℃的高温下的热处理,并且防止混浊,并且其中由成膜过程中产生的微小故障引起的电击穿是自愈的。 满足所有这些要求的薄膜材料可以通过用Sn,Zr或Hf部分取代Ti的位置并且还用Ca或Mg部分取代Ba的位置,从TiO 2 -BaO基组合物获得。 通过使用这些电介质膜,可以获得高产率和可靠性的低电压驱动薄膜电致发光元件。

    • The present invention is directed to a gyroscopic instrument comprising concentric containers, the inner container enclosing a rotating electric gyro rotor, magnetic fluid enclosed between the inner and outer concentric containers, and magnetic flux producing means mounted on at least one of the two concentric containers, so that magnetic fluxes reach the magnetic fluid to support the inner container without contacting the outer container. The magnetic flux producing means are preferably mounted and oriented on a line drawn on at least one of the concentric containers at predetermined distances so that magnetic fluxes transmitted from the pole of one flux means reach the opposite pole of an adjacent means by passing through the magnetic fluid.
