    摘要： A multilayer ceramic chip capacitor includes alternately stacked dielectric layers and internal electrode layers. The dielectric layers contain barium titanate as a major component and magnesium oxide, manganese oxide, barium oxide and/or calcium oxide, silicon oxide and optionally, yttrium oxide as minor components in such a proportion that there are present 0.1-3 mol of MgO, 0.05-1.0 mol of MnO, 2-12 mol of BaO+CaO, 2-12 mol of SiO.sub.2 and up to 1 mol of Y.sub.2 O.sub.3 per 100 mol of BaTiO.sub.3. The capacitor satisfies the standard temperature dependence of capacitance and shows a minimized change of capacitance with time under an applied DC electric field and a long insulation resistance life. Where the dielectric layers contain 0.1-3 mol of MgO, 1-5 mol of Y.sub.2 O.sub.3, 2-12 mol of BaO+CaO, and 2-12 mol of SiO.sub.2 per 100 mol of BaTiO.sub.3, the capacitor shows improved DC bias performance.

    摘要： A vibratory gyroscope including an elongated vibrator having a central (neutral) axis (Y-axis), a drive unit for deforming the first direction such that the vibrator vibrates in a first (X) direction, an added mass attached to the vibrator at a position offset from the central axis in a second (Z) direction, and a detector formed on the vibrator. Rotation of the vibratory gyroscope about the second (Z) direction during vibration in the second direction causes Coriolis force to acting on the added mass in a direction parallel to the central axis. Because the added mass is offset from the central axis, a resulting vibration in the second (Z) direction is produced, which is detected by the detector. With this arrangement, the central axis of the vibrator is placed in parallel with the surface of rotation of the rotating system. Thus, rotations about two or three axes in each direction can be detected in such a manner that noise generation is prevented.

    摘要： There is disclosed a pyrolytic boron nitride container for accommodating a material serving as a source of molecular beams for molecular beam epitaxy, wherein the transmissivity of the pyrolytic boron nitride container with respect to light having a wave number of 2600 cm−1 to 6500 cm−1 has a profile such that the transmissivity changes in the height direction of the container. The pyrolytic boron nitride container can be manufactured through a simple process and at low cost. The pyrolytic boron nitride container can prevent material melt from rising along the inner wall surface and prevent splashed material melt from adhering to the upper portion of the container. Further, the pyrolytic boron nitride container can stabilize molecular beam epitaxial growth and improve the quality of epitaxial film.
