    摘要: There is disclosed a pyrolytic boron nitride container used for a Boat method in which material melt is retained In the container, and a crystal is grown while a temperature gradient is imparted to the material melt. The transmissivity of the pyrolytic boron nitride container with respect to light at a wave number ranging from 3700 cm.sup.-1 to 6500 cm.sup.-1 has a profile such that the transmissivity monotonously changes in the longitudinal direction of the container. The transmissivity profile is produced by imparting a pressure profile during manufacture of the container through deposition of pyrolytic boron nitride, by roughing the outer surface of the container such that the surface roughness has a profile, or by compounding pyrolytic boron nitride with a different material. It becomes possible to facilitate generation of a temperature gradient in material melt within the container and to facilitate control of a temperature profile in the container.

    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: An object of the invention is to provide an image scrambling apparatus and an image descrambling apparatus capable of making a communication of secrecy by scrambling a digital image signal as well as variable-length-encoding the digital image signal.A transmitting apparatus 1 DCT-encodes an image signal V2 from an A/D converter 11 by means of a DCT encoder 12, and outputs signals of D1, D2, D3, D4, and the number of zero-runs D5. When it variable-length-encodes the D2 to D5 through a variable-length encoder 13 and outputs V3, it generates a series of PN signals K2 by means of a PN generator 18 on the basis of a PN initial value K1 from a PN initial value generator 17, adds the scalar quantumizing number D1 and K2 to each other by means of an adder 19 and outputs the scrambled D1, and then gives a scrambled image signal V4 through compositing the V3 and the D1.

    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.
