  • Patent number: 4938322
    Abstract: A damper comprising within a casing filled with viscous fluid a number of movable discs to be moved in response to the transmitted external force and a number of not interlocked fixed discs arranged in an alternative arrangement, wherein both movable and fixed discs are axially deflectable can maintain even clearances between the movable and the fixed discs due to the alignment effect of the discs without undergoing unreasonable stress that can damage the discs. The allowable limit of deflection of the fixed and movable discs can be made adjustable so as to modify the total drag of the damper. Sources of resilient restoring force may be provided to enhance the capability of adjustment. Moreover, the number or the size of the movable and/or the fixed discs can be made alterable to effectively modify the drag of the damper.

  • Patent number: 4931649
    Abstract: A spectrometer for MEV neutrons relies upon total energy absorption to measure neutron energy. Neutrons are thermalized in a liquid scintillator-moderator providing a first light pulse and are subsequently captured in a Li-6 glass scintillator providing a second light pulse. The light pulses are converted into first and second electronic signals by photomultipliers. A coincidence signal is required from the neutron capture prior to gating electronic circuitry for measuring the amplitude of the first electronic signal. The dual signal from a single neutron provides a mechanism for discrimination against background events arising either from gamma rays or from ambient, low-energy neutrons. The spectrometer is particularly useful in situations in which the neutron source intensity is very low.

  • Patent number: 4930088
    Abstract: A rotated pattern generating system includes at least a X-direction straight line generator adapted to calculate, a difference in X- and Y-directions between the position of a given dot on a destination coordinate and a position of the next dot to be coordinate transformed. The difference is determined by the difference on the source coordinate between the given dot and the next dot to be transformed and a required rotational angle .theta.. The system further comprises a detector connected to the X-direction straight line generator for discriminating whether or not a residual pattern occurs each time the X-direction straight line generator generates an output, and a dot generator responsive to the output of the detector to generate, when a dot lack is discriminated on the position of the residual pattern the same dot information as that of the dot adjacent to the residual pattern position in the destination coordinate.
