  • Patent number: 5052734
    Abstract: A cargo container lifting spreader compensating mechanism for facilitating engagement by the spreader with cargo containers having out-of-plane twistlock engagement receptacles, the invention comprising cross-members for carrying the twistlock lug members secured at the ends of the spreaders with rotatable connections whereby they are partially rotatable in a vertical plane perpendicular to the longitudinal axis of the spreader with a restrictor means to limit said rotation.

  • Patent number: 5051787
    Abstract: A superconductor storage device and a memory constructed by arranging a plurality of superconductor storage devices are disclosed. The superconductor storage device is comprised of a word line, a write-in line, a first loop of superconductor composed of two branch paths of superconductor connected to the word line so as to allow a current flowing in the word line to be retained in the first loop, a weakly coupling portion inserted in at least one of the two branch paths, the weakly coupling portion being subject to the influence of a magnetic field generated by the write-in line to control the retention of the current in the first loop, and a second loop of normal conductor provided so as to be magnetically coupled with the first loop, the second loop including an input path and an output path which allow the application of a voltage to the second loop and two branch paths of normal conductor which makes a loop-wise connection between the input path and the output path.

  • Patent number: 4936841
    Abstract: Disclosed is a fluid container having a flexible bag containing a diluent and having a closing film at its upper end, a capsule connected to the flexible bag, a drug container held in the capsule and a communicating member for communicating the flexible bag with the drug container. The communicating member has a double-edged hollow needle having a hub in the midway thereof, and a controlling mechanism for controlling the order of communication in such a manner that the plug of the drug container is stuck with one edge of the needle and thereafter the closing film of the flexible bag is stuck with the other end of the needle. The mixing procedure is sure and simple, and can be carried out in a short period of time.

  • Patent number: 4935625
    Abstract: An electron holography apparatus includes an electron microscope which is provided with an electron source, a beam splitter for dividing an electron beam emitted from the electron source into first and second electron beams, and a phase controller for controllably changing a phase difference between the first and second electron beams, and further includes an image detector for detecting an electron interference fringe pattern which varies in accordance with the phase difference between the first and second electron beams, as a picture image, and an image data processor for determining the phase distribution of one of the first and second electron beams from detected image data.

  • Patent number: 4724320
    Abstract: A method for observing the arrangement of atoms in a thin layer on a surface and an apparatus for employing the method are disclosed. According to the method, a finely converged electron beam is directed to a surface of a sample and the X-ray emitted from the surface is detected at a take-off angle equivalent to, or in the vicinity of, the total reflection angle, thereby avoiding interference from X-rays emitted beneath the surface. The apparatus includes an electron gun, a sample holding means, one or more detectors and devices for storing, processing and displaying the output signal from the detectors. The apparatus also provides for two-dimensional scanning of a surface and for adjustment of the position of the sample and of the detectors.
