  • Patent number: 6241045
    Abstract: A novel fall protection apparatus is described wherein a worker can climb a pole, while maneuvering about the pole as he climbs. This structure enables the worker to both ascend and descend, but be protected upon an accidental fall from the pole. In particular, the arrangement prevents the worker from falling more than a couple of feet, and at the same time holds the worker away from the pole by an amount sufficient to prevent injuries caused by banging into the pole. This structure is especially beneficial in training new workers to climb poles for work, as well as requalifying previously trained workers.

  • Patent number: 5515414
    Abstract: An X-ray diffraction device comprises a water-cooled X-ray tube which exhibits a line focus as well as, after rotation through 90.degree., a point focus. Contrary to customary X-ray tubes, the cooling water is not supplied via the housing (12) in which the X-ray tube is mounted, but the cooling water connections (52, 54) are provided directly on the X-ray tube at the same side of the robe where the high-voltage connector (16) is provided. As a result, rotation of the robe upon changing over from a line focus to a point focus is not hampered by cooling water connections inside the housing of the tube. An additional advantage of this method of supplying the cooling water resides in the fact that the robe base (56) can also be cooled via these ducts. The base would otherwise become inadmissibly hot due to the loss heat from the filament (60).

  • Patent number: 5510617
    Abstract: A primary beam in a scanning electron microscope (SEM) releases secondary electrons in the specimen to be studied. These electrons move back to the focusing lens against the direction of the primary beam, detection of these electrons taking place in the vicinity of said lens. A known detector comprises a Wien filter for deflecting the electrons from the optical axis to the actual detector. In accordance with the invention a SEM detector is provided with a double electric dipole. The latter leaves the primary beam undisturbed to a high degree, but very efficiently deflects the secondary electrons to the actual detector.

  • Patent number: 5511062
    Abstract: An apparatus having a frame (1) carrying a turntable (3) for supporting the information carrier, which turntable is rotatable about an axis of rotation (3A), a slide (9), which is movable between two end positions, with a scanning unit, guide spindles (5, 7) and a linear motor unit (17, 19) for the slide, and an electrically energizable clamping unit (21). In the non-energized condition the clamping unit clamps the slide in any arbitrary stationary position of the slide along its path and in the energized condition it does not clamp the slide. During operation of the device a control unit at least substantially simultaneously turns on a first energizing current to the motor drive unit and a second energizing current to the clamping unit at the beginning of a displacement of the slide and at least substantially simultaneously turns off the first energizing current and the second energizing current at the end of the displacement.

The insulating layer (3) is provided with contact windows (18) in which conductive elements (19) are provided. This is done from the first side (2) of the semiconductor slice (1) before the latter is fastened to the support slice (15). The semiconductor elements (5) are externally contacted with a contact wire (20) via the conductive elements (19).

  • Patent number: 5486480
    Abstract: A programmable transistor includes impurity regions to reduce punch-through and soft-write phenomena. In order to provide a fast operation, the impurity regions are arranged with regard to one another so that parasitic capacitances at junctions of impurity regions of mutually opposite conductivity type are minimized. For these purposes, the transistor comprises a charge storage region over a channel region in a main semiconductor zone of a first conductivity type located between a source and a drain of a second conductivity type opposite to the first. A first impurity zone of the first conductivity type, substantially laterally contiguous with the drain, extends into the channel region and is more heavily doped than the main zone. The drain includes a heavily doped third impurity region and a lightly doped second impurity region that lies at least mainly between the third region and the zones.

  • Patent number: 5466937
    Abstract: A method of forming an image in an electron microscope. Because of the oscillating behaviour of the phase contrast transfer function (PCTF), images made by means of an electron microscope are liable to exhibit contrast whereas the object does not exhibit such contrast. In order to counteract these deviations, it is proposed to form sub-images, each sub-image having its own defocusing of the imaging lens and each sub-image being formed with its own weighting factor, and to add said sub-images. A substantially flat variation of the PCTF is achieved by imparting an oscillating dependence as a function of the defocusing to the weighting factor. The invention offers a simple method of image reconstruction from the sub-images in that the value of the oscillating function has the same sign throughout the defocusing range. The desired image can then be obtained by addition of the sub-images on, for example a photographic film.

  • Patent number: 5450501
    Abstract: A scanning microscope comprises a system (2, 3, 4) for concentrating a radiation beam from a radiation source (1) to form a scanning spot on an object (5). The radiation from the scanning spot is projected by a second optical system (6, 7) onto a radiation-sensitive detection system comprising two detectors (8, 9). The signals from the detectors (8, 9) are combined into a difference signal 11 and a sum signal 13. These two signals are formed into a complex composite signal which is transferred to the frequency domain in a circuit 22 via a Fourier transform. By performing suitable filtrations on the composite signal in the frequency domain in the circuit 23, quantitative measurements can be performed on the amplitude and phase structure of the object 5. These measurements may be visualized after an inverse Fourier transform in the circuit 24 via an image-processing system 25 on an image display unit 26.

  • Patent number: 5447074
    Abstract: A strain-gauge transducer (5) comprising a substrate (10) provided with strain gauges and pressure members (11, 12) which deform the substrate (10) via transfer elements (1a, 4a) which transmit an applied force (F). The transfer elements comprise bars (1a, 1b, 4a, 4b) molded from an elastomer in a common molding operation. A material (2a, 3a) having a higher compressibility than the bars may be interposed between the bars. This material may form elastic stops (54a) provided to preclude breakage of the substrate. This results in a transducer whose sensitivity is linear for small loads and which is very insusceptible to overloading. The transducer can be used for the construction of scales or touch tablets.
