  • Patent number: 5479024
    Abstract: A near-field optical microscope and method of microscopy in which a probe including a flexible cantilever having a sharp tip is positioned in proximity to a sample. In one embodiment, a region of the sample is irradiated with light, and one or more portions of this region are caused to fluoresce. A quenching element is provided at the tip of the probe to quench the fluorescence of these portions within the region. The amount of quenching is determined while the sample is scanned to produce a high resolution image of the irradiated region of the sample. In another embodiment, the fluorescence imparted to one or more portions of the irradiated region is enhanced by the interaction of an optically active element disposed at the tip portion of the cantilever probe which provides for sharper images with greater signal-to-noise ratios.

  • Patent number: 5193319
    Abstract: Given is a formed partition made of displaceable wall elements that are suspended, by means of carrier studs, on two carrier members that are displaceable in guide rails, and movable along their perpendicular interfaces in sealing contact against one another and/or against terminal elements. Situated on the horizontal interfaces of the wall elements are sealing strips that are capable of being extended in contact against the floor and/or the guide rails or the ceiling of the room. On one of the wall elements, one of the carrier studs is journaled in horizontally-displaceable fashion toward the other carrier stud. In order to be able to execute a simple and rapid transport of the wall elements, even diagonally, running in the guide rail is a drivable endless element to which are fixed, at a predetermined interval apart, two followers.
