An element-specific imaging technique utilizes the element-specific fluorescence X-rays that are induced by primary ionizing radiation. The fluorescence X-rays from an element of interest are then preferentially imaged onto a detector using an optical train. The preferential imaging of the optical train is achieved using a chromatic lens in a suitably configured imaging system. A zone plate is an example of such a chromatic lens; its focal length is inversely proportional to the X-ray wavelength. Enhancement of preferential imaging of a given element in the test sample can be obtained if the zone plate lens itself is made of a compound containing substantially the same element. For example, when imaging copper using the Cu La spectral line, a copper zone plate lens is used. This enhances the preferential imaging of the zone plate lens because its diffraction efficiency (percent of incident energy diffracted into the focus) changes rapidly near an absorption line and can be made to peak at the X-ray fluorescence line of the element from which it is fabricated. In another embodiment, a spectral filter, such as a multilayer optic or crystal, is used in the optical train to achieve preferential imaging in a fluorescence microscope employing either a chromatic or an achromatic lens.

A container (10) with lower and upper parts of formed plastic sheeting, is constructed of two identical elements (12, 14) that can close and latch to each other to form a closed container by turning a second of the elements upside down to make it the upper element, and pressing it down against the lower first element. The lower element includes a base wall (20) which is the bottommost wall and which has a vertical axis (22), upstanding side walls (24), and a flange (30) extending radially away from the top of the side walls. Along a left half (34) of the lower element, the flange forms an upward projection(s) (42), and along the right half (36) of the lower element the flange forms an upwardly-opening groove (44). Each projection and groove extends in a zig-zag line along the flange.

Disclosed is a wire grommet intended to be positioned in a hole made into a surface of a panel or plate. The grommet is made of two identical elements having adjacent edges provided with tongues and grooves allowing them to be assembled to form an open container with a size and shape adapted to allow it to be inserted into the hole and be maintained within the same. The elements also have recesses in their edges which altogether form at least one opening through which one or more wires may pass when the elements are assembled. Advantageously, the wire grommet also comprises a closing cap fittable into both elements when the elements are assembled, in order to close the container formed by the same.

A transformation document generation mechanism (TDGM) for automatically generating a transformation document given a source document and a target document is disclosed. The TDGM analyzes each document and builds a pattern dictionary for each that records the patterns found in that document. Thereafter, the TDGM processes the pattern dictionaries to automatically generate the transformation document. In doing so, the TDGM automatically generates pattern creation templates in the transformation document. These templates (when invoked by a transformation processor at a later time while processing a source document with the transformation document) will cause particular patterns to be created in a result document. In addition, the TDGM generates zero or more copy templates in the transformation document to copy identical elements, if any, from the source document to the result document. Once that is done, the transformation document is created and may be refined by a user. By performing much of the underlying document analysis for the user, and by generating an initial transformation document, the TDGM simplifies the transformation document creation process.

The invention concerns an angular pneumatic gripper structure having a body (11) formed of two symmetric and identical elements or shells (15) realized and finished individually using a forming process and then associated and attached face to face to form together a housing chamber of an alternating piston (12) and a structure for receiving and guiding an intermediate drive (13) transversely and some grips (14) so as to turn driven by the piston through the drive. The elements or shells forming the body are made using die-casting, sintering or forging processes with material suitable for these forming techniques.

At least one edge (8; 10) of a structured packing element (4) is adapted to, or includes a means for, intermeshing with an adjacent edge (10; 8) of an adjacent structured packing element. Preferably, the at least one edge is a pair of opposite edges (8, 10) that intermesh with the respective opposed edge (10, 8) of an adjacent identical element (4) so as to permit the assembly of vertically stacked layers (2, 2', 2") of intermeshing packing.

Digital images that are produced by an image forming device may be processed using an edge enhancement technique to reduce the effects of halftone color depth reductions. For each element in the original image, certain detail elements are classified by examining the magnitude of pixel intensity gradients between elements of interest in a first window applied at each element and other elements in the first window. If a first predetermined condition is satisfied, those elements locations are stored. After halftoning, a morphological filter may be applied to the same element locations in the halftone image to enhance the halftone image.

An apparatus is disclosed wherein laser radiation illuminates a sample using all reflective optics and wherein in-elastically scattered light from the sample is collected using the identical elements. The apparatus obviates the problem of contaminating the laser radiation with unwanted spectra from transmissive optics while providing very high rejection of the laser radiation with respect to the in-elastically scattered light. In addition, the apparatus can collect and launch light with high numerical aperture and large field of view.

An apparatus consisting of two pairs of identical lenses which is suitable as a compound objective lens for high numerical aperture imaging is disclosed. The compound lens also has a wide field of view as a fraction of the compound lens focal length. By suitable choice of lens materials, well corrected near infrared imaging can be achieved. When two such compound lenses together with a diffraction grating are assembled into a spectrometer, excellent wavelength resolution in the near infrared can also be obtained.

When writing the shapes of elements of a fine pattern on a substrate by microscopically vibrating the electron beam back and forth in a radial direction of the substrate or in a direction orthogonal to the radial direction and deflecting the electron beam in a direction orthogonal to the vibration direction to scan the electron beam so as to completely fill the shapes of the elements, a proximity-effect correction is performed according to the arrangement density of the elements in which the amount of dose is adjusted by setting the deflection speed faster for the writing of an element in a densely arranged region than for the writing of an identical element in a sparsely arranged region.
