Inventor: GUPTA CHAKRA V
IPC: H01B11/00
Filed: 1989-03-17
Abstract: A cable and method for making such cable is disclosed. The cable is especially suited for high frequency applications in which electrical attenuation and dissipation factor are of critical importance. The cable comprises a tubular outer conductor (14), and at least one inner conductor (11) for transmission of electrical signals. Between the inner and outer conductor is a foamed dielectric material (12). This dieletric is formed from the extrusion of an olefin polymer or a fluoropolymer with a blowing agent gas. Sulfurhexafluoride (SF₆), rather than environmentally unsafe chlorofluorocarbons, is used as a blowing agent to foam the dielectric (12).

Abstract: The cracking experienced during thermal cycling of metal:dielectric semiconductor packages results from a mismatch in thermal co-efficients of expansion. The non-hermeticity associated with such cracking can be addressed by backfilling the permeable cracks (33) with a flexible material (35). Uniform gaps between the metal (32) and dielectric materials (31) can similarly be filled with flexible materials to provide stress relief, bulk compressibility and strength to the package. Furthermore, a permeable, skeletal dielectric can be fabricated as a fired, multilayer structure having sintered metallurgy and subsequently infused with a flexible, temperature-stable material to provide hermeticity and strength.

Abstract: The invention relates to a method of continuously removing and obtaining ethylene diamine tetraacetic acid (EDTA) from the process water of electroless copper plating. For that purpose the process water containing the EDTA is directed into an electrodialysis cell alternatingly equipped with bipolar membranes and anion exchange membranes and/or cation exchange membranes, and to which a potential difference is applied. The EDTA is converted into its charge-neutral form by means of protonation, and the protons required for that purpose are generated via bipolar membranes through electrodialysis. The required pH-value is adjusted by a pH-controlled electric field regulation via the bipolar membranes.

Abstract: A radiation imaging apparatus provided with a detector array (10) comprising a plurality of detector units, each of which, in turn, comprises a plurality of X-ray detecting elements (S a , S b ,S c ) each having a photosensitive surface of a different area from those of the other elements and corresponds to one picture element or pixel of a display, the output signal from one or more of the X-ray detecting elements of each of the detector units being used as image information for a corresponding one of the pixels of the display. While the X-ray dose remains at a low level, the detection output from the detecting element having a large photosensitive surface or the sum of the output from that element and the outputs from the other elements having smaller photosensitive surfaces is used as pixel information to form an image of the object being examined. When the radiation dose increases to a predetermined high level, the result of detection by only the element having a small photosensitive surface is used as pixel information.

Abstract: Antigens from chlamydial organisms in specimens can be rapidly and sensitively determined using a polyamide microporous membrane which has surface hydroxy groups. This determination is accomplished by contacting extracted antigen with the polyamide microporous membrane for a sufficient time for the antigen to bind to the membrane. Antigen bound to the membrane is contacted with chlamydial antibody so as to form an immunological complex on the membrane. The presence of the complex on the membrane is then determined as a measure of the amount of chlamydial antigen present in the specimen. The use of this particular membrane improves reagent keeping and reduces background in the assay.

Abstract: A coin return control system for vending machines is dis­closed which includes predetermined coin type detecting portion for detecting the coin type predetermined by the coin type prede­termination switch every predetermined time. A memory memorizes the coin type detected by the coin type detecting portion immedi­ately after operating a particular switch except for the coin type predetermination switch. A variation detecting portion detects the variation of the coin type predetermined by the coin type predetermination switch based on the coin type detected by the predetermined coin type detecting portion and the coin type memorized by the memory. An instruction portion instructs the coin paying-out mechanism to return a coin from the auxiliary change retaining tube when the number of the coin retained in the change retaining tube corresponding to the coin type memo­rized by the memory is below a predetermined value. A determina­tion portion determines whether or not the instruction portion should instruct the coin paying-out mechanism to return a coin from the auxiliary change retaining tube based on the detected result of the variation detecting portion. Therefore, the coin return control system for vending machines can always correctly pay out a necessary coin.

Abstract: A method and a device are proposed for carrying out a value determination of the register difference on contours occurring in the printed image (for example letters in negative writing) by means of a colour video camera 2. The signal of the colour video camera 2 carrying the colour information is subjected to a colour separation in accordance with the printed colours occurring during printing. A contour, which has been produced by printing at least two printed colours on top of one another thus results in at least two separations in the corresponding printed colours. To determine the register difference, the offset from one part-image (separation) compared with the other part-image is now calculated. According to the device, a frame buffer 4, a colour separation computer 5, a colour separation memory 6 and an image computer 7 are provided in addition to a colour video camera 2.
