Patent EP-0425796-A2 (EP)
Inventor: FRANK VLASTIMIL
IPC: H01L21/50
Filed: 1990-09-10
Abstract: An induction heating module encapsulation apparatus and method for its use is disclosed. The apparatus comprises a substantially airtight chamber which is composed of ceramic or some other high temperature insulating material in which a cap (15) and a ceramic substrate (13) having semiconductor chips (11) joined thereon are placed. A sealband (17) of solder or other brazing material is placed at the periphery of the cap where the cap and substrate are to be joined. An RF coil (39), which serves as inductor in the apparatus, is energized by a high frequency generator, generating an electro­magnetic field in the radio frequency spectrum. The RF coil is oriented to localize the inducted current at the periphery of the cap and the sealband. The inducted current is dissipated in the form of heat until the sealband is molten. The RF power is then turned off. The chamber is pressurized at this point to prevent heated air underneath the cap from breaching the integrity of the sealband by escaping through the seal­band while it is in its molten state. After the sealband has been allowed to cool sufficiently to solidify, the pressure is reduced and the completed module is removed from the chamber. The entire encapsulation process requires ten to fifteen seconds per module assembly.

Abstract: Known rod antennas for radio traffic and for broadcast reception (VHF, S, M, L) do not have a sufficiently large bandwidth for specific applications. The invention is based on the object of developing a rod antenna in such a manner that the bandwidth of a rod antenna is increased in the direction of both higher and lower frequencies with low technical complexity. The object is achieved in that, starting from a 3/2  lambda  long rod of dielectric material, which contains a continuous coaxial inner conductor and is surrounded in its central region by a conductive coating, underneath which conductive coating (14) a further conductive coating (13) is provided. The further conductive coating has a length of approximately  lambda /2, in the same way as the central conductive coating (14). The coatings are intended to be at a distance (a) from one another and the lower end of the inner conductor (12) is intended to be conductively connected to the lower end of the further coating (13). The drawing shows a view of an antenna rod according to the invention. <IMAGE>

Abstract: A method for flow-through assay of  Chlamydia  includes digesting a sample suspected of containing  Chlamydia  with Proteinase K and passing the digested sample through a microporous membrane having an anti  Chlamydia  antibody adjacent an absorbent pad which promotes flow through the membrane by capillary action. Antigen bound to antibody on the membrane may be contacted with a specific anti  Chlamydia  monoclonal antibody conjugated to an enzyme and washed with a solution containing a chaotropic agent . Passage of a substrate for the enzyme through the membrane causes a detectable colored spot to appear on the membrane if the sample is positive for  Chlamydia.  The invention includes a reagent test kit for performing the assay.

Abstract: In a metallic mold, all or a part of the annular portion for molding at least the tread of the tire is formed by a plurality of small separate pieces (10, 11, 12) that can be combined to form said annular portion. Between these small pieces, during the molding of the tire, clearances are maintained so as to permit the passage of air but not the passage of rubber. The above clearances are connected through vent holes (20, 21, 22) to air suction means (40). Such vent holes are also connected with means (44) for blowing pressure fluid through the clearances. The construction of this mold portion by means of small pieces made with cuts of the aforementioned portion in the axial and the circumferential direction permits regulation of the width of the clearances with respect to the rheometric characteristics of the elastomeric material to be molded and to adapt easily the mold to different tire sizes by increasing or decreasing the number of such pieces.

Abstract: A plant monitoring and control system is specialized in a plant such as a reactor power plant, which is provided with plural process systems (A, B, ...N) functionally divided, and is communicable between the process systems with broadcast communication. Detection signals corresponding to process variables of the process systems, detected by the detectors (11A, 11B, ... 11N), are supplied into the transmission line (14) by the remote process input-output unit (13A, 13B ... 13N). Command signals can be also supplied into the line via a input unit (161A, 161B ... 161N) and a console controller (162A, 162B ... 162N) of a corresponding operator console (16A, 16B ... 16N). A corresponding process controller (15A, 15B ... 15N) takes in the detection signals and command signals from the line (14) and returns calculated control signals into the line. The remote process input-output unit (13A, 13B ... 13N) controls the corresponding process device (12A, 12B ... 12N) by giving the control signals. Each of the process controllers incorporates a control backup element against control failure of other process controllers, then eliminating the multiplex construction of the process controller (15A, 15B ... 15N) for a redundant system.

Abstract: The invention describes a frame for belt conveyors, comprising parallel T-grooved longitudinal spars which are located opposite one another at a distance and interconnected in one piece by means of an intermediate support, and the longitudinal spars can have fastened to them bearing plates for deflecting and/or driving rollers. Such a frame should be structurally simple, inexpensive to manufacture and keep in stock, and the fabrication should require minimum machining of the frame. This is achieved if at least one of the two free surfaces of the intermediate support is designed as a continuous sliding plane for the conveyor belt or as a bearing surface for a slide block and if the longitudinal spars each have, in the region of their outer lateral limiting faces and in the vertical position between the two free surfaces of the intermediate supports, a T-groove extending over the entire length.

IPC: G01S15/89

Abstract: An object (115 and 120) is tested for defects by interferometry, by comparing images of the object taken under stressed and unstressed conditions. The stress is applied by perturbing the object with acoustic waves, produced by a speaker (110) directed towards the object, without any mechanical coupling to the object. The acoustic energy can be of a single frequency, or it can be distributed over a set of random frequencies (i.e. white noise), or it can be in the form of a signal which is "swept" through a range of frequencies. In the latter case, the results can be stored in a video buffer (150) which records the maximum signal obtained, for each pixel, while the signal is swept through the frequency range. Different defects (125) in the object may resonate at varying frequencies within the given range. By exciting the object at each frequency within the range, and superimposing the maximum signals obtained for each pixel, the resulting image is likely to show all the locations on the object which may be defective. The preferred form of interferometry is electronic shearography, which is particularly suitable for recording interference patterns in a video buffer. The present invention is especially useful in detecting delaminations in bonded articles, and is particularly advantageous in testing large objects.
