Patent EP-0659963-A1 (EP)
Inventor: REINHARDT SIEGFRIED DIPL-ING
IPC: G07C9/00
Filed: 1993-12-20
Abstract: The electronic immobilising device has a key (1) on which a transmitting unit (5) and a transponder (13) are accommodated independently of one another. When a button (3) on the key (1) is activated, a code signal is transmitted to a receiver (2) in the motor vehicle by the transmitting unit (5), as a result of which the doors are locked or unlocked. In addition, this code signal serves to enable the immobiliser. If the key (1) is plugged into the steering wheel lock (10), a code signal is also transmitted by the transponder (13) to disable the immobiliser. Thus, even if either the transponder (13) or the transmitting unit (5) fail, it is ensured that the motor vehicle is available. <IMAGE>

Abstract: The converter (10) is connected to a three-phase generator (15) and is of redundant construction. It has three rectifier circuits (20, 30, 40) each having six rectifier elements (24-29; 34-39; 44-49). Said rectifier elements are connected in pairs to the lines (12-14) from the generator (15) and, forming bridges, to common outputs (122, 123; 132, 133; 142, 143). Switches (124-129; 134-139; 144-149) are allocated to the rectifier elements. Normally, in each case one other pair of switches is opened in a cyclic sequence in each rectifier circuit. The other switches are closed. Sensors for functional monitoring of the phases (R, Y, B) of the generator (15) and single-phase power-factor-correction circuits (21, 31, 41) are connected downstream of the outputs (122, 123; 132, 133; 142, 143). Monitoring and switching logic (50) switches the switches (124-129; 134-139; 144-149) on and off on the basis of the signals from the sensors. In every condition, the converter loads the three-phase generator (15) approximately sinusoidally and supplies sufficient output power even in the event of one of the phases (R, Y, B) failing. <IMAGE>

Abstract: A coupler device (2) for joining two tunnel lining segments (1), includes a first bolt part (3), a second bolt part (4), both acting as anchors, and a third part in the form of a collar (5) for fitting over opposed adjacent threaded ends of the bolts (3 and 4). Head portions (3A, 4A) of the respective bolts are part-spherical and their shanks are set in respective tapering recesses (6) in the segments (1A, 1B), thereby allowing limited angular movement of the bolts. The collar (5) is internally threaded and is screwed on one of the bolts, whilst the other bolt is pushed onto the collar, overcoming an interference fit. 
     The coupler device provides a concealed fixing once the segments have been pushed together, it provides a joint which is equivalent to a screwed connection and accommodates malalignment of the segments. The device can be designed for any given pull out of the segments.

Abstract: Hydrogels of polymerized and crosslinked macromers comprising hydrophilic oligomers having biodegradable monomeric or oligomeric extensions, which biodegradable extensions are terminated on free ends with end cap monomers or oligomers capable of polymerization and cross linking are described. The hydrophilic core itself may be degradable, thus combining the core and extension functions. Macromers are polymerized using free radical initiators under the influence of long wavelength ultraviolet light, visible light excitation or thermal energy. Biodegradation occurs at the linkages within the extension oligomers and results in fragments which are non-toxic and easily removed from the body. Preferred applications for the hydrogels include prevention of adhesion formation after surgical procedures, controlled release of drugs and other bioactive species, temporary protection or separation of tissue surfaces, adhering of sealing tissues together, and preventing the attachment of cells to tissue surfaces.

Abstract: A bonded structure comprising the physical and electrical connections between an integrated circuit element and substrate using a composite bump comprised of a single polymer body of low Young's Modulus and a conductive metal coating. When the bonded structure is formed the composite bump is deformed and the low Young's Modulus of the polymer body allows a very reliable bonded structure with very low bonding force. Due to the low Young's Modulus there is little tendency to separate the connections after the bonded structure is formed. The bond can be formed using thermocompression bonding, ultrasonic bonding, application of heat or application of light. The bond can also be formed using a non conductive adhesive between the integrated circuit element and the substrate. The bond can also be formed with a conductive adhesive coating on the composite bump. The polymer body may be covered by a conductive metal coating formed at the input/output pads of an integrated circuit element or substrate. The composite bump is formed using material deposition, lithography, and etching techniques. A layer of soldering metal can be formed on the composite bumps if this is desired for subsepuent processing. 
     It is possible to use a conductive barrier metal coating covering the polymer body and a soldering metal coating covering the conductive barrier metal coating. When the bonded structure is formed the composite bump is deformed and the low Young's Modulus of the polymer body allows a very reliable bonded structure with very low bonding force. Due to the low Young's Modulus there is little stress tending to break the solder joint after the bonded structure is formed. The bond is formed using a soldering process so that the soldering metal forms a conductive adhesive between the composite bumps and either the substrate input/output pads or the integrated circuit element input/output pads.

Abstract: A wire bonding apparatus has an image pickup unit for obtaining image data of an image frame of a square area encompassing wire bond objects including electrode pads of an IC chip and corresponding inner leads of a lead frame. The image of the square area is picked up at the bonding station where the bonding operation is executed. The image data is transmitted to an image processing unit, which detects the position of each of inner leads and electrode pads and calculating deviations of position of each of wire bond objects from corresponding design position stored in a memory unit. A control unit controls XY-table based on the deviations to align a bonding tool to each of the bonding points of the wire bond objects. In the case of lead frames, tape carriers or ceramic packages, the accuracy of wire bonding can be improved without being affected by deformation of the inner leads due to transportation, thermal deformation, thermal expansion, or vibration remaining in the image pickup unit. In addition, the amount of time required for the detecting operation can be reduced.
