Patent EP-0660977-A1 (EP)
Inventor: MILAVEC JOHANN
IPC: H02M3/335
Filed: 1993-09-14
Abstract: Der erfindungsgemässe Synchrongleichrichter enthält eine Gleichspannungs-Stromquelle (1), deren Stromflus über die Primärwicklung (2) eines Transformators (3) von einem elektronischen Schalter (4) - von einem nicht dargestellten Oszillator gesteuert - periodisch ein- und ausgeschaltet wird und enthält ferner als geschaltete Gleichrichter zwei MOSFETs (6, 7). Falls zwei oder mehrere solcher Synchron-Gleichrichter parallel geschaltet werden, ist es erforderlich und erfindungsgemäss, dass beim Ausfall eines solchen Synchron-Gleichrichters durch Ruckspeisung von dem oder den verbleibenden die geschalteten MOSFETs (6, 7) vor Zerstörung geschützt werden. Dies wird erreicht durch Einfügen zweier weiterer MOSFETs (16, 17), deren Sources je mit den Gates der ersten MOSFETS (6, 7) und über je einen Widerstand (18, 19) mit einer Leitung (11) verbunden, welche an einem Ausgang (15) des Synchrongleichrichters liegt. Der andere Ausgang (14) ist über eine Speicherdrossel (12) mit dem einen Ende (C) der Sekundärwicklung (5) des Transformators (3) verbunden, dessen anderes Ende (D) vom Drain des zweiten MOSFETs (7) gespeist wird. Die Source des ersten MOSFETs (6) liegt zusammen mit der Anode einer Schottky-Diode (26) am einen Ausgang eines Schaltblocks (29), welcher den von der Leitung (11) über die zwei genannten Schaltelemente fliessenden Strom misst. Die Gates der zwei weiteren MOSFETs (16, 17) sind über einen Widerstand (25) auf das Ende (C) der Sekundärwicklung (5) gelegt und liegen gleichzeitig am einen Anschluss eines Kondensators (24), dessen anderer Anschluss mit der Leitung (11) verbunden ist. Der Drain des ersten weiteren MOSFETs (16) liegt über einen Widerstand (22) am Ende (D), der Drain des zweiten weiteren MOSFETs (17) über einen Widerstand (22) am Ende (C) der Sekundärwicklung (5). Zwischen den beiden Ausgängen (14, 15) des Synchrongleichrichters ist ein Speicherkondensator (13) eingeschaltet. Parallel zum Kondensator (24) ist eine Logik (30) geschaltet, die bei ausfallendem Strom über den Schaltblock (29) den Kondensator (24) kurzschliesst und entlädt. Damit sperren die ersten MOSFETs (6, 7) und der Synchrongleichrichter arbeitet über die Substratdioden der ersten MOSFETs (6, 7) im reinen Diodenbetrieb; die MOSFETs (6, 7) sind vor Zerstörung geschützt.

Abstract: System for preparing liquids from at least one solid and from at least one liquid phase. The system comprises a vessel in which the solid or solids are situated and a dry chamber which is connected to the vessel or can be connected to the vessel. The dry chamber is separated from the vessel interior by a separating means which is permeable to water vapour but is impermeable to liquids. The system is suitable for the production of liquids from moisture-sensitive solids. These solids can be stored in the vessel, since the atmospheric humidity in the interior is decreased by the desiccant. The liquid can be prepared in one and the same vessel by addition of a liquid phase, since the desiccant is separated off from the vessel interior. <IMAGE>

Abstract: The surface of an electrostatic recording sheet, which has a recording (2) layer of a liquid crystal polymer directly or indirectly on a substrate (1), is selectively charged by a head before or after heating the liquid crystal polymer to a temperature higher than the temperature of forming the liquid crystal phase of the polymer, thus enlarging the domain size of the liquid crystal phase and recording information. Information is deleted by heating the liquid crystal polymer to a temperature higher than that of forming an isotropic phase of the polymer and then cooling the polymer uniformly with no application of voltage to the head, thus reducing the domain size and deleting recorded information.

Abstract: The invention relates to bracing of the central support of a composite column having spaced-apart supports extending at least partially parallel to said central support, in particular for composite columns of a bar-like grid framework, in the case of which the invention provides a central-support holder 6 which encloses the central support 3 at least partially in a positively locking and/or frictionally locking manner and from which a plurality of web portions 7 extend radially, each of said web portions 7 exhibiting a holder 8. The holders 8 each enclose one of the supports 4 at least partially in a positively locking and/or frictionally locking manner.   An increase in stability is achieved by the central-support holder according to the invention. It is only after the composite column has been set up that the central-support holder is fitted in a predetermined or desired axial position, the axial position being fixed both in accordance with visual standpoints and taking account of static standpoints. The axial fitting location of the central-support holder can be changed subsequently. This permits adaptation both to newly arising visual/architectural requirements and to changed strength conditions. <IMAGE>

Filed: 1994-05-24
Abstract: A substrate (14), a heat slug (16) with an access cavity (30), a lid (18), and a heat sink (20) having a stem (40) are used to package a high applied power VLSI die (12). The substrate comprises a stepped housing cavity at its center, and a number of electrical contacts (24) disposed at its underside. The inactive side (42) of the high applied power VLSI die (12), the top surface and underside openings of the stepped housing cavity of the substrate (14), the heat slug (16) including its access cavity (30), the stem (40) of the heat sink, and the lid (18) are coordinated in their sizes and geometric locations in view of the applied power and the heat transfer efficiency of the heat sink. As a result, sufficient heat is directly transferred away from the high applied power VLSI die through only one layer of thermal adhesive material, thereby keeping the temperature in the stepped housing cavity of the substrate from rising above an unacceptable threshold, and yet the semiconductor package can still be assembled using industry standard unmodified wire bonding and surface mount equipment.

The second conveyor is associated with a shaping device (26) which, during advance of the strip (9), folds the strip itself until it is substantially in the shape of an upside down U, thus forming the sealing flap (32). The second conveyor (15) moves between a first upturned position around the end adjacent to the first conveyor (1), corresponding to the formation stage of said sealing flap (32), and a horizontal position, corresponding to the positioning stage of the sealing flap (32) over the mouth of the sack (31) to be closed ready for subsequent sealing.
