Patent DE-3326722-A1 (DE)
Title: Method for measuring electric potentials using backscattered charged particles
Inventor: LIESKE NORMEN DIPL PHYS
IPC: G01R31/305
Filed: 1983-07-25
Abstract: The invention relates to a method for measuring electric potentials at internal circuit nodes of integrated circuit arrangements by measuring the intensity of charged particles released at a measuring point by beams of primary particles as a function of their energy inside a specific energy range which is traversed in n equal steps. The first step is to generate a calibration spectrum at a specific potential and consisting of pairs of values Ei, ci, ci being the intensity of the backscattered particles having the energy Ei (i = 0...n). The next step is to record a test spectrum having the pairs of values Ei, mi from among the circuit nodes to be investigated which have the unknown potential, and, in conjunction with stepwise mutual displacement of the two spectra in both directions within half the recorded energy range, to determine the root mean square deviation of the measured values thus assigned to one another of the two spectra. It is preferable to use for the measurement the OKLL Auger electrons of the oxygen contained in surface oxides which are released by a primary electron beam. <IMAGE>

Patent DE-3332880-A1 (DE)
Inventor: DOBLER KLAUS DR ING
IPC: F02B3/06
Filed: 1983-09-12
Abstract: To provide an unyielding support surface for a film-type, typically thick-film resistor (10) made of pressure-responsive resistance material, an unyielding pressure-tight mass of insulating material, for example a melt of glass, ceramic, or suitable plastic, is introduced into a wall portion of a wall element (11) in which a fluid pressure medium, such as high-pressure fluid for injection to a Diesel engine, is retained. The insulating mass is, preferably, formed as a plug element, for example retained within a metal screw which, simultaneously, can form a venting screw for the fuel injection system. One or two electrical conductors (12, 13) pass through the plug element, which if a metal screw, surrounds the insulating mass, the resistance element can extend over the edge of the metal which, then, can form a ground or return connection. The surface of the plug element is either flush with the surface of the wall or, for example, forms a laterally relieved slot extending parallel to the axis of the plug, which slot may be filled with a protective pressure-transmitting compound and covering the electrical resistance element there located, so that the end surface of the screw and pressure-transmitting filler will be flush with the wall (11) confining the pressure medium.

Title: Disconnectable exhaust catalytic converter for spark-ignition engines
Inventor: GEUER ERNST
IPC: F01N3/20
Filed: 1984-01-31
Abstract: The invention relates to an exhaust catalytic converter for combustion engines, which is fitted at the end of the exhaust. If the tank has been filled with leaded petrol it is switched out of the exhaust gas flow by means of a flap. If on the other hand the tank is filled with unleaded petrol, the exhaust gas flow is directed through the catalytic converter by the same flap. This system provides a solution for a transitional period, especially for the retrofitting of passenger vehicles, while unleaded petrol is not universally available and not all engines are suitable in their design exclusively for unleaded petrol. Owing to its versatile method of fitting, this system can be fitted to virtually all standard production passenger vehicles without modification of the existing exhaust system, even by the layman. <IMAGE>

Filed: 1984-07-11
Abstract: Beschrieben ist ein Verfahren zur Herstellung einer npn-Halbleiteranordnung mit einem Titan/Wolfram-Trennmetall lediglich in den n-Kontaktfenstern. Ein Halbleiterplättchen wird zunächst dem Waschemitterverfahren unterworfen, wobei n-Kollektor- und -Emitterkontaktfenster bis zum blanken Silizium freigelegt und p-Kontaktfenster mit einer Siliziumdioxidschicht bedeckt werden. Auf die Plättchenoberfläche wird eine Titan/Wolframlegierungsschicht aufgebracht, die nach üblicher photolithographischer Technik aus den p-Kontaktbereichen herausgeätzt wird. Sodann wird auch die darunter liegende Siliziumdioxidschicht in den p-Kontaktbereichen weggeätzt, und es wird dann eine Aluminiumschicht auf die Plättchenoberfläche aufgebracht. Nach einem photolithographischen Leiterzug(herstellungs)verfahren wird das gesamte unerwünschte Aluminium weggeätzt, worauf die restlichen, nicht mit Aluminium-Signalleitungen bedeckten Bereiche der Titan/Wolframschicht weggeätzt werden. Hierbei erhält man ein Gebilde, bei dem ein Titan/Wolfram-Trennmetall zwischen die Aluminium-Signalleitungen und das Silizium in den n-Kollektor- und -Emitterkontaktfenstern, jedoch nicht in den p-Kontaktfenstern, eingefügt ist. In einer Abwandlung dieses Verfahrens wird das Trennmetall nur zwischen den Aluminium-Signalleitungen und den n-Emitterkontaktfenstern vorgesehen.

Title: Tail gate for vehicles
Inventor: WILKE HEINRICH
IPC: B60P1/44
Filed: 1984-08-01
Abstract: In a tail gate for vehicles, a liftable and tiltable coupling is achieved via four-bar linkages. Here, there is provision for an upper connecting bar and a parallel connecting bar which extends below the latter approximately as far as the centre to proceed from the vehicle. At the same time, the end region of the lower connecting bar is connected to the upper connecting bar via a link bar and bears a two-armed control lever. This control lever is connected to a lifting cylinder by means of an arm which permit vertical movement and mechanical matching to the ground of the tail gate whilst the other arm rests against the lower connecting bar. In addition, a tilting cylinder engages on the control lever as an extension of the lower connecting bar. By virtue of this design, the control lever rotates during the setting up of the tail gate with its end edge and permits matching to the ground.

Title: Pneumatic power booster, especially for brake systems for motor vehicles
Inventor: FUEGEN WILLI
IPC: B60T13/567
Filed: 1984-10-17
Abstract: A rear and a front housing section (10 and 20), are both of pot-shaped design, each with a casing (14 and 24) and a collar (16 and 26) and connected to one another to form a cylinder housing (10, 20), inside which a piston plate (30) is axially movable. The cylinder housing (10, 20) contains a diaphragm (40), which has an inner section (42) supported on the piston plate (30), an outer edge (44) clamped between the collars (16, 26) and a U-type bellows (46) arranged between inner section and outer edge and in the cylinder housing (10, 20) separates two chambers (48, 50) from one another. In a rest position the U-type bellows (46), with at least approximately equal pressure in the two chambers, extends forwards from the piston plate (30) inside the rear housing section (10). With a rise in pressure gradient from the rear to the front chamber the piston plate (30) moves forward and the U-type bellows (46) is progressively applied forwards onto the casing (24) of the front housing section (20). The front housing section (20), in an area of its casing (24) lying in front of its collar (26) to which the U-type bellows (46) can be applied, has a larger inside diameter (d24) than on the collar (26) itself. Consequently the U-type bellows (46) is inflated outwards at an early stage of actuation so that the booster acquires a large effective diameter. <IMAGE>

Patent DE-3446862-A1 (DE)
Inventor: LEUTHOLD KARL-HEINZ
IPC: B65H3/46
Filed: 1984-12-21
Abstract: A separating apparatus, to which the sheet material is transported in stacks via a stack transporting system, comprises a movable retaining means which reduces the separating gap before the stack is fed and is restored to its original width immediately before separation begins. This allows for the prevention of sheets being wedged in the separating gap, which would otherwise lead to a disturbance of the separation process. The design of a stationary retaining element having an integrated second, movable element allows for the formation of a stopping surface which protrudes beyond the stopping surface of the stationary part and is hit by the leading edges of the sheets in the stack. A toothed design of the new stopping surface allows for the leading edge of the stack of sheet material to be influenced selectively.
