A diffusion-soldered joint and a method for making diffusion-soldered joints includes a particularly actively diffusing, low-melting-point intermediate layer, applied in the molten state, introduced in the form of a solder carrier between at least two joint components. The solder carrier includes a metal foil that is equipped on both sides with solder layers, wherein the solder layers may include multiple layers.

Diffusion-soldered joint and method for making diffusion-soldered joints

Multiple contacts are provided in an electrical contacting arrangement of a sensor element, and the sensor element has a connection-side section with contact points, or contact pads, which are each integrally bonded to a corresponding contact. Each of the multiple contacts, at least on the section in contact with the contact point on the sensor element, has a layer by which the integral bond is formed between the contact and the contact point on the sensor element. The contacts are joined to the corresponding contact points on the sensor element by diffusion soldering or diffusion welding. Each contact has a curved intermediate section which compensates for thermal and/or mechanical expansion and movements.

The rectifier arrangement, preferably for a three-phase generator for a motor vehicle, has at least one power diode of positive polarity and at least one power diode of negative polarity assigned to respective half waves of each phase of the three-phase current and a cooling arrangement for the power diodes, the power diodes of like polarity being arranged on respective heat sinks in an electrically and thermally conductive fashion, and the heat sinks being sandwiched together with at least one electrically insulating part (32) which contains the electrical conductors between the diodes and the three-phase winding. The electrically conductive connections of the power diodes (12, 14) of positive and negative polarity to the phases (U, V, W) of the three-phase generator extend within the electrically insulating part (32) so that electrical contact is made with the power diodes (12, 14) of positive and negative polarities in respective cavities (40, 44) in the insulating part (32) via in each case one spring element. A punched grid (34) for each of the phases (U, V, W) extends in the cavities and includes conductor tracks (50) and spring elements (48, 49) for making electrical contact between pairs of power diodes of opposite polarity and each phase.

The invention provides a hard solder alloy for bonding oxide ceramics to each other or to metal, particularly to alloy steels. The hard solder alloy comprises 65-80% copper, 15-35% titanium, 0.5-5% aluminum and 0.5-5% vanadium. The invention also provides a method of bonding the surfaces utilizing said hard solder alloy as the soldering alloy. The invention further provides a preferred method in which the said hard solder alloy is provided in the form of two components, namely copper and the alloy TiAl.sub.6 V.sub.4.

A device for injecting fuel in combustion chambers, especially for self-igniting internal combustion engines, is proposed, in which a fuel injection nozzle, by aspirating air through an air guide device in the manner of a jet pump, generates a fuel spray that is surrounded by an air envelope. This air-enveloped fuel spray is directed through a heating element, the heat generation of which is distributed in such a manner over its length that a desired heating profile along the heating element is produced. The type of heating profile depends not only on the properties of the material making up the heating resistor but also on its structural makeup and its electrical bonding. A highly suitable material for the heating resistor is molybdenum silicide (MoSi.sub.2).

A hollow body, especially a pressure vessel, which includes two hollow outer parts abutting with annular end faces against each other, which define together a substantially V-shaped groove ending at its apex short of the inner surfaces of the outer parts. The outer parts are aligned with each other by an inner tubular part which extends to opposite sides of the end faces of the outer parts in close proximity with the inner surfaces of the latter. A weld seam filling the V-shaped groove connects the outer parts to each other and fusible material between the outer surface of the inner part and the inner surfaces of the outer parts join these parts to each other. The pressure vessel preferably includes also a flexible membrane having adjacent its outer edge a bead located in a groove formed in the inner part and held therein by a retaining ring.

Hollow body and method of making the same

An apparatus is disclosed for solder-coating a member provided with at least one passage having two open ends. The apparatus includes an arrangement for applying molten solder is applied to the member at least in the region of one of the open ends, and an arrangement for subsequently passing a pressure fluid through the passage prior to solidification of the molten solder so as to prevent possible blockage of the passage by the solder.
