  • Patent number: 4903886
    Abstract: A method and apparatus for fastening semiconductor components, such as power semiconductors, onto substrates is a diffusion welding method wherein the surfaces to be joined are provided with precious metal contact layers and are pressed together with at least 500 kp/cm.sup.2 at a moderate temperature of approximately 150 to 200 degrees C. Components which have a structured or shaped upper side can be joined to substrates when they are inserted in common with a member of elastically deformable material, such as silicone rubber, into a receptacle chamber that is closed by a movable die which transmits the pressing power. The deformable member completely fills out the remaining interior of the receptacle chamber when the pressing power is reached.

  • Patent number: 4905236
    Abstract: The reading times for a designational reading of information communicated via an ISDN-oriented interface are formed for a recording device and transmitted thereto with the assistance of a circuit arrangement, being formed from bit clock signals and bit group clock signals, which define the boundaries of the bit groups comprising 32 bits, that are present in an ISDN-oriented interface. The reading times present in the form of bit clock pulses inform the recording device of the times at which the information are to be read and subsequently stored. The circuit arrangement contains a shift register that is formed by a plurality of registers corresponding in number to the plurality of bits of a bit group, a reset device that is realized, for example, by an inverter and a switch, and also contains an AND gate and a plurality of switch devices whose setting determines which information are, respectively, bits of a bit group are to be read and stored.

  • Patent number: 4901709
    Abstract: A shock wave source for use in a shock wave generator in an apparatus for extracorporeal lithotripsy treatment of a patient has a shock wave tube filled with a shock wave propagating medium with one end closed by a flexible sack for coupling to the patient, and an opposite end closed by a membrane having at least a portion thereof which is electrically conductive, and a coil disposed adjacent the membrane and connected to a high voltage pulse source. When high voltage pulses are applied to the coil, an electromagnetic field is generated which rapidly repells the membrane, thereby generating a shock wave. The membrane has a flexible base covered by a number of discrete laminae of conductive material. At least some of the laminae may have respectively different mass moments of inertia and/or electrical conductivity. The shock wave source is suitable for treating calculi such as kidney stones.
