  • Patent number: 4959961
    Abstract: The invention concerns a supercharged internal combustion engine in which two inlet ducts, which can be closed by inlet valves and whose flows are separated from one another, and two exhaust ducts which can be closed by exhaust valves enter the combustion space of a cylinder, one inlet duct and one exhaust duct being associated with one exhaust gas turbocharger. In order to achieve both a rapid build-up of supercharge pressure in the case of positive load changes and also an optimum homogenization of the mixture in the combustion space, the two exhaust ducts are also arranged so that their flows are separated and the inlet and exhaust side connected to the same exhaust gas turbocharger can be closed by one shut-off element each.

  • Patent number: 4959326
    Abstract: A method for forming a T-gate for a MESFET device comprises a double exposure, double develop process. In a first exposure employing lithography a layer of PMMA is applied first to a substrate and spun to a desired thickness and then baked for a predetermined period. The gate pattern was aligned to the ohmic level and either E-beam written or exposed to deep UV radiation through a quartz mask. The wafer as treated was then spray developed using a mixture of MIBK and alcohol. After coating with a Novolak resist, the same gate mask was either realigned to the Ohmic level and exposed to mid-range UV radiation in the 400 nm range or alternatively E-beam written with a modified gate pattern to eliminate the T at the gate pad. The wafer was then spray developed again, this time using LSI developer. The second photo was overexposed in order to form a large opening through the top of the T while the first photo was underexposed to make the stem of the T as narrow as possible.

  • Patent number: 4959747
    Abstract: This invention concerns a circuit arrangement for current limiting for a.c. machines with phase gating control by solid-state devices, aimed at achieving a smooth start by arresting the steady decrease in the ignition angles upon the attainment of a predetermined limiting current value. For use with single-phase measurement of the load current, a circuit is provided for measuring the instantaneous value of the magnitude of the load current, such as a threshold-value detector, which is actuated by a single-phase full-wave rectified load current. The output of this threshold-value detector is applied to a monostable digital device.

    Abstract: A rod shaped or tubular housing for a sensor includes an interior space provided with upper and lower compensating openings and within which an ultrasound measured distance device. Below the ultrasound measured distance device, the interior is connected to the lower compensating opening through a narrow channel proceeding in an axial direction of the housing. The housing is formed of two half shells of plastic joined to one another whose wall parts engage into one another to form the narrow channel. The ultrasound transducers and the electrical leads are embedded into the half shells. A second ultrasound measured distance device which is in direct communication with the surrounding space may be provided above the interior space. The ultrasound transducer of the measured distance device is excited to transmit in a pulsed fashion.
