  • Patent number: 6774460
    Abstract: The present invention relates to an impact ionisation avalanche transit time (IMPATT) diode device comprising an avalanche region and a drift region, wherein at least one narrow bandgap region, with a bandgap narrower than the bandgap in the avalanche region, is located adjacent to or within the avalanche region in order to generate within the narrow bandgap region a tunnel current which is injected into the avalanche region. This improves the predictability with which a current can be injected into the avalanche region and enables a relatively narrow pulse of current to be injected into the avalanche region in order to enable a relatively noise free avalanche multiplication. The narrow bandgap region may be located between a heavily doped contact region and the avalanche region and is preferably arranged to generate a tunnel current at the peak reverse bias applied to the diode.

  • Patent number: 6545340
    Abstract: A semiconductor device of the invention in the form of a superlattice-heterojunction bipolar transistor (SL-HBT) 10 incorporates a superlattice region 16 within an emitter mesa 21. The superlattice region 16 provides a non-linear response to a sufficiently high level of device current to counteract thermal runaway. This protects the device from damaging levels of current. The device 10 may be a radio-frequency SL-HBT with performance equivalent to that of a conventional heterojunction bipolar transistor. The invention may also be implemented as a semiconductor laser.

  • Patent number: 5611485
    Abstract: A method for dispensing a substance including the steps of housing the substance in a container in a substantially flowable state; establishing a path in proximity to the substance for movement of the substance from the container; and applying pressure to the substance within the container to force the substance from the container and along the path. An apparatus for dispensing a flowable substance including a container having an interior adapted to receive the flowable substance; an assembly adapted operably to be connected to the container and having a first passage through which the flowable substance is to be dispensed and communicating with the interior of the container through an opening; an assembly defining a second passage communicating with the interior of the container; and a mechanism for individually pressurizing the first and second passages to cause the flowable substance to be forced from the interior of the container through the opening and into the first passage to be dispensed.

  • Patent number: 5167551
    Abstract: In the sport of bodysurfing, hand fins are worn and reliably held on the surfer's hands. Each hand fin has longer outer and shorter inner rails for better stability and guidance, a keel for straight tracking through a wave, and curved channels for creating more lift and increased speed through the wave. A peripheral lip provides lift even during steering maneuvers.

  • Patent number: 4888393
    Abstract: The invention relates to a novel low profile additive (LPA) for uncured polyester resins and the resultant molding compositions. The low profile additive is the reaction product of an ethylene/alphaolefin copolymer with a carboxylic acid or anhydride, to thereby form a non-thermoplastic carboxyl modified polyolefin. The novel LPA is a remarkably effective dimensional stabilizer and has displayed the ability to achieve net expansion in a cured polyester resin molding composition.
