  • Publication number: 20120061684
    Abstract: In an embodiment, a method of fabricating a transistor device comprises: providing a semiconductor topography comprising a gate conductor disposed above a semiconductor substrate between a pair of dielectric spacers; anisotropically etching exposed regions of the semiconductor substrate on opposite sides of the dielectric spacers to form recessed regions in the substrate; oxidizing exposed surfaces of the substrate in the recessed regions to form an oxide thereon; removing the oxide from bottoms of the recessed regions while retaining the oxide upon sidewalls of the recessed regions; and isotropically etching the substrate such that the recessed regions undercut the pair of dielectric spacers.

  • Publication number: 20110001957
    Abstract: A distance-measuring optoelectronic sensor for the monitoring of a working zone is provided which is located within a detection zone of the sensor and at a first distance from the sensor, wherein the sensor has a lighting unit having a light source to illuminate the working zone at least partly as well as an object detection unit by means of which unauthorized objects in the working zone can be detected. In this respect, an illumination control is designed, in a switching-on phase, first to activate the lighting unit with a lower power so that a provisional working zone at a second distance from the sensor less than the first distance is illuminated with at most a preset maximum power; to check by means of the object detection unit whether an unauthorized object intrusion is taking place into the provisional working zone; and if no unauthorized object intrusion is recognized, to activate the lighting unit at a higher power so that the working zone is illuminated with at most the preset maximum power.

  • Publication number: 20070200194
    Abstract: A current load of an electric device having a current inlet or current outlet can be protected cost-effectively and efficiently via a contact pad in the current inlet or current outlet when a first conductive material and the second conductive material are connected conductively in the contact pad such that the first conductive material and the second conductive material can form an eutectic mixture which has a fusion temperature below the fusion temperature of the individual materials and when the contact pad is additionally implemented such that the conductive connection between the first and second materials is interrupted when a fused eutectic mixture occurs.

  • Patent number: 6872310
    Abstract: In a particularly noise-free and vibration-free operating precoated filter for filtering for example cooling lubricating flowing media, a filter candle surrounding a riser channel is mounted by means of a riser tube in a separating plate in an axially moveable manner. A filter cake adhering to the outside of the filter candle is loosened in such a manner that for example a disk-shaped rotary body comprises a shoulder between the track end and the track start along its track. As soon as a head end piece connected to the riser tube and moveable in an axial manner against the force of a spring is released from the rotating track end, the stored force of the spring accelerates the filter candle, so that the filter cake adhering to the filter candles is loosened by the acceleration of the filter candle and the impact pulse when a dampening ring arranged between the filter candle and the separating plate abuts the separating plate.

  • Patent number: 6633227
    Abstract: A method of allocating a remote control to a base station. The base station delivers a search signal. The remote control receives the search signal, compares it with a reference signal, and delivers a contact signal if they match. On receiving certain contact signals in response, the base station then delivers an identification signal, and after receiving it, the remote control sends back to the base station a code signal identifying it unambiguously.

  • Patent number: 5699679
    Abstract: A cryogenic aerosol separator/classifier for separating and selectively removing particles from a stream of aerosol. The aerosol stream is produced by a cryogenic aerosol generator comprising a reservoir containing a cryogenic gas-liquid mixture at a first pressure, a delivery line coupled to the reservoir, and a nozzle. The nozzle has at least one exit opening which allows the cryogenic gas-liquid mixture to expand from the first pressure to a lower pressure and, thus, to produce cryogenic aerosol. A separator is coupled to the nozzle, such that the light particles having high mobility are removed from the stream, thereby producing a stream of cryogenic flow with particles having a controlled size to clean a contaminated surface. The apparatus is enhanced by utilizing a magnetic field and/or specially designed flow fields to fully take advantage of the enhanced mobilities of light particles.
