Abstract: Verfahren zur Erzeugung eines Streifenwellenleiters (2) mit BH-Schichtstruktur, wobei aus der Schichtstruktur ein erhabener Streifen (1) herausgeätzt und dieser Streifen (1) mittels einer Abtragschmelze seitlich angelöst wird. Bei bekannten derartigen Verfahren werden die seitlichen Begrenzungsflächen (21, 22) des Streifens (1) einer Atmosphäre und/oder Chemikalien ausgesetzt. Dadurch haben diese Flächen eine verminderte Qualität, die Ursache für Alterungsmechanismen sind, die ein solcher Streifenwellenleiter (2) zeigt. Zur Erzielung seitlicher Begrenzungsflächen hoher Perfektion wird so vorgegangen, daß die seitlichen Begrenzungsflächen (21, 22) der wellenleitenden Schicht (2) des Streifenwellenleiters von einem von der Abtragschmelze gelösten Teil (5) dieser Schicht (2) abgedeckt belassen werden, und daß dieser Teil (5) mit als Wachstumsschmelze zur Erzeugung einer seitlich an die wellenleitende Schicht (2) angrenzenden Epitaxieschicht (6) verwendet wird.

Abstract: The invention relates to a device for disinfecting food containers, in particular plastic beakers for milk products, using a disinfectant, having an aerosol generator with MHz-ultrasonic transducer for producing droplets of the disinfectant and having a separator in which the droplets, which are supplied by an air stream, are charged by corona discharge and are deposited electrostatically onto the surfaces of a container, the separator consisting of a separating head, which engages in the container and has a central point electrode fed by a generator, of an outer electrode which surrounds the container, and of an auxiliary electrode on the end part of the separating head, which forms an electric field with the outer electrode. With regard to functional improvements to the separating head, a first improvement is proposed in which, after a measurable reduction or after extinguishing of the corona current, the polarity of the point electrode can be switched from negative to positive voltage, and vice versa. …<IMAGE>…

Abstract: A radar receiver for analysing received signals, particularly C.W. signals [Fig. 2(a)], and extracting timing information, in which the received signal is mixed (7) with a ramp frequency modulated signal [Fig. 2(b)], the swept frequency range being such that the mixer output passes through the passband of a frequency compression filter (15) which complements the frequency sweep to produce a regular pulse output [Fig. 2(c)]. A received pulse signal [Fig. 3(a)] can then be accommodated by ensuring that the swept mixer output still includes a portion within the filter passband (f₄ - f₃).

Abstract: Die Erfindung betrifft RC-Leitungen, die als Bauelemente für die Filtersynthese eingesetzt werden, wobei Widerstände und Kondensatoren nicht als diskrete Bauelemente nebeneinander, sondern als Dreischichtstruktur, bestehend aus zwei leitenden Polysilizium-Schichten und einer dazwischen liegenden Oxidschicht, übereinander auf einem Halbleitergrundkörper angeordnet werden. Die beiden Polysilizium-Schichten bilden zusammen mit der Oxidschicht eine verteilte Kapazität, wobei eine leitende Polysilizium-Schicht einen ohmschen Widerstand realisiert. Durch die flächenhafte Ausbildung der Polysilizium-Schichten und der Oxidschicht entstehen ohmsche Parasitäten, die die elektrischen Eigenschaften der RC-Leitung wesentlich verschlechtern. Diese ohmschen Parasitäten werden erfindungsgemäß dadurch eliminiert, daß sowohl die beiden Polysilizium-Schichten als auch die dazwischen liegende Oxidschicht leiterbahnartig strukturiert sind, in der Weise, daß die Bahnen in flächensparender Weise parallel zur Ebene des Halbleitergrundkörpers gefaltet oder gerollt sind und kongruent übereinander liegen.

Abstract: A reciprocating internal combustion engine for vehicles, in particular passenger motor vehicles, functioning on the diesel principle, is proposed which has a main combustion chamber formed in each cylinder above the piston and a secondary combustion chamber connected to said main combustion chamber by an overflow duct, the secondary combustion chamber being formed as a chamber contained in the cylinder head. In order to reduce the combustion noise in the case of chamber diesel engines of this type and to improve the starting behaviour at low ambient temperatures and reduce the engine vibration when idling, the compression ratio of the internal combustion engine is to be raised to values > 23, preferably 25 to 27, and at the same time a device which can be switched in whilst operating with low load and/or no load (idling) once a predetermined combustion engine limit temperature has been exceeded is to be provided for at least partially restricting the air taken in. In addition the ratio of the volume of the secondary chamber to the total compression volume is to be raised to values > 0.55 and the start of fuel injection shifted in the direction of delayed injection.

Abstract: An antenna switch control circuit for use in achieving antenna selection diversity in TDM RF receivers. RSSI for at least one antenna is monitored during time slots containing information not of interest. This information can then be compared with other antenna performance information to allow a selection to be made such that the receiver generally operates with the antenna receiving the strongest signal. In one embodiment, all possible antennas are monitored during a time slot containing information not of interest. In another embodiment, RSSI for the selected antenna can be monitored during the time slot of interest, such that antenna selection can again be varied should the selected antenna diminish in performance.

Abstract: The invention is an apparatus for and the method of clamping flexible items in a fixed position in relation to the measuring probe of a coordinate measuring machine. A perforated rigid plate is attached to the working surface of accordant measuring machine. One or more hollow, rigid article holders are mated to the plate by use of suitable fastening mechanisms. On the upper end of each hollow support holder for articles is a flexible suction cup. A source of vacuum is provided to the article holders which is directed through the opening of the suction cup. One or more spacers may be installed on the plate as well, to help position a part. A part to be measured is then placed on the article holders and a vacuum applied. Coding of the position of each of the perforations on the plate allows for easy set up and repeatability. The spacers are equipped at one end with a mechanism to allow attachment to the plate, and at the opposing end with a mechanism to allow mating of the spacers together, or mating of the spacers with the article holders. In this fashion, the spacers can function to change the height of the article holders in relation to the surface of the plate, and can also function to restrict the movement of the article placed on the invention. The method herein described includes the method of utilizing the features of the invention to affix an article   to accordant measuring machine with good reliability and repeatability.

The agent is nearly uniformly fed from the interior of the wet roller unit to the outside surface thereof. The agent remaining on the film stuck to the plate is removed from the film, downstream of the pressure sticking roller unit.

Abstract: A clamping device (S1) of a bicycle pedal (2) for fastening an engageable article (3) to the pedal, and a bicycle pedal employing this clamping device (ST). The clamping device comprises a clamp member (4) including an engaging hook (5) pivotable toward and away from a forward or rear end of a pedal body for engaging the engage­able article (3), and an urging member (10) for urging the hook toward the pedal body. When the engageable article is moved sideways relative to the pedal body (2), the hook (5) pivots away from the pedal body to release the engage­able article (3). The clamping device (ST) further comprises an upward pull selector (SE) for selectively allowing the hook (5) to pivot away from the pedal body (2) when the engageable article (3) is pulled upwardly relative to the pedal body (2). This selector (SE) is switchable between a position for prohibiting the engageable article (3) from being pulled upward, thereby avoiding a danger resulting from disengagement of the engageable article from the pedal body (2), and a position for allowing the engageable article (3) to be pulled upward with ease.
