Patent EP-0031180-A2 (EP)
Inventor: ROBERTS JOHN STUART
IPC: H01S5/00
Filed: 1980-12-08
Abstract: A method of growing III-V alloy layers by a molecular beam epitaxy process. Difficulties have been experienced when growing doped III-V alloy layers by conventional molecular beam epitaxy processes due to the introduction of electron or hole traps which impair the electrical and optical properties of the alloy. Such III-V alloy layers are used in making microwave and opto-electronic semiconductor devices such as field effect transistors and laser diodes. 
<??>In the present invention, an epitaxial layer (48) of a doped III-V alloy is grown on a semiconductor substrate (1) by placing the substrate (1) in a vacuum chamber (3), reducing the pressure in the vacuum chamber (3) to below atmospheric pressure, maintaining the substrate (1) at a temperature inthe range from 300 to 500 DEG C, and directing a plurality of molecular beams containing the constituent elements of the doped III-V alloy and a molecular beam of lead onto the heated substrate (1). The magnitude of the lead flux is sufficient to form and maintain a presence of from 5 to 20% of a monolayer of lead on the growth surface..

Abstract: Die Erfindung betrifft einen Zerstäüber für die Vernebelung von flüssigen oder festen Stoffen, wie Medikamente, mit Hilfe eines Druckluftstromes, insbesondere zu Inhalationszwecken. Der Zerstäüber besitzt eine in einem Vernebelungsraum (10) befindliche Zerstäüberdüse (3), die an einen Druckluftkanal (2) angeschlossen ist und eine Ansaugeinrichtung zum Ansaugen des Medikamentes besitzt, wobei der Druckluftkanal neben der Düse eine außer Funktion setzbare Abblasöffnung (15) zum Entweichen der Druckluft hat, die zum Beispiel beim Einatmen des Patienten verschlossen und beim Ausatmen geöffnet werden kann. Bei vorbekannten Zerstäübern wird die durch die Abblasöffnung abgeleitete Druckluft unter zischender Geräuschentwicklung und der Gefahr der Verletzung des Bedienenden ins Freie geleitet. Um diesen Nachteil zu vermeiden, mündet bei dem erfindungsgemäßen Zerstäüber die Abblasöffnung in den Vernebelungsraum. Zweckmäßig liegt diese Abblasöffnung an derjenigen Seite des Druckluftkanales, die dem Aufnahmeraum (7) für den zu vernebelnden Stoff abgewandt ist.

Abstract: An electrical terminal (10) has a spring beam part (31) anchored to a support (30) and from which extends a contact spring portion (12) having a contact surface (16) for engaging a conductor (52) of a circuit board (50), upon a cam follower (40) being withdrawn from an abutment surface (14) of the contact spring portion (12). 
<??>The contact spring portion (12) is so formed that it is deflected by the cam follower (40) when it is applied to the abutment surface (14), before the spring beam part (31) is deflected, and so that when the cam follower (40) is withdrawn from the abutment surface (14), the contact surface (16) wipes along the conductor (52). 
<??>A plurality of the terminals (10) may be incorporated in a zero insertion force circuit board edge connector.

Abstract: Bei einem Verfahren zum Programmieren von Bewegungen und von Bearbeitungskräften bzw. -momenten eines Robotors werden von einem raumfest angeordneten oder von einem nach dem letzten Robotergelenk, aber vor dem Robotergelenksensor angebrachten Sensorgriff abgegebene Spannungen mit einer Sensormatrix multipliziert und dadurch in Kräfte/Momente umgesetzt; von einem Robotergelenksensor abgegebene Spannungen werden ebenfalls mit einer Sensormatrix multipliziert und die sich dabei ergebenden Kräfte/Momente werden in Inertialsystemwerte transformiert. Die Summe der vom Sensorgriff abgeleiteten Kräfte/Momente und der vom Robotergelenksensor abgeleiteten Kräfte/Momente werden dann im einfachsten Fall in Translations-/Rotationsgeschwindigkeiten umgesetzt, welche dann durch eine Koordinatentransformation in vom Roboter verarbeitbare Gelenkkommandos umgeformt werden.
