Abstract: The invention relates to a device for recognizing the impact site (29, 37) of a charge carrier beam on a target. This device has two position-sensitive detectors (22, 23) above the target which have a given distance from each other and from the target and on which via imaging systems (24, 25) the impact site (29, 37) of the charge carrier beam is imaged by means of X-rays. The output signals of these detectors (22, 23) are placed on a special evaluation device which determines all three spatial coordinates of the impact site (29, 37) of the charge carrier beam.

Abstract: The invention relates to a device (20) for a unipolarly operated component (9) capable of storing energy. This device (20) can be applied, for example, in an asymmetrical half bridge circuit (1). It compensates the dc magnetic flux which originates due to the unipolar operation and, hence permits making relatively small in size the component (9) capable of storing energy. Using a current converter (25, 32) with suitable winding ratio as an automatic and load-dependent compensation device, moreover, permits very flexible adaptation to load changes. Such adaptation is, in particular, required when very high pulsating current occurs on the primary side with simultaneous secondary no-load operation.

Abstract: A device and a method for the control and monitoring of a deflectable electron beam is provided for the working of metal wherein the electron beam is not permitted to go beyond an allowed working area. With this device with the aid of a Teach-In method the limits are entered into a computer. The computer generates an image of the areas allowed for the electron beam in a particular area of a special memory. This memory is so organized that the addresses of the point of the particular areas correspond to the digitized coordinates of the point of impingement of the electron beam. The characterization of the allowed and forbidden target points of the electron beam takes place through placing or deleting respectively the assigned bits in the special memories.

Abstract: A reaction gas is admitted in the immediate vicinity of a target on the cathode and a plasma is generated between the target and a substrate to be coated. The intensity of the spectral line of a target material is measured, and is used to provide a first signal with a relatively short time constant to a controller via a first control circuit. A property of the finished coating is sensed after the substrate leaves the coating zone, and is used to provide a second signal with a relatively long time constant to the controller via a second control circuit. The controller uses the combined signals to regulate the admission of the reaction gas so that a pre-established property of the finished coating is kept substantially constant.

Abstract: The invention concerns apparatus for detecting the position of incidence (2) of a beam (1) of charge carriers on a target (3) wherein X-rays (4) starting from the position of incidence (2) are detected by detector (7) connected to an analyzing circuit (9) An imaging system (5, 50; 10, 11, 12) is provided which can cover all the positions (P.sub.1 . . . P.sub.8) that the positions of incidence (2) can take up and projects them on the sensing surface of a position-sensitive detector (7), wherein the projected coordinates (x', y') are directly proportional to the coordinates (x, y) of the position of incidence (2). In addition, a filter (6) highly transparent to the X-ray radiation range emitted from the position of incidence (2) is arranged between the target surface (3) and the position-sensitive sensor (7). The position-sensitive detector (7) emits electric signals which depend from the coordinates (x, y) of the position of incidence (FIG. 1).

Abstract: In automatic melting crucible tipping it is important that, starting from a certain angular position, the melting crucible (1) is tipped according to a predetermined model until emptying is complete. This model can be obtained, for example, by the so-called teach-in process and can be stored in an analog or digital memory (89). In order to prevent abrupt movement of the crucible (1) when the molten material touches the pouring lip (3) of the crucible (1) when the pour-lip angle has been reached, according to the invention a correction arrangement (108, 109, 37) is provided which enables the tipping process to proceed continuously and without abrupt movements even in the case of different pour-lip angles.

Abstract: Apparatus for controlling the distance of a melting electrode from the surface of melted material in a vacuum arc furnace which uses short circuits caused by the droplets between the melting electrode and the surface of the melted material as a control criterion. The short circuits occurring within a given period of time--the so-called droplet rate--are determined and supplied to an averager which is connected with a controller that controls an electric driving mechanism for the melting electrode. According to the invention, the controller is responsive to a signal representing the difference between the reciprocal value of the droplet rate signal formed by the averager and a desired time, this desired time being equal to the desired average time between two consecutive droplet short circuits.
