    摘要: A power supply apparatus, in which the three phases of an alternating-current main are connected each through rectifier elements connected in antiparallel to the primary winding of a three-phase transformer. The secondary windings of this transformer are connected through rectifiers to a load device, such as an electron beam gun or other such device which produces short-circuits while in operation. Measuring sensors are provided on the primary AC side which, in the presence of an excess current on the primary AC side, block controlled rectifier elements. The blocking takes place very rapidly because GTO thyristors are used as rectifier elements. The decay of the magnetic energy in the transformer is achieved by the fact that the primary side of this transformer is connected in delta.

    摘要: 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.

    摘要: 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.

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).

    摘要: 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.

    摘要: 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.
