    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: In an apparatus for coating substrates, having sputtering cathodes (4, 5) disposed in a vacuum chamber (1), sputtering targets (6, 7), a medium-frequency generator (9) connected to the cathodes (4, 5), and a system (16) for detecting and suppressing undesired arcing, a cycle of the medium-frequency signal of the medium-frequency generator (9) is divided into a plurality of time segments, the electrical values of current and voltage for a predetermined time segment being determined so as to form a measured value signal and being entered into a ground-free meter island (16). The meter island (16) is tied as a remote station into a circular network (9, 16, 17, 18, 19, 11) whose master station is situated in the control unit (11) present in the generator (9). The blocking of the generator (9) when an arc occurs takes place through a line (19) connecting the meter island (16) to the generator (9). The parameters of the arc surveillance and the detection of measured values are preset through the network (17, 18, 19) by means of software.
