Patent DE-3930832-A1 (DE)
Inventor: NISHIBORI MINEO DR
IPC: C23C14/24
Filed: 1989-09-15
Abstract: It is known to coat workpieces by means of cathode sputtering in vacuum in such a way that cathode material, zones and droplets are ejected from a cathode by gas discharge so that they are able to deposit on a workpiece. To improve coating carried out in this way, the invention provides a heating device situated in the vacuum chamber so that the workpiece is heated to a temperature in the range from 0.3 to 0.5 of the absolute melting point of the cathode material before the onset of zone generation.

Title: Controlling microphones supplied with current over cable audio cores - involves adjustment of supply voltage so that magnitude provides control information
Inventor: KERN OTMAR
IPC: H04R3/06
Filed: 1989-10-11
Abstract: The microphone control with a phantom supply adjusts the supply voltage over the audio cores such that its value represents a control information signal for the microphone. At the microphone side, the supply voltage is output coupled and its value used for deriving a control signal for the microphone. The control circuit has current supply sources (30,70) coupled to the audio cores via feed resistors (R1,2). The supply sources are adjustable such that the supply voltage value, behind the resistors, on at the audio cores (51,52), represents the control information for the microphone (10), at whose input (16,17) the voltage is decoupled and supplied to an evaluator (15).
