Patent DE-19611026-C1 (DE)
Title: Noise suppression for hearing aid with signal level dependent AGC
Inventor: GOTTSCHALK-SCHOENIG GEORG DIPL
IPC: H03F1/32
Filed: 1996-03-20
Granted: 1997-06-12
Abstract: The method involves using several different length decay time periods for the gain control, changing between decay periods and selecting each decay period according to a state change of the signal to be processed.  A longer decay period is activated when no maximum regulation of the signal gain results from the signal being processed or is necessary. In the case of a maximum regulation of the gain the decay time is changed over to a shorter period.  Detection of a state change of the signal being processed is performed at one or more tapping points in the signal path.

IPC: F16H45/02
Filed: 1997-04-09
Granted: 1998-08-06
Abstract: The bridging clutch for the hydrodynamic torque converter has fluid ducts across the clutch lining to provide a return path for the fluid from the torque converter. The ducts are produced by machining through apertures (52) of a template (50) pressed onto the clutch lining in order to provide a simple duct without loose clutch material entering the fluid circuit.

IPC: H01J37/32
Filed: 1998-10-31
Granted: 2000-03-30
Abstract: The invention relates to a device and method for coating substrates in a vacuum. A plasma is produced from a target using a laser beam and ionised particles of the plasma are precipitated on the substrate in the form of a layer. This is a known process which has been used in PVD methods for some time. The aim of the invention is to provide a means of preventing droplets and particles which could have a negative effect on the properties of the deposited layer from settling in said layer, or at least to reduce the number of such droplets and particles. To this end, an absorber electrode with a positive electric potential is used. Said absorber electrode is situated a few mm away from the bottom end of the plasma, in front of or next to said plasma and is shaped in such a way that an electric field forms around the absorber electrode. The electrical field vector should be oriented at least approximately orthogonally to the direction of movement of the ionised particles of plasma.
