Patent DE-4335938-A1 (DE)
Inventor: BREUER BERT PROF DR ING
IPC: B60R16/02
Filed: 1993-10-21
Abstract: To permit early detection of an impending danger of aquaplaning, deformation of profile elements (1) of the vehicle tyre (2) is detected in a circumferential direction (5) during passage through the tyre contact area. The gradient of the signal curve is ascertained approximately in the middle of the positive pulse of the signal curve determined in this way. When this gradient falls below a predetermined threshold, a signal is emitted which indicates that there is a danger of aquaplaning. Instead of this, a characteristic value may be determined in dependence on the number of local maxima in the signal curve and compared with a threshold value. <IMAGE>
Patent DE-4339320-A1 (DE)
Inventor: LINHARD ANDREAS DIPL ING
IPC: C25F3/02
Filed: 1993-11-18
Abstract: In a process of etching metal eg. copper using an ammonical etching agent and electrolytically regenerating the used agent with simultaneous recovery of dissolved metal prior to re-use, the nitrate content of the agent generated during the electrolysis is allowed to build up to an optimum of eg. 50 - 200 g/l. eg. by the addition of a reducing agent such as formaldehyde before electrolytic regeneration. This optimum nitrate content brings about a considerable acceleration of etching speed and adding reducing agents has the added advantage that for example in the electrolysis cell the conversion from copper II to copper I is favoured.

Patent DE-4416801-A1 (DE)
Title: Method and device for pattern recognition
Inventor: TANAKA KEN-ICHI
IPC: G01N21/93
Filed: 1994-05-11
Abstract: A description is given of a device and a method for pattern recognition, in which a set is generated which contains a basic pattern vector at a base location and other basic pattern vectors of patterns offset with respect to the basic pattern at the base location. A subspace is then generated, which is covered by basic pattern vectors contained in the set. A test pattern vector of a semiconductor wafer to be investigated is projected onto the subspace and the similarity between the basic pattern vectors and the test pattern vector is measured. In addition, an image can be used after it has been filtered in a normalisation filter. Furthermore, the sensitivity of the pattern recognition can be varied by changing the dimension of the pattern vectors. In addition, for objects which are expressed by numerical values and cannot be compared directly with each other, the data for the objects can be converted into images and a set of basic pattern vectors can then be calculated.
