Inventor: BRUCHHAUS RAINER DR
IPC: C04B35/453
Filed: 1990-09-13
Abstract: A ceramic mixt. is formed which contains at least ZnO, additives and an organic binder and compressed into the required cylindrical shape, the binder is removed by firing, a soln. of SbCl3 in water-free ethanol, pref. 5-10 wt.%, is applied to the cylindrical surface, if required this application is repeated several times, the part is sintered and electrodes are formed on the end surfaces.

Inventor: WEBER FRITZ
IPC: G05B19/042
Filed: 1992-06-12
Abstract: In order to attain a virtual reduction in the transmission time in real-time data exchange between computer and/or control systems, a prognostic is produced as a simulated image throughout the transmission time of the real-time data image MEM of the operating station C1 to be altered without loading the communication COM and the alteration is made in the simulated image at the same time as the input, while the background information is taken to the target system C2 and immediately returned as a new real-time data image. To accelerate the response, the corresponding addresses of the real-time data image may be used for the storage addresses of the simulated image. In addition, transmission and reception information may be taken via the same path and also to identical storage addresses in the receiving control system. To relieve the communication, a multiplexer program may be included in the transmission path and the data also taken via a decoder DEC and encoder ENC program for data conversion or compression, a multiple decoder/encoder program with input/output interfaces I/O for several levels providing further relief.
