IPC: H05B3/30
Filed: 1992-11-02
Abstract: In a process for producing a heating element, a working layer with contact areas is formed by plasma-chemical deposition on a substrate. A metal surface is used as substrate. First, an insulating layer is formed on the substrate through deposition from a first mixture consisting of a precursor mix of SiH4 and Ar, which contains 96-97 % Ar, and O, the ratio between precursor mix and O being 1:2.5-5. Then, a resistive layer of alloyed amorphous silicon is formed by deposition from a second mixture consisting of a precursor mix of SiH4 and Ar, which contains 96-97 % Ar, and BF3, the ratio between the precursor mix and BF3 being 100:5-10. Both deposition processes are carried at a substrate temperature of 250-500  DEG C, a pressure of 0.2-0.5 mmHg and a specific discharge output of 0.1-0.5 W/cm<2>.

Title: PABX system with a criterion characterising a main station on the external connection line
Inventor: VANDERBUSSE ROBERT
IPC: H04M7/14
Filed: 1993-09-21
Abstract: The line criterion which characterises a main station of a PABX system and which may comprise the ringing signal applied on the exchange side is used in external traffic (exchange traffic) to implement the facility for direct dialling of a subscriber which is essentially not provided in this type of connection. For this purpose, loop closure is effected following detection of the line criterion, a free code receiver is connected and an outgoing ringing signal is emitted. The result of this is that the required subscriber telephone number entered by the external subscriber as a multifrequency code signal sequence during the ringing signal is evaluated by the code receiver. The telephone terminal concerned is called and then the connection is switched through as soon as the subscriber answers. <IMAGE>

Title: Memories monitoring method for EEPROM and battery buffered memory
Inventor: MISCHKER KARSTEN
IPC: G11C29/50
Filed: 1994-08-20
Abstract: The method involves using a memory cell, e.g. a flip-flop, outside of the memory package. The flip-flop is used as a marker with a lower overrun threshold than the memory to be monitored. During the monitoring the marker content is evaluated for fault recognition. After a voltage invasion the marker assumes a preferred value. During initial operation the marker can receive a value different from the preferred value, which is lost on a fault appearance. A fault is recognised, when the marker content is different from the initialised value. The marker may be a memory cell supplied with voltage via an ohmic resistance.
