Filed: 1994-03-15
Abstract: In order to check the establishment of synchronization at a node in a synchronous communication network which performs communication by sending and receiving frames formed by successively adding pointers showing header positions to a plurality of data, a comparison is made between the values of pointers added to data received from an opposing node side and the values of pointers to be added to the data sent from a home node so as to detect if the two values coincide and it is recognized that synchronization has been established between the opposing node and the home node when they do. An apparatus for performing this check includes a demultiplexer unit (1) for demultiplexing a received signal into data and pointers by the timing of the received signal and monitoring the demultiplexed pointers, a memory (2) for holding the demultiplexed data, a multiplexer unit (4) for successively reading out the held data by a clock of a clock source (3), adding pointers showing the headers of the same and multiplexing to prepare a transmission signal, and monitoring the added pointers, and a comparing unit (5) for comparing the pointers monitored by the demultiplexer unit (1) and the pointers monitored by the multiplexer unit (4), synchronization between the clock of the transmission node of the received signal and the clock of the home node being detected by coincidence in the comparison. <IMAGE>

Patent DE-4428015-A1 (DE)
Title: Surface treatment process for quartz materials
Inventor: KOTAKA HIROAKI
IPC: C03C17/22
Filed: 1994-08-08
Abstract: A quartz material is subjected to heat-contact treatment with ammonia gas at 1200 DEG C or below in the presence of a carbon-producing source with rapid and easy formation of a silicon oxynitride coating (layer) on the surface of the quartz material. The surface-treated quartz material obtained has excellent heat resistance, and detachment of the silicon oxynitride coating from the quartz material does not occur, even if the latter is subjected to repeated heating cycles. Furthermore, the heat resistance is further improved if a second surface-treatment step is carried out with application of a silicon nitride film to the silicon oxynitride coating using a CVD process or the like after the surface-treatment step with formation of a silicon oxynitride coating on the surface of the quartz material.

A côté de la possibilité de construire ces matériaux de garnissage avec des couches disposées perpendiculairement à l'axe des colonnes ou du canal, sont également indiquées des méthodes pour la fabrication de ces pièces insérées par superposition de feuilles de métal qui gardent leur forme uniquement par estampage et formage des bords.
Patent WO-8702840-A1 (WO)
Title: Interference suppression circuit
Inventor: FALK WILFRIED
IPC: H02P7/293
Filed: 1986-09-19
Abstract: Circuit for suppressing interference from electricity users, the mean electrical power of which can be modified by phase control. Simple interference suppression can be achieved by connecting the earth (17) of the electrical equipment, at least for the high frequencies, with the electrical connection (20) from which the consumer is separated during the rest time of the switch (21) which can be triggered by a console with a simple connection in series consisting of a capacitor (18) and a resistor (19) between the earth (17) and first connection (20), a low-impedance interference suppression bleed is obtained during the rest period. The circuit described is particularly suitable for interference suppression of electric motors in which the rotation speed is regulated by phase control, since until now it has been possible only at great expense to prevent the occurrence of interference in the electric motor (10, 30) during the rest period of the switch (21). It is thus not necessary to use expensive and voluminous interference suppression equipment.
