Abstract: A data carrier card (1) comprising a microprocessor chip (MC) with a data input interface (DI) and a data output interface (DD) which operate contactlessly. At the microprocessor element (MC), a micromotor element (R, B) is arranged which is used as reflector (R) or for shading a lightbeam (LP, LP') which is picked up by photosensors (P1, P2) so that the position of the micromotor element (R, B) represents a sequence of output data and supplies these to the interface (DD). The circuit is fed by a solar cell (SC) with an external light source (GL) which takes input data from a modulator (MOD) and sends them to the input interface (DI). <IMAGE>

Abstract: A synchronized node control system (66), which provides an interface between user processors (72), which originate and receive messages, and a packet switching network (10) that uses a multi-level communications protocol. Clusters of user processors (72) are each associated with a node controller (78) that communicates with a gateway (82) of the switching network (10). Each node controller (78) is programmed to handle level two protocols for communicating messages between node controllers (78), and level three protocols for communicating messages between said user processors (72). Each node controller (78) is further programmed to perform processes associated with these protocols such that all node controllers (78) perform the same schedule of processes during a node control frame period. Each node controller (78) is further programmed to synchronize its internal level two and level three operations within the node controller frame period, and to synchronize its level two processes, such that an originating and a destination node controller (78) transfer a particular packet during a packet frame period.

Abstract: A local oscillating frequency synthesizer for a station of a TDMA system includes a pair of synthesizers (1, 2), one being used for generating synchronizing frequencies for monitoring communication channels comprising transmission and reception slots, and the other for generating synchronizing frequencies for monitoring the electric field level of another station, when information is read out from idle slots rather than the transmission and reception slots. Therefore, without using a high speed frequency switching synthesizer such as a direct digital synthesizer or the like changes in frequency synchronization can be achieved in a short period of time by using a selector means (3) to switch between the frequency synthesizers (1, 2) and a local oscillating portion which is low in power consumption can be obtained.

Abstract: First binary coded bits of information are read synchronously from first positions in the memory and second binary coded bits of information are read from, or written in, second positions in the memory asynchronously without affecting the reading of the first bits of information from the memory. In providing for the synchronous reading of the first bits of information, a plurality of channels are sequentially activated at a frequency such as 25 megahertz. Information from a plurality of pairs of data lines are introduced into a pair of buses at a frequency corresponding to a clock frequency of 125 megacycles. The information in the buses is sampled upon the occurrence of the first polarity in synchronizing signals derived from the clock signals and having a frequency of 62.5 megahertz and is evaluated in a first pair of output lines upon the occurrence of the second polarity in the synchronizing signals. The evaluation is accelerated upon the occurrence of the second polarity in the synchronizing signals, and the evaluated signals on the first pair of output lines are neutralized upon the occurrence of the first polarity in such synchronizing signals. Similarly, the information in the buses is sampled upon the occurrence of the second polarity in the synchronizing signals and is evaluated in a second pair of output lines upon the occurrence of the first polarity in the synchronizing signals. The evaluated signals in the first and second pairs of output lines are then processed on an exclusive basis to insure that only one of the evaluated signals can be introduced at any one time to a resultant line.

The chassis and the frame (10, 18) have mutual locating means (52-54, 56-62) such that, when the chassis (10) is inserted beneath the superstructure frame (18), the mutual fixing means (52-54, 56-62) of the chassis and the frame (10, 18) are aligned for re-engagement.

Abstract: Copper corrosiveness of compositions comprising a major amount of a base oil of which at least 50% by volume is mineral oil that has an inherent sulfur content of at least 0.2 percent by weight is reduced by adding to the oil a small amount of at least one oil-soluble neutral hydrocarbyl phosphite ester, most preferably triphenyl phosphite. The addition of phosphite can yield composition exhibiting a copper rod rating of 5 or below in the Cincinnati Milacron Thermal Stability test procedure "A", even though in the absence of the addition of phosphite, the composition fails the test. The unpredictability of the invention is shown by the fact that not all high sulfur oils respond to the treatment, and no explanation for the divergence of results is presently known.

Abstract: The present invention relates to a system for measuring the amount and direction of misregistration of each layer of a panel from which multi-layer printed circuit boards are separated. The system utilizes a conductor pattern having a conductive trace positioned on each layer of the panel. Each conductive trace includes two trace portions 400 and 402, positioned in opposing relation with a plurality of conductive through-holes 412, 414, 416, 418, and 420, being positioned therebetween. Each of the trace portions 400 and 402 includes a plurality of elongate conductor portions 408 positioned incrementally varying distances from a common axis. The conductive through-holes 412, 414, 416, 418, and 420 are formed in the panel after the layers have been fabricated and joined. If the through-holes 412, 414, 416, 418 and 420 are in electrical contact with either trace portion of 400 or 402, then the amount of misregistration can be determined. Further, by determining which trace portion the through-hole is in contact with, the direction of misregistration can be determined. By adding additional trace portions, the quantity of misregistration in other directions may be determined.
