Abstract: In an information recording system, a semiconductor laser is energized in response to a drive current which is modulated in accordance with a recording signal in a recording mode so that a modulated laser beam is gener­ated from the semiconductor laser. The modulated laser beam is focused on an optical disk and is reflected from the optical disk and the reflected laser beam is detected by an photo-detector. A detection signal from the detector is compared with a predetermined threshold level which is set in accordance with the peak intensity by a binary circuit and a relationship between the recording signal and an output signal from the binary circuit is detected by a detection circuit. In an over­write mode in which the laser beam is focused on pit or pits on the optical disk, an overwrite detection signal is generated from the detection circuit and the over­write detection signal is counted by a counter circuit. When the counter circuit counts a predetermined count value, the counter circuit generates a recording inhibi­tion signal for preventing the semiconductor laser from generating the modulated laser beam.

Abstract: It includes a three-phase asynchronous motor (MAT) with two stator windings each connected respectively to controlled diodes (Ri,Si,Ti) which provide the amplitude of the wava choking controlled by speed regulators (RV1, RV2) through the modulators (M1, M2) whose intervention is determined by the signal of a speedometer dynamo (DT) through the speed regulator (RV) and the acceleration/deceleration regulator (RAD). 
So it is possible, having set a speed of the motor ranging between zero and a speed close to the synchronism, to keep this value constant reacting actively and passively to every variation of the torque of the machine. 
     Because of the great flexibility of operation, the recovery of energy during the phase of braking, the absence of the expensive part relevant to the DC generation in one case and to the AC at variable frequency in the other case, this drive shows itself really competitive with respect to the drives of the known technique both DC and AC.

Title: Duplicated-memory synchronization arrangement

Filed: 1992-07-23
Abstract: 5 n7 A shared-buffer-memory-based ATM switch module (1) is duplicated (2) and operates in active-standby mode for fault-tolerance. Following failure and repair of a module, buffer memory (12) contents of the two modules are resynchronized as follows. At the time of commencing the synchronizing, contents of the memory of the standby, repaired, module are cleared, all writes to the active module's memory also commence to be made to the standby module's memory, and track begins to be kept of overwriting of the contents of the active module's memory that existed at the time of commencing the synchronizing. This is done by a function which sets a flag (64) in a queue-length-counter monitor (60) for every active-module queue-length counter (200) that reaches a count of zero to indicate that its corresponding buffer-memory queue (100) has been emptied. When all monitor flags have been set in response to each queue-length counter having reached a count of zero, it indicates that the original contents of the active module's memory have been overwritten and the memories again have identical contents, and consequently that resynchronization of the two memories has been achieved and fault-tolerance has been re-established.

Abstract: A computer simulator system allows the user to specify prototype reaction to events in a pictorial manner using a visual object environment. A spreadsheet like State Table and a visual object collection coincide on a common graphical display. The State Table is filled in by pointing to lists of events or actions associated with the different objects. The contents of these lists are dependent on the object class. Event or action descriptions are transported into the respective cells of the State Table in the form of descriptive strings of text. This text describes the event or action, and the event source, or action destination. Entries in the State Table define the operation of the simulation and are executed directly by an interpreter or are compiled to generate a program of instructions for performing the simulation.
