Abstract: A multi-mode imaging system provides the capability of reproducing documents in a conventional COPY mode wherein a document (12) is placed on a platen (14) and scanned to create an exposed latent image on a photosensitive member (24). The system is adapted to operate in a second, print (WRITE) mode wherein an image bar (40), such as a light-emitting diode (LED) array or a liquid crystal shutter (LCS), is placed into optical alignment with a fixed optical system (18, 20, 22) including a linear lens array (22). The image bar is electrically addressed (62) to create a light output in an image-wise pattern. The image output is optically coupled into the lens array (22) which projects the image onto the photosensitive member (24). In one embodiment, the image bar is partially within the end portion (14ʹ) of a movable plate (14).

Abstract: An arrangement for driving a semiconductor device ( 1 ) has an input (12) for receiving a control signal and a control output (11) for connection to the control electrode (9) of a power semiconductor device ( 1 ) which is connected in series with a load (5) across a power supply (3,6). The arrangement includes an active turn-off device (T67) to achieve fast turn-off of the device ( 1 ). The arrangement further includes a threshold detecting means ( 29 ) which operates to turn on the semiconductor device ( 1 ) in the event of a high voltage transient on the power supply. This reduces the voltage across the semiconductor device and hence reduces power dissipation within the semiconductor during transients. The turn-off device (T67) could be damaged by high transient currents when the threshold detecting means ( 29 ) conducts, so a further threshold detecting means ( 30 ) acts to disable the turn-off means (T67) during transients. The arrangement may be integrated monolithically with an associated semiconductor output device. An intelligent power switch circuit including such an arrangement is suitable for use in a motor vehicle.

Abstract: The present invention relates to a method of testing the loading capacity of cores and is especially suitable for testing cores used in the paper industry which are made of board by glueing and reeling. 
     Hitherto it has not been possible by means of known methods to simulate the real stresses occurring in use of a core. Therefore, even the best results have been incomplete and unreliable giving only an outline of the real loading capacity of the core. 
     The method according to the invention is characterized in that the core (9) is rotated on the chuck (8) is loaded with a roll (11), the stress force of which against the surface of the core is completely adjustable. The changes in the structure of the core during the testing are registered, e.g. by an optical source of a light and sensor arrangement (15, 20), which gives a signal according to which the temporary stress force and rotational speed are registered.

Abstract: A method for maintaining the overall system availability of a multi-processor data processing system in the event of a failure at one of a plurality of independent failure points. The system includes a plurality of virtual memory type processor units, each of which includes an interactive terminal, and a main memory which is connected to a secondary storage device which is also shared by the main memory of one of the other processor units. The main memories of the two units are also interconnected to provide a shared virtual memory system. Both processor units employ the same operating system and share the same virtual address space for storing information. The interactive terminal of each processor unit is connected to the other processor unit. Failure points include the terminals, the processor units, the communication links, and the various software components that are employed by the system. System availability is maintained by managing the storage of selected information at pre-established precise points in the processing operation. Identical operating system data structures that are stored in each processor unit are updated with the results of certain identified data processing transactions which have affected information required for succeeding processing operations in manner to insure that either identical updates occur or no update occurs. The arrangement ensures that any changes that might have occurred in the information stored in the data structure prior to the end of an aborted transaction is returned to the initial state to permit the transaction to be retried whenever the path of the failure can be bypassed.
