Abstract: ABSTRACT OF THE DISCLOSURE:         Structural assembly, more particularly for a shower partition, comprising a structural member having a guide channel provided in visible outer face.  Located in this channel is a facing decorative panel held by a resilient connecting element having lateral projections engaging in grooves formed by the side walls of the guide channel.  It is not possible with known cons-truction to ensure firm seating of the facing panel in the guide channel because of manufacturing tolerances. furthermore, existing devices are comparatively transversely high.  It is therefore proposed that the lateral projections of the connecting element be provided with resilient arcs turned towards the central plane of the connecting element and of the guide channel, these arcs holding the connecting element in the grooves under a predeterminable preload resilient force.  The facing panel and the connecting element are also formed with interlocking detent hook-shaped resilient webs that hold them firmly together.

Abstract: Abstract of the Disclosure A multiprocessor system the kind in which two or more separate processor modules are interconnected for parallel processing includes two redundant interprocessor buses dedicated exclusively to interprocessor communication.  Any processor module may send information to any other processor module by either bus.  The buses are shared in use by the processor modules on a time-sharing basis.  Use of each bus is controlled by a special bus controller.  The multiprocessor system includes an input/output system having multi-port device controllers and input/output buses connecting each device controller for access by the input/output channels of at least two different processor modules.  Each device controller includes logic which insures that only one port is selected for access at a time.  The multi-processor system includes a distributed power supply system which insures uninterrupted operation of the remainder of the multl-processor system in the event of a failure of a power supply for a part of the system.  The distributed power supply system includes a separate power supply for each processor module and two separate power supplies for each device controller.  Either one of the two power supplies provides the entire power for the device controller in the event the other power supply fails.          The distributed power supply system permits any processor module or device controller to be powered down so that on-line mainten-ance can be performed in a power-off condition while the rest of the multiprocessor system is on-line and functional.  The multiprocessor system includes a memory system in which the memory of each processor module is divided into four logical address areas -- user data, system data, user code and system code.  The memory system includes a map which translates logical addresses to physical addresses and which coacts with the multiprocessor system to bring pages from secondary memory into primary main memory as required to implement a virtual memory system.  The map also provides a protection function.  It provides inherent protection among users in a multiprogramming environment, isolates programs from data and protects system programs from the actions of user programs.  The map also provides a reference history information for each logical page as an aid to efficient memory management by the operating system.          The multiprocessor system includes in the memory of each processor module an error detection and correction system which detects all single bit and double bit errors and which corrects all single bit errors in semiconductor memory storage.

Abstract: ABSTRACT         A fiber optic energy sensor and optical demodulation system is disclosed wherein the signal energy to be sensed or detected causes an etched single mode fiber to be stretched or compressed which causes the optical path length for electromagnetic radiation traveling in the core of the optic fiber to change.  The change in optic path length modulates the electromagnetic radiation traveling in the fiber.  The optical demodulation system locates each energy sensor between the members of a pair of length limited Bragg reflectors formed inside of the optical fiber.  Each pair of reflectors as arranged, forms a Fabry-Perot type interferometer which only contains resonances for those portions of the electromagnetic spectrum in which the Bragg reflectors operate.  Since each energy sensor is located between the reflectors of a pair, then as signal energy is detected the sensor's resulting optical path length change causes the resonances of the Fabry-Perot interferometer, to shift spectrally.  The system then partially demodulates this spectral shift using a second Fabry-Perot interferometer, called the analyzer interferometer, whose resonances have a spectral separation relative to that of the interferometer containing the energy sensor so as to cause amplification of the spectral shift.  The output of the combination of the energy sensor interferometer and the analyzer interferometer shifts spectrally more than the original spectral shift by an amplification factor given by equations presented in the detailed des-cription of the invention.  The system also allows the use of more than one analyzer interferometer, each causing different amplification.  The resulting amplifications can be arranged to provide outputs each of which corresponds to a separate digit of the number expressing the original spec-tral shift thus reducing the bandwidth of the electronic detectors and time demodulator.

Abstract: HIGH SPEED MERGED CHARGE MEMORY                         ABSTRACT      A semiconductor memory  produced  in  a  unipolar technology  includes  a cell  which  has  a  diffusion storage capacitor with one overlying terminal being merged  with  a  bit/sense  line,  the  other  capacitor terminal is a diffused region and is coupled through a word transfer device to a word line injector charge source held at a fixed voltage.  To provide an organ-ized array of these cells, each bit line cell includes a  shared word  line  charge  source  held at  a  fixed voltage and formed at the surface of a semiconductor substrate.   A  diffusion  storage  capacitor  also  is formed at the surface of the semiconductor and spaced apart from the shared charge source.   Information is written into each bit line capacitor by applying a voltage of either of two different magnitudes, repre-senting 1 and 0 bits of information, to the respective bit line while  a word  selection pulse  produces  an inversion  layer  at  the  surface of  the  substrate between each bit line capacitor and its shared word line fixed voltage charge source.  At the termination of the word pulse, the fixed voltage remains stored at the capacitor node.  The capacitors having the larger voltage  applied  to  the  bit  line  terminal  of the capacitors store the greater amount of charge.  This charge can then be detected by measuring the voltage of the floating bit sense line when a word pulse again connects the fixed voltage charge source with each of its respective capacitors.
