Abstract: METHOD AND APPARATUS FOR CONTINUOUSLY CONTROLLING OF THE CLEANING OF SUEDE AND LEATHER                    GARMENTS     ABSTRACT OF THE DISCLOSURE      A method and apparatus for continuously controlling of the cleaning of suede and leather garments comprising a plurality of tanks each containing a slightly different cleaning fluid.  Each of the tanks is preferably continu-ously filtered for soluble impurities and is selectively communicable to a washing device into which is introduced the garments.  An additional amount of cleaning fluid is added to the wash device approximately equal in weight to the weight of the garments to be washed.  A further additional amount of cleaning fluid is added which is approximately proportional to the weight of the garments being washed.  After washing  the remaining liquid is returned to the original tank.  In this manner the tank will be refilled to the original level and will over-flow through an overflow aperture in an amount approximately equal to the further added cleaning liquid.  The overflowed gleaning liquid will then be gathered in a sump tank and be pumped to a holding tank and subsequently be distilled to remove pure solvent therefrom.  This solvent will pass through a reclaiming line to a position where it may be mixed with cleaning additives in the proper amount in order to match one of the cleaning liquids within one of the plurality of tanks.  This new mixture will new be added to the wash cylinder in an amount equal to or proportional to the weight: of the garments therein and as such the cycle will be completed.   In this fashion, a method and apparatus is disclosed for continuously maintaining the desired condition of the cleaning liquids when washing leather and suede garments.

Abstract: SEMICONDUCTOR DEVICES CONTROLLED BY DEPLETION REGIONS       ABSTRACT OF THE DISCLOSURE    A field effect semiconductor device and method of controlling the device by merged depletion regions are provided.  The device includes, in combination, first and second spaced apart PN junctions.  Deple-tion regions associated with the junctions have boundaries displaced from their respective junctions as a function of the doping concentration on either side of the junctions.  The junctions are spaced apart by a distance which allows overlap of the depletion regions positioned therebetween.  By applying a reverse bias to one of the PN junctions the conductivity on the side of the second PN junction remote from the first PN junction can be varied through the effect of merged depletion regions.  This provides in a field effect transistor device a channel and gate of the same conductivity type material.  Rathar than varying the reverse bias across a gate-channel junction to control current through the channel, as is conventionally done, with the present invention it is possible to apply the reverse bias to the remote junction and with the overlapped depletion regions cause changes to the depletion region in the channel which varies the conductivity of the channel and controls current therethrough.

Abstract: CONSUMABLE AMORPHOUS OR POLYSILICON EMITTER PROCESS             Abstract The process employs ion implantation for precise dopant control.  The implantation is performed into a thin layer of amorphous silicon covering the emitter and collector opening.  The implantation energy is chosen so that the damage is confined to the amor-phous layer.   Since the deposited silicon layer is to be removed by subsequent processing, its thickness must be carefully controlled.  The layer is prefer-ably deposited by a sputtering technique which allows the necessary uniformity and reproducibility of the layer thickness.  Furthermore, the sputtering process with its energetic ions provides a reproducible quality interface which is of critical importance for a diffusion source.  With such a source, the diffu-sion into the single crystal silicon extends about the same distance in the horizontal as the vertical direction.  This provides the greatest possible horizontal displacement of the junction under the passivating silicon dioxide layer.  The depths of the n-type region is thinned to the single crystal sur-face by consuming the polysilicon partly through oxidation and partly through conversion to platinum silicide.  The platinum silicide silicon interface provides a high surface recombination velocity in order to deplete the density of holes injected into the emitter.  The low hole density in the emitter region has a direct benefit of decreasing the switch-ing delay due to hole storage in the emitter, and hence higher device performance.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is disclosed herein for providing faster memory access for a CPU by utilizing a least recently used scheme for selecting a storage location in which to store data retrieved from main memory upon a cache miss. A duplicate directory arrangement is also disclosed for selective clearing of the cache in multiprocessor systems where data in a cache becomes obsolete by virtue of a change made to the corresponding data in main memory by another processor. The advantage of higher overall speed for CPU operations is achieved because of the higher hit ratio provided by the disclosed arrangement. In the preferred embodiment, the cache utilizes: a cache store for storing data; primary and duplicate directories for identifying the data stored in the cache; a full/empty array to mark the status of the storage locations; a least recently used array to indicate where incoming data should be stored; and a control means to orchestrate all these elements.

Abstract: ABSTRACT         A shaft seal assembly with open mode capabilities has markedly simplified construction.  A shiftable ring on the shaft is axially biased against a complemental, stationary shoulder circumscribing the shaft to form a pair of radially spaced annular seals concentric to the shaft.          A fluid pressure port on the shoulder intermediate the seals permits selective shifting of the ring away from the shoulder to open the annular seals and place the seal assembly in the open mode wherein the shaft may be rotated without wearing the seals.  In preferred forms, the seal assembly is provided with a vent between it and the shaft bearing to relieve pressure against the bearing when the seal assembly is shifted to the open mode, and also to serve as a leak indicator.

Abstract: Abstract A data processing system in which the bits of each stored word in a memory thereof are refreshed periodically.  At substantially the same time the refresh operation with respect to each word occurs, an error detection operation also occurs and, if an error is detected in a word that is being refreshed, the error is then corrected and the corrected word is written back into the memory.  Thus, errors are continuously being checked with no more use of machine time than is required for the refresh operation.  Error correction, when necessary, then takes place at a fixed frequency, a limit thereby being placed on the error correction process.  If errors in a word are detected when the word is requested for access by a requestor, the error is corrected before the word is supplied to the requestor but the corrected word is not written back into memory at that time, the word in memory being again detected and corrected at its next refresh operation.

Abstract: TITLE OF THE INVENTION     "A heating process and its apparatus in reducing air pressure within a chamber at a balanced level"     ABSTRACT OF THE DISCLOSURE     This invention relates to a heating process and its apparatus in reducing air pressure within a chamber at a balanced level.  The air within the sealed chamber is suctioned forcibly and discharged thereoutside by rotation of rotary means installed to the chamber.          Then, the air pressure therewithin gets reduced at a balanced level.  Meanwhile, an air friction heat is generated by a continuous rotation of the rotary means, thereby the chamber inside being heated by the air friction heat.  Any wet articles that are incorporated in the chamber may be dried effectively, and energy consumption for heating and drying may be saved greatly.          Further, since a high temperature heated air is filled fully within the chamber, the chamber itself may be used as a heat source.
