Abstract: TRUE LEAST RECENTLY USED REPLACEMENT METHOD AND APPARATUS                 ABSTRACT OF THE DISCLOSURE    An apparatus for performing LRU techniques for a 4 way set associative cache system.  A RAM stores the ways representing the least recently used (LRU), most recently used (MRU) and LRU+1.  The MRU-1 is developed by XORing the other three LRU way information values. Processor or snoop operation is determined and the way use aging information valued is based on snooping or processor operations.  For processor operations the accessed or to be accessed way is set as the MRU, while in snoop operations, the way being accessed is set as the LRU.  The aging of the remaining ways is shuffled accordingly.  This shuffling occurs each cycle but is only stored on processor cache hit, processor read cache miss and snoop hit operations.

Patent CA-2052120-A1 (CA)
Title: Bending shaft draft force sensor
Inventor: VANGERPEN HARLAN W
IPC: A01B63/112
Filed: 1991-09-24
Abstract: A draft force sensor includes a bendable shaft which extends laterally though a pair of spaced apart supports. Draft links are coupled to the ends of the shaft.  A curved flexible strap is positioned between the supports and has its ends coupled to the shaft by adjustable support brackets.  In a no-load condition the strap is concave in a direction facing the shaft.  A displacement transducer, such as a rectilinear potentiometer, linear variable transformer or other electrical device which is sensitive to displacement, is mounted between the shaft and the central portion of the strap.  The displacement transducer senses the change of distance from the shaft to the "arch" of the strap and generates an electrical signal indicative of the forces on the shaft.  The load from the draft links is applied to the ends of the shaft, causing it to bend and causing the strap to flex in the opposite direction.  Thus, the shaft and strap act as a mechanical amplifier.  The resulting draft sensor can sense both tension and compression.

Title: Apparatus and technique for installing an elongated rod in an earth formation

IPC: E21B7/20
Filed: 1991-10-30
Abstract: ABSTRACT APPARATUS AND TECHNIQUE FOR INSTALLING AN ELONGATED ROD IN A EARTH FORMATION     A tubular casing 2 is installed in a tunnel 82 in the earth  and the  rod  14,  49  is advanced telescopically through the bore of the casing until a portion 49 of the rod is projected into the tunnel ahead of the casing, whereupon a pair of harpoon-like detents 138 anchor that portion of the rod to the wall of the tunnel so that the casing can be retracted in the opposite direction to remove it from around the remainder of the rod.  When the distal end of the casing requires a cap 16 because the earth is unstable,  pressurized fluid is applied to a piston-like insert 18 in the bore of the casing, to eject the cap and then the insert itself, before the rod is projected into the tunnel.   Moreover, when the cap is equipped with a tunneling tool 74 and the casing is used to excavate its own tunnel, the fluid is ejected into the excavation through openings 120 and 80 in the insert and the cap, respectively, to assist the casing in excavating the tunnel: and when the casing is installed, the rod is used as a stopper 136 in the opening 120 of the insert, to plug it while the fluid ejects the insert.  Then, the rod is projected into the tunnel ahead of the casing.

IPC: A61B5/05
Filed: 1991-12-18
Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus measures dielectric properties over a broad range of frequencies.  The functions of various conductivity and dielectric constant measuring devices are combined in a single tool.  A measuring tool includes novel transmitting and receiving antennas.  Electromagnetic energy flows to a transmitting antenna.  A stripline adapter permits transmission to a stripline having a metallic central strip.  A strip face is bent at approximately right angles, and has a length that is compatible with the desired frequency coverage.  A ground plane extends from the stripline adapter to the right angle bend, and a void exists between the center strip and the ground plane.  A dielectric is positioned to nearly fill the void.  The antennas are positioned so that the strip face lies flush with the tool face, to permit electromagnetic energy to be transmitted into and out of the material to be analyzed.  An enclosure comprised of four metallic walls surrounds the stripline, and is in electrical contact with the ground plane and the stripline adapter.  The invention permits an analysis of the fluids in mammal tissue, and can be used in cancer therapy by hyperthermia.

Title: Carrier recovery control with sequential fec sync detection and frame sync detection
Inventor: NAWATA HIZURU
IPC: H04L27/00
Filed: 1992-03-19
Abstract: At the transmit end of a communications system, a convolutional code of a multiplex of an information-bearing signal and a unique word is modulated upon a transmitted carrier.  At the receive end, the transmitted carrier is demodulated with a local carrier to detect the convolutional code. The error rate of a decoded version of the convolutional code is determined, and an out-of-FEC-sync signal is produced when the error rate is higher than a threshold value.  Unique words are detected from the decoded signal and counted during a prescribed time interval to produce an out-of-frame-sync signal when the count falls below a threshold.  The frequency of the local carrier is swept in the presence of the out-of-FEC-sync signal.  When this signal ceases to exist, a timeout period is set, and the local carrier frequency is swept again when the timeout period expires during the presence of the out-of-frame-sync signal.

Abstract: ABSTRACT OF THE DISCLOSURE    This invention provides a simple immunoassay system and a measuring kit for use in the measurement of anti-EBNA antibodies, in which recombinant type EBNA proteins are used.          The anti-EBNA antibody measuring kit is useful for the individual measurement of anti-EBNA-1 antibodies, anti-EBNA-2 antibodies, anti-EBNA-3 antibodies, anti-EBNA-4 antibodies, anti-EBNA-5 antibodies and anti-EBNA-6 antibodies.    Particularly, this invention provides a method for the measurement of anti-EBNA antibodies which comprises the steps of allowing anti-EBNA antibodies in a test sample to react with a recombinant type EBNA fusion protein immobilized on a support through an anti-.beta.-galactosidase antibody, allowing the anti-EBNA antibodies to react with an enzyme-conjugated anti-EBNA antibody and measuring a signal (enzyme activity) generated from the conjugated enzyme contained in an immune complex formed by the above steps.    Also particularly, this invention provides an anti-EBNA antibody measuring kit in which an anti-.beta.-galactosidase antibody and a recombinant type EBNA fusion protein are immobilized on a support through binding of the anti-.beta.-galactosidase antibody to the support and binding of the recombinant type EBNA fusion protein to the anti-.beta.-galactosidase antibody.
