Granted: 1995-03-28
Abstract: An optical fiber cable closure (20) includes a cable termination assembly (22) and a cover (23) into which the termination assembly is inserted. The cable termination assembly includes two spaced end plates (34,36) through which cables (28,29) to be spliced extend. One of the end plates supports a frame (101) which supports a plurality of optical fiber splicing trays (120-120). Adjacent end portions of the trays are staggered and hinged so that some trays may be moved pivotally to expose others. Optical fibers from each incoming cable are routed in individual tubes (115-115) from an optical fiber breakout (110) mounted in the framework to selected ones of the trays. Hinge lock plates (130-130) which complete a hinge for each tray also serve to clamp the tubes incoming to each tray to prevent unintended movement.

Title: Power controller for heater load
Inventor: GRUND J EVAN
IPC: G05D22/02
Filed: 1990-03-26
Granted: 1995-02-28
Abstract: A  power  control  system  for  the  heat  lamps  for typically drying a continuous web of paper in order to provide  a  linear moisture profile locates the actuating thyristor type switch at each zone where the  heater  lamps  themselves  are  located.    Thus, computer  control  can  be  centralized  and  wiring minimized.   The parameters of minimum flicker for unity power factor and high resolution power control are achieved by utilizing the timing signals provided by the  zero crossings of the three-phase AC line voltage input and controlling either half cycles or partial half cycles for each zone.  Computing time is reduced by providing for scratch pad memory tables which can rapidly be scanned or sequenced through by a zone pointer.

Granted: 1994-07-26
Abstract: This invention relates to an axial bearing system intended for a radially mounted shaft (1) and has two hydrostatic axial bearings (4, 5) capable of axial movement relative to a surrounding bearing housing (3).  The bearing system comprises a flange (6, 7) with a pressure surface (6a, 7a) rigidly attached to the shaft (1), at an essentially right angle.  An annular chamber bearing (8, 9) has a surface (8a, 9a) facing towards the pressure surface (6a, 7a). In this there is an annular groove (8b, 9b).  The surface (8a, 9a) forms together with the pressure surface (6a, 7a) inner and outer sealing gaps to either side of the annular groove.  This, together with the pressure surface (6a, 7a), forms an annular chamber (8b,  9b)  into which hydraulic fluid is introduced under pressure.  The annular chamber bearing (8, 9) together with the bearing housing (3) forms a hydraulically pressurized chamber (15, 16) which forces the annular chamber bearing (8, 9) against the pressure surface (6a, 7a).  The two annular chamber bearings (8, 9) are forced in mutually opposing directions in this case. At least one of the flanges (6, 7)  is capable of being disassembled from the shaft (1), and in that the pressure surfaces (6a, 7a) face towards one another, that is to say the forces arising from the hydrostatic bearings and acting on the shaft (1) are directed away from one another.

Title: Speech recognition by neural network adapted to reference pattern learning
Inventor: ISO KEN-ICHI
IPC: G06F15/18
Filed: 1992-04-23
Granted: 1997-03-04
Abstract: A speech recognition method according to the present invention uses distances calculated through a variance weighting process using covariance matrixes as the local distances (prediction residuals) between the feature vectors of input syllables/sound elements and predicted vectors formed by different statuses of reference neural prediction models (NPM's) using finite status transition networks.  The category to minimize the accumulated value of these local distances along the status transitions of all the prediction models is figured out by dynamic programming, and used as the recognition output.  Learning of the reference predic-tion models used in this recognition method is accomplished by repeating said distance calculating process and the pro-cess to correct the parameters of the different statuses and the covariance matrixes of said prediction models in the direction of reducing the distance between the learning patterns whose category is known and the prediction models of the same category as this known category, and what have satisfied prescribed conditions of convergence through these calculating and correcting processes are determined as re-ference pattern models.
