Abstract: A switched reluctance motor includes a rotor mounted for rotation about a rotor shaft axis and a stator surrounding the rotor and having at least three electrically independent stator phases.  The motor includes an electronic circuit for for selectively energizing the phases in succession with a run current to generate a torque on the rotor and thereby rotate the rotor. The circuit includes switch operating means for selectively operating switches connecting an energy source to the phases.  The circuit also includes current sensing means for sensing the amount of current in each of the phases, and timing means for determining the amount of time for the current in each phase to reach a predetermined current level threshold. The circuit also includes pulse means for periodically selectively operating the switch operating means for a limited time to energize the unenergized phases with a seek current without substantially generating torque on the rotor, and comparing means for comparing the amount of time that current in each of the unenergized phases took to reach the predetermined current level threshold. The circuit also includes run means connected to the comparing means and the switch operating means for switching on a selected one of the switches to rotate the rotor.

Abstract: Des vibrations s'appliquant à un tissu vivant dur, tel que des os, des dents, etc., proviennent d'un élément magnétostrictif (20) situé dans un champ magnétique variable, de façon à créer des variations dimensionnelles dans l'élément magnétostrictif (20). Dans un vibrateur audiodontique destiné aux handicapés auditifs, une tige magnétostrictive (20) est située dans le noyau creux d'une bobine électromagnétique (17) à travers laquelle passe du courant en réaction à des signaux acoustiques. Le champ électromagnétique obtenu dans le noyau passe à travers la tige magnétostrictive (20), ce qui provoque de petites variations dimensionnelles dans la tige (20) correspondant à des variations d'amplitude du champ. Un actuateur (31) en contact avec la tige s'étend à partir du boîtier et transmet les variations dimensionnelles en tant que vibrations à basse amplitude au tissu dur par l'intermédiaire d'un support (41) monté sur une dent (40) au moyen d'un ciment adhésif à base de résine. Le support (41) possède un canal de réception (43) profilé afin de recevoir coulissante et amovible l'extrémité distale (37) de l'actuateur (31) en relation de frottement étroite.

Abstract: A method of seaming a circular cover panel (1) provided with a turnable pull  ring (2) onto the body of a can. The cover panel comprises a circumferential  score line (5) as close as possible to the rim portion (6) of said panel. Th e pull ring (2) on the cover panel used is mounted in a non-radial position on  said cover panel (1) with the result that a clearance (a) is provided  between the rim portion (6) of the cover panel and the nose (3) of the pull ring, and a clearance (b) is provided between the rim portion (6) of the cover panel and the handle part (2) of the pull ring. As a result, a closing chuck can be inserted in these clearances (a, b) durin g the seaming of the cover panel. In this manner the seaming operation is very  simple and very rational because it is not necessary to use a particular closing chuck, and because the cover panel need not be angularly positioned on the seaming machine before the closing chuck and the cover panel are moved towards each other.

Title: Dual functioning seal for rock bits
Inventor: CAWTHORNE CHRIS E
IPC: F16J15/32
Filed: 1997-10-07
Granted: 2004-01-13
Abstract: Dual functioning seals for use in forming a lubricant seal in a rotary rock bit comprise an annular elastomeric seal body having a dynamic seal surface for sealing against a dynamic surface and a static seal surface for sealing against a static surface.  The seal body has an asymmetric axial cross-sectional geometry the dynamic seal surface having a greater radius of curvature than that of the static seal surface.   The dynamic and static seal surfaces are formed from different elastomeric materials, and the dynamic seal surface is formed from an elastomeric material that is harder and more wear resistant than the elastomeric material used to form the static seal surface.  A rotary rock bit seal constructed in this manner is well adapted to accommodate the different operating conditions and sealing requirements that exist both at the dynamic and static surfaces of the seal to ensure optimal seal performance and, thereby enhance the service life of the rock bit.

Abstract: A method for determining the reliability of time processed seismic reflection data near a significant velocity differential overhang includes displaying the seismic reflection data as a seismic section showing impedance differential interfaces (12). The position of an edge of the velocity differential overhang is located and acoustic velocity values are interpreted (14). A set of curves representing boundaries of reliability for predetermined dip values is determined (16). The set of curves representing boundaries of reliability may be displayed (18). The display of the set of curves representing boundaries of reliability may be overlaid (20) on the seismic section representing the seismic reflection data. The dip angle for an interface of interest is approximated (22). The interface of interest is compared (24) with the curve representing boundaries of reliability for the dip angle for the interface of interest to determine the extent of reliability of the data used to map the end of the interface under the overhang.

Abstract: A dielectric resonator device has a dielectric member.          Electrodes are respectively formed on the upper and lower surfaces of the dielectric member.  The dielectric resonator device resonates at a mode having electric field components in a direction perpendicular to the upper and lower surface of the dielectric member.  The electrodes formed on the dielectric member are each formed of a thin film multi layered electrode produced by alternately laminating thin film electrode layers and thin film dielectric layers.  Each thin film dielectric layer which is sandwiched between the thin film multi layered electrode layers serves as a dielectric resonator.          Accordingly, the thin film multi layered electrode acts as a laminated structure of a plurality of dielectric resonators.  Thus, a current distributes over the plurality of thin film electrode layers, thereby alleviating the current concentration on the surface of the dielectric member.  As a consequence, conduction losses of the overall resonator unit are reduced.

Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N19/89
Filed: 1994-03-25
Granted: 2004-05-18
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.
