Patent CA-2180065-A1 (CA)
Inventor: IKEDA SHIGEJI
IPC: G10L21/0208
Filed: 1996-06-27
Abstract: The object of the present invention is to provide a noise cancelling method and a noise canceller where the shortening of the convergence time and the reduction in the distortion (residual error) after the convergence can be realized.     A second adaptive filter outputs a pseudo noise signal by receiving a reference signal from a reference signal input terminal. A subtracter subtracts an output pseudo noise signal of the second adaptive filter from a receiving signal input from a speech signal input terminal, and supplies the subtraction result to the second adaptive filter as an error signal. A divisor circuit divides an output speech signal power of a power averaging circuit obtained from the output error signal of the subtracter by an output noise signal power of another power averaging circuit obtained from the output pseudo noise signal of the second adaptive filter, and outputs the result of the division as an estimated value of the signal to noise ratio (SNR). A step size output circuit operates so as to receive the output signal of a signal to noise ratio estimating circuit as an input, and output a value corresponding to the input SNR value as the step size for a first adaptive filter.

Title: Oligonucleotide n3'-p5' phosphoramidates: synthesis and compounds; hybridization and nuclease resistance properties
Inventor: GRYAZNOV SERGEI M
IPC: A61K48/00
Filed: 1995-03-20
Abstract: Modified oligonucleotides 3'-NHP(O)(O-)O-5' phosphoramidates were synthesized on a solid phase support. The phosphoramidate analogs were found to have significantly increased resistance toward phosphodiesterase digestion. Thermal dissociation experiments demonstrated that these compounds form more stable duplexes than phosphodiesters with complementary DNA and particularly RNA  strands. Further, the phosphoramidate analogs can also form stable triplexes with double-stranded DNA target, where under similar conditions parent phosphodiester compounds failed to do so.

Title: Method and apparatus for the harvesting of royal jelly
Inventor: FRASER-JONES ANTHONY PAUL
IPC: A01K47/04
Filed: 1995-06-01
Abstract: This invention relates to a method and apparatus for the harvesting of royal jelly. The method comprises the use of a first matrix of cell-like structures in an arrangement typical of normal worker bee cells which have interconnected plugs placed in the back of the matrix. A queen bee may then lay this matrix of cells with eggs. Upon the eggs turning into larvae, the plugs may be removed and the plugs are provided in interconnected sets such that each set provides plugs for each alternate cell in the first matrix of cells. These plugs may then be fitted to a second matrix of cells which provide larger, queen-like cells at a spacing of substantially the same as the alternate cells in the first matrix. The second matrix may then be placed in a queenless hive for the bees to fill the larger cells of the second matrix with royal jelly which may then be harvested.

Title: Yarn Package Transport System
Inventor: TSUZUKI KIYOHIRO
IPC: B65G47/70
Filed: 1996-04-30
Abstract: A  package  transport  system   (1)   is  provided  for transferring yarn packages from a textile machine  (2)  to a transport conveyor (4).  Textile machine (2), which is either an open end spinning machine or a winding machine, has conveyor belts  (14,16)  for transporting yarn packages from rows of spinning stations or winders to chutes (18,20), afterwhich they fall by gravity onto transport conveyor (4).  A delay mechanism comprising controller  (C);  sensors  (100,102)  connected to controller  (C);  and switches  (110,115),  also connected to controller (C), prevents yarn packages delivered via chutes (18,20) from colliding.  If textile machine (2) is a winding machine, yarn packages traveling from winders to chutes (18,20) have a sharply angled narrow portion on one side, making them easily susceptible to unwinding and tangling if the angled side is the first to enter chutes  (18,20).   In this scenario, a reorienting mechanism can be employed to rotate the yarn packages 180~ prior to their entrance into chutes (18,20).

Abstract: Un système d'exploitation pour un casino permet de contrôler le mouvement des fonds et de surveiller les activités de jeu dans un casino ou un établissement de jeu au moyen d'un réseau d'ordinateurs comprenant un ordinateur central et des ordinateurs de jeu individuels. Chaque joueur reçoit une carte de mise codée remise par un caissier. Aux tables de jeu, chaque emplacement de chaque joueur est équipé d'un panneau de commande comprenant un lecteur de carte dans lequel la carte des mises est introduite. Le panneau de commande comprend également un écran et un clavier électroniques. Depuis le panneau de commande, le joueur peut effectuer une mise et toutes les options à la disposition du joueur au cours d'un jeu particulier. Le système enregistre les jeux distribués à chaque joueur et au gagnant, et crédite ou débite la carte des mises en conséquence. Dans une variante, le système d'exploitation permet aux joueurs d'utiliser des jetons pour effectuer leur mise au lieu de la carte précitée. Les jetons sont marqués ou codés de façon à pouvoir être comptés une fois que les mises définitives ont été faites afin de déterminer la valeur de la mise de chaque joueur. Dans des jeux nécessitant le placement des mises dans certaines positions sur la table de jeu, chaque joueur peut être équipé d'un marqueur de mise qui est utilisé pour indiquer la position de ses mises sur la table, un écran tactile peut être utilisé pour placer des mises par simple toucher de la position requise sur l'écran, ou une console de commande éloignée bidirectionnelle peut être utilisée pour placer les mises. Ce système d'exploitation de casino est un système à architecture ouverte pouvant s'adapter aux différents besoins de chaque casino et peut être intégré à un réseau plus important permettant d'offrir aux utilisateurs différentes options de services et de divertissement, outre les options de jeu, à la fois sur place et dans des endroits éloignés.
