Patent CA-2202464-C (CA)
Inventor: DENT PAUL W
IPC: H03F1/02
Filed: 1995-10-10
Granted: 2005-06-28
Abstract: Circuit d'amplification de puissance conçu pour produire un signal de sortie s'appliquant à une charge et pouvant produire plus de deux puissances de sortie et comportant au moins deux amplificateurs présentant un rendement optimal quelle que soit la puissance de sortie. Ledit circuit peut fonctionner en différents modes dont celui consistant à activer un amplificateur pendant un cycle entier d'un signal d'entrée, à amplifier ou activer un amplificateur en fonction d'un signal de commande indépendant du signal de sortie amplifié. Dans les deux cas, les amplificateurs restants sont désactivés et le couplage entre les amplificateurs empêche les amplificateurs désactivés de freiner le flux de puissance allant de l'amplificateur activé à la charge. Selon un autre aspect de l'invention, le rendement optimal pour différents niveaux de puissance de sortie s'obtient en couplant chacun des amplificateurs à une alimentation commune et à la charge par l'intermédiaire d'un circuit d'adaptation d'impédance, avec une impédance différente pour chaque amplificateur. Le circuit d'adaptation des impédances peut comporter un transformateur push-pull muni de prises permettant de choisir différents rapports de spires entre les différents amplificateurs et la charge. Le circuit d'adaptation peut par ailleurs comporter plusieurs lignes quart d'onde reliées chacune par l'une de leurs extrémités à la charge, et par l'autre, à l'un des amplificateurs par l'intermédiaire d'un symétriseur.

Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N21/647
Filed: 1993-03-25
Granted: 2001-07-24
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. 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 stream 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.

Abstract: A control for delivery system made up of a plurality of variable output feed sources each with an independently variable input of material defines the capability of each of the feed sources based on the level of material and combines these capabilities to define a total capability of the delivery system. An output setpoint for each source is determined based on its capability and a required setpoint is set based on a desired end product characteristic which is used to define a production rate based on total capacity, required setpoint and the production line characteristics. The process is iterative so that the production rate, e.g. speed of the line is varied iteratively depending on the then current capabilities of the feed sources of the system and the footprint of the feed sources are adjusted based on their sensed capabilities thereby to maximize production line speed based on capability.

Abstract: A magnet device with double fixing positions for changing the magnetic circuit is provided, and includes an external housing whose inner edge is fitted with a coil The inside of the external housing includes a space for the axial movement of an iron core. The external housing and a positioning cover at the opening end of the housing are made of metal with excellent magnetic conductivity. The iron core is connected to a permanent magnet which is fixed at the inner side of the positioning cover. A drive circuit is provided whereby a positive impulse voltage will be output and the electrical energy is saved in a capacitor when the power is switched on. A discharge current is created to output a negative impulse voltage after the power is switched off, and the positive and the negative impulse voltages serve to make the coil change the direction of the magnetic force by the excitation process, so that a push force or a pull force on the iron core will be created for movement thereof. The permanent magnet will be forced to change the magnetic circuit and the iron core under ordinary circumstances will be kept at the pre-arranged position without continuous waste of electricity. Not only can this save electric energy, but it will avoid creating an over-heated state or a short circuit, so that a dangerous situation is prevented and the useful life of the device is extended.
