Inventor: FISCHER BERNHARD
IPC: F23R3/40
Filed: 2002-04-10
Abstract: L'invention concerne un système de combustion destiné à un moteur à turbine à gaz. Ledit système de combustion est composé d'un sous-système de combustion à catalyseur (CAT) destiné à produire des produits de combustion dans un mélange carburant/air pauvre prémélangé en présence d'un catalyseur, et d'un sous-système de combustion à faibles émissions à sec (DLE) destiné à produire des produits de combustion dans un mélange carburant/air pauvre prémélangé. Des carburants gazeux et liquides sont employés dans le sous-système de combustion à faibles émissions à sec tandis que seuls des carburants gazeux sont employés dans le sous-système de combustion à catalyseur. Au démarrage, et dans des conditions de charge faible, le moteur fonctionne sur le sous-système de combustion à faibles émissions à sec, et commute le processus de combustion sur le sous-système de combustion à catalyseur dans des conditions de charge importante. Ainsi, le système de combustion selon l'invention permet de combiner les avantages de processus de combustion à faibles émissions à sec et à catalyseur de manière que le moteur à turbine à gaz fonctionne sur une gamme de fonctionnement complète avec un rendement élevé tout en minimisant les émissions d'oxydes d'azote et de monoxyde de carbone.

Title: Monostable multivibrator
Inventor: MIURA KATSUNORI
IPC: G11B20/06
Filed: 1990-07-17
Abstract: A monostable multivibrator is formed in a monolithic integrated circuit along with a voltage controlled oscillator (VCO). The VCO and the monostable multivibrator respectively includes capacitors. A center frequency of the VCO is controlled by a control signal from a low-pass filter which receives an output of a phase comparator. A current from a constant current source circuit is adjusted to be in proportion to a level of the control signal. The capacitor of the monostable multivibrator is charged by the current thus adjusted from the constant current source circuit in response to a trigger pulse. A period from a time when the charge is started to a time when a charged voltage of the capacitor reached a predetermined value becomes a metastable period of the monostable multivibrator.

Title: Self biasing protection arrangement for a cathode ray tube
Inventor: GEORGE JOHN B
IPC: H04N3/20
Filed: 1991-04-25
Abstract: ABSTRACT A source of kine supply voltage is coupled to a video amplifier that drives a cathode of a cathode ray tube of a projection television receiver via a self biasing diode. When, due to, for example, a fault condition, the kine supply voltage is lost, the self biasing diode decouples the cathode of the cathode ray tube from supply return terminal of an ultor supply voltage to form a high impedance, low capacitance at the cathode of the cathode ray tube. A beam current develops a self biasing voltage at the cathode of the cathode ray tube that substantially reduces the beam current to provide protection against a damage to a screen of the cathode ray tube.
