Abstract: A semiconductor component has a semiconductor body comprising a blocking pn junction, a source zone of a first conductivity type connected to a first electrode and bordering on a zone forming the blocking pn junction of a second conductivity type complementary to the first conductivity type, and a drain zone of the first conductivity type connected to a second electrode. The side of the zone of the second conductivity type facing the drain zone forms a first surface, and in the region between the first surface and a second surface located between the first surface and the drain zone, comprises areas of the first and second conductivity type nested in one another. The second surface is positioned at a distance from the drain zone such that the areas of the first and second conductivity type nested in each other do not reach the drain zone.

Abstract: L'invention concerne un équipement central simplifié pour système téléphonique sans fil qui fait appel à un réseau de distribution large bande existant (114) afin d'acheminer les signaux téléphoniques entre un réseau téléphonique existant (115) et des émetteurs-récepteurs distants dans des cellules ou des zones définies. La simplification tient à la réduction des étapes de transposition de fréquence entre les éléments de l'équipement considéré, via l'utilisation de la même fréquence porteuse aussi bien pour le traitement des signaux dans les éléments dudit équipement que pour la transmission des signaux téléphoniques entre éléments. Ladite simplification s'applique à des systèmes téléphoniques sans fil de formatages différents.

Abstract: The battery powered or 120 VAC powered environmental condition detector of the present invention is designed to provide an early warning of the presence of an environmental condition (smoke or carbon monoxide gas or natural gas or propane gas or any multiple combination of these offending agents) to persons in remote areas of a building. The detector sensing the environmental condition emits an audible tonal pattern alarm, while transmitting a radio signal directly to other environmental condition detectors to activate their alarms and to activate an electronically stored human voice recording (or synthesized voice) that indicates the location of the environmental condition detector sensing the environmental condition, or the type of environmental condition, or both. Rechargeable light modules separate from the detector are included that receive the signal from the detector sensing the environmental condition and illuminate areas and paths of egress for the duration of the alarm condition or in case of 120 VAC power failure. All components of the system are easy to install due to the modular design and conventional power sources. An intermittent activation of the electronic circuitry in the detector unit may be used to conserve battery energy in the battery powered embodiment.
