    Abstract: Semiconductor power devices of improved RBSOA and turn-on switching time for use with inductive as well as resistive loads. The emitter (9) of a power transistor has the form of a substantially closed ring of small cross section but great peripheral length, folded into a tortuous configuration so that emitter metallization (12) on the enclosed area can provide low series resistance. In a preferred embodiment the emitter (9) takes the form of the perimeter of a double sided comb with emitter finger regions (23) protruding away from a central spine (8). Improved RBSOA and turn-off times are achieved by the specified emitter geometry and the given width ratios for emitter (10 and 22), base (25 and 26) and metal (24). These ratios permit the device to be scaled to other overall dimensions.

    Abstract: Detector monitoring the function of the stator and rectifying diodes in a multiphase alternator battery charging system (20). A circuit combines individual phase signals form the alternator (22) to form an artificial neutral at which a normally symmetric wave signal is present. A first comparison means detects deviations in the normally symmetric wave signal greater in value than a first threshold voltage level. A second comparison means detects deviations in the normally symmetric wave signal lesser than a second threshold voltage level. Means coupled to the first and second comparators produce an output signal whenever the normally symmetric wave signal deviates above the first threshold voltage level or below the second threshold voltage level. The detection of asymmetry in the normally symmetric wave signal indicates a fault in the stator or rectifying diodes of the alternator.

    Abstract: In a shared contact electrically programmable read only memory, decoding circuitry is provided to prevent unwanted device programming due to sneak paths to ground. A two input NAND gate (15, 16) is coupled between adjacent column select lines. If either of the adjacent column select lines are energized, a data line will be enabled. Thus, for each column line energized, only two data lines will be enabled and only one of these will carry a voltage for enabling a memory device.

    Abstract: Un amplificateur operationnel (18) est capable d'effectuer selectivement une variete de fonctions de circuits. Un amplificateur operationnel simple (18) utilise des condensateurs commutes (24, 32 et 36) pour echantillonner-bloquer un signal d'entree VIN pour etablir un pole de basse frequence, pour appliquer l'echantillon sur une capacitance de sortie (47 et 48) et charger la capacitance, et pour comparer le signal d'entree VIN a une reference VAG. Le circuit a multi-fonctions (12) permet une grande conservation dans la zone circuit ainsi qu'une versatilite des applications de circuit. Un mode de realisation de l'invention consiste a utiliser un convertisseur numerique/analogique de compression-extension (14) ayant un condensateur qui peut etre utilise comme capacitance de sortie (47 et 48) du circuit de l'amplificateur operationnel (12). Le convertisseur numerique/analogique utilise un convertisseur numerique/analogique a echelle R (52) couple directement a un convertisseur numerique/analogique C (50) et possede une structure de commutation qui est plus simple que les circuits comparables de l'art anterieur. Le convertisseur numerique/analogique (14) est asynchrone et possede une capacite programmable de conversion MIC suivant les lois A- et Mu-225. Un circuit filtre de reception de l'amplificateur operationnel (16) est couple directement au convertisseur numerique/analogique C (50), lequel circuit utilise le convertisseur numerique/analogique C (50) comme condensateur d'entree, eliminant ainsi le besoin d'utiliser un amplificateur tampon et permettant au convertisseur numerique/analogique (14) d'etre utilise a la fois pour la conversion analogique/numerique et la conversion numerique/analogique.
