Patent DE-4400259-A1 (DE)
Title: Individual fuel injector control for IC engine
Inventor: ZHANG HONG DR
IPC: F02D45/00
Filed: 1994-01-07
Abstract: A control system for the individual fuel injection into the cylinders of an IC engine has a device (12), which, depending on the engine's operating parameters, determines when to discontinue the injection for at least one cylinder, and when to reinstate it. A mixture controller (14) adjusts the air/fuel mixture for each injector to a preset value. When the injection for one cylinder is to be discontinued, a sequential control unit first ensures the injectors of all cylinders receive a stoichiometric or lean mixture for a given time, before that cylinder is cut out. When the cylinder is to brought back into operation, all cylinders receive a stoichiometric or lean mixture for a given time, before normal injection is resumed.

Patent DE-4404669-A1 (DE)
Title: Thermally switchable electrical short-circuiting link, and a method for its production
Inventor: TEUSCHLER HANS-JOACHIM DR RER
IPC: H01H79/00
Filed: 1994-02-15
Abstract: The invention relates to thermally switchable electrical short-circuiting links in conjunction with a resistor component, which generally has a low resistance, which have common bases for the resistance and short-circuiting function connections, and a method for their production. A short-circuiting bracket which is firmly connected in DC terms to a base connection presses with a defined force against the second base connection, which is covered with a non-conductive coating. This coating consists of a dried solder paste whose solder alloys are present in a grain band of 3 to 100  mu m and are micro-encapsulated with organic polymers. An irreversible solder contact to the second base can be initiated in the adjustable temperature ranges from 70 to 260 DEG C in response to thermal influences resulting from an increased calorific amount of heat being developed in the resistor component. This ensures that the electronic or electrical apparatuses are protected in the event of a defect, and that the risk of fire is avoided.

Title: Wien's filter
Inventor: KOHASHI TERUO
IPC: H01J49/28
Filed: 1994-08-24
Abstract: A Wien's filter is used for secondary electrons which are emitted by a beam of primary electrons which scan a sample surface in a scanning electron microscope; the filter is used as energy analyser or as spin-rotating device for the charged particles in the beam. The beam is focused to the inner region of the filter in which a magnetic and an electric field are generated in such a manner that they cross over each other. The beam intersects the crossing fields at right angles. The surfaces either of the magnet-pole pieces (1, 2) or of the electrodes (3, 4) have a shape which approximately corresponds to the part of a hyperbola, while the other surfaces are essentially plane. Auxiliary electrodes (5, 6) extend parallel to the beam direction (z) between the electrodes. The filter has a large region which permits stigmatic focusing of a beam of large diameter. <IMAGE>

Abstract: Un dispositif pour déterminer l'écart entre les structures d'un modèle et celles d'un objet comparé, dans lequel les structures à comparer sont observées par superposition dans un espace de mesure, où une caractéristique de polarisation est transmise aux différents canaux d'images. Grâce au mouvement relatif entre l'usinage de l'objet superposée et l'espace de mesure et la séparation consécutive des canaux d'images selon leur caractéristique de polarisation, on obtient des courbes de signaux photométriques, à partir desquelles on peut déterminer quantitativement des erreurs de superposition des structures. En introduisant un prisme de rotation des images, on peut effectuer des mesures dans deux directions coordonnées: dans une trajectoire de faisceau d'observation dérivée, la caractéristique de polarisation est convertie en une caractéristique de couleur, de sorte qu'une représentation supplémentaire de l'image combinée de la superposition des structures est produite. La zone de balayage photométrique peut être rendue visible par éclairage vers l'arrière de l'espace de mesure et réflexion dans la trajectoire du faisceau d'observation.

Filed: 1994-03-23
Abstract: Afin notamment de connecter les extrémités de fils isolés avec une peinture résistant à des températures élevées, à des éléments de raccordement, jusqu'à maintenant le fil de bobinage était enroulé sous forme de boucle autour d'un élément de raccordement, et sous l'effet de l'application locale d'énergie, avec enlèvement de l'isolation, était connecté de manière mécanique et électrique à au moins un point de connexion. Selon l'invention, l'extrémité enroulée est maintenue avec une précontrainte autour de l'élément de raccordement lors de sa mise en place et simultanément des oscillations, notamment ultrasonores, sont injectées dans le système fil enroulé/élément de raccordement, afin d'appliquer de l'énergie au point de connexion. L'injection d'oscillations dans le fil s'opère de préférence en dehors du point de connexion. Comme les oscillations se propagent par l'intermédiaire du fil tendu et entraînent un mouvement relatif entre le fil enroulé et l'élément de raccordement, une couche isolante peut être rompue au moins partiellement et la connexion électrique à l'élément de raccordement s'effectue par soudage ultrasonore. A cet effet, une sonotrode est associée à la buse d'enroulement (10) afin de transmettre notamment les oscillations ultrasonores au fil de bobinage (5), de préférence en tant que partie de la buse d'enroulement (10).
