Abstract: An electrodynamic loudspeaker (1) has a diaphragm comprising a central part (2) and a peripheral part (3), rand a voice-coil device (9, 10) coupled to the central part (2). The ratio S 1 /S 1  complies with the relationship 0.5 ≦ S 2 /S 1  ≦ 6, where S 1  and S 2  are the surface areas of the central part (2) and the peripheral part (3) respectively. The ratio m 2 /m 1  complies with the relationship 0.5 ≦ m 2 /m 1  ≦ 8 where m 1  and m 2  are the mass of the central part (2) and the voice-coil device (9, 10) and the mass of the peripheral part (3) respectively. Further, the compliance imposed on the diaphragm by the space (6, 6') defined by the diaphragm (2, 3) and the chassis (4) and/or the magnet system (7) is smaller than the compliance of the diaphragm itself (Fig.1). Thus it is possible to realise a car loudspeaker which has a specific dip in its frequency response characteristic P (Fig. 2a), measured in an anechoic room.

Abstract: An air-fuel ratio control system for internal combustion engines has an air-fuel ratio sensor (8) mounted in an exhaust pipe (7) of an internal combustion engine (1) and is adapted to produce an output indicative of the air-fuel ratio of a mixture supplied to the engine, on the basis of the composition of exhaust gases in the exhaust pipe (7). The air-fuel ratio sensor (8) is provided with an electric heater (100) for heating the air-fuel ratio sensor (8). The system further has a temperature sensor (10) for sensing the temperature of the internal combustion engine (1) or the ambient air temperature, and an engine operation sensor (211) adapted to sense whether the engine has been stopped, through detection of the state of the ignition switch. When the engine operation sensor has sensed that the internal combustion engine has been stopped while the temperature sensed by the temperature sensor is below a predetermined level, the electric heater is supplied with power for a predetermined time after the stop of the engine so as to evaporate any water content clinging to the air-fuel ratio sensor.

Abstract: The method makes it possible to correct deviations in copying behaviour occurring during the copying of colour slides of different makes. For this purpose, a test slide, serving as an original, is measured twice for its transmission of red, green and blue light, once with filters of a transmission corresponding to the spectral sensitivity of that of the colour copying paper, and once with filters of a transmission corresponding to the corresponding stimulation curves of the human eye. A correction signal is derived from the difference in the measurements and adjusts the colour balance of the colour copy to match the visual colour balance of the original slide.

Abstract: A package element (1) is made from a synthetic foam by automatically injecting, with the aid of a dosing apparatus according to the invention, foam into a broken mould obtained from a sheet of thermoplastic material (2) previously shaped by vacuum forming. (Figure 1). The invention also enables articles placed in a package to be encapsulated. Detection of the contour is performed by a series of acoustic or optical sensors distributed at regular intervals through a conveyor belt conveying three-dimensional articles whose dimensions are sampled, for example, every 5 cm. These data are processed instantaneously by a computer (13). The invention also relates to a system for packing different articles deposited in a box with fold-down flaps (27). By checking that the foam swells up to the folds of the box, it is possible to produce, in a single operation, a box covered internally with foam on the six sides. <IMAGE>

Abstract: Un procédé, un dispositif et un matériau, servant à obtenir un affichage à cristaux liquides à commutation rapide, utilise l'effet ferroélectrique du matériau sous forme de cristaux liquides à phase smectique chirale. Afin d'obtenir une apparence uniforme, le matériau sous forme de cristaux liquides est disposé de façon à présenter un grand pas cholestérique à une température proche d'une température de transition de phase smectique/cholestérique. Ce grand pas cholestérique permet aux molécules de cristaux liquides de se refroidir, passant ainsi de la phase cholestérique à la phase smectique, avec un alignement uniforme. Le matériau smectique est contenu dans une cellule entre des parois (2, 3) portant des électrodes (5, 6) et traitées en surface, afin de permettre un alignement homogène du matériau sous forme de cristaux liquides (7).

Abstract: Un détecteur de pression capacitif (47, 75, 100, 130, 170, 190) fabriqué suivant un procédé en discontinu permet d'isoler l'élément de détection (12, 102, 134, 183) et les conducteurs par rapport au milieu de pression et est également isolé contre les contraintes. Le détecteur de pression (47, 75, 100, 130, 170, 190) est conçu suivant une construction en sandwich comprenant une tranche de silicium (10) qui est attaquée d'un côté pour former des cavités (14) en plusieurs endroits désirés de manière à constituer des diaphragmes déflecteurs (12, 102, 134, 183), dont une surface joue le rôle de plaque de condensateur. Une couche de verre (20) est métallisée sur les deux côtés et présente des trous percés dans des endroits qui sont alignés avec les diaphragmes formés sur la tranche de silicium (10). La couche de verre (20) est liée de manière anodique à la tranche de silicium pour former un entrefer capacitif de quelques microns par rapport à ladite surface de chaque diaphragme (12, 102, 134, 183). L'assemblage de la couche de verre métallisé (20) et de la tranche de silicium (10) est dans une forme préférée prise en sandwich entre deux couches supplémentaires (30, 42, 154, 161, 163), et sont liées ensemble dans le vide. Le sandwich à quatre couches est ensuite découpé en plusieurs détecteurs individuels (47, 75, 100, 130, 170, 190). L'ensemble initial peut être formé pour atténuer les temps de réponse des diaphragmes et réduire au minimum les risques de faux signaux au niveau d'entrées de haute fréquence.

Abstract: All kinds of material, apart from particularly solid or hard materials such as steel, can be cut with a fine water jet. The cutting efficiency can be increased by adding abrasives to the water. The abrasive speeds attainable are insufficient, however, to sever steel, for example. According to the invention, this is possible, however, when the jet of fluid is interrupted or at least reduced preferably before mixing with the abrasive and only then brought into contact with the abrasive. <IMAGE>

Abstract: A ceramic material can be produced by the method, in which a superconducting metal oxide phase having a high transition temperature and based on the Me1-Me2-Cu-O system is formed by means of a heat treatment. The metal components Me1 and Me2 contain at least one rare earth metal or yttrium or an alkaline earth metal. The method is intended to facilitate the construction of bodies made of the brittle metal oxide with any desired shape. For this purpose, the invention provides that a master alloy consisting of the metal components of the system involved are fused in the desired concentration ratio, that an amorphous or finely crystalline intermediate product is then formed from said melt of the master alloy using a rapid quenching technique and that, finally, the intermediate product is subjected to an oxidation treatment with simultaneous heat treatment to form the desired superconducting metal oxide phase avoiding melting.

Abstract: A safety jaw for a ski binding, having a holding-down device for the sole, has a height-adjustable tread-plate arrangement (37) for the front part of the sole (35) of a ski boot (36). The tread-plate arrangement (37) consists of a base plate (11), which rests on the upper side of the ski (15), and, arranged above, a tread plate (12) which interacts with the base plate (11) via inclined surfaces (19, 19'; 20, 20'), which fall or rise in the longitudinal direction of the ski, in such a manner that a relative displacement of the tread plate (12) and of the base plate (11) in the longitudinal direction of the ski leads to a height adjustment of the tread plate (12) in relation to the ski (15). Between the base plate (11) and the tread plate (12), there are also provided control surfaces (13, 14) which run at an angle to the transverse direction of the ski, interact with one another, adjoin one another and define the relative position of the base plate (11) and of the tread plate (12) in the longitudinal direction of the ski. Upon a relative displacement of the control surfaces (13, 14) in the transverse direction of the ski, the base plate (11) and the tread plate (12) change their relative position in the longitudinal direction of the ski, as a result of which the height of the tread plate (12) relative to the base plate (11) or to the ski (15) is changed. <IMAGE>
