Abstract: L'invention concerne un procédé permettant de régler le moment d'allumage en fonction des variations de charge connues se produisant dans un moteur à combustion interne. Selon ce procédé, lorsqu'un seuil de variation de charge correspondant à une augmentation de charge définie est dépassé, le moment d'allumage est retardé par rapport à une valeur de base du moment d'allumage. Pour gagner du temps de calcul, il est prévu d'utiliser une nouvelle valeur de base plus grande (alphaBasis), en fonction des variations de charge connues, à la place de la valeur de base (alphaz1) du moment d'allumage.

Abstract: On applique le vecteur approprié d'une liste de vecteurs de mouvement possibles à chaque région d'une image vidéo. On détermine une valeur d'image pour cette région, pour chacun des quatre champs successifs et pour chacun des vecteurs de mouvement possibles. On compare les valeurs des quatre champs et quand ces valeurs sont sensiblement identiques pour un vecteur donné, on suppose qu'il s'agit du vecteur approprié pour cette région. On peut également affecter les vecteurs appropriés à des régions dont l'arrière-plan est caché ou découvert, en comparant les différences inter-champ et en déterminant les régions dans lesquelles les différences inter-champ sont grandes pour la paire centrale et une paire extérieure, et petites pour les autres paires de champ extérieures. Pour générer des régions correspondant à un arrière-plan caché, on utilise seulement l'information provenant des premiers champs et pour générer des régions correspondant à un arrière-plan découvert, on utilise seulement l'information provenant des derniers champs.

Abstract: Un appareil pour essais de dureté de métaux et alliages permet de fournir des valeurs comparatives de dureté Vickers ou Brinnel par lecture directe au moyen d'un pénétrateur (17) en matériau conducteur présentant une résistivité élevée. L'ampleur de la pénétration produite détermine une certaine résistance de contact électrique entre le point de pénétration (20) et l'échantillon (21), qui peut être mesurée par un appareil de mesure approprié, par exemple un pont de Wheatstone (W). Après étalonnage de l'appareil à l'aide d'un flan ou d'un échantillon témoin de dureté connue, le pénétrateur (17) est chargé de manière à pénétrer dans l'échantillon d'essai (21) jusqu'à atteindre à nouveau la même résistance de contact électrique que sur l'échantillon témoin. La différence entre les charges appliquées permet une évaluation comparative de la dureté qui peut être lue directement sur une échelle appropriée sans nécessiter des mesures au microscope de l'ampleur de la pénétration. Cet appareil pour essais de dureté convient notamment pour une utilisation sur le terrain et pour tester des surfaces internes.

Abstract: An anisotropic conductive material includes micro-capsules dispersed in a bonding resin. The micro-capsules contain, as a filler material, a conductor and a polymerization initiator, a curing agent or a curing promotor. A wall member encapsulating the filler material is formed of a thermoplastic or thermosetting insulative resin. Therefore, if the micro-capsules in the anisotropic conductive material are broken or destroyed by pressure or both of pressure and heat, electrical connection can be established between electrode pads and electrode terminals of a wiring substrate through the conductors contained in the micro-capsules. Simultaneously, the polymerization initiator, the curing agent or the curing promotor flows out, so that the insulative bonding resin is solidified. Thus, the anisotropic conductive material has a high connection reliability, a good reproducibility, an excellent packaging workability, and excellent shelf stability.

Abstract: A filtering material for effectively adsorbing not only conventional foreign material such as dust, odoring gaseous substance but also very fine foreign material such as virus, bacteria, fungus, pollen or the like is disclosed. The filtering material includes as essential components porous apatite particles, a water soluble glucan and a sheet-shaped raw material in which the porous apatite particles are included with the aid of the water soluble glucan serving as a binder. 
     A method of producing a filtering material of the foregoing kind is practiced by way of a step of preparing an aqueous treatment solution in which porous apatite particles of 0.5 to 40 % by weight and a water soluble glucan of 0.5 to 15 % by weight are dispersively dissolved, a step of dipping a sheet-shaped raw material in the aqueous treatment solution, and a step of drying the sheet-shaped raw material while the porous apatite particles are included in the sheet-shaped raw material with the aid of the water soluble glucan serving as a binder. Alternatively, a step of spraying the aqueous treatment solution to surfaces of a sheet-shaped raw material may be substituted for the step of immersing a sheet-shaped raw material in the aqueous treatment solution. It is preferable from the viewpoint of practice use that the porous apatite particles are included in the aqueous treatment solution by a quantity of 0.5 to 30 % by weight.
