Abstract:
An ignition coil mounted on a spark plug to provide an individual electrical power supply thereto is disclosed. The coil includes an inner secondary winding (2), an outer primary winding, a flux return armature (9) and a housing (4). Said housing (4) surrounds only the secondary winding as the primary winding is coiled around the outside of the housing and in turn surrounded by the flux return armature.
Abstract:
Pour guider un avion vers un poste d'accostage, on forme, à partir d'un point déterminé à proximité du poste d'accostage, une image à deux dimensions d'une zone d'approche vers le poste, en infrarouge thermique. On repère, dans l'image, l'apparition et les emplacements des pneumatiques (24) des roues d'un avion lorsqu'il arrive dans la zone d'approche. On calcule, à partir des caractéristiques mémorisées de l'avion attendu au poste et des dits emplacements, la distance entre l'avion et le poste ainsi que l'écart entre la trajectoire instantanée de l'avion et la trajectoire d'arrivée au poste d'accostage dans une orientation déterminée de l'avion. On communique au pilote de l'avion, par exemple sur un panneau (18), des indications sur l'écart entre la position de l'avion et la trajectoire d'arrivée au poste d'accostage, élaborées à partir du résultat du calcul.
Abstract:
In an active matrix liquid crystal display device the liquid crystal layer (10) has a non-twisted homogeneously aligned configuration while the liquid crystal cell is placed between two crossed polarizers (26,28) having their transmission direction at 45° with respect to the liquid crystal director at the cell-boundary. A negative birefringent retardation film (34,36) is positioned between the liquid crystal cell and one of the polyrizers in such a way that the optical axis of the retardation film is parallel to the liquid crystal boundary director while the absolute value of the retardation of the retardation film is equal to the effective retardation of the liquid crystal layer when no voltage is applied. In a preferred embodiment of the present invention, this one retardation film is replaced by two foils (34,36) of the same type which each have a retardation value which is equal to half the retardation value of the one film and which are placed on one side of the liquid crystal cell with their optical axis' parallel to the liquid crystal boundery-director. To achieve a bright state at high voltage, the liquid crystal retardation is in the range 0.15-0.35 micron, and preferentially in the range 0.20-0.30 micron.
Abstract:
In a liquid-crystal display device having a pi-cell configuration between crossed polarizers and having a liquid-crystal retardation value such that it is possible to switch from a Bright state at low voltage to a Dark state at high voltage, the voltage for setting the Dark state can be lowered by making use of retardation films whose optical axes are parallel to the cell surfaces and perpendicular to the projection direction of the liquid-crystal director on the cell surfaces. Positioning of said films on both sides of the pi-cell in such a way that the total film retardation on the one side is equal to that on the other side results in angle-of-view-dependent transmission characteristics having better symmetry than in the case of the films being positioned on one side.
