Abstract: According to the present invention, a concept of functional quantities indicative of quantified functional degrees of such lower-level functions as "clearer characters", "cleaner background", and "thicker characters", which are subordinating to a qualification-oriented function of "more attractive characters". Characteristic patterns of functional quantities F1, F2 and F3 of the lower-level functions for physical parameters (for example, the surface potential of a photoreceptor body) are prepared. When a fault repair is implemented by changing a value of a physical parameter, a tradeoff is made between lower-level functions which are influenced by the physical parameter. That is, taking into account the functional quantities F1, F2 and F3 of the lower-level functions, the value of the physical parameter is set so that the functional quantity of the function of "more attractive characters" is maximized. By introducing the concept of the functional quantities indicative of the quantified functional degrees of the functions, a flexible self-repairing function can be realized, thereby optimizing a repair operation.

Abstract: A fluid flow control valve comprises first (12) and second (14) electrically conductive body members separated by an electrically active means (16) having electrical resistance. A valve actuation member (20) slidably locates within the second body (14) member making a sliding electrical contact therewith. The valve actuation member (20) can move from a first position spaced from the first body (12) member to a second position electrically connecting the first body (12) member with the second body (14) member thus forming a low resistance electrical connection. In its first position spaced from the first body member (12), the resistance of the electrical connection between the body members (12, 14) depends on the electrical resistance of the separation means (16). An electrical circuit connected across the body members (12, 14) including a current limiting resistor (R3) forms a voltage splitter circuit with the separation means (16) to enable an output voltage signal indicative of contact of the valve actuation member (20) with the first body member (12) to be obtained.

Abstract: A logic system comprising one or more logic networks (LNA0..LNA3) that can perform a variety of logic functions, either by configuration of a multi-function network or by a switched network comprising several sub-networks each of which performs one or more dedicated logic functions. Each logic network is functionally separate from but operatively associated with one or more programmable circuits (PROG) from which that logic network receives logic control signals (LSFA0..LSFA3) to select a particular logic function or functions to be performed by the logic network(s). The programmable circuit also supplies separate logic signals (LSCA0..LSCA3) to control the operation of the logic network(s) in implementing the selected logic function. In this manner the programmable circuit (PROG) can essentially be dedicated to selecting the function and controlling the operation of the selected function of the logic network(s) and is relieved of significant functional overhead associated with data manipulation typically performed by conventional operation of logic network(s). This can permit a smaller size programmable logic, gate or memory array to be used to control a logic operation of a given complexity, or a given size of array to control more complex operations. Both the programmable circuit(s) and the logic network(s) can be integrated in a single semiconductor chip.

Abstract: A method for fabricating a periodic dielectric structure which exhibits a photonic band gap. Alignment holes are formed in a wafer of dielectric material having a given crystal orientation. A planar layer of elongate rods is then formed in a section of the wafer. The formation of the rods includes the step of selectively removing the dielectric material of the wafer between the rods. The formation of alignment holes and layers of elongate rods and wafers is then repeated to form a plurality of patterned wafers. A stack of patterned wafers is then formed by rotating each successive wafer with respect to the next-previous wafer, and then placing the successive wafer on the stack. This stacking results in a stack of patterned wafers having a four-layer periodicity exhibiting a photonic band gap.

Abstract: La présente invention concerne un procédé de production d'un bâtonnet antitranspiration solide, comprenant un sel antitranspiration d'aluminium particulaire, en suspension dans un excipient anhydre. Cet excipient comprend un composant à point de fusion élevé qui fond à 70 °C ou plus. Ce procédé consiste à chauffer l'excipient dans une cuve de mélange fermée, à une température dépassant 70 °C, de préférence dépassant 75 °C, afin de faire fondre le composant à point de fusion élevé, à ajouter le sel antitranspiration à l'excipient, et à refroidir l'excipient afin d'obtenir un bâtonnet antitranspiration solide. L'amélioration de la présente invention consiste à refroidir l'excipient en dessous de 70 °C, de préférence à environ 65 °C ou moins, mais au-dessus du point de solidification avant d'ajouter le sel antitranspiration, et de maintenir l'excipient au-dessous de 70 °C, de préférence à environ 65 °C ou moins, pendant et après l'ajout du sel antitranspiration, ce qui empêche ainsi le sel antitranspiration de s'agglomérer en grosses particules, notamment en particules de plus de 60 microns.
