Abstract: A flip-flop circuit of set-reset type comprising complementary MOS transistors. 
     The flip-flop circuit comprises a first CMOS NOR circuit (10) to which set signal (S) is applied, and a second CMOS NOR circuit (12) having same arrangement as the first CMOS NOR circuit and to which reset signal (R) is applied. 
     Set signal (S) is the logical product signal (φ S .f S ) of first set signal (s s ) and second set signal (f s ). Reset signal (R) is the logical product signal (φ R .f R ) of first reset signal (φ R ) and second reset signal (fR). Neither of first set and reset signals (φ S , φ R ) becomes logic "1" simultaneously. Second set and reset signals (f s , f R ) are kept either unchanged during the time period when first set and reset signals (φ S , φ R ) are logic "1" or become logic "1" only during the time period when first set and reset signals (φ S , φ R ) are logic "1". 
     The first NOR circuit (10) comprises first and second transistors (Tr5, Tr4) of first conductivity type connected in series between first power supply terminal and third transistor (Tr2), third and fourth transistors (Tr2, Tr1) of second conductivity type, and a fifth transistor (Tr3) of second conductivity type connected between the node of second and third transistors (Tr4, Tr2) and the second power supply terminal. First set signal (φ S ) is applied to gates of first and fourth transistors and second set signal (f s ) to the gate of third transistor. The second transistor (Tr4) is gate-connected to the fifth transistor (Tr3).

Abstract: A process for producing dried alginate fibre material, in which wet spun insoluble alginate fibres are overlaid in a sheet (25) onto a more slowly moving liquid permeable conveyor (26) and are subjected to a dewatering drying operation, includes special treatment to eliminate or reduce bonding of the overlaid fibres at their points of contact or intersection. This is accomplished preferably by passing the dried sheet or web (50) that is produced through successive pairs of rollers (40, 42), driven at different speeds so as to pull the individual fibres longitudinally and break any existing inter-fibre bonds. Also, prior to and during initial drying of the sheet (25) of wet fibres application thereto of external mechanical forces is avoided and alcohol exchange to remove water may be used. The rollers (40, 42) may advantageously produce a stretch-breaking effect. The alginate fibre material (50') produced is particularly suitable for making up medical or surgical dressings and the like.

Abstract: This invention is the organizing of a key-accessed (indexed) file such that the file structure consists only of two levels, an index level and a data level. Both levels are permanently stored on a page-organized secondary storage medium that support random accessing of the pages. The index level is designed to have a fixed and specifiable number of pages and is stored entirely in the computer's memory when the file is in use. The fixed size of the index is made possible by having each index entry reference a data node with a growing (or shrinking) number of data pages as the file changes in size. Avoiding the accessing of more than one of the data pages referenced by an index entry is accomplished by means of an address computation that utilizes bits of the search argument.

Abstract: A system for sensing the spatial position of a moveable object (14) with respect to an energized conductive surface (10,12) whereby the spatial coordinates (x, y) of the object are determined. The system provides a means of accurately measuring the coordinates of the object with respect to a two-dimensional coordinate system independent of the third orthogonal dimension, thereby avoiding significant measurement errors due to variations ofthe object's position in the third orthogonal dimension. The system also ascertains the coordinate (z) of the object in this third dimension, which can then be utilized as an independent control variable in the system. Further, the system can accommodate a number of energized conductive surfaces over which the object may be positioned and can determine the spatial coordinates of the object with respectto any such surface. ln general,the system of the present invention can ascertain the generalized n-tuple position vector of the object with respect to each of a plurality of generalized, energized conductive surfaces. In any of the foregoing forms, the energized conductive surfaces can be transparent.
