Abstract: A spacecraft (10) incorporating momentum sources such as spinning momentum wheels (14, 16) having momentum vectors or components thereof oriented along the desired axis (z) of rotation of the spacecraft (10). The rotation axis (z) of the spacecraft (10) is nominally any one of the three principle momentum of inertia axes of the body. Proper adjustment of the spin rate of the main body relative to the magnitude of the moment sources angular momentum will insure that the spacecraft (10) will spin about the desired axis (z) in a passively stable way even though the rotational axis is not the principle axis of maximum moment of inertia.

Abstract: A floating gate transistor is programmed by a conventional charge pump providing drain programming current, typically held below about 1 µA. The drain current can be limited by connecting a resistor between the source and ground, or by limiting the transistor control gate voltage. Instead, a charge pump is coupled to the drain while the control gate is repetitively pulsed. Each time the control gate is pulsed, the transistor turns on, and although the drain is initially discharged through the transistor, some hot electrons are accelerated onto the floating gate, and eventually the floating gate is programmed. The erase gate voltage may be raised to enhance programming efficiency.

Filed: 1990-04-20
Abstract: A bleaching product and a method of removing soils from fabrics by contacting the fabrics in an aqueous wash solution with a product comprising a peracid precursor, a source of hydrogen peroxide and a source for delayed release of an acid into the wash solution to initially permit effective in situ formation of peracid, the acid thereafter reducing the pH of the wash solution for enhancing bleach performance of the peracid. The source of the acid may be included in the bleaching product, for example, as an acid of delayed solubility, an acid coated with a low solubility agent or an acid generating species, or independent of the bleaching product. The acid source is selected to be compatible with the peracid or precursor and adjuncts. The method for removing soils thus comprises contacting the fabrics in an aqeuous solution with a peracid precursor and a source of hydrogen peroxide, initially raising the pH of the solution for effective in situ formation of peracid and then reducing the pH for enhancing bleach performance of the .peracid.

Abstract: To fabricate polarization retaining couplers, the fibers must be kept untwisted and must be maintained parallel to one another, and the major axes of the polavitation-retaining single mode (PRSM) (115,116) fibers must be maintained substantially parallel to one another. It is noted that this orientation includes that orientation wherein the major axes are substantially coaxial. The method of the present invention is characterized in that the fiber coating material is utilized to facilitate the alignment of the major axes of the fibers. In a first described embodiment, each fiber is provided with a rectangularly shaped coating (117,118), and the two larger flattened sides of the coating are specifically oriented with respect to the major and minor axes of the PRSM fiber therein. Cores (141) and (143) of optical fibers (115) and (116), respectively, are elliptically-shaped, and the minor axis of each core is parallel to the long flat sides of the rectangularly-shaped coating. 
     In one embodiment, tube (110) is heated and collapsed onto fibers (115) and (116) in a step that is separate from the step of stretching the midregion of tube (110). The flame from burner (129) is directed onto midregion (128) to heat glass tube (110) to its softening point. Burner (129) may remain stationary, or it may traverse midregion (128) in the direction toward vacuum source (126) as shown by arrow (130). It is an optional feature of the tube collapse step to apply a vacuum source to both hollow filaments (121) and (122), in which case the direction of burner traverse is immaterial. Midregion (128) becomes a solid region that is preferably free of air lines, bubbles, or the like.

Abstract: Part of a melt vessel (6) is formed from a porous member (6a) which is permeable to gas and impermeable to melts (2). Alternatively, a bottomed cylindrical partitioning member (11) immersed in a melt in the melt vessel (6), or part of a circulating vessel (15) through which the melt circulates, or a dam (17) disposed in the course of circulation of the melt in the melt circulating vessel (16) is formed from the porous member. 
     Vacuum pump is used to suck gas from the melt or gas produced by a reaction at the interface between the melt and the porous member through the porous member, to the side of that surface of the porous member which is not in contact with the melt and kept at a vacuum or at reduced pressure. 
     Then, the pressure at the interface between the melt and the porous member is lowered, and a space which is in a vacuum or at reduced pressure can be easily created in the melt. Thus, solute ingredients of the melt nucleate easily to form gaseous substances, so that the gaseous substances are sucked into said space and removed from the melt.

Abstract: In order to solve a symmetric linear system given by Au = b, where A represents a symmetric coefficient matrix equal to a three-term sum of a diagonal matrix plus an upper triangular matrix plus a lower triangular matrix, b represents a right-hand side vector, and u represents a solution vector, a device calculates the solution vector by using the right-hand side vector, the diagonal matrix, and the upper triangular matrix. Supplied with an array (JA) representing a column number of the upper triangular matrix, a pointer array constructing section (11) constructs a pointer array (JL) which points to the lower triangular matrix. Supplied with an array (AA) and the array (JA) which collectively represent a combination of the diagonal matrix and the upper triangular matrix, a matrix decomposing section (12) decomposes the array (AA) into an approximate matrix (M) which approximates the symmetric coefficient matrix. A first product calculating section (16) calculates a first product vector (y) by using the array (AA), the array (JA), a first vector (x), and the pointer array (JL). A second product calculating section (17) calculates a second product vector (y') by using the approximate matrix (M) and the second vector (x'). An iterative calculating section (18) carries out iterative calculation on the array (AA), the array (JA), an array (B) representing the right-hand side vector, the first and the second product vectors (y) and (y'). The iterative calculating section (18) iteratively provides the first and the second product calculating sections (16) and (17) with the first and the second vectors (x) and (x'), respectively. The iterative calculating section (18) produces the solution vector (u). The device may be supplied with the lower triangular matrix instead of the upper triangular matrix.

Abstract: A method and apparatus are provided for producing multiple, frequency-addressable beams employed in a satellite communication system. The beams are effectively scanned over an area of the earth in order to communicatively interconnect small communication terminals on the earth. Multiple beams are formed which can be scanned independently of each other in the direction of scanning. Two or more beam formers (104, 106) are coupled in parallel and feed a single array of antenna elements (30). The outputs of the beam formers (104, 106) are combined in summers (98) and are then amplified by power amplifiers (38) and applied to excite the array elements (30). Phase shifters (92-96) are coupled between the beam formers (104, 106) and the array elements (30) to shift the phase of the beam signals and thereby aim or shift the beams in a direction orthogonal to the scanning direction in order to provide the desired coverage over the earth (Figures 9A + B).

Abstract: An intelligent machining system employs a neural network for calculating machining conditions on the basis of attribute data of a workpiece and a grinding machine. The system comprises a reference machining condition calculating unit, a neural network which receives the attribute data and provides corrections, and a correcting unit for correcting the reference machining conditions by using the corrections. Corrections which cannot be determined by means of empirical expressions or theoretical expressions are determined appropriately by the neural network previously learned. The system determines corrections for the machining conditions on the basis of machining errors decided by a neural network. The system also detects time-series machining phenomena by sensors, processes the output detection signals of the sensors by a neural network to obtain machining circumstance data. The feed rate of the tool is controlled by a fuzzy inference on the basis of the machining circumstance data.
