Abstract: In a musical tone synthesizing apparatus which synthesizes sounds of a non-electronic musical instrument containing a sound-generation element and an activating element, there is provided a loop circuit and an excitation circuit. In case of the piano, the sound-generation element and activating element respectively correspond to its string and hammer. On the basis of the operation of the activating element, the excitation circuit computes a relative displacement between the sound-generation element and activating element. Based on the computed relative displacement and its variation in a lapse of time, repulsion force applied between them is computed under consideration of the elastic characteristic and viscous characteristic of the activating element. Thereafter, the excitation circuit outputs an excitation signal, corresponding to the computed repulsion force, to the loop circuit so as to simulate the sound-generation mechanism of the non-electronic musical instrument.

Abstract: A method and apparatus for cleaning the orifice plates (37, 39) of multiple printheads (31, 33) of an ink-jet printer (10). The apparatus includes a multi-blade wiper (60) which is indexed automatically to permit each printhead (31, 33) to be wiped in sequence by a selected blade (61, 63). The desired cleaning is produced by dragging a printhead (31) across the selected wiper blade (61). The wiper mechanism (140) may also comprise a plurality of resilient blades (154, 156) each having an octagonal shape and rotatable about an axis. A cam (180) coupled to the printhead carriage (114) causes simultaneous pivoting of the wiper blades (154, 156) into contact with the printheads (131, 133), as well as rotation of the blades to facilitate cleaning thereof. In the method of this invention, ink is expelled from the printheads to rehydrate dried ink thereon to facilitate its removal.

Abstract: The invention relates to a fluorescent lamp assembly and, in particular, to a fluorescent lamp utilized in a document scanning system which is environmentally and thermally stabilized by means of a bifurcated heater control assembly. A heater blanket is wrapped around the entire surface of the lamp including the end areas surrounding the filaments (66, 68) but exclusive of the aperture through which light is emitted. The size and temperature of the lamp cold spot are selected emperically to maximize output power and minimize illumination transients during power on. The heater jacket has thermostat control set points (82, 84, 86, 88) which, in both the lamp standby and energized states, maintain the blanket and lamp assembly at a constant elevated temperature which is above that achieved by lamp heat alone. Since the temperature distribution is always determined by the blanket and never by the lamp, changes in temperature or temperature distribution (and hence illumination distribution) as the lamp transitions from standby to full on are minimized.

Abstract: A gettering method is proposed for minimizing defects in the shallow junctions used for forming the short channel, including the use of thin dry oxide, a field shaping P⁺- diffusion to enhance breakdown voltage, and TCA (trichloroethane) gettering. Gate-source leakage is reduced with extrinsic gettering on the poly backside, and intrinsic gettering due to the choice of starting material. A submicron channel length (144) is achieved in cells having sharp corners, such as square cells, by blunting the corners of the cells. In this way, the three dimensional diffusion effect is minimized, and punch through is avoided. 
     The method is used to fabricate a double-diffused integrated circuit cell.

Abstract: Disclosed are methods for generating free curves and sculptured surfaces illustratively for use with a CAD/CAM designing apparatus whereby Bezier curves and surfaces are readily generated with reference to point sequences, point groups and surfaces. In operation, a starting point (P0) and an end point (P3) for a sequence of points (q1, q2...) are set as nodes, and a free curve (R(t)) is temporarily established thereby. Then control points are repeatedly established to minimize the shortest distances between the points (q1, q2...) in the sequence and the free curve (R(t)). By use of the coordinates of a plurality of points, the shortest distance (d1, d2...) is found between each of these points (q1, q2...) and a reference patch. The internal control points are set so as to minimize the total sum of these shortest distances. When a patch is generated whose external shape is represented by a plurality of points, with another plurality of points also set on the reference patch for modification, a Bezier surface is generated with respect to these point groups and surfaces.

Abstract: Soil polluted by harmful substances, for decontamination, following a preliminary classification and separation of low density materials and metals, is treated with an extraction medium which causes the pollutants to be dissolved, extracted and/or converted into insoluble substances. For this treatment, pore spaces are first produced in the soil to be treated or existing pore spaces are enlarged, through which pore spaces the extraction medium is passed, the contact times between the soil and the extraction medium being chosen in such a manner that the harmful substances are taken up by this in the course of the diffusion. The soil to be treated is expediently separated into different particle size fractions and these are treated separately from each other. Starting from the finding that the permeation of soil essentially depends on the pore space available, the invention enables pore spaces to be specifically created in such a manner that they can take up a defined volume of the extraction medium which can be transported through them, that is a defined diffusion gradient can be established. As a result it is possible to carry out the extraction in such a manner that - depending on the extraction medium - different harmful substances can be eliminated from the polluted soil as completely as possible in a short time.

Abstract: 5 n7 An image display system includes an input to a source (10, 12, 14) of image pixel data wherein each pixel is expressed as an M-bit value within a non-linear range of values. A first LUT (16) is coupled to an output of the source for converting each M-bit pixel value to an N-bit value within a linear range of values. An image memory, or frame buffer (18), has an input coupled to an output of the first LUT for storing the N-bit pixel values. The system further includes a second LUT (20) coupled to an output of the frame buffer for converting N-bit pixel values output by the frame buffer to P-bit pixel values within a non-linear range of values.

In an exemplary embodiment, the first LUT stores gamma corrected pixel values and the second LUT stores inverse gamma corrected pixel values. Preferably the second LUT stores a plurality of sets of inverse gamma corrected pixel values. Also, the frame buffer stores, for each of the N-bit pixel values, a value that specifies a particular one of the plurality of sets of inverse gamma corrected pixel values for use in converting an associated one of the N-bit pixel values.
