    摘要： A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined. Following use of the composition, the non-used portion of the composition can be disposed of or be reactivated by the addition of a chelating agent.

    摘要： An improved PWM amplifier is disclosed that uses multiple integrators in the loop filter to provide high loop gain across the frequency band-of-interest. The frequency characteristics of the loop filter are optimized to distribute large loop gains across the entire band to provide large suppression of noise and distortions generated in the modulation and output stages.

    摘要： A method and device for displaying animated navigation information has a processor, a memory, a display, and an input, housed in a portable, handheld housing. In various embodiments of the present invention, a plurality of frames are stored in memory, wherein each frame includes data indicative of a still-shot of a portion of an animated sequence represented by the total plurality of frames. The processor retrieves the frames in sequence for display on the display, such that successively displaying each of the frames on the display presents a visualization on the display of animated movement. In one aspect of the invention, animation is provided upon power up of the unit to provide the user with an indication of the nature of use and features of the unit. In another aspect of the invention, animation is provided to provide an indication to the user of satellite signal acquisition for use in navigation purposes. In another aspect of the invention, a graphical menu driven system is provided, such that upon entry of menu selection, a graphical representation indicative of the selection made appears on the display screen. In accordance with another aspect, as the user of the navigation unit moves with the navigation unit on his or her person, the navigation unit tracks the movement and provides an animated, graphical representation indicative of movement of the user.

    摘要： A digital multiplier 110 for multiplying a plurality of multiplicand signals X0-X23 representing a multiplicand and a plurality of multiplier signals Y0-Y23 representing a multiplier. In it, a plurality of intermediate results signals, such as partial product signals, are generated from the multiplicand signals and the multiplier signals. A plurality of adder circuits 40 are also provided for adding the intermediate results signals to generate a plurality of final result signals representing the result of multiplying the multiplicand and the multiplier, wherein at least some of the adder circuits receive first signals representing intermediate addition results from at least two prior adder stages and also receive second signals representing intermediate results generated as the result of only a single addition. Finally, a plurality of delay elements 70 are placed in selected second signal lines so as to delay the arrival of the second signals to the at least some of the adder circuits so as to synchronize the arrival of the inputs to the at least some of the adder circuits.

    摘要： A method of forming a thin film transistor on a substrate including an insulating layer and layers of etchable material over the insulating layer by depositing a layer of photoresist made of polymers that are altered by actinic energy. In the method, an amine cross-linking agent is used with portions of the photoresist. The photoresist is differentially exposed to actinic energy to convert portions of the photoresist and portions are removed. Etching is selectively performed, followed by development of the remaining photoresist, followed by additional etching.
