    摘要： A circuit for controlling power consumption of a load, by controlling the flow of current thereto, utilizes at least one parallel combination of non-linear resistance elements, such as a varistor and the like, and a gateable semiconductor switching device, such as a triac and the like, to substantially reduce or prevent current flow when the semiconductor switching device is gated to an "off" condition and to enable normal current flow to a load when the semiconductor switching device is gated to an "on" condition. Embodiments of the power circuits for control of magnetron power, in a microwave oven, are illustrated.

    摘要： A method is provided for the manufacture of precision electronic components such as resistors, inductors, and capacitors on a polymer or ceramic surface. The electronic components can be deposited and trimmed to precise or matched values without having precise depositions of all of the pre-patterned materials. Thin film electronic components are deposited on a surface, parameter values are measured or estimated, a correction offset file is generated, and the components are trimmed using adaptive lithography to a very close tolerance. A computer program can be used to enable the adjustment of electronic components by techniques such as changing the physical length of an inductor coil or resistor lead, or by changing a capacitor plate area.

    摘要： A speed regulator digital speed controller for rotating machinery is comprised of a single-chip microcontroller operating in conjunction with a multiple counter/time peripheral, and is programmed in a high level language. Pulses are generated by a digital speed sensor at a rate too low to give the required speed resolution; these pulses are counted and a preset number toggles a binary gate signal. Two clock counters both having an input connected to a high reference frequency oscillator are gated alternately and accumulate a count depending on the length of the gated on interval. These speed related counts are read during alternating gated off intervals into the microcontroller where the speed error is calculated in real time to a high degree of accuracy and resolution. The speed of an electric motor and a steam turbine, for instance, are regulated.

    摘要： A controller for interfacing a single-chip microcomputer with external dynamic random-access memory, includes a subcircuit for generating a column-address strobe at a time after a row-address strobe is generated, and also includes a multiplexing subcircuit for providing the proper 8-bit portion of a 16-bit address output from the microprocessor to the 8-bit dynamic memory inputs, prior to receipt of the associated row-address or column-address strobe. The microprocessor utilizes the strobe-generation and multiplexing subcircuits to burst-refresh the dynamic memory, in one presently preferred embodiment. In another presently preferred embodiment, lines from an additional microprocessor output port are utilized with a resettable binary counter and a multiplicity of buffers, to count through the range of row addresses in cyclic fashion, with each address being incremented after the previously-addressed row of memory cells has been refreshed.
