Patent EP-0453641-A2 (EP)
Inventor: KUENEMUND RONALD DIPL-ING
IPC: G06F7/544
Filed: 1990-12-04
Abstract: The invention relates to a CORDIC processor with a carry-save architecture with intensive pipelining for vector rotations, particularly for problems of real-time processing. The circuit according to the invention consists of a multiplicity of vector iteration stages IXY and angle iteration stages IZ, some of which exist in duplicate (for example IXY 1a, IXY 1b) in order to ensure a convergence of the CORDIC algorithm in spite of an uncertainty range U in the sign detection of carry-save numbers, and in order to simplify other circuit sections, for example a multiplier MULK. Due to the carry-save architecture, only incomplete addition/subtraction operations are executed in the iteration stages IXY, IZ and subtotals are carried in the form of carry and save words along separate paths through the CORDIC processor until they are added together to form the final result vector X'N, Y'N in an adder VMA at the processor output. The advantages of the invention consist of a low chip area requirement which results from a high regularity of the overall structure and from using basic cells of simple configuration, and the very high processing speed which is the result of joining intensive pipelining and the carry-save architecture.

Abstract: A system comprises a shallow container (11 a-11 d) and a load (10) located therein for heating by microwave energy. The system is designed either to be used with, or itself to incorporate, a structure for generating or enhancing at least one mode of the microwave energy of an order higher than a fundamental mode, the latter being determined by boundary conditions resulting from the lateral dimensions of either the container or the load or both. The invention resides in controlling the depth (d) of the load in the container in such a manner that, upon irradiation of the product with the microwave energy, the power absorbed by the load from a higher order mode is at or near a maximum value, while preferably the power absorbed by the load from the fundamental mode is at or near a minimum value. Since uneven heating would ordinarily be associated with the predominance of a fundamental mode, the result of this invention is to increase the intensity of a higher order mode relative to the fundamental mode intensity, and thus provide improved uniformity of microwave heating.

Inventor: PRITCHETT SAMUEL D
IPC: H01L21/8232
Filed: 1990-06-25
Abstract: A quasi-interdigitated transistor (50) for rf power applications has a plurality of channel regions (102-118) that are each offset from each other in a y-direction such that a  q   x  heating component from adjacent channel regions will affect any one channel region to a lesser extent than the  q   x  from adjacent channel regions in the conventional interdigitated structure. In a preferred embodiment, the channel regions (102-118) are formed in a single, curved, V-shaped row such that the cumulative transverse width of all of the transistor sections is less than the waveguide cutoff frequency. The V-shaped row of transistor sections also provides the advantage of parallel signal paths having approximately the same propagation time delay such that there is no phase cancellation within the device.

Abstract: In an image pickup system which is used on a craft flying over an object zone and comprises a first (photoelectric) transducer (21) for producing a first partial (electric) signal representative of a partial image of a partial zone lying forwardly of the craft flying at a first position and a second transducer (22) for producing a second partial signal representative of another partial image of the partial zone lying directly under the craft flying, an interval of time later, at a second position spaced from the first position by a distance between two partial zones packed up by the first and the second transducers when the craft is at the first position, a compression unit (90) compresses the first and the second partial signals into first and second compressed signals. A delay circuit (54-1) gives the first compressed signal a delay equal to the interval of time and produces a delayed signal. A subtracter (55-1) calculates a difference between the delayed signal and the second compressed signal and produces a difference signal. The first compressed signal and the difference signal are transmitted by a transmitter to a ground station to obtain a stereo image of the object zone. Preferably, the image pickup system should comprise a third transducer (23), another delay circuit (54-2), and another subtracter (55-2). The delay circuit is implemented by a memory.

Abstract: An optically switchable device (1) has a heterostructure (2) defining a first potential well (3) separated by a barrier layer (4) from a second potential well (5) which provides an electron energy level (e₅) which is lower in electron energy than the lowest electron energy level (e₃) of the first potential well (3). The barrier layer (4) provides an intermediate electron energy level (e₄) and is sufficiently thick to inhibit tunnelling of holes from the first (3) to the second (5) potential well. The barrier layer (4) thus confines holes of electron-hole pairs generated in the first potential well (3) by an incident optical beam to the first potential well (3) whilst facilitating transfer of the electrons from the first potential well (3) to the second potential well (5) via the intermediate electron energy level (e₄) provided by the barrier layer (4).

Abstract: An image interface device connected to a so-called digital copying machine for inputting from and outputting to an external unit, such as a computer system or a communication unit, both multilevel and binary image data. The digital copying machine performs various image processings on the image data output from a scanner for photoelectrically reading an image using a CCD or the like and supplies the processed image data to a printer, such as an ink jet printer, for printing. When the image data is input from the digital copying machine, the multilevel or binary data combined by a multilevel and binary data separating/combining circuit is input through the same data bus controlled by an I/F control circuit. When the multilevel or binary image data is output to the digital copying machine, the multilevel or binary data is output through the same data bus, as in the case of inputting the image data. That is, when the multilevel image data is output, it is sent from the I/F control circuit to the multilevel and binary data separating/combining circuit and is output as the multilevel image data. When the binary image data is output, it is output from the multilevel and binary data separating/combining circuit as the binary image data.

Abstract: The invention relates to a system for separating components of the bulk material of different hardness values, in particular refuse, and consists of a drum 2 which rotates about a horizontal axis 3 and of a charging plate 5 which is arranged above said drum 2 and from which the components of the bulk material pass, after impact, onto the upwardly moving side of the drum, soft parts being entrained from the drum away over the said side onto the downwardly moving side of the drum and hard parts dropping downwards onto the upwardly moving side. The innovation is that the charging plate 5 has a rough surface which ensures that parts which have stuck together or are connected in any other way are separated from one another on impact. Furthermore, a blocking plate 18 is provided above the rising side of the drum, which plate collects soft components of the bulk material which slide too far when rebounding from the charging plate and directs them onto the drum at a point from which the soft components continue to be entrained upwards.

Abstract: Environmentally friendly, disposable, degradable and/or recyclable plastic articles, which take the place of environmentally unfriendly styrofoam, are molded from synthetic resin blends comprised of 65% to 95% of water soluble thermoplastic resin having an inverse solubility characteristic and about 35% to 5% of resins and fillers that are functionally compatible with the water soluble resin. The articles are insoluble when they contain a hot beverage or food but become soluble when exposed to tepid or cool water. 
The inversely soluble resin may be high molecular weight poly(ethylene oxide) or hydroxypropylcellulose, and mixtures thereof. By appropriate selection of the compatible resin and the ratio of the compatible resin to the inversely soluble resin, solubility time may be varied from minutes to weeks. The articles can be dissolved in water or by the moisture in a landfill, or can be recycled by dissolution in cool water, thereby eliminating the trash and garbage problems inherent in the use of nondegradable styrofoam.
