Inventor: MICKELSEN REID A
IPC: H01L31/04
Filed: 1984-08-16
Granted: 1985-10-09
Abstract: An improved thin-film, large area solar cell, and methods for forming the same, having a relatively high light-to-electrical energy conversion efficiency and characterized in that the cell comprises a p-n type heterojunction formed of: (i) a first semiconductor layer comprising a photovoltaic active material selected from the class of I-III-VI2 chalcopyrite ternary materials which is vacuum deposited in a thin "composition-graded" layer ranging from on the order of about 2.5 microns to about 5.0 microns ( SIMILAR 2.5 mu m to  SIMILAR 5.0 mu m) and wherein the lower region of the photovoltaic active material preferably comprises a low resistivity region of p-type semiconductor material having a superimposed region of relatively high resistivity, transient n-type semiconductor material defining a transient p-n homojunction; and (ii), a second semiconductor layer comprising a low resistivity n-type semiconductor material; wherein interdiffusion (a) between the elemental constituents of the two discrete juxtaposed regions of the first semiconductor layer defining a transient p-n homojunction layer, and (b) between the transient n-type material in the first semiconductor layer and the second n-type semiconductor layer, causes the transient n-type material in the first semiconductor layer to evolve into p-type material, thereby defining a thin layer heterojunction device characterized by the absence of voids, vacancies and nodules which tend to reduce the energy conversion efficiency of the system.

Title: Carbohydrate-metal bicarbonate complexes useful as carborating agents
Inventor: SO REBECCA SUI-CHUN
IPC: A23L2/40
Filed: 1985-11-14
Granted: 1988-07-20
Abstract: Dry, stable carbonating agents comprised of a carbohydrate/metal bicarbonate complex are disclosed. The complex is prepared by reacting a carbohydrate with a metal hydroxide or oxide at a temperature not exceeding 25 DEG C to form a carbohydrate/metal hydroxide adduct to which carbon dioxide is then introduced to form the complex. The complex is then immediately dried, preferably by freezing it to below its eutectic temperature and freeze dried. The carbonating agents are particularly useful as components of dehydrated beverage powders. Upon rehydration, the complex releases carbon dioxide and carbonates the beverage.

Title: Circuit test method and apparatus
Inventor: MCKEON ALICE
IPC: G01R31/3183
Filed: 1990-01-08
Granted: 1993-03-03
Abstract: An analogue circuit or unit under test (34) is tested utilising automatic test equipment (30) and an interface unit (35) to apply stimuli to the circuit (34), the stimuli including supply potentials. A computer (32) analyses the circuit (34) as a network of nodes and modules to deduce a set of ranges of values at selected nodes, the ranges being determined from the set of the stimuli and a resultant set of test measurements, taken from nodes of the circuit by means of the interface (35) and automatic test equipment (30), taking into account tolerances in the stimuli, the measurements and the nominal parameters of components of the circuit. If there is inconsistency among the derived ranges the computer (32) treats as potentially faulty any module which could remove the inconsistency if the constraints imposed by that module were suspended. The computer (32) controls an iterative, hierarchical process involving repetition of the sequence of steps using different sets of stimuli and/or measurements and/or different analyses of the circuit into nodes and modules, in particular with analysis in terms of successively smaller modules. In this way, the location of faults can be progressively narrowed down and corresponding output information can be given in a device (40) such as a VDU or printer.

Title: Subscriber unit for wireless digital subscriber communication system
Inventor: CRITCHLOW DAVID NORTON
IPC: H04B7/00
Filed: 1990-08-01
Granted: 1994-06-29
Abstract: A subscriber unit for wireless communication with a base station in a wireless subscriber communication system includes a FIR chip, a DIF (digital intermediate frequency) chip, a single processor chip and a radio. The processor chip transcodes a digital voice input signal to provide digital input symbols; demodulates an output signal received from the base station to provide digital output symbols; and synthesizes a digital voice output signal from the digital output symbols. The FIR chip FIR filters the digital input symbols and generates timing signals for timing the transcoding and synthesizing operations in the processor chip. The DIF chip digitally synthesizes a digital intermediate frequency signal by direct digital synthesis (DDS) and modulates the digital intermediate frequency signal with the filtered input symbols to provide a modulated intermediate frequency input signal. The radio further processes the modulated input signal for transmission to the base station.

Title: Device for differential vectoral protection against underground outages in a triphased electrical network
Inventor: MORLOTTI GIANMARIO
IPC: H02G/
Filed: 1990-01-31
Granted: 1993-08-18
Abstract: This invention includes a peripheral unit in which the homopolar current (Io") that circulates in the secondary of each toroidal current transformer (TA) placed on each triphased line being protected. For every input and output line into and from a medium power supply there are other reductions by an ampermetric transformer (TA2) that is attached to the secondary through a drag value (R) that supplies power (Vi) proportional to the initial homopolar current and in phase with it. This signal is clean by way of a filter through which the bands pass (f1). The band is tuned to the nominal frequency of the network, which gives an output for a signal (Vf) that is also proportional to the said current and the its phase. This signal is converted into a square wave signal (Sp) with and independent module from the input signal but in phase wit hit. All the signals (Sp) produced by different peripheral units associated with each medium power bar are algebraically summarized in a central unit (UC) by a summarizer (G1 or G2) to which a signal that normalizes the signals is attached. This happens through the said summarizer according to the logic so if the input signal is 0, the output is 0. If the input signal is more or equal to +1, the output is +1 but if the input signal is equal to or less than -1, the output is -1. The normalized signal (Sc) returns to the peripheral unit where another unit (C2) is rotated by 180 degrees and where different means (C3-C4-C5-C6-L1-L2-L3-I1-S2) to measure the phase displacement between the rotated signal (-Sc) and the one (Sp) furnished by the peripheral unit and elaborate a control signal when the phase displacement is less that a preset value, 90 degrees for example. A means (S1) is attached to the output filter where the band (f1) passes, producing a controlled signal when the reported power is higher than the preset value. Other means (L4-t1) control the opening of the interrupter (S) that is governed by the peripheral unit. This unit is only considered when being input. The said means (L4) are the two aforementioned control signals and are used only if they are fixed for greater than a preset interval.
