Abstract: ABSTRACT    An apparatus for producing improved large area photovoltaic devices by substantially reduc-ing the warpage of relatively  large area, rela-tively thin webs of magnetic substrate material which travel through a plurality of high tempera-ture, low pressure glow discharge deposition cham-bers.  As the web of the substrate material moves through the deposition chambers, it assumes A normal, elongated path of travel.  Due to the elevated deposition temperature; the elongated path of travel, the force of gravity, etc., the web has a tendency to warp.  Warpage of the web is undesirable as it promotes the deposition of non-uniform semiconductor alloy layers.  The improve-ment of the present invention contemplates the establishment of at least one magnetic field with-in each deposition chamber which is adapted to urge the web of substrate material out of its normal path of travel into a flat, substantially planar path of travel.  The new flat path of trav-el serves to substantially reduce warpage of the web which permits uniform amorphous semiconductor alloy layers to be deposited.  In alternate em-bodiments, the web of substrate material may be urged into sliding contact with a plurality of stationary ceramic magnets or the web may be urged into rolling contact with a plurality of rotatable magnetic elements which may either be hollow, ceramic magnets or electromagnets.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a power grid network com-prising two or more induction generator systems, each system including a switched capacitor controlled induction generator adapted to provide power at a regulated voltage and frequency. Each induction generator system includes an n-phase induction machine having a rotatable input shaft and at least n output lines.  The input shaft is driven at a controlled frequency by a prime mover.  An N-stage, switched capacitor array provides a controlled reactive current to the output lines of the induction machine.  Each stage of the array includes a capacitor network associated with each of the permutations of pairs of the n output lines.  The capacitor networks for each stage are characterized by substantially the same capacitance.  Each stage further includes an associated switch network associated with each capacitor network for selectively coupling the capacitor network across its associated pair of output lines.  A feedback network is coupled between the output lines and the capacitor array to adaptively control the switching of the various N-stages in and out of operation.  In grid-connected operation, the feedback network includes a power factor detector for producing a signal representative of the power factor at the output lines of the induction machine.  The feedback network uses this power factor signal to control the switched capacitor array to adaptively vary that net capacitance across the output lines of the induction generator so that the generator maintains a predetermined voltage at loads coupled to the output terminals.

Abstract: A METHOD OF MANUFACTURING GaAs SEMICONDUCTOR DEVICE     ABSTRACT OF THE DISCLOSURE      Amethod of manufacturing a GaAs semiconductor device of an E/D construction having a GaAs/AlGaAS heterojunction and utilizing two-dimensional electron gas, comprising the steps of forming a heterojunction semiconductor substrate and etching a portion of the substrate to provide a gate portion of a depletion-mode FET.  When the substrate comprising a semi-insulating GaAs layer, an undoped GaAs, an N-type AlGaAs layer of an electron-supply layer, and a GaAs layer is formed, the GaAs layer is composed of a first GaAs layer, an etching stoppable AlGaAs layer, and a second GaAs layer, the first GaAs layer being formed on the N type GaAs layer.  The etching for provision of the gate portion is carried out by a dry etching method using an etchant of CCl2F2 gas, so that the second GaAs layer can be etched but the AlGaAs layer cannot be etched. Thus, the thickness of the layers between a gate electrode of the depletion-mode FET and the GaAs/AlGaAs heterojunction plane is determined at the formation of the hetero-junction substrate, consequently a better uniformity of the threshold voltage of depletion-mode FET's is obtained.

Abstract: METHOD FOR PRODUCING A RECOMBINANT                BACULOVIRUS EXPRESSION VECTOR                            ABSTRACT      A method for producing a recombinant baculovirus expression vector, capable of expressing a selected gene in a host insect cell, is disclosed.  The method involves cleaving baculovirus DNA to produce a DNA fragment comprising a polyhedrin gene or portion thereof, including a polyhedrin promoter.  A recombinant transfer vector is prepared by inserting said DNA fragment into a cloning vehicle and thereafter inserting a selected gene into the thus modified cloning vehicle such that it is under the transcriptional control of the polyhedrin promoter.  The recombinant transfer fector is contacted with a baculo-virus DNA so as to effect recombination and incorporation of the selected gene into the baculovirus genome.  The resultant recombinant baculovirus is then used to infect susceptible insects or cultured insect cells and the protein product from the incorporated selected gene is produced from the infection.
