A document inverter is disclosed which may be utilized in conjunction with a belt conveyor wherein the document is conveyed along a continuous path before and after being inverted. Means is provided for selectively determining whether the document should be inverted or allowed to continue along the path uninterrupted.

A trinary inverter for a digital logic circuit of the type having relatively positive, negative and zero signal voltage values is implemented with CMOS transistors and has the advantages of low power dissipation and low output impedance in the zero signal state. The inverter comprises first, second and third inverter branches, where each branch is formed of a pair of complementary MOS field effect transistors. The inverted output signals from each branch are used to produce a device output signa...

An inverter transformer is formed of first and second cores arranged to face each other to form a closed magnetic circuit. The first core has a central leg, an outer perimeter wall, and a partition between the central leg and the outer perimeter wall so that a first groove is formed between the central leg and the partition and a second groove is formed between the partition and the outer perimeter wall concentrically with and outside the first groove. A primary winding is disposed in the second...

One embodiment of the present invention includes a vertical inverter. A layer of P-type material is formed on the surface of an N+-type substrate, followed by formation of an N+ layer, a P+ layer, an N- layer, and a P+ layer. (Of course different doping configurations may be used and remain within the scope of the invention). A trench is then etched along one side of the stack thus formed and a connector is formed to the middle P+ and N+ layers. Another trench is then formed where a gate insulat...

An agricultural machine operative to pick up, convey and invert a swatch or windrow of hay for the purpose of accelerating the curing thereof. The machine has a mobile frame which carries at its fore part a swath-straddling pick-up which function to pick up the swath bodily and to convey it rearwardly and then obliquely to the line of advance for return to the ground or stubble as an inverted swath ribbon or mat. The oblique conveyor comprises a plurality of parallel, closely side-by-side belts ...

An inverter apparatus includes at least one MIS transistor (Q1-Q4) connected in series between an input terminal (A, B) for inputting a direct-current voltage and an output terminal (C, D) connected to a load (5), and a circuit (1-4) generating a drive signal of a single frequency to cause the MIS transistor to effect a switching operation. By providing an inductance element (L1-L4) effecting a parallel resonance with an input capacitance of the transistor between a gate and a source of the MIS ...

An inverter transformer is provided which can turn on a plurality of cold cathode fluorescent lamps (CFLs) with a minimized increase in the number of components, thereby reducing costs. The inverter transformer comprises a plurality of bobbins for windings. The plurality of bobbins each having a secondary winding wound thereon and having a bar-shaped inner core inserted therein are connected to one another for integration, and a primary winding is wound in common on the bobbins connected togethe...

Disclosed is an apparatus for inverting a lugged strip to a desired orientation without the necessity of manhandling the strip and potentially damaging the strip or any of the lugs. The apparatus has a semi-circular tube through which the strip travels. Within the tube, to assist the strip, is a conveyor. The conveyor is mounted on the larger diameter side of the semi-circular tube. The strip is moved from an unloader and into an opening of the inverter with the lugs. The strip makes contact wit...

An inverter transformer comprises an insulation bobbin (10) having a spool (12); a primary winding (30); and a secondary winding (4). A plurality of winding grooves (14) are defined by a plurality of flanges (13) provided on the side surface of the spool (12). The primary winding (30) is provided in one (14a) of the winding grooves (14). Another one (14b) of the winding grooves which has no winding provided therein is interposed between the primary winding (30) and the secondary winding (40).

A small-sized highly reliable power inverter comprises switching elements for inverting power by switching, a drive circuit unit for driving the switching elements, smoothing capacitors for smoothing the output of a DC power source to be supplied to the switching elements, an insulated substrate for mounting the switching elements, a drive circuit board for mounting the drive circuit, and a smoothing capacitor substrate for mounting the smoothing capacitors between the insulated substrate and th...
