Show moreA subharmonic noise reduction circuit having an input terminal and an output terminal. The circuit has a first differential amplifier with a first non-inverting input, a first inverting input and a first output. The overall circuit input terminal is connected to the first non-inverting input. A low-pass filter is connected between the first output and the first inverting input. A second differential amplifier has a second non-inverting input, a second inverting input and a second output. The second output is connected to the overall circuit output terminal. A first resistor is connected between the second output and the second inverting input. A second resistor is connected between the first non-inverting input and the second non-inverting input. The circuit operates at unity gain of the DC voltage component and thus the DC output voltage follows the DC input voltage.

Show moreA method and apparatus for electrostatic spray deposition (ESD) for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate constructed of nickel-YSZ cermet. By reducing the thickness of the electrolyte, and thereby reducing the cell internal IR drop, an intermediate temperature SOFC (ITSOFC) can operate at 600-800.degree. C. A collar positioned at a distance from a discharge end of a spray nozzle enhances a spray pattern of a precursor including the electrolyte material and thus provides a very thin electrolyte layer.

Show moreRe-entry residential communities are an integral part of the criminal justice system. They focus on re-entry prepartion, including job training and drug treatment. These group homes are located in the community where inmates serve a period of time after being released from federal prison, in order to prepare for reentering the community. The inmates are required to go outside during the day to work or participate in community services. Law offenders are housed in penal establishments as a punishment not for punishment. Preservation of personality & prevention of deterioration call for as high a priority as efforts to bring about the inmates’ re-entry into the society. Hence the concept of correction, reformation & rehabilitation of prison inmates should come to the forefront of any community correction center’s adminstration. Show less

Show moreOne embodiment of video transducing system supplies a reproduced video signal with compensated amplitude response so as to exhibit a substantial phase advance for recorded half wavelengths less than the thickness of the magnetizable layer, and a phase correcting network is inserted between the playback winding and the playback amplifier. In a further embodiment, amplitude and phase are partially compensated such that there is a substantial amplitude fall off and a moderate phase advance at the highest frequencies of the useful range, and such that the leading edge of a step function when played back has an overshoot of approximately one to six decibels.

Show moreIn the illustrated embodiment a video cartridge contains an endless loop record tape with a multiplicity of channels, and a pair of pivotal guide arms for holding a length of tape in a taut condition to facilitate loading of the cartridge with the tape threaded between a capstan drive assembly and a transducer head. The downward movement of the cartridge into the operative position serves to retract the tape guides clear of the operating tape path. A tape tension arm is provided along the tape path in the cartridge and is so arranged as to apply tension to the tape as the cartridge is unloaded from the transducing machine. The tape reel in the cartridge is suspended on a bearing ball so as to provide very low resistance to rotation. Sponsorship: IIT Research Institute United States Patent Show less
