Abstract: A multi-zone audio distribution amplifier system includes positions for several stereo amplifiers which may be used as modular and cascadable amplifier units. The system is enclosed in a housing having a front panel with windows for exposing a set of led display circuits on the front side of the housing and easy access to the modular units on the rear side of the housing. Each modular amplifier unit includes a printed circuit board for an amplification circuit, a heat sink, and a loop-back port for cascading the amplifier units. An interface board includes support for the display and edge-connector receptacles for receiving each printed circuit board edge and for providing power to each of the amplifier units. Each amplifier unit is operable independent of the others, and the desired amplification may be selected by electrically cascading the amplifier units via the loop-back ports.

Abstract: A regenerative RF bi-directional communications system is provided for establishing RF coverage within a RF block tunnel area. The system uses a plurality of cascaded amplifier stages for periodically regenerating signals which are transmitted and received along a series of radiating cable length which link base station transceivers to hand-held or like mobile communication units. An intermediate frequency distribution system is used so that the required level of amplification is achieved through the several cascaded amplifier stages at the level of low-power IF signals generated from the original RF signals in conjunction with the appropriate oscillator and pilot signals. The IF distribution system restricts the cascading effect occurring due to the plurality of cascaded amplifier stages on the relatively low-power IF signals, thereby producing a negligible amount of intermodulation.

Abstract: An apparatus in which a donor roll advances toner to an electrostatic latent image recorded on a photoconductive member. A plurality of electrical conductors are located in grooves in the donor roll. The electrical conductors are spaced from one another and adapted to be electrically biased in the development zone to detach toner from the donor roll so as to form a toner cloud in the development zone. In the development zone, toner is attracted from the toner cloud to the latent image. In this way, the latent image is developed with toner.

Abstract: A Field Effect Transistor (FET) device especially useful in common gate amplifiers of signals in the microwave to millimeter range. The device's input and output are impedence matched to preclude phase cancellation and form a traveling wave amplifier capable of high voltage operation. The channel is formed of gallium arsenide separated from the gate by a layer of aluminum arsenide heteroepitaxial with gallium arsenide layer. The channel is bounded by heavily doped regions which act as inherent sources and drains, and limit electric field strength to avoid sluggish response of heavy mass carriers. The gates are formed by etching trenches in a semi-insulating gallium arsenide layer on the opposite side of the aluminum arsenide layer from the channel, using the aluminum arsenide as an etch stop, oxidizing the exposed aluminum arsenide, and epitaxially growing gallium arsenide to narrow the trench.

Abstract: A sheet of glass or similar material is moved to and in the cutting area of the apparatus by sheet gripping assemblies that engage and grip an edge portion of the sheet, and that undergo precise controlled movement. A fluid-jet discharging nozzle moves above the sheet along a path of travel normal to the sheet movement. Belts supportively underlying the sheet are driven sufficiently in unison therewith to minimize possible scratching or other marring of the glass. To the same end, the lower portion of the fluid-jet nozzle is of tapered shape. Sheet-engaging clamps of the gripping assemblies are moveable in a manner adapted to prevent damage to the glass sheets engaged thereby. Positioning structure may be provided for receiving and positioning the glass sheets preparatory to the cutting thereof.
