Abstract: A modular semiconductor wafer processing system comprises a chamber with a wafer support and gas manifold structure that supplies reactive gases through a showerhead delivery system to one side of a wafer-being-processed and that exhausts both the reactive gases and a non-reactive gas flow. The other side of the wafer is protected from the reactive gases by evenly delivering the non-reactive gases from a platen close to the wafer. The gap between the wafer and platen, and the choice of non-reactive gas and its flow rate are adjusted to optimize the protection afforded to the wafer's one side while still allowing, for example, the stripping of a silicon nitride film from the wafer's other side.

Abstract: First and second independent communication systems are linked across an intersystem interface by a virtual circuit constituted by a land line linking the central stations of both systems. Occasionally both central stations may attempt to simultaneously use the virtual circuit, which cannot be done for digitized speech because in that case the virtual circuit operates as a simplex link. A method of resolving this conflict is disclosed, whereby one of the central stations is issued a token by the other entitling the holder of the token to use the virtual circuit. After the transaction is completed, the token is then returned. Two algorithms are disclosed, one based on the last user of a token giving it to the other user, and the other of which takes into account the number of registered secondary stations in each system.

Abstract: An empty/load valve with a housing from which a reciprocable rod which actuates a changeover spool extends, and a pivotable load measuring arm mounted in offset relation to the axis of the rod and carried by a pivotable shaft. The shaft is mounted on and extends from a rigid cover secured to the housing, and the shaft is interconnected with the rod by a linkage. Most of the shaft, the rod and the linkage are covered by the cover in a dust free manner so as to protect them from dust, etc., of the ambient. Preferably, stops extend from the housing to limit the movement of the arm.

Abstract: A method of, and system for, data transmission over a time division duplex channel in which at least one duplex voice channel constituted by a pair of non-adjacent time slots (or physical channels) in a succession of time frames is allocated for effecting a data transaction between a first and a second station, one of said pair of time slots (or physical channels) being normally designated for unidirectional transmission of data in a first direction between the first and second stations and the other of the pair of time slots (or physical channels) being normally designated for unidirectional transmission of data in a second direction, opposite to the first direction.

Abstract: A novel rubber band powered balloon is presented. No spine, frame, or other support member is used to resist the tension of the rubber band. Instead, the balloon, formed from a substantially non-elastomeric material, is sufficiently rigid when inflated such that supports for the rubber band can be directly connected to the balloon's outer skin. In addition, one embodiment of the present invention includes a novel flapping-vane propulsion system in which the rotational motion of the rubber band is converted into reciprocating motion of the vane.
