Abstract: This disclosure describes an improved etch selectivity of a-C mask during HAR etch processes by using a cyclic etch process. The process has two principle steps: 1) A partial etch using a polymerizing etching recipe with lower O2 and extra polymer generation where a-C mask selectivity to dielectric (e.g. for SiO2 or ONON layers) is high; and 2) A polymer cleaning step using Kr sputter, Xe sputter, NF3, SF6, IF7, IF5, CF4, or other F based etching process, with or without bias, to etch the polymer. The polymer cleaning step may include addition of O containing molecules such as O2, CO, CO2, NO, NO2, N2O, SO2, and/or COS. These steps are repeated between a partial etch process (polymer creating) and polymer cleaning step (cycle etching).

Abstract: The present invention relates to a solid-state battery that is based on a phthalocyanine solid-state electrolyte/anode connection that is chemically obtained. Such chemical connection process yields a solid electrolyte interphase that connects the solid-state battery's phthalocyanine solid-state electrolyte and anode. Unlike other processes for forming solid-state electrolyte/anode connections, the present chemical process does not require that solid-state electrolyte be ductile and flow under high pressure.

Abstract: A communication system for sending surveillance signals in a hostile environment to an operator. The communication system comprises a plurality of relay sensors to transceive collected data between sequential relay sensors and ultimately to an operator. The communication system has a tractor for dispensing plural relay sensors throughout the hostile environment. The sensors may be dispensed by an elevator to a position where a relay sensor can be retrieved by a drone for placement to maintain line of sight communication. And relay sensors can be dispensed directly from the tractor to the ground or water. Direct dispensing of the relay sensors can occur through a hole in tractor or off a ramp.

Abstract: An apparatus can be arranged and configured so that after a gas turbine is shut down due to a detected condition, a higher autoignition temperature fuel can be utilized to purge a fuel delivery system and facilitate a quicker restart of the turbine. Embodiments can utilize conduits, valves, and a control system for detection of a fault condition warranting a shut down, purging of a lower autoignition temperature fuel via venting and use of a higher autoignition temperature fuel for purging to facilitate subsequent restarting of the turbine. Embodiments can be configured so an inert gas purge is not needed for venting and purging of the fuel delivery system.

Abstract: A set and release retainer valve assembly of an air brake system engages and releases an air brake while retaining a designated pressure within a brake cylinder. The pressure is retained within the brake cylinder to generate a higher brake cylinder pressure on a subsequent brake application and/or prevent movement of the vehicle system after release of the air brake system. The air brake is subsequently re-engaged to re-set the retaining valve assembly and exhaust the designated air pressure out of the brake cylinder, where the air brake of the vehicle system is released to permit the movement of the vehicle system after re-setting the retaining valve assembly.
