Abstract: A face of a diamond body (10, FIG. 1 ; 30, FIG. 2), such as a CVD diamond film, is etched by maintaining, for a prescribed time duration, at least a portion of the face in direct physical contact with a layer (11) comprising a molten or a partially molten metal or a metallic alloy of one or more than one rare earth metal, the layer having the property of dissolving carbon. While the body is being etched, various portions (31, 32, 33) of a major surface of the body can be protected for various time durations by masks against the etching--whereby, after dicing the body, each of the resulting dies can be used, for example, as a submount (30) for a laser (40) and a photodetector (61)--the latter for the purpose of feedback to the laser.

Abstract: The specification describes method and an apparatus for separating different components of liquid mixture in a separation chamber (120). The separation is performed by admitting the liquid mixture into the separation chamber (120), the separation chamber (120) having confronting surfaces spaced more closely than the respective lengths of the confronting surfaces. An electric field is then impressed toward at least one of the confronting surfaces of the separation chamber for separating the different the liquid components according to their relative influenceability to the electric field. The separated liquid components of the same influenceability are then mechanically moved in streams each of unlike net influenceability near each other transversely to the electric field, the streams being in communication parallel to the separation influence, so as to transfer a portion of at least one of the liquid components to another of the respective streams by virtue of the continued action of the electric field as the streams progress transversely to the electric field. Finally, the separated steams are removed from the separation chamber (120).

Abstract: A system for providing advance warning of underwater navigation hazards that threaten safe ship passage includes a sonar transmitter/receiver (16) adapted for mounting on the ship in a forward looking direction. A processor (24), in response to sonar returns produced by the sonar transmitter/receiver (16), produces a sonar produced slope profile (49) of a region of the sea bottom in front of the path of the vessel. A memory (44) stores a slope profile (52) of the region of the sea bottom in front of the vessel, such profile being developed from chartered depth data. The stored charted depth data developed slope profile (52) is compared with the sonar return produced slope profile (49) to determine whether the sonar produced slope profile and the chartered depth data slope profile are consistent with each other. If the sonar return produced slope profile in a region of the sea bottom is greater that a predetermined threshold level (selected to identify a potential forward undersea hazard) and the chartered depth data generated profile of such region does not indicate this potential hazard, an anomaly is identified and a signal indicating such anomaly is produced.

Abstract: We have recognized that in the prior art, to insure that there is at least some communication between the calling (101) and called parties (125), when the called party is unavailable to take a call, the calling party (101) may be connected to an alternate destination, e.g., a voice messaging system (141), and the caller's telephone call is considered completed. If the called party (125) thereafter becomes available, the called party (125) is not connected to the caller's telephone call. However, in the invention, this problem is overcome by, in response to receipt of an indication that the called party (125) is available for a caller's telephone call after the caller's telephone call has already been connected to an alternate destination (e.g. 141 or 143), a) disconnecting the caller's telephone call from the alternate destination (141,143) and, instead, b) connecting it to the called party (125), thus interrupting the connection between the caller and the alternate destination. Optionally, a tone or announcement may be supplied to the caller (101) to indicate that the called party (125) will now be connected "live" to the caller.

Abstract: A low-cost battery charge indicator is provided which is capable of indicating a quantity of charge upon a battery or battery pack. The charge indicator includes positive and negative battery terminals and a charge gauge circuit mounted within a battery pack or a battery-powered electronic device. The positive and negative terminals are adapted to receive a battery and to test the battery charge within the battery during times in which the charge gauge circuit is active. Activation of the charge gauge circuit occurs by depressing a momentary switch coupled between the charge gauge circuit and the battery terminals. Upon activation of the switch, one of three LEDs will emit light informing the user of the state of charge upon the battery or battery pack. The switch remains normally open to avoid current draw from the battery during non-test times.

Abstract: A single-port network node transceiver that does not draw any substantial current from the network when it is powered-down, enabling it to meet the ISDN powered-down loading specification when built on a CMOS integrated circuit chip. The pull-up transistors of the transmitter output circuit each have means for shorting the well terminal to source terminal connection when the circuit is operating and opening the connection when the power to the transceiver is shut down. The opening of this connection prevents the well-substrate junction of the pull-up transistors from becoming forward biased and drawing current from the network when the power to the transceiver is off and there is voltage present on the network. The transceiver also includes a plurality of ESD overvoltage protection diodes in series between the power supply rail and each input/output terminal. Since multiple diodes are connected in series and their voltage drops are added together, the diodes also do not draw current from the network when the transceiver is powered down.

Abstract: A back end of the line dry etch method is disclosed. Etching of a mask oxide and temporary (sacrificial) silicon mandrel occurs following the formation of gate stacks and tungsten studs. The mask oxide is etched selectively to tungsten and silicon through the use of a polymerizing oxide etch. The silicon is etched selectively to both silicon nitride, silicon oxide, and tungsten. The process removes the silicon mandrel and associated silicon residual stringers by removing backside helium cooling, while using HBr as the single species etchant, and by adjusting the duration, the pressure, and the electrode gaps during the silicon etch process. The silicon may be undoped polysilicon, doped polysilicon, or single crystal silicon.

Abstract: To determine the total organic carbon content of a flowing liquid in a continuous process, water and oxidizing agents enter lower ports in a multi-stage column and flow upwardly through residence chambers as they are mixed. Spaced apart along the upper path of the liquid, there are helical reaction grooves relatively shallow and containing at least one helical groove to cause rapid motion of the liquid. An ultraviolet lamp extends downwardly through the center of the column so that the outer confining surface of the helical grooves is the outer surface of the ultraviolet lamp, causing the liquid to move rapidly in intimate contact with the ultraviolet lamp to receive intense radiation. The stages are separate and interchangeable so that selected sizes may interconnect. The residence chambers may have different sizes to permit different lengths of residence time and thus permit tailoring of the reaction to the expected organic carbon content and possible side reactions with other impurities in the water.
