The invention is directed to self-locking coupling devices which are suitable for connecting conduits, pneumatic line segments, hydraulic line segments, fuel line segments or other fluid line segments tubes, ducts, and the like. The self-locking coupling device consists of a first fitting, a second fitting, and a locking sleeve. The first fitting having a first end connect to a first conduit and a second end for receiving a second fitting attached to a second conduit. The first fitting having a coupling portion and a locking portion. The coupling portion formed with an internal thread section. The locking portion having at least one locking tang attached to the coupling portion and extending to the second end of the first fitting. The at least one locking tang formed with an internal locking shoulder projecting radially inwardly at the second end of the first fitting. The second fitting having a first end and a second end. The second fitting formed with an external thread section adjacent to the first end and an annular ridge projecting radially outward adjacent the second end wherein the engagement of corresponding internal and external thread sections causes the at least one locking tang to bend and flex radially thereby allowing the internal locking shoulder to ride up and over the annular ridge. The locking sleeve mounted about the first fitting and being movable between an unlocked position and a locked position.

A self-locking coupling device for coupling to a fitting having a radially outwardly facing groove using a coupling body with a central bore and an axially extending collar having a throughbore including a spring and actuating pin with a locking tab and further having first and second catches corresponding to and engageable with first and second slots in a rotatable locking ring mounted concentrically about the collar so as to position the locking tab within the throughbore in an unlocked position and within the central bore in a locked position so as to restrict the axial movement of the coupling body relative to the fitting when the groove is radially aligned with the pin.

A V. sub. BB input threshold potential with feedback circuitry is used to stabilize all of the logic inputs on an GaAs IC to ECL compatible levels over a normal temperature range and normal power supply variations. The system called "V. sub. BB -Feedback" uses "zero translation delay" direct Capacitor Diode Fet Logic (CDFL) inputs. This is an extension of the CDFL circuit approach in which the voltage across the input level shift circuitry on all inputs is adjusted to maintain a threshold voltage equal to the dc potential on an "extra" V. sub. BB input in spite of variations of temperature, power supply voltages or processing parameters such as MESFET pinchoff voltage. A dc potential (V. sub. BB) is applied to the "extra" V. sub. BB input, which is an additional input that is essentially identical to the actual logic inputs.
