A socket connector for connecting a post or ball wherein the female element grips the post with resilient prongs with end tips at low insertion force but positive contact is maintained and wherein attempted withdrawal is normally inhibited by increasing force applied to the post by the female element in response to the withdrawal force. The female element comprises a tube of resilient conductive material that has been sliced or helically partitioned into opposing helical prongs so as to allow the prongs of the connector to spirally open around the post or ball-like bump and mechanically grip the post or bump as the post or bump is inserted along the longitudinal axis of the tube. The tubular element may be made by forming helical prongs in the end of a tube in helical cuts from about a mid section to one end of the tube.

A ground fault protection device includes an electrically-conductive main body having downwardly-extending, ground-penetrating electrodes configured for minimal ground penetration. The device has one or more grounding terminals for connection of grounding cables, and may have handles for manual transportation. The device may be installed at a desired field location by applying downward force to the device to press the electrodes into the earth, thereby establishing an electrical connection between the grounding terminals and the ground via the main body and the electrodes. Grounding cables may then be connected between the grounding terminals and structures or equipment requiring grounding. Optionally, the main body may define a reservoir having a plurality of drainage ports. The reservoir may be filled with water, which will drip through the drainage ports and moisten the soil surrounding the electrodes, thereby decreasing the soil's electrical resistance and improving electrical conductivity between the electrodes and the soil.

An improved high gloss ink for use in children's writing instruments is described. The improved high gloss ink avoids the use of metal-containing pigments and their relatively high costs.

A rapid thermal nitridation (RTN) process produces a nitrogen concentration gradient in an oxynitride layer to compensate for transistor threshold voltage effects from a thickness gradient in the oxynitride layer. The nitrogen concentration gradient is selected to allow greater dopant penetration through thicker gate dielectrics in PMOS transistors formed using the oxynitride layer. Any increases in threshold voltage due to thicker gate dielectrics are counteracted by corresponding decreases in threshold voltage due to dopant penetration, allowing consistent threshold voltage values to be maintained for all PMOS transistors on a single wafer. The nitrogen concentration gradient can be introduced by regulating the flow of nitrous oxide during RTN processing to cause an accumulation of atomic oxygen to develop within the process chamber. The atomic oxygen forms a concentration distribution that increases in the direction of nitrous oxide flow, and therefore removes incorporated nitrogen from the oxynitride layer in corresponding proportions.
