Abstract: A foldable electronic device includes first and second members interconnected pivotally by a coupling unit. The first and second members have first and second positioning portions, respectively. The coupling unit includes a coupling link, a slide link and a biasing member. The coupling link has a first end portion retained rotatably at the first positioning portion, and an opposite second end portion extending in a longitudinal direction. The slide link is retained slidably on the coupling link for sliding along the longitudinal direction, and is retained rotatably at the second positioning portion. The biasing member pulls the slide link toward the first member. The coupling unit permits movement of the second member in sequence from an unfolded position, a first intermediate position, a second intermediate position, and to a folded position relative to the first member.

Abstract: An earphone jack includes an insulative housing and conductive first, second and third contact members. The insulative housing has opposite front and rear ends, and is formed with a plug insertion hole that extends from the front end to the rear end.

Abstract: A method of forming a silicon nitride-silicon dioxide composite insulator layer for use as a gate insulator stack for an MOSFET device, has been developed. The method features formation of the silicon dioxide component of the gate insulator stack, after formation of the overlying silicon nitride component, allowing the gate insulator stack to be comprised with a nitrogen profile presenting enhanced barrier characteristic and less interface charge than counterpart silicon nitride-silicon dioxide composites formed wherein the silicon nitride component was deposited on an already grown underlying silicon dioxide layer. Oxygen ions, or oxygen radicals obtained via ultra-violet procedures, penetrate the silicon nitride component and locate in a top portion of the semiconductor substrate. Subsequent annealing allows reaction of the oxygen ions or radicals with a top portion of the semiconductor substrate resulting in the desired silicon dioxide component underlying silicon nitride.

Abstract: An electrical socket includes a socket body, a central terminal pin, and a curved spring terminal piece. The socket body includes a bottom surface with a dovetail groove, which has a rear end retaining portion that is adapted to receive an engaging end portion of a hollow plug fittingly therein, and a protrusion adapted to engage an annular groove in the plug. The central terminal pin is adapted to be inserted into the plug for electrical connection therewith. The spring terminal piece has a movable portion that is adapted to engage the groove in the plug so as to press the plug against the protrusion such that the plug is clamped between the protrusion and the terminal pin, thereby forming electrical connection with the plug when the plug is inserted into the socket body.
