Abstract: A two-sided POP UP structure is employed to pop up a LCD screen of notebook/tablet PC while releasing. A display panel of a notebook/tablet PC is connected to a mainframe of the notebook/tablet PC via a hinge. The two-sided POP UP structure has a male part and female part. One end of the male part is fixed to the hinge, and the other end is a cylinder with a holding rib. One end of the female part is fixed to the display panel, and the other end is an elastic metal shaped around the cylinder of the male part. The elastic metal is cut to form a rotation slot for the holding rib. When the holding rib interferes with the elastic metal, the elastic metal deforms to allow the LCD screen to pop up more easily.

Abstract: A hinge for a notebook computer in accordance with the present invention comprises a stationary leaf, a rotating leaf and a sleeve. The stationary leaf and the rotating leaf each have an extension, a pintle and a protrusion. The two extensions are adapted to attach to the notebook computer. The two pintles are mounted in the sleeve from opposite ends of the sleeve, and the sleeve is pivoted relative to only one pintle and the another pintle pivots with the sleeve. The pivoting pintle has a longitudinally keyed surface, and the sleeve has a planar key to abut the keyed surface when the monitor is closed against the body. The hinge has simple structure and is conveniently positioned and assembled.

Abstract: A securing device includes a body adapted to securely connect to the primary plate and two arms vertically extending out from two opposite ends of the body. Each of the arms has an assembly hole to adapt to align with opposite ends of a tubular connector of the primary plate so that when the shaft extends into the tubular tube, the two arms are secured to the shaft. When a radial force is acting on the shaft, the force is compromised by the two arms of the securing device such that damping of the screen is minimized.

Abstract: A coaxial cable joint includes a coaxial cable provided with a joint at one end thereof, and the joint further includes an outer tube accommodated around an inner tube having an inner insertion pipe placed therein. The characteristics of the invention are that at a front end of the inner tube is an inner awl bore, and in the outer tube is placed with a leakproof plastic sheath having an outer awl bore at an inner end thereof. The inner tube is pushed into the outer tube in order to slide the outer awl bore of the leakproof plastic sheath into the inner tube and to further compress the leakproof plastic sheath, thereby eliminating a gap between the coaxial cable and the outer tube by inflating the leakproof plastic sheath.
