Abstract: A display device includes the following features. A display panel is disposed in a shell and has a display surface and a back surface. The display surface faces a light-passing portion of the shell, and a first heat dissipation space is formed between the display surface and the light-passing portion. An airflow-blocking plate is disposed in the shell, and a second heat dissipation space is formed among the airflow-blocking plate, the shell and the back surface. A third heat dissipation space is formed between the airflow-blocking plate and the shell. The first heat dissipation space, the second heat dissipation space, the third heat dissipation space, an air inlet and an air outlet of the shell are communicated with each other. A heat-generating assembly is disposed in the second heat dissipation space. A first fan is disposed at the air outlet.

Abstract: The present invention provides a torsion resistant shielded cable which includes at least one conductor; an insulating layer covering outside the conductor; a first isolating layer surrounding the insulating layer; and a shielded layer including a number of wires, single wires or strand wires, wound around the first isolating layer in a clockwise and counter-clockwise alternative order along an axial direction of the conductor to prevent the strand wires from breaking while the torsion resistant shielded cable is twisted.

Abstract: An easily openable can includes a foldable tab having an actuating ring attached on the tab and normally flatly sealing a drinking opening formed on a can cover and operatively openable along a score line along a contour of the tab on the cover, a base folding line concave downwardly and pre-formed in a rear base portion of the tab, and an intermediate folding line convex upwardly and preformed on an intermediate portion of the tab, whereby upon pulling of the actuating ring and the tab to open the drinking opening and then upon folding of the tab along the base folding line and the intermediate folding line, the tab can be folded and retained on a rear opening edge without dropping into a can interior for hygienic purpose and also to allow the actuating ring to conceal a sharp edge of the tab severed from the can cover for safety reason.
