Abstract: The present invention relates to an extension structure of flexible substrates with conductive wires thereon. In a first embodiment, three flexible substrates are prepared, each having multiple conductive wires configured on their front surfaces. The third flexible substrate is flipped over, with its conductive wires facing downwards, and bonded across a boundary formed by the first and second flexible substrates. As a result, the corresponding conductive wires between the first and second flexible substrates are electrically coupled with each other through being physically pressed by corresponding conductive wires in the third flexible substrate.

Abstract: A frame member of a circular vibration screener provides an annular vertical frame wall, a joining rim, being provided at two lateral ends of the frame wall respectively and at least a reinforced flange, protruding from the periphery of the frame wall such that the frame member is able to increase strength and rigidity against deformation and for prolonging the life span thereof.
