Abstract: A treadmill includes a front leg frame and a connecting arm. The front leg frame has a front end pivoted to a support base. The connecting arm has a lower end pivoted to the leg frame. An upper end of the connecting arm is connected to a threaded sleeve connected telescopically to a motor-driven screw rod disposed at a top side of a tread base. A hydraulic telescopic unit is pivoted to the leg frame and the support base. When the threaded sleeve is driven by the screw rod, the tread base is inclined. When the tread base is folded upward, it is held in position by the hydraulic telescopic unit which is prevented from moving telescopically by engagement with a latch member. The latch member disengages the telescopic unit through a release member provided on the tread base.

Abstract: The present invention relates to integrated circuits comprising a protective overcoat and thick copper connectors. According to one aspect of the inventions, vias in the protective overcoat are substantially filled with tungsten plugs, or plugs of another metal with a relatively low coefficient of thermal expansion. According to another aspect of the invention, large vias in the protective overcoat are replaced with arrays of smaller vias. The invention reduces the likelihood of device failures during temperature cycling tests. Also, the invention allows for smaller vias in the protective overcoat and removal of interconnect functions to the thick copper layer.
