Abstract: The fault detection system includes at least one valid zero sequence voltage source, either from a local relay or a remote relay on a protected line. Zero sequence current is selected between total (vector sum from both ends of the protected line) measured zero sequence current or calculated zero sequence current. A zero sequence impedance-based calculation is then made and the result is compared against a threshold value to produce a trip decision. The trip decision is then applied through a normal tripping circuit or a slow tripping circuit, depending upon selected circuit conditions, involving the local and remote ends of the line.

Abstract: A desk top sealer includes three compartments for housing a solenoid assembly, a power supply and a circuit board, respectively. A source of air flow flows into an initial compartment and is channeled through apertures in brackets forming the two remaining compartments for cooling purposes and is exhausted from each compartment through a base. The circuit board, upon actuation, provides RF energy to a fixed ceramic/metal jaw to heat and weld plastic tubing clamped to the fixed jaw by a movable jaw at ground potential. The movable jaw is guided during translation by a pair of rods extending from a face plate, which rods also prevent rotation of the movable jaw about its axis of translation to maintain the movable jaw in alignment with the fixed jaw. The movable jaw is relatively massive to serve as a heat sink for the heat of the tubing being welded and includes a substantial surface area to dissipate to the ambient environment any heat buildup that may occur.

Abstract: Full-contact exposure device that allows high adherence of a photo mask with a board. Upon completion of prescribed processing, a controller controls a moving mechanism to move a platen upward, thereby moving the photo mask and a board closer, and to stop at a position where a sealed space is formed between the two. At the same time a controller starts vacuuming by controlling a vacuum pump. By this vacuum pressure in the space between the photo mask and the board becomes negative, and the photo mask bends downward with its center area sagging and contacting the board. The controller controls a cam drive mechanism to rotate cams while vacuuming, allowing the photo mask to gradually make contact with the board from the center area to its periphery while pushing out the air gradually from the center to the periphery, thereby completing full contact with the board.
