Abstract: A gravity power generation device comprises a geothermal well, a hollow heat conducting post, a power generating unit, a steam guiding unit, a condensing unit and a water distribution unit. By discharging and filling the water alternately and repetitively, a first tank and a second tank of the power generating unit can be continuously movable back and forth between a first and a second power generation positions so that a shaft of the power generating unit can continuously rotate to drive a generator of the power generating unit to generate electric power, thereby the heat energy of the geothermal steam can be converted into the potential energy of the water, and then be converted to electric energy so as to meet the demand for power generation by natural energy.

Abstract: A leakage current cut-off device for a ternary content addressable memory is provided. The storage cell of a ternary content addressable memory may be in the active mode, data-retention mode and cut-off mode. This invention applies a multi-mode data retention power gating device to the storage cell of the ternary content addressable memory to reduce the leakage current through the storage cell in the data-retention mode and the cut-off mode, and support the full speed operation in the active mode.

Abstract: A super leakage current cut-off device for a ternary content addressable memory (TCAM) is provided. For various operations of the TCAM, the device uses the high-end and low-end power gating control transistors to turn on/off the don't-care cells to reduce the leakage current passing through the don't-care cells.

Abstract: An electrical connector includes a base plate with an accommodating groove, an integrated circuit board, and a card-ejecting device. The accommodating groove has an open front end and a closed rear end, and is adapted to receive a smart card therein. The smart card has a front end extending from the front end of the groove, and a rear end that is spaced apart from the rear end of the groove at a small distance. When the front end of the smart card is pressed inwardly to move the rear end of the smart card to the rear end of the groove, and is subsequently released, the card-ejecting device pushes the smart card outwardly relative to the connector. Accordingly, the smart card can be ejected with ease.

Abstract: Disclosed is a one-piece hold-down for interconnecting an electrical connector and a printed circuit board, the hold-down having a trunk, a head portion, and a tail portion. The one-piece hold-down is suitable for holding an electrical connector having either a dielectric or a metallic housing to the printed circuit board. After the hold-down is fitted into a locating hole formed on the electrical connector, the head portion of the hold-down is deformed by means of an assembly apparatus so as to latch the electrical connector housing.
