Abstract: In one embodiment, a static random access memory (SRAM) device is provided. The SRAM device includes a memory cell, a bit line couple to the memory cell, a voltage supply line coupled to the memory cell, a control circuitry. The control circuitry is configured to charge a voltage supply line while the voltage supply line is electrically isolated from a bit line. A portion of the charge is transferred from the voltage supply line to the bit line. The voltage supply line is recharged while the voltage supply line is electrically isolated from the bit line storing the transferred portion of the charge. The memory cell is accessed using the recharge on the voltage supply line.

Abstract: A multi-linkage press contains a power transmission mechanism includes a rotary shaft driven by a power source; at least two eccentric wheel mechanisms including at least two eccentric wheels, each of the eccentric wheels including a crank sliding set to drive a first sliding block connected with a connecting rod; at least two multi-link mechanisms axially connected on the connecting rod and axially connected with two leveraged linkage assemblies; a sliding assembly including a slidable body with at least four longitudinal plungers, the four longitudinal plungers being axially connected with the two leveraged linkage assemblies to drive a slidable body to operate vertically, and between two of the four longitudinal plungers being connected a first connecting pillar, between another two of the four longitudinal plungers being connected a second connecting pillar, between the first connecting pillar and the second connecting pillar being coupled an axial shank.

Abstract: A power charge system is provided for charging a plurality of portable electric devices. Each portable electric device has a charging port for receiving an operating voltage of the portable device. The power charge system includes a plurality of transformers for converting a plurality of different input voltages into a direct current (DC) standard voltage, and a plurality of converters for converting the standard voltage into the operating voltage of the plurality of portable electric devices. When a portable electric device needs to be charged, a converter corresponding to the portable electric device is capable of being electrically connected to any one of the transformers to receive the standard voltage from the transformer so as to charge the portable electric device.

Abstract: A charging system for charging multiple portable devices includes transformers, branch converters and converters. Each transformer is specific to a different power supply. The branch converters and converters, specific to different portable devices, can be connected in such a way to transfer power to the various portable devices. Connections are standardized within the system giving it a modular design.

Abstract: A rinsing apparatus installed in a toilet and controlled to rinse the user's buttocks, including a cartoon-figured main unit installed in the bowl of the toilet and controlled by a control valve therein to let rinsing water/cleaning solution (perfume) pass from a water inlet through water pressure buffering waiter holes to a spray nozzle via a water pipe.
