Abstract: A leakage control circuit and DRAM equipped therewith. The leakage control circuit includes a differential amplifier, a first voltage divider, a second voltage divider, MOS transistors, and a charge pump. The first voltage generates a first reference voltage. The second voltage divider generates a second reference voltage. The differential amplifier has a first input receiving the first reference voltage, a second input receiving the second reference voltage, and an output coupled to the input of the charge pump. MOS transistors have drains coupled to the first input of the differential amplifier, gates coupled to the output of the charge pump, and sources coupled to a ground potential.

Abstract: A process for fabricating a heat sink with high-density parallel fins is provided. The process includes steps of providing a metal block including a first base and a second base, the first base being rectangular-solid shaped, the second base being rhombus-shaped and disposed over the first base wherein the second base includes a first edge surface and a second edge surface inclined at a specific angle, cutting the second base from a position on the top surface of the second base and parallel with the first edge surface until the first base is reached, thereby forming an inclined sheet, adjusting the inclined sheet to be normal to the top surface of the first base, thereby forming a fin, and repeating the cutting step and the adjusting step to produce the heat sink with high-density parallel fins.

Abstract: A structure of a water-hose retracting device is disclosed. The structure a hose retracting frame, a covering plate, an axial tube module, a hose accessing frame and a rotating reel, and in combination with a ratchet wheel and an urging block, characterized in that the axial tube module is positioned at the hose retracting frame, and the interior of the hose body is engaged with the rotating reel which can be tightened by rotating, thereby by means of the urging block with the ratchet wheel, an appropriate length of the hose can be accessed.

Abstract: A method for determining a plurality of fluid flow characteristic curves of a heat-dissipating system, wherein each fluid flow characteristic curve is a relationship curve of one of an air pressure and an air flow and the air pressure and a rotating speed of the heat-dissipating system.
