Abstract: A self-adaptable recharger includes a control circuit connected to a power-supply circuit, a current-sampling circuit and a pulse-based recharge circuit. The control circuit includes a microprocessor. The pulse-based recharge circuit includes parallel recharge branches each under control of a pin of the microprocessor. The microprocessor receives voltage-related and current-related signals from each of the recharge branches and compares the same with basic data stored therein to determine the types of batteries. The microprocessor calculates time-related changes in the voltage-related and current-related signals and a voltage difference between positive and zero pulses to determine the recharge status and correct recharging curves accordingly. The microprocessor determines the highest recharge voltage, a positive slope of voltage, a zero gain of voltage, a negative gain of voltage and a capacity gain to determine an energy level in each of the batteries and stops the recharge when the battery is full.

Abstract: A helical bit tool includes a bit head (1) with multiple helical pieces (2). Each helical piece has a side cutting edge (3) which faces on the direction of cutting operation. The surface of the side cutting edge which faces on the direction of cutting operation forms a cutting face (4). The back surface of the cutting face forms a rear cutting face (5). The step area (7) is formed on the top surface (6) of the bit head, in which forming a step or multiple steps with progressively lower heights from the center of the top surface to the outer flank. The periphery of every step is inclined with respect to the periphery of the bit head. A chamfering surface (9) is formed on where the rear cutting face interfaces with the step area and the top surface of the bit head. An upright cutting face (15) is formed on the side of the chamfering surface near the center of the top surface. The intersection of the chamfering surface, the step area and the top surface of the bit head forms a rear cutting edge (10).

Abstract: A rear-view mirror for a vehicle has a convex reflecting surface composed of a plurality of distinct curved surfaces each having a selected shape that are smoothly joined with each other with a continuously varying average curvature. The average curvature increases gradually along the vertical direction from the top to the bottom of the mirror and along the transverse horizontal direction away from the body of the vehicle. The mirror provides a wide viewing around both sides and of the rear of the vehicle without blind spots and provides a clear image with little distortion that is visually acceptable to a driver.
