    摘要: It is aimed at stably implementing a protection function of a secondary battery mainly under software control and providing a battery pack characterized by a reduced circuit installation area, parts costs, and power consumption. An AD converter outputs a voltage value between a positive electrode and a negative electrode of a secondary battery. Based on the voltage value, a microcontroller determines a state of the secondary battery out of overcharge, normal operation, and over-discharge states. According to the determined state, the microcontroller controls operations of a discharge current cutoff means and a charge current cutoff means via a FET driver. When it is determined that the secondary battery is placed in an overcurrent state based on the charge and discharge current size of the secondary battery, an overcurrent detection circuit enables the discharge current cutoff means to be a cutoff state in preference to control by the microcontroller.

The pair of sun gears are coaxial with a rotational axis of the housing. End portions of a pair of drive shafts extending through a pair of end walls of the housing are spline-engaged respectively with the pair of sun gears. The pair of sun gears have helical teeth, respectively. Each pair of intermeshing planetary gears are meshed respectively with the helical teeth of the pair of sun gears, respectively. A plurality of washers are interposed between the pair of sun gears. The plurality of washers have first washers and second washers, respectively, which first and second washers are alternately arranged. The first washers are engaged with end portions of reduced diameters of the sun gears such that the first washers are capable of moving axially but incapable of rotation. The second washers are engaged with the housing such that the second washers are capable of moving axially but incapable of rotation.

    摘要: An apparatus for controlling an opening angle of a throttle valve in an internal combustion engine. When an accelerator pedal is depressed by a vehicular driver, an accelerator drum attached onto an end wall of a main body of a single motor is rotated via an accelerator wire and the main body of the motor, a drive axle of the motor held with respect to the main body of the motor, and a rotation axle of the throttle valve are integrally rotated. When control is transferred from the above-described ordinary opening angle control state into a traction control state, the hold function of the motor is released and the motor is driven so as to reduce the opening angle of the throttle valve. It is possible to drive the motor so as to control the opening angle of the throttle valve, with the accelerator pedal released, to achieve an automatic cruise speed control and to drive the motor according to an accelerator pedal operating variable so that an arbitrary characteristic of the throttle valve opening angle control can be acheived.
