摘要： A brake control system displaces a primary piston by controlling an operation of the electric motor by a master pressure control unit according to the operation amount (Xop) of the brake pedal, thereby generating a hydraulic pressure in the master cylinder to supply it to wheel cylinders (Ba to Bd). The master pressure control unit sets a target relative displacement (ΔXT) between an input piston and the primary piston and a target hydraulic pressure (PT) in the master cylinder, and appropriately switch which is used to control a brake force. During regenerative cooperation, the master pressure control unit selects the control with use of the target hydraulic pressure, which enables easy execution of a hydraulic pressure control including a subtraction of the hydraulic pressure corresponding to a brake effect from the regenerative cooperation.

摘要： To obviate the necessity of a plier or other tool for extracting a driver bit from a screwdriver, and prevent an adjustment sleeve detached from the screwdriver from being lost. The stop ring has an oval dusting opening having a width wider than the distance between the opposite sides of the hexagonal cross section of the driver bit and narrower than the diagonal length of the cross section. After detaching the adjustment sleeve from the screwdriver, the parallel sizes of the oval dusting opening of the stop ring are aligned with the opposite sides of the driver bit, and the stop ring is moved toward the driver bit, until a peripheral groove portion of the driver bit reaches the edge surrounding the dusting opening. By changing the relative angle between the adjustment sleeve and the driver bit, the diagonal part of the driver bit is caught by the edge surrounding the oval dusting opening. Subsequently, by pulling the adjustment sleeve with the stop ring attached thereto, the driver bit can be extracted from the screwdriver against the urging force of a steel ball provided on the screwdriver.

摘要： An electric motor is controlled based on an operation of a brake pedal to move a primary piston forward through a ball screw mechanism, thereby generating a hydraulic pressure in a master cylinder. At this time, a reaction force from the hydraulic pressure in the master cylinder is fed back to the brake pedal through an input piston. Automatic brake control, which generates the hydraulic pressure by driving the electric motor regardless of whether there is the operation of the brake pedal, is carried out. During the automatic brake control, an actual relative position is compared with a determination threshold value set based on the relative position between the primary piston and the input piston which is generated by a movement of the primary piston, and it is determined that the brake pedal is operated in a case where the relative position is smaller than the determination threshold value.

摘要： There is provided a brake system that can generate a desired braking force in a nondefective system even if at least a secondary side system of a tandem master cylinder is defective. When the secondary side system is defective, a primary piston (assist member) is moved by a larger amount than an amount of movement of an input piston (input member). Pressure in the nondefective primary side system is increased, and this can compensate for a braking force for two wheels on the primary side, which may be reduced by the defect in the secondary side if no measure is taken, and allows a desired braking force to be generated. Further, the pressure in the primary side system is increased to apply hydraulic pressure reaction to the input piston and an input rod (input member), thereby achieving good pedal feeling.

摘要： It is an object of the invention to provide an effective technique for reducing wear of sliding contact areas in an engagement clutch of a rotary tool. According to the invention, a representative rotary tool may comprise a motor, a tool bit, a driving-side clutch element, a driven-side clutch element, a biasing spring, a rotation preventing member and an enclosure. The biasing spring biases the driven-side clutch element toward the power transmission prevented position. The biasing spring is disposed in a compressed state on the outer peripheral side of the driving-side clutch element and the driven-side clutch element and extends between the driving-side clutch element and the driven-side clutch element. At least part of the biasing spring is enclosed by the enclosure. Lubricant deposited on the inner wall surface of the enclosure is supplied to either a sliding contact area between the biasing spring and the driving-side clutch element or a sliding contact area between the biasing spring and the driven-side clutch element by rotation of the biasing spring. According to the invention, lubricant applied to the engagement areas flies outward by rotation of the driving-side clutch element and deposited on the inner wall surface of the enclosure. Then, the deposited lubricant is actively supplied to the sliding contact areas between the biasing spring and the driving-side clutch element or the driven-side clutch element by utilizing rotation of the biasing spring. Thus, the effect of lubrication of the sliding contact areas can be enhanced.
