摘要： In a vehicle equipped with a power steering device for assisting the steering of the steered wheels by the steering wheel, when the steering angle of the steered wheels reaches the maximum steering angle, a steering control device restricts a target steering angle for operating the power steering device so that the steering angle or a reaction force acting against the power steering device does not exceed a value determined therefor, so to maintain the steering condition of the steered wheels stably without applying an excessive load on the power steering device. The target steering angle may be calculated as a value based upon rotational angle of the steering wheel and turning behavior control of the vehicle.

摘要： Two objective lenses are attached to a common holder. The holder is driven by an objective lens actuator, which integrally drives the two objective lenses. At this point, the objective lens (first objective lens) having a smaller diameter is arranged on a disk inner circumference side. In labeling, a reference pattern located at an inner circumference position is irradiated with a laser beam through the inner circumference-side first objective lens to obtain a gain which is used to finely move an objective lens actuator in a disk radial direction. The disk is irradiated with the laser beam through the second objective lens to generate an image in a disk surface while the objective lens actuator is driven with the gain.

摘要： The present invention aims at making it possible to successfully achieve fast recovery during magnetic resonance imaging in which the fast spin echo technique combined with the inversion recovery technique is implemented. A 180° x pulse is applied in order to excite spins. Thereafter, when an inversion time TI has elapsed, a 90° x pulse is applied in order to excite the spins. Thereafter, when a half of a time esp has elapsed, a 180° y pulse is applied in order to excite the spins. Thereafter, when the time esp has elapsed, the 180° y pulse is applied an odd number of times in order to sequentially excite the spins. Thereafter, when a half of the time esp has elapsed, the 90° x pulse is applied in order to excite the spins.

摘要： The present invention is directed to a brake control system for an electrically operated vehicle which is adapted to reduce a regenerative braking torque and add a hydraulic braking force to compensate for lack of the regenerative braking torque, when voltage of a battery exceeds an upper limit. A motor control unit is provided for controlling an electric motor to apply a rotating force to a wheel and apply the regenerative braking torque to the wheel. A pressure control device is provided for supplying pressurized brake fluid to a wheel brake cylinder in response to operation of a manually operated braking member to apply the hydraulic braking force to the wheel. A reducing device is provided for reducing the regenerative braking torque when the voltage of the battery exceeds a predetermined upper limit. And, a compensation device is provided for actuating the pressure control device to supply the pressurized brake fluid to the wheel brake cylinder when the regenerative braking torque reduced by the reducing device exceeds a predetermined level, e.g., when a rate for reducing the regenerative braking torque exceeds a predetermined rate, or when a reduced amount of the regenerative braking torque exceeds a predetermined amount.

摘要： The invention is directed to an arrangement for controlling a braking force applied to a rear wheel in a certain relationship with a braking force applied to a front wheel, so as to provide an ideal braking force distribution. Pressure control valves are disposed in a hydraulic circuit which communicates a master cylinder with at least a rear wheel cylinder. There are provided an auxiliary power source for discharging a power pressure and a hydraulic booster for regulating the power pressure and actuating the master cylinder. A changeover valve is disposed between the master cylinder and the control valves, and selectively placed in one of a first operating position for communicating the control valves with the master cylinder and blocking the communication between the control valves and the hydraulic booster, and a second operating position for communicating the control valves with the hydraulic booster and blocking the communication between the control valves and the master cylinder. When the changeover valve is placed from the first operating position to the second operating position, the control valves control the hydraulic pressure in the rear wheel cylinder in a certain relationship with the hydraulic pressure in the front wheel cylinder.

摘要： An anti-skid control system for use in an automotive vehicle is comprises of a real slip rate detecting device for detecting a real slip rate of the vehicle, a target slip rate setting device for setting a target slip rate of the vehicle, a braking force control device for adjusting a braking force in such a manner that a deviation between the real slip rate and the target slip rate becomes zero, a load measuring device for measuring a load applied to the vehicle, an correcting device for adding a value to the control device which is the product of a coefficient and the deviation between the real slip rate and the target slip rate and a coefficient adjusting device for decreasing the coefficient as the load decreases. If the load decreases during the vehicle's travel, the coefficient to be multiplied to the deviation between the real slip rate and the target slip rate decreases. Thus the quantity to be subtracted from the braking force is decreased and the current braking force is hardly reduced.
