摘要： In halt period during standby time, a cell plate node potential switching circuit changes the potential of a cell plate node to a low potential that is lower than a high potential adopted in a burst refresh operation. As a result, a potential difference between both ends of a PN junction of a memory cell transistor is decreased, thereby suppressing a leakage current flowing through the PN junction. Simultaneously, a word driver circuit changes the potential of a word line to a negative potential that is lower than a normal potential adopted in the burst refresh operation. As a result, an off state of the memory cell transistor is enhanced owing to decrease of a gate-source voltage thereof, thereby suppressing a leakage current flowing from the bit line to a charge storage node. Accordingly, a leakage current flowing through the PN junction of the memory cell transistor and a leakage current flowing from the bit line through the memory cell transistor to the charge storage node are both suppressed during the standby time. Thus, a refresh interval is elongated so as to decrease power consumption.

摘要： A traction control apparatus for use with an automotive vehicle having an internal combustion engine through which an output drive is transmitted to drive road wheels. A demand for first traction control is produced based on a slippage produced on the drive road wheels during acceleration. The first traction control demand includes a normal demand for first traction control continuing for a time shorter than a limit time and an exceptional demand for first traction control continuing over the limit time. A limit value is set for the number of times the exceptional demand is permitted. In response to the first traction control demand, at least one of fuelcut control and ignition control is performed to reduce the engine output drive. The first traction control demand is ignored when the number of times the exceptional demand has occurred reaches the limit value.

摘要： A flight velocity detection system using a truncated pyramid-shape multi-e Pitot probe in which an extreme end portion has a truncated pyramid-shape, a cylindrical hole is provided at the apex thereof, a total pressure tube of a smaller diameter than that of the cylindrical hole is secured at a position by a predetermined length determined by a relationship with the diameter of the cylindrical hole from the extreme end of the cylindrical hole, and groups of pressure holes comprised of a plurality of pressure holes are arranged in each of the truncated pyramid surfaces of the truncated pyramid shape. Items of pressure information detected by the probe are input into a velocity vector processor to convert them into electric signals, and signals are processed using pressure coefficients of the holes of the probe with respect to the velocity vector stored in advance in the velocity vector processor to calculate flight velocity vector (V, .alpha., .beta.) with respect to the probe axis from the pressure information and air density.

摘要： A rear wheel steering control system is provided. This system includes a traction control system which is responsive to generation of a difference in rotational speeds between front and rear wheels to recover traction of driven wheels and a compensating system which corrects a rear wheel steering angle, determined in a preselected relation to vehicle speed and a steered angle of the front wheels, based on the difference in rotational speeds between the front and rear wheels to provide a proper rear wheel target steering angle. The system restricts operation of the compensating system during operation of a traction control system to prevent a hunting frequency thereof from affecting the operation of the compensating system.

摘要： A system for controlling a steering angle for the rear wheels of a vehicle is provided. This system includes generally a rotational speed sensor for detecting rotational speeds of front and rear wheels to provide a difference in rotational speeds between the front and the rear wheels, an angle sensor for sensing a steered angle of a steering wheel, a steering controller for determining a rear wheel target steering angle, and an actuator for steering the rear wheels by the rear wheel target steering angle. The steering controller calculates a component of a difference in rotational speeds between the front and rear wheels caused by a difference in turning tracks therebetween and compensates for this component by the difference derived by the rotational speed sensor to provide a correction value for the rotational speeds between the front and rear wheels caused by acceleration during turning as a correction for a rear wheel steering angle. The steering controller determines the rear wheel target steering angle based on the correction.

摘要： A centrifugal fan has a circular main plate driven and rotated by a motor rotary shaft, a plurality of blades fixed to an outer circumferential portion of the main plate and spaced apart at predetermined intervals in a circumferential direction of the main plate, and a side plate attached to ends of the blades opposite to the main plate. An air inlet port is formed at the center of the side plate. The side plate inclines outward in centrifugal directions from the air inlet port and has an arcuate cross section with a predetermined radius of curvature. A dead water region reducing space is formed between the blades and the side plate. The dead water region reducing space forms a smooth flow between the two surfaces of each blade, bringing about desirable blade performance.
