Abstract: PURPOSE:To obtain a vehicle-to-vehicle distance detecting device which is reduced in calculation quantity and can stably detect the distance between vehicles. CONSTITUTION:An image processor 11 processes the front road image from a video camera 10 and detects the distance to a vehicle, and a warning level judgement means 12 judges the warning level from the detected value and the detected value of a vehicle speed sensor 13 to actuates a warning device 14. At this time, the image processor 11 detects the horizontal edge showing the position of the precedent vehicle in the road image, calculates the vehicle distance from the position to its own vehicle, and detects two vertical edges showing the width of the precedent vehicle and its width, and detects a horizontal edge and two vertical edges in a newly inputted front road image with the horizontal edge and vertical edges, thereby detecting the distance to the precedent vehicle while tracking and detecting the precedent vehicle according to the vertical edge width and the calculated width of the vehicle. Consequently, the calculation quantity is decreased and the stable detection for the distance to the vehicle is enabled.

Abstract: PURPOSE:To decrease the number of components required and to make an inverter device small-sized and inexpensive by suitably selecting either a braking circuit or a boosting chopper circuit to form each circuit between a voltage type inverter. CONSTITUTION:When an induction motor 6 is operated in a regenerative mode and the voltage EDC at a DC capacitor 4 is raised by regenerative power, a thyristor 18 is turned ON and a braking circuit 9 is formed by a resistance 7, the thyristor 18 and a transistor 16. When an converter 1 goes wrong, a thyristor 17 gets 'ON' stage, while the thyristor 18 'OFF' state. A boosting chopper circuit 10 is formed by the thyristor 17, transistor 16 and further a capacitor 12, a reactor 13 and a diode 15, which controls voltage EDC. Both braking circuit and boosting chopper circuit can thereby be suitably selectively used, so that the number of components can be decreased.

Filed: 1989-06-15
Abstract: PURPOSE:To make a ventilation efficiency high and noise low, by positioning the suction opening side curvature radius center of an impeller blade curved line shape at a more advanced position than the blade, and the discharge side curvature radius center at a more retreated position than the blade, against the rotation direction of the impeller. CONSTITUTION:When an impeller 24 starts a high speed rotation by means of a commutator motor 31, an air current flows into the impeller 24 through an air intake hole 22, and flows out through an exhaust opening 32 via an air guide 23 as it keeps on cooling the motor 31. In this instance, there occurs a phenomenon that the current speed V3 of the suction side 28a becomes faster due to the shape of a blade 28, on a blade 28 suction opening side 29, being arranged so as to bulge toward a blade 28 suction side 28a, and at the same time, the current speed V2 of the pressure side 28b becomes slower due to the pressure side 28b being of a dent shape, and currents are equalized in terms of the suction side 29 as a whole. Also, the collision with the air current at the blade 28 tip portion on the suction side 29 is also moderated, that is, the air current which has little disorder is discharged from the discharge side 30 of the blade 28.
