  • Patent number: 4976328
    Abstract: A rear wheel turning mechanism of a four wheel steering system includes a rear wheel turning rod which is connected to the rear wheels of the vehicle and is adapted to be displaced so as to turn the rear wheels. An electric motor is operatively connected to the rear wheel turning rod and the steering wheel so as to displace the rear wheel turning rod, which turns the rear wheels in response to the operation of the steering wheel. A rear-wheel-neutralizing spring urges the rear wheel turning rod to the neutral position in which the rear wheels are held in the straight-ahead position. A clutch is interposed between the electric motor and the rear wheel turning rod and is adapted to disconnect the latter from the former to permit the latter to return to the neutral position under the force of the rear-wheel-neutralizing means.

  • Patent number: 4958217
    Abstract: An image processing apparatus capable of extracting a particular image area from an image by designating a color hue of the desired particular image area. After indication on one or more points in an object region of interest, an initial range of hue or of brightness is designated, and a predetermined color is painted throughout a region adjacent to the indicated point(s) and having a hue or brightness, respectively, within the predetermined range. If that process results in the coloring of an area exceeding that which the operator desires to cover, the predetermined range of hue or brightness, as the case may be, is narrowed, and the process is repeated.

  • Patent number: 4953648
    Abstract: A rear wheel steering mechanism for steering rear wheels of the vehicle is urged by a spring so as to allow the rear wheels to take a neutral position or a position at which the rear wheels run in a straight direction. Control over the driving of the motor connected to the rear wheel steering mechanism allows the rear wheels to be steered at a given steered angle against the urging force of the spring. The rear wheels are always returned to the neutral position by the spring by disconnecting a clutch interposed between the rear wheel steering mechanism and the motor whenever abnormality is found. Presence or absence of abnormality in a drive control system of the motor is checked or an alignment of a reference position of the motor is made, in such a state that the clutch is disconnected, immediately after an ignition switch was turned on yet prior to control of the rear wheel steering.
