  • Patent number: 5756251
    Abstract: Disclosed is a method for making a lithographic printing plate from a photographic element according to the silver complex diffusion transfer process employing a coating development process with a small amount of developer, wherein the coating amount of the developer is 60 ml or less per 1 m.sup.2 of the photographic element and the developer contains a mercaptooxadiazole having an alkyl group of 4 or more carbon atoms or aryl group and an alkanolamine and/or a meso-ionic compound. The resulting lithographic printing plate has a high printing endurance and free from stains on the background in spite of carrying out the development by a coating method with a small amount of the developer for a short period of time.

  • Patent number: 5685386
    Abstract: In a vehicle having a pair of right and left front wheels and a pair of right and left rear wheels, when the front wheels are driven wheels, a differential limiting mechanism such as a multi-disc viscous clutch is arranged between axle members coupled to axles of the front wheels via universal joints, or when the rear wheels are driven wheels, the differential limiting mechanism is arranged between axles of the rear wheels. The differential limiting force of the differential limiting mechanism is controlled on the basis of various physical quantities (a steering angle .theta.h, a vehicle speed V, a brake hydraulic pressure P, a vertical acceleration G, and a road-surface .mu.) associated with the traveling state of the vehicle detected by sensors. Therefore, there can be provided a driven wheel differential limiting apparatus for a vehicle, which has high reliability and durability since the differential limiting force is controlled via, e.g.

  • Patent number: 5439244
    Abstract: An intersection of an extension of a front lower arm with an extension of a rear lower arm outside a transversely outer side constitutes a lower set point of a virtual kingpin axis. The transversely inner end portion of one lower arm of the front lower arm and the rear lower arm is connected to the body of the vehicle so as to be capable of being displaced in the longitudinal direction of the body. When the wheel is steered, the transversely outer end portion of the lower arm for the externally cornering wheel is displaced rearward while it pivots rearward about the transversely inner end portion of the lower arm, and the rearward displacement is transmitted so as to displace the transversely inner end portion of the one lower arm through a control link. The control link may be divided into two elements.

  • Patent number: 5158320
    Abstract: A suspension system for vehicles, in which the supporting center on the vehicle body side of an assist link is offset from the axial center of a bush of a suspension arm member so as to control the swinging locus of the suspension arm member at bumping of the wheel by the different swinging locus of the assist link. By the supporting center on the wheel support member side of the suspension arm member which is offset from the central axis of rotation of the wheel, the wheel at bumping is made toe-in for oversteering tendency to enhance turning ability at turning or is made toe-out for understeering tendency to enhance driving stability at turning and the camber angle of the wheel is made larger for enhancing straight driving stability or is made smaller for enhancing riding comfort and reducing steering power required for turning. Thus, the present invention makes it possible to change properly the toe-control and the camber-control according to characteristics of each kind of vehicle.

  • Patent number: 5094474
    Abstract: A suspension system for a vehicle in which lateral rigidity of a suspension arm member to resist external force in a transverse direction of the vehicle at turning, for example, is increased effectively by an assist link, and rigidity in the longitudinal direction of the suspension arm member to resist external force from the longitudinal direction of the vehicle while running over a rough road, for example, is decreased when the vehicle body side support of the suspension arm member close to the assist link swings in a longitudinal direction, with the vehicle body side support part of a vertical link member acting as a fulcrum. Thus, compliance to the input from the longitudinal direction of the vehicle is ensured fully and comfortableness to ride when running over a rough road, for example, and driving stability at turning, for example, can coexist at a high level.

  • Patent number: 5080185
    Abstract: A rear suspension system for a four-wheel-steered vehicle has a wheel support which supports a rear wheel for rotation and is connected to a rear wheel turning rod of the rear wheel turning mechanism. A pair of suspension arms are connected to the wheel support and guide the wheel support so that the rear wheel on the wheel support is turned about a kingpin axis in response to displacement of the rear wheel turning rod member. One of the suspension arms includes a so-called I-shaped arm which is connected for rotation to the wheel support at one end and to the vehicle body at the other end, and the kingpin axis intersects the tread of the rear wheel at a point which is offset in the longitudinal direction of the vehicle body from the point at which a side force acts on the rear wheel during cornering. A damping system is connected between the I-shaped arm and the vehicle body.
