  • Patent number: 4610328
    Abstract: The rear wheels of a vehicle are turned in response to the turning of the front wheels upon operation of the steering wheel. A rack member is provided to be operatively connected with a movable member of the front wheel steering system which is moved right and left in response to operation of the steering wheel so that the rack member is moved together with the movable member. The rack member is in mesh with a pinion fixed to an end of an output shaft whose rotation is transmitted to the rear wheel steering system as steering force for moving it by way of a transmission shaft.

  • Patent number: 4606318
    Abstract: A Karman vortex generator is disposed in the air intake passage of an internal combustion engine. The frequency of the Karman vortex generated by the generator is detected by a Karman vortex frequency detector to measure the flow rate of intake air. The frequency of the Karman vortex is in proportion to the flow rate of intake air with a Strouhal number being the constant of proportionality thereof. However, when the flow rate or the flow velocity of intake air is within a certain range, the Strouhal number fluctuates and the proportionality between the Strouhal number and the flow rate of intake air is broken. This range is shifted when the kinematic viscosity of intake air changes. The kinematic viscosity of intake air depends upon the temperature thereof.
