  • Patent number: 5964308
    Abstract: A turn assisting mechanism assists a turning motion of a vehicle, such as a lawn mowing vehicle, so that the vehicle may not damage the ground (lawn grass, crops, etc.) when the vehicle makes a U-turn. The turn assisting mechanism is disposed near a wheel of the vehicle nearest to the center of turning of the vehicle about which the vehicle makes a U-turn. The turn assisting mechanism stretches out the rod of a hydraulic cylinder actuator to set a ground contact unit on the ground and lifts up the wheel nearest to the center of turning of the vehicle. When the vehicle makes a U-turn, the hydraulic cylinder actuator sets the ground contact unit on the ground so that the axis of turning of the ground contact unit passes the center of turning of the vehicle, and lifts up the corresponding wheel from the ground. The vehicle makes a U-turn on the ground contact unit without damaging the ground.

  • Patent number: 5943870
    Abstract: A refrigerator having an apparatus for controlling cooling intensity with one fan is disclosed. The refrigerator has ducts for supplying a freezing compartment and a fresh food compartment with cool air from a cooler, and one fan for blowing the cool air into the ducts. The ducts are selectively closed by a plate which pivots by a motor. Since the fresh food compartment is frequently used more than the freezing compartment, the plate is controlled to keep the fresh food compartment in a normal open state so as to supply the fresh food compartment with much more cool air. Thus, the distribution of the cool air in the freezing compartment and the fresh food compartment is effectively carried out.
