  • Patent number: 5511874
    Abstract: A drive transmission mechanism for a biaxial extruder includes first and second output gears respectively fitted with an axial displacement on first and second output shafts which are connected to first and second screws of a biaxial extruder. A first lower gear and a first upper gear are arranged below and above the first output gear. A second lower gear and a second upper gear arranged below and above the second output gear. A reduction gear train is provided for quartering the drive force of a common drive source equally and distributing the quartered drive force to the first lower gear, the first upper gear, the second lower gear and the second upper gear.

  • Patent number: 4907877
    Abstract: A method and apparatus for determining or adjusting a projecting direction of a light beam emitted from an automobile headlight is provided. In a first aspect of the present invention, the peripheral region of a light beam is used in determining its projecting direction. In particular, a region definable in a light pattern of the projected beam having a proportionality relation between log S and I, where S indicates the value of an area having light intensity I or above, is determined and its outer contour or any predetermined point in the contour is used in determining the projecting direction. In a second aspect, apparatus for determining a projecting direction of a light beam emitted from an automobile headlight includes an indicator which automatically indicates a predetermined position of a light pattern of the light beam projected.

  • Patent number: 4567667
    Abstract: A method and apparatus for measuring the inclination of the wheels of an automobile is provided. In accordance with one form of the present invention, there is provided a toe angle detecting device including a pair of detector plates which are normally spaced apart from each other to allow the corresponding wheel of the automobile to be located therebetween and which are pressed against the wheel from both sides when activated to determine the inclination of the wheel with respect to the longitudinal center line of the vehicle, i.e., toe angle of the wheel. In another aspect, a particular link mechanism is provided to interconnect four support members on which the four wheels of the automobile are placed, and the link mechanism is structured to determine the direction of the longitudinal center line of the automobile with respect to the reference line of the link mechanism.
