    摘要: A method of measuring a distortion of a transmitting beam, characterized in that a transmitting beam is emitted from a beam generator and projected onto a screen as a bright spot, the bright spot is scanned over a surface of the screen, and a distortion of the transmitting beam is measured on the basis of a distance between a first location of the bright spot on the screen at a first time when the transmitting beam is incident on a beam receiving device in a specified incident direction upon transmitting through a measured body, and a second location of the bright spot on the screen at a second time when the transmitting beam is incident on the beam receiving device in the specified incident direction upon not transmitting through the measured body. A surface shape of a three-dimensional object may also be measured on the basis of a distance between a first location of the bright spot on the screen at a first time when the transmitting beam is incident on a beam receiving device in a specified incident direction upon being reflected from a surface of a three-dimensional measured body, and a second location of the bright spot on the screen at a second time when the transmitting beam is incident on the beam receiving device in the specified incident direction upon being reflected from a surface of a reference body. The present invention provides measurements having improved accuracy for objects of any size irrespective of the resolution of the beam receiving device.

    摘要: A power transfer device including a main clutch, a cam mechanism and an electromagnetic pilot clutch mechanism coaxially assembled within a cylindrical space between an external cylindrical rotary member and an internal rotary member, wherein an electromagnetic coil of the pilot clutch mechanism is applied with an electric current to produce pilot torque, the cam mechanism is applied with the pilot torque to produce thrust force in an axial direction, and the main clutch is engaged by the thrust force applied from the cam mechanism to effect drive connection between the rotary members. In the power transfer device, residual thrust force of the cam mechanism is electrically or mechanically decreased at an instance when differential rotation of the rotary members is reversed.
