Abstract: A position controller provided in a controlling module obtains a difference between a detected rotation angle of a stylus and a target rotation angle, and determines an energization amount to a voice coil motor so that the difference becomes zero. A variable limiter circuit limits a driving current, which is supplied from the position controller, to a limitation value so that a rotation force applied to the stylus from the voice coil motor is constant. A target rotation angle issuing portion switches over the target rotation angle based on a relative position of a contact portion of the stylus.

Abstract: An attitude arm mounted to a support arm is rotatable about a pivot. The attitude arm holds a stylus gauge, which generates a signal representing deflection of the stylus in a measurement direction as the stylus follows a surface of a workpiece rotated on a turntable. An attitude switching mechanism allows switching between a first stylus attitude generally aligned with the turntable spindle axis and a second stylus attitude generally aligned perpendicular to the turntable spindle axis. To enable alignment of the measurement direction with the spindle axis, first and second adjusters enable the stylus tip to be moved perpendicular to the spindle axis and the measurement direction when in the first and second stylus attitudes, respectively. An orientation mechanism is provided to rotate the measurement direction of the stylus. A stylus tilt mechanism is provided to tilt the stylus about a tilt axis parallel with the measurement direction.

Abstract: A micro-cavity measuring equipment based on double optical fiber coupling includes a sight and transmitter, a controller, and a length measuring device. The equipment detects small changes in the position of an object with respect to a probe from a moment when the sight and transmitter starts working to another moment when the sight and transmitter stops working. The controller has a program to automatically control the whole measuring process. The measuring equipment is characterized in that the sight and transmitter consists of a laser unit, a data collecting and processing unit, and a double optical fiber coupling unit with its ends of incident and effluent optical fibers fixed on a coupler. A micro-cavity measuring method based on double optical fiber coupling consists of the following steps: inserting the probe into the micro-cavity and moving it in the measuring direction; sending signals to the length measuring device by the sight and transmitter to cause the length measuring device to record the corresponding position of the probe when the probe is contact with the sides of the micro-cavity; and then calculating the dimensions of the micro-cavity.
