    摘要： An electrorheological fluid damper for a slide mechanism including a base and a table, is made up of base-side conductive arcuate pipes different in diameter (serving as a positive electrode), and table-side conductive arcuate pipes different in diameter (serving as a negative electrode) which are arranged alternately in such a manner that they are coaxial with one another, so that the contact areas of the electrodes which are in contact with the electrorheological fluid are increased without increase of the size of the damper itself. When the table is being slid, no voltage is applied to the electrorheological fluid, so that the viscosity of the electrorheological fluid is minimum, being of only its solution, and when the table is stopped, voltage is applied to the electrorheological fluid, so that the viscosity of the electrorheological fluid is increased. Thus, the electrorheological fluid damper requires no high voltage and is not bulky, and is high both in positioning accuracy and in shock absorbing performance.

Initial contact angles βOUT, βIN of the two rows are smaller than predetermined contact angles αOUT, αIN. The extent [αIN−βIN] to which the initial contact angle βIN of the balls 6b, 6b in the inside row is made smaller than the predetermined contact angle αIN of the balls 6b, 6b is made larger than the extent [αOUT−βOUT] to which the initial contact angle βOUT of the balls 6a, 6a in the outside row is made smaller than the predetermined contact angle αOUT of the balls 6a, 6a {[αIN−βIN]>[αOUT−βOUT]}. By this configuration, imparting the predetermined contact angles αOUT, αIN to the balls 6a, 6b in the two rows in the completed state, and the preloads and contact angles of the balls 6a, 6b in the two rows are made proper.

    摘要： In measuring the accuracy of a thread groove of a ball thread formed in a nut by using an electric micrometer, a displacement of one point on each of a pair of flanks of the thread groove is measured along a longitudinal direction of the thread groove, and a pair of measured data sequences are obtained respectively for the pair of flanks. The data elements of the pair of measured data sequences are grouped into a plurality of groups so that each group includes a pair of data elements which are respectively contained in the pair of measured data sequences and which are corresponding to each other. The accuracy in the depth direction of the thread groove with respect to a reference thread groove is obtained on the basis of a sum of the data elements in each group, and the accuracy in the thread axis direction is obtained on the basis of a difference between the data elements in each pair.
