Title: Nut runner of bolt and nut fastener
Inventor: KOBAYASHI TAKASHI
IPC: B23P19/06

Abstract: PURPOSE: To make shaft center of a nut agree with shaft center of a bolt by supporting a nut socket on a rotary shaft through a long hole in such a way that it can travel freely and supporting the nut in a hold groove in such a way that it can travel freely. CONSTITUTION: If rickety motion occurs in a bolt hole, it is estimated that shaft center of a nut 2 is deviated from shaft center of a bolt 3 and that the nut 2 is not fitted in the bolt 3 smoothly. But, even if the shaft center of the nut 2 is deviated from the shaft center of the bolt 3, it moves freely along a long hole 12 in a scope of 2Xa in the X-axis direction by driving a rotary shaft 6 and rotating a nut socket 10 if the nut 2 is almost meshed with a tip of a male screw of the bolt 3. Moreover, a side of the nut 2 moves freely along an engaging face 13 on a groove side of a hold groove 10a in a scope of 2Xa in the Y-axis direction so that the shaft center of the bolt 3 agrees with the shaft center of the nut 2.

Abstract: PURPOSE:To obtain a resonant signal having large amplitude by presenting the uniform parts of high frequency magnetic field and static magnetic field on the circumference concentric with a central axis. CONSTITUTION:Atoms having the prescribed energy level of an atomic beam generated from an atomic beam furnace and collimator 16 are selectively converged via a deflecting magnetic pole 17 to form a plurality of ring-shaped or parallel beams at the central axis. This beam passes through the high frequency magnetic field of a coaxial mode resonator 18, and partial atoms are transferred to other level.
