Title: Axial tension control type bolt and nut
Inventor: HAMAGUCHI TAKUZOU
IPC: F16B37/00
Filed: 1994-05-13
Abstract: PURPOSE:To provide desired bolt axial tension by tightening a bolt through the center hole of a nut with a bearing integrated via many steel balls laid between a recessed box and the nut body rotatably coupled to the inside thereof loosely with a dedicated torque wrench. CONSTITUTION:A nut body 3b is rotatably coupled to the inside of a box 3a having a cross sectional area of recessed form as well as a through-hole at a bottom center for allowing the insertion of a bolt 1, and many steel balls 3c are arranged between the box 3a and the nut body 3b, thereby forming a thrust bearing. Then, after deciding the nominal diameter of a thread and desired axial tension, tightening torque corresponding to the decided values is obtained from a chart, and a dedicated torque wrench is set to the obtained values. When a nut body 3b is tightened with the torque wrench, proper axial tension control can be done with freedom from looseness due to a vibration, a shock or the like. According to this construction, no personal difference appears in tightening the nut body 3b and the occurrence of a trouble such as excessive tightening and insufficient tightening can be properly prevented.

Title: Controller for leg-type mobile robot
Inventor: TAKENAKA TORU
IPC: B25J5/00
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To easily and properly control an actual reactive force applied on a robot without any interference by providing a leg part rotational amount deciding means or the like. SOLUTION: The coordinate of a first target sole floor reactive force center point and the coordinate of a second target sole floor reactive force center point are rotated and moved around a normal vector by amounts equal to a rotational angle θ (both-leg compensating angle) with respective target full- floor reactive force center points set as rotational centers. In this case, by simultaneously operating both-leg compensating angle, each sole X compensating angle and each sole Y compensating angle, the changing amount of each actual sole floor reactive force is a sum of a changing amount when each is singly operated. Accordingly, these operations have linear characteristics.  Thus, each actual sole floor reactive force moment is calculated in the moving target sole floor reactive force center point and, based on each, a sole is rotated around the sole floor reactive force center point, and a moment around the point is controlled to a desired value. Thus, control is facilitated without any interference between actual full-floor reactive force and each sole floor reactive force.
