Inventor: TAKANO SHUNICHI
IPC: E05C17/34
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To attain fan-shaped opening and closing corresponding to a movement section by arcuate grooves by a method wherein a sub-plate is pinched between one end sections of a pair of arm plates and each frictional plate among adjacent plates and supported pivotally in a plate press-contact shape by connecting pins, the arcuate grooves are formed at each one of the mutually adjacent plates, and interlocking pins are installed to the others. SOLUTION: A sash A under a closed state is opened gradually to the outside, and an arm plate 1 and sub-plates 3, 4 for the sash open-close regulator are opened successively. Force exceeding static friction based on the friction of frictional plates at every opening and rocking and each press-contact friction of interlocking pins and arcuate grooves 16 and 13, 17 and 14 and 18 and 15 is applied to the sash A at that time. Each plate starts its rocking, and the sash A can be opened by small force resisting kinetic friction smaller than static friction after starting. When arm plates 1, 2 are opened maximally, the sash A is stopped at that time, and the sash A is stopped at an open place by the friction of the frictional plates and the press- contact friction of the interlocking pins and the arcuate grooves 16 and 13, 17 and 14 and 18 and 15.  Accordingly, possibility, in which a finger is caught to an included angle section at the time of the closing of both arm plates 1, 2, can be prevented.

IPC: B23K20/00
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To provide a friction welding method capable of precise positioning by using a servo motor. SOLUTION: With the main shaft 12 rotated by a servo motor 14, a specific relative rotary motion is imparted to a workpiece W1 to be fixed on the chuck 13 of the main shaft 12 and to a workpiece W2 to be fixed on a clamp 18.

Then, the rotation of the main shaft 12 is reduced so that a phase between the workpieces W1, W2 becomes a target phase at the time of stoppage. Just before the stoppage of the main shaft rotation, a main shaft torque is imparted to the accelerating side against a braking force by the frictional resistance of the joint surface, and further, when the phase between the workpieces W1, W2 becomes a stop phase, the main shaft torque is regulated to stop the main shaft rotation.
