Title: Butt joining method of steel plates by laser beam
Inventor: KITAGAWA TSUTOMU
IPC: B23K26/21
Filed: 1983-12-02
Abstract: PURPOSE:To eliminate the need for adjusting the deviating angle of laser beams and to reduce the time for welding by providing the two laser beams rotatable around the mid-point of a central spacing and cutting preceding and succeeding steel plates then subjecting the steel plates to butt welding. CONSTITUTION:The ends of preceding and succeeding steel plates 3a, 3b are clamped by clamps 1, 2 and thereafter the steel plates are cut by the laser beams of heads 4a, 4b. The clamps 1, 2 are moved in opposite directions by the distance determined by adding respectively half the distance between the beams and the beam diameter to butt the plates 3a and 3b. When a head 10 provided with a rotatng mechanism is rotated 90 deg., the traveling lines of the two laser beams coincide with the butt line. After the plate width in the weld position is detected, the heads 13a, 13b are moved to the mid-point of the plate width and thereafter the plates are subjected to laser-beam welding. The need for adjusting the deviating angle of the beam is eliminated by the above-mentioned method and the time for welding is reduced by half.

Title: Loop quantity control device for paper sheet
Inventor: NIIHARA TAKAYUKI
IPC: B65H5/06
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To form a prescribed quantity of loop on this side of a carrying member to prevent the generation of an abnormal image by detecting the loop of a paper sheet, and transmitting a drive force to a fixing member on the basis of this detection information. SOLUTION: A paper sheet P is carried along guide plates 10, 11 while it is nipped by a photoreceptor drum 7 and a transfer roller 9. Since a fixing drive clutch is in OFF state at this time, no drive force is transmitted from a drive motor to a heat roller 12, and the heat roller 12 is stopped. Therefore, a loop is formed on the top end of the paper sheet P reaching the heat roller 12 and a fixing pressure roller 13 in the area shown by A. When the loop of the paper sheet P is detected by a loop detecting sensor 17, the fixing drive clutch is ON, and the heat roller 12 is driven at the same linear speed as the linear speed of the photoreceptor drum 7 by the drive motor. Therefore, a toner image is fixed to the paper sheet P by the heat roller 12 and the pressure roller 13.
