Title: One-side welding method for plates
Inventor: SUGITANI YUJI
IPC: B23K37/06
Filed: 1990-11-30
Abstract: PURPOSE:To increase the speed of root running with stable quality in butt welding of the plates by carrying out arc sensor automatic groove profile control by the high-speed rotational arc welding process and using ceramics backing material on the groove rear. CONSTITUTION:A narrow gap or a single-V groove 14 with the V-shaped bottom is formed on the butt ends of the plates 10 and the ceramics backing material 16 is arranged on the plate interior side. While an automatic welding machine 1 being traveled on a guide rail 12 fitted to the plate exterior, groove profile control by an arc sensor is carried out by the gas shielded arc welding process by a high-speed rotational arc with the arc rotational speed of >=10Hz and the arc rotational diameter of 1.0-4.0mm. At that time, under conditions of a wire diameter of 0.8-1.6mm, a welding current of >=300A and the welding speed of >=150cm/min, root running is performed by one-side welding at all positions from the exteriors of the plates 10. Consequently, a satisfactory back bead shape of high quality is obtained.

Title: Sucking hand
Inventor: NISHIMOTO KATSUSHI
IPC: B65H3/08
Filed: 1989-12-20
Abstract: PURPOSE:To make work at higher speed with a disc and spacer being gripped and laminated simultaneously, by providing a suction face sucking a commodity and that having a step difference with this face, in the suction hand of a robot system laminating magnetic discs. CONSTITUTION:The depth (step difference) of the hole that a hand 3 holds a spacer 5 is alingned to the thickness of the spacer 5. A hole is made so as to coincide with the hole 32 for vacuum suction by gluing an elastic body capable of machining, a silicon rubber 36, for instance, on the hole periphery of the contact face with a disc 4 because of there being a processing error on the spacer 5. The length from the bottom face of the silicon rubber 36 to the contact face with the spacer contact face 3b of a hand 3 is made slightly longer than the allowable processing error of the spacer 5. Since the arm of a robot is pressed according to the output of a force sensor 2, the spacer contact face 3b of the hand 3 is closely fitted to the spacer 5 and the bottom face of the silicon rubber 36 is glued to the disc 4.

Abstract: PURPOSE: To improve the durability of a fixing device by providing a friction reducing method with a step for inserting each copy sheet into a nip so that at least one end of the copy sheet is skewed to the motional direction of fixing rollers. CONSTITUTION: Main elements in a fixing part 120 are a heating and pressurizing roller 10 and a pressurizing roller 12 and a boundary between these fixing rollers 10, 12 is indicated as a nip 14. In fixing operation, a sheet S carrying an image 1 is passed through the nip 14. The sheet S is led into the nip 14 so that the sheet S is skewed from the moving direction (an arrow 18) of the sheet S passing the nip 14. The moving direction of the sheet S passing the nip 14 is vertical to the boundary between the rollers 10, 12. The skew is defined as an angular deviation from the moving direction of the sheet S passing the nip 14 and skewing expresses the skew. The skewed arrangement of the sheet S substantially surrounded by straight lines reduces friction on the surfaces of the rollers 10, 12.
