Title: Method of laser spot welding for aluminum material
Inventor: EGUCHI NORITAKA
IPC: B23K26/00
Filed: 2000-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a method of laser spot welding for an aluminum material, with which a crater processing is unnecessary and the productivity of a spot welding is remarkably improved. SOLUTION: An upper plate 1 and a lower plate 2 which are to be welded are laminated at their tip parts which are to be spot-welded, the tip parts are clamped and held by two plate-shaped lower pressing members 4 and three rod-shaped upper pressing members 3. The radiation of a laser beam is started at a position which is apart from the position where a spot welding by laser beam is to be carried out by a distance equal to or greater than the minimum plate thickness of the upper plate 1 and the lower plate 2, and the position irradiated by the laser beam is linearly moved from the position where the spot welding is to be carried out to a stopping position of irradiation by the laser beam which is apart from the position where a spot welding is to be carried out by the same distance equal to or greater than the minimum plate thickness of the upper plate 1 and the lower plate 2. The moving speed of the laser beam is made slower at the position which is to be spot-welded in order to give a sufficient amount of heat, and a through penetration part 6 is formed at this position by melting also the lower plate 2. Thus a crater is not formed at the joined zone.

Abstract: PROBLEM TO BE SOLVED: To obtain an environmentally safe carrier material for electrophotographic development by calcining a composition consisting of specified proportions of manganese oxide, iron (III) oxide and a titanium dioxide to form a spinel structure. SOLUTION: Titanium dioxide is added to a mixture of 10-50 mol% manganese oxide and 90-50 mol% iron (III) oxide by 0.5-10 wt.% of the mount of the mixture and the mixture is calcined by heating at 700-1,200 deg.C for 30 min to 2 hr to obtain a mixture of particles having a spinel structure containing manganese oxide and iron (III) oxide. A slurry prepared by wet-comminuting the mixture is spray-dried to form spherical dry beads. After classification, the beads are sintered in a kiln having <2% oxygen content. Since titanium dioxide is substituted for iron in crystals by the sintering, the mixture has enhanced property of iron (II) and the magnetic moment of the resulting material is reduced while retaining the electric conductivity. The material is suitable for use as a carrier for a color copying machine because the magnetic moment can be controlled to <6,320 Am2/g.
