摘要:
A portable electric battery operated hair curler having a handle detachable from a curling barrel provided with an electric heating element. The handle contains rechargeable batteries and a recharger, and has a first set of electrical connectors at its front end for mating with a set of electrical connectors at the back end of the curling barrel. The handle further includes a second pivotally mounted electrical connection means in the front end of the handle connected to the battery charger for connecting the charger to an external power source. The pivoted second connection is accessible for use only when the barrel is detached from the handle and is then movable from a stored position in the handle to a position projecting from one side of the handle for connection to the external power source.

An electric hair curler comprises a handle and a barrel connected thereto for winding thereabout the hair. The barrel is provided with an electric heater for curling the hair wound on the barrel. The heater includes a plurality of resistor elements in the form of strips extending along the length of the barrel in generally parallel relationship with one another and being electrically connected in series by a corresponding number of bridging segments. The heater thus constructed is mounted on the barrel with the resistor elements thereof being exposed on the outer surface of the barrel in circumferentially spaced relationship with one another around the barrel, so that each of the resistor elements is in direct heat transfer contact with the hair to be wound on the barrel, thus greatly reducing the heat loss to assure effective heat transfer from the heater to the hair. This enables the heater to be energized by a battery or like source of relatively low current capacity to give off enough heat for curling treatment. Accordingly, the hair curler of the present invention may utilize a battery or the like as a power source for the heater, yet assuring an effective curling treatment of the hair.

A combined welding method with a filler wire using both a YAG laser and an electric arc, and a combined welding device with a filler wire using both a YAG laser and an electric arc. The welding is performed by directing a laser focus of a YAG laser on base materials and for welding in the vicinity of the focus by a filler wire, connecting a power source for applying a voltage to the filler wire between the filler wire and the base materials for welding, irradiating a YAG laser on the base materials for welding in the connecting condition, whereby an arc is induced to the filler wire by a plume (plasma-activated gas and the metal vapor), and holding the plume generated by YAG laser inside and outside of a keyhole.

A laser light L is emitted from a laser light source 6 to workpieces 1, 2, to form a laser molten weld pool 3, and immediately thereafter, an arc molten weld pool 4 is formed using an arc welding machine 7; thereby plates 1, 2 are welded. The arc welding machine 7 is provided with a filler wire to form a bead 5 on the plate 1. With the welding process according to the present invention, workpieces can be efficiently and securely welded regardless of shape and material of the workpieces.

摘要:
A combined YAG laser/arc welding apparatus performs a welding operation with a large depth of fusion and a deep fusion at a high efficiency. The welding apparatus includes an arc electrode which targets a point on a member being welded where a laser beam from a YAG laser is focused. While an arc power supply is connected between the arc electrode and the member being welded, the member being welded is irradiated by the YAG laser to produce plasmoid gasses and metal vapors or a plume which is effective to start an arc from the arc electrode. A combined YAG laser/arc welding operation takes place while keeping the plume within and without a keyhole. Welded surface is covered by a hood, and a shielded gas passed through a commutation metal network surrounds the welded focus to prevent an oxidation and keeps the plume maintained. A filler wire is fed to a molten pool.

This invention provides a new through weld method to carry out welding of a base metal made of aluminum or that of aluminum alloy using high energy beams wherein a shield gas ambience (an inert gas ambience) to cover a welding site in a submerged-scar is formed, even a shield gas ambience (an inert gas ambience) to cover a welding site irradiated by the high energy beams. Since the former shield gas ambience to cover the submerged-scar pushes the keyhole against the gravity and/or the gas pressure force of the latter shield gas supplied to the laser irradiation side, then the forming of hang down of beads and the resultant projection of the welding base metal are prevented.
