According to one embodiment, a welding apparatus includes an irradiation device and a nozzle device. The irradiation device irradiates a target with laser light while scanning the laser light. The nozzle device includes an ejection port and ejects inert gas to an irradiation position of the laser light on the target through the ejection port located at a forward side in a scanning direction of the laser light relative to the irradiation position.

Welding apparatus and nozzle device

A secondary battery according to an embodiment includes a container having a pouring hole through which an electrolyte is poured, and housing the electrolyte, poured through the pouring hole, together with an electrode body; and a sealing lid which is fixed to the container and is closing the pouring hole. The sealing lid has a welding mark existing in a ring shape with a depth through the sealing lid to a lid body of the container, and an inner circumferential side molten mark existing in a ring shape overlapping with the welding mark, on the inner circumferential side of the welding mark in the sealing lid, with a depth corresponding to the thickness of the sealing lid.

Secondary battery and method of manufacturing the same

A secondary battery according to an embodiment includes a container having a pouring hole through which an electrolyte is poured, and housing the electrolyte, poured through the pouring hole, together with an electrode body; and a sealing lid fixed to the container and closing the pouring hole. The container has a plurality of grooves extending in parallel along the outer edge of the pouring hole, in a predetermined region that surrounds the periphery of the pouring hole, and the sealing lid is provided on the plurality of grooves in such a manner as to close the pouring hole and is fixed to the container.

The brittle workpiece splitting systemincludes a substrate holding mechanismfor holding a substrate, and a processing unitfor splitting the substrateheld by the substrate holding mechanismby a splitting process. The substrate holding mechanismhas an edge damperadapted to clamp an edge part of the substratefrom the sides of the opposite surfaces of the edge part, and support membersfor supporting the substratethereon at a predetermined height. The support membersare disposed on the side opposite the side of the edge damperwith respect to the intended split lineparallel to the edge part of the substrate. The edge damperhas an edge holderon which the substrateis seated, and a pressure barfor pressing the substrateagainst the edge holderto hold the substratebetween the edge holderand the pressure bar. Resin membersandmade of an elastic material having comparatively high rigidity are attached to parts, to be brought into contact with the substrate, of the pressure barand the edge holder, respectively. The support membersare made of a low-friction material to permit the horizontal movement of the substrateduring the splitting process.

Brittle workpiece splitting system and brittle workpiece splitting method

A laser beam type working apparatus and method are disclosed which join together metal conductors formed as an alternate layer structure over a surface side of a light-transmitting substrate with an interposing electrical insulator provided therebetween. The joining together of these metal conductors in achieved by directing a laser beam from a rear-surface side of the substrate to an underlying metal conductor to melt it so that it flows out upwardly in a molten state so that the underlying metal conductor is connected to an overlying metal conductor.

Method and apparatus for joining together associated metal conductors of

An apparatus for repairing a liquid crystal display comprises a common electrode, pixel electrodes facing the common electrode, and a liquid crystal sealed between the common and pixel electrodes. If the liquid crystal contains foreign matter which short-circuits the common and pixel electrodes to each other, a pixel electrode is irradiated with a laser beam such that at least a ring line region completely surrounding a portion touching the foreign matter is burnt away, whereby a region inside of the ring line region and a region outside of the ring line region are electrically insulated from each other.
