Provided are a laser-bonded component and a production method for same that ensure sufficient bonding strength using little laser energy and which cause little increase in surrounding temperature. A nickel layer, being a surface layer, is formed having sufficient thickness on the upper surface of a copper plate that is uppermost amongst at least two superposed copper plates, a laser is irradiated from above the nickel layer, a re-solidification section formed by fusing and alloying the copper in the copper plates and the nickel in the nickel layer is formed through to inside the bottommost copper plate, and the copper plates are bonded together. The re-solidification section having high breaking strength is formed by the alloying of the nickel and the copper. As a result, the copper plates can be bonded with a small welding surface area and little laser energy.

An assembled battery includes unit batteries and a connecting member. Each of the unit batteries includes negative and positive electrode terminals. The connecting member has thin portions, and a thick portion that is a rest other than the thin portions. The thin portions are welded to the respective positive electrode terminals or the respective negative electrode terminals. When the connecting member is connected to the positive electrode terminals of the unit batteries, an area of each of the thin portions is equal to or more than an area of the connecting surface of each of the positive electrode terminals. When the connecting member is connected to the negative electrode terminals, an area of each of the thin portions is equal to or more than an area of the connecting surface of each of the negative electrode terminals.

The present invention relates to an electrical contact material having a surface layer made of a noble metal or an alloy having the noble metal as its main component, a method for manufacturing the same and an electrical contact using the same. Recently, electrical contact materials having excellent abrasion resistance are used for sliding electrical contacts such as a connector terminal of an automobile harness, a contact switch mounted in a cellular phone and terminals of a memory card. Although there have been known ones having an organic coating film composed of either aliphatic amine or mercaptan or a mixture of the both provided on the electrical contact material described above as the electrical contact materials having excellent abrasion resistance, they have had problems that even though they are effective with a low load of 0.5 N or below, abrasion accelerates when the load exceeds 0.5 N and sliding characteristics drop under a high-temperature environment. The invention solves the abovementioned problems by providing an organic coating film formed of an organic compound containing aliphatic amine on the electrical contact material.

A sealed type container accommodating a semiconductor substrate is positioned to a load port of a semiconductor manufacturing apparatus. The semiconductor substrate is taken out of the container. An ionizer is used for static-charge-eliminating the semiconductor substrates before and after process treatment in a transport area between the load port and a treatment section. The static-charge-eliminated semiconductor substrate is accommodated in the container positioned to the load port. Thus, it is possible to decrease foreign materials adhering to the semiconductor substrate and errors in handling the semiconductor substrate.

An objective is to provide a carrier exhibiting stable charge providing ability in which sufficient charge can be provided to toner having a small particle diameter, and no image contamination such as fog caused by toner scattering via lack of electrification is generated. Another objective is to provide a carrier capable of maintaining a charging level of no interference for image formation even under the image forming condition at which a charging level for printing a number of prints continuously is difficult to be maintained. Disclosed is a carrier comprising a core particle made of ferrite possessing Mg and coated thereon, a resin, wherein the core particle has a ratio of the number of irregular-shaped core particles of at most 5%, based on the total number of core particles, and a surface of the core particle has grains having a maximum grain diameter of 2-5 μm.
