Abstract: An underwater welding apparatus includes: an underwater welding head provided underwater and having, at its leading end, a nozzle section from which laser light is emitted; a shied cover formed of an elastic member and provided around the nozzle section so as to form, at the leading end of the underwater welding head, a space where water is excluded by shield gas; and an expansion/contraction member having a discharge hole for discharging water and shield gas containing metal dust particles from an inside of the shield cover, the discharge hole being increased in diameter as pressure inside the shield cover rises, while being reduced in diameter as the pressure inside the shield cover falls.

Abstract: The solar cell module includes a plurality of solar cells that are sealed inside the sealing layer made of resin with light transmission properties, an identification label sheet that is sealed inside the sealing layer in a region different from the solar cells in a planar direction of the light transmissive substrate, and that is made of resin on which identification management information is noted, and a protective sheet that is stacked on the identification label sheet on the side of the light transmissive substrate, sealed inside the sealing layer, made of resin with light transmission properties, and contains therein ultraviolet absorbent. The protective sheet has greater ultraviolet absorbing properties in a specific thickness than a light-receiving-side sealing layer of the sealing layer, which is positioned on the side of the light transmissive substrate relative to a light-receiving surface of the solar cells in a thickness direction of the sealing layer.

Abstract: A solar battery module includes a first cell line formed by arraying a plurality of solar battery cells in a first direction, a first inter-cell lead that connects the solar battery cells in the first cell line in an array direction, a second cell line formed by arraying the solar battery cells in parallel to the first cell line, a second inter-cell lead that connects the solar battery cells forming the second cell line in an array direction, and an inter-line lead that extends in a direction perpendicular to the first direction and electrically connects the first inter-cell lead and the second inter-cell lead, in which at least a portion of the inter-line lead overlaps the solar battery cell.

Abstract: A solution of a chromium compound is impregnated into a silica-alumina carrier made of alumina and containing 1 to 5 weight % of silica relative to the weight of the carrier, thereby to obtain a decomposing catalyst carrying 10 to 15 weight % of chromium oxide relative to the weight of the catalyst in terms of Cr2O3. By contacting mixed gas obtained through partial oxidation of heavy oil and/or coal with the decomposing catalyst, COS and HCN contained in the mixed gas are decomposed/removed. In this case, transition of alumina into boehmite can be suppressed owing to coexistence of silica and chromium oxide, so that COS and HCN can be decomposed by highly active catalytic reactions over a long time.

Abstract: A magnetic disk drive has a housing for a 3.5 inch form factor and disk media of a diameter for a 2.5 inch form factor. The smaller disk media rotate at a high speed while consuming low electric lower and generating less heat while providing for quick access speeds. Usually, when the magnetic disk media are rotated at a higher speed, the electric power consumption and heat generation are increased because of the load increase. This problem is avoided with the use of cooling fins placed about the periphery of the disk media. Further, the smaller size disk media enable a decrease in torque loss during on-load rotation with the media, and a decrease of electric current to the spindle motor during rotation.

Abstract: A magnetic disk apparatus wherein a magnetic member mounted on a bobbin made of a non-magnetic material is disposed at a specific position effective for the full range of movement of a transducer head such that the magnetic member and thus the head is attracted by the leakage flux in a VCM, and the attracting force thus derived has a component that produces a rotation moment in only one direction around the pivot axis of the head to bias the head toward a non-data portion of a data storage disk.

Abstract: A disk drive for driving storage disks can suppress warping of the disks even when thinner disks and a less rigid hub are employed for the purpose of reducing the size of the disk drive. The disk drive includes a plurality of disk-type storage media, spacers placed between respective two adjacent disk-type storage media, a hub on which a stack of the disk-type storage media and the spacers is fitted, the hub having a surface contacted by the disk-type storage medium positioned on one end of the stack, and a clamp which presses the stack onto the surface of the hub.

Abstract: A magnetic disk apparatus has a base member and a cover mounted on the base member to form an enclosure having at least six magnetic disks rotatably supported therein. First and second transducers are included for writing information on and reading information from upper and lower surfaces of adjacent ones of the magnetic disks. The transducers are supported by leaf springs in close proximity to both surfaces of adjacent ones of the magnetic disks. The leaf springs extend in a radial direction with respect to the magnetic disks and are supported on one end by a plurality of head arms. The leaf springs are arranged substantially within the same plane parallel to the magnetic disks so they do not overlie one another. A voice coil motor is provided for moving the head arms in order to position the transducer pairs in predetermined positions. A circuit board is included for controlling the magnetic disk apparatus.
