There is provided a hairspring including a main body portion that extends around a central axis along an Archimedes curve; an outer end curve portion that extends along a circumferential direction around the central axis on an outer side in a radial direction from the main body portion; and a reformed portion including a first bent portion that connects the main body portion and the outer end curve portion to each other and is bent outward in the radial direction from a tangent line of the Archimedes curve in a first connection portion with the main body portion, and a second bent portion bent inward in the radial direction from the outer end curve portion in a second connection portion with the outer end curve portion, and in which at least one is curved of the first bent portion and the second bent portion.

A method and apparatus for electrostatic spray deposition (ESD) for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate constructed of nickel-YSZ cermet. By reducing the thickness of the electrolyte, and thereby reducing the cell internal IR drop, an intermediate temperature SOFC (ITSOFC) can operate at 600-800&#xb0; C. A collar positioned at a distance from a discharge end of a spray nozzle enhances a spray pattern of a precursor including the electrolyte material and thus provides a very thin electrolyte layer.

A ladle after teeming for a continuous casting and a subsequent slag discharge is mounted on a ladle truck and then moved by the ladle truck to a tapping station. The ladle on the ladle truck is then stationed over a predetermined stand-by time and is then immediately moved to a tapping position to receive a molten steel from a converter. The ladle is quickly heated during the stand-by time, by a regenerative-type burner system carried by a ladle lid which is attached to the ladle to cover the top opening of the ladle. This allows the tapping temperature of the molten steel to be set to a low level, offering advantages such as a remarkable reduction in the consumption of carbonaceous materials as the temperature controller, as well as extended life of ladle refractories through suppression of thermal attack. At the same time, consumption of fuel gas for heating the ladle by the burner system is reduced to contribute to saving of energy.
