摘要:
Difference in height is provided between a first surface of a molten metal bath at the upstream side in a vessel and a second surface thereof by means of a linear induction motor. A glass ribbon supplied to the first surface is formed to have a predetermined thickness while it is moved from the first surface to the second surface.

Provided is an antimicrobial raw material having excellent antibacterial and corrosion-resistance properties, which can be directly formed as a film even on a plastic substrate with low heat-resistance or a substrate whereof the color or properties are likely to change due to heat, and this can be achieved at relatively low cost. The antimicrobial raw material is a laminated structure which comprises a substrate layer and a copper-tin alloy layer disposed on the substrate layer, and which has a thickness ranging from 5 nm to 200 nm. The substrate layer is made of resin, natural fiber, or paper, the resin having the deflection temperature under load being 115° C. or lower when measured in accordance with ASTM-D648-56 under a load of 1820 kPa. The copper-tin alloy layer contains over 60 at % but no more than 90 at % of copper and 10 at % or more but less than 40 at % of tin.

To provide a generator capable of generating plasma and ozone with high efficiency and easy to handle, with a simple structure. An electrode part 10 is formed of electrodes 11 and 12 without dielectric material interposed therebetween. An arc-extinguishing capacitor 13 as a charge storage part for storing charge is connected in series to the electrode part 10. An AC power source 15 generating plasma by causing self-arc-extinguishing discharge between the electrodes 11 and 12 by applying AC voltage to charge and discharge the arc-extinguishing capacitor 13, is connected to both ends of a circuit in which the electrode part 10 and the arc-extinguishing capacitor 13 are connected in series. The arc-extinguishing capacitor 13 and one electrode 12 of the electrode part 10 connected thereto are unitized, for making the electrode part multi-polarized. A unit is constituted of a floating electrode serving as both of the one electrode 12 of the electrode part 10 and one electrode of the arc-extinguishing capacitor 13, an insulating material provided around the floating electrode and a grounding electrode provided around the insulating material.

Provided an antimicrobial substance that includes a base material layer, and a copper-tin alloy layer 5-200 nm in thickness disposed on the base material layer, the copper-tin alloy layer containing copper in an amount of more than 60 atomic percent but not more than 90 atomic percent, and containing tin in an amount of not less than 10 atomic percent but less than 40 atomic percent. The copper-tin alloy layer includes a Cu41Sn11 crystalline phase, and a Cu3Sn crystalline phase. The Q value (Ω/(nm·Cu atomic percent)), which is derived by dividing the sheet resistance (Ω) of the copper-tin alloy layer by the thickness of the copper-tin alloy layer and the copper content (Cu atomic percent), is 1.5×10−4-6.0×10−4.
