Nanoemulsion compositions with low toxicity that demonstrate broad spectrum inactivation of microorganisms or prevention of diseases are described. The lamp 50 includes a first bezel 52 angularly movably supported on the support portion 33, and a second bezel 53 which holds the lens 54, and is mounted on the first bezel 52. The captured state is added to the state history. Further, a method for evaluating interrelation between wettability of a binder to an electrolyte and quality of a battery comprising the binder is disclosed. A method of making the delay units comprises depositing onto a substrate a timing strip having a starting point and a discharge point and depositing onto the same or another substrate a calibration strip. The boring tool is made of an aluminum material and thus has a reduced weight to reduce load of the spin member so as to machine the hole of the case even when a separate guide pad is not applied to the boring tool.
