摘要:
A polyvinyl acetal resin varnish which is so low in stimulus property, toxicity, environment-polluting property, offensive odor, and inflammability that no problem is caused in practical use, and which is high in safety, low in viscosity, and thus favorable in workability, and an application of the polyvinyl acetal resin varnish are provided. As an organic solvent for dissolving the polyvinyl acetal resin, there is used a nonaqueous solvent, preferably carbonate ester, and more preferably a mixed solvent composed of cyclic carbonate ester and chain carbonate ester, into which the polyvinyl acetal resin is evenly dissolved regardless of its type, resulting in varnish which is high in safety and low in viscosity. Since the varnish has an action of gelling the organic solvent, the varnish can be used as a gelling agent in various applications.

Disclosed is a nonaqueous electrolyte solution containing a sultone compound represented by the Formula 1 below (wherein R1 to R4 respectively represent a hydrogen, a fluorine, a hydrocarbon group with 1 to 12 carbon atoms that may contain fluorine atom(s), n represents an integer of 0 to 3, and when n is 2 or 3, the two or three R3 groups are independent from each other and the two or three R4 groups are independent from each other), and an ethylene carbonate having a hydrogen atom substituted by a fluorine atom. Also disclosed is a lithium secondary battery employing the nonaqueous electrolyte solution. This nonaqueous electrolyte solution does not cause an increase in the internal resistance of a nonaqueous electrochemical device and improves the lifespan characteristics of the device. The lithium secondary battery containing the nonaqueous electrolyte solution exhibits greatly improved cycle charge/discharge characteristics at high temperature, and has excellent charge/discharge load characteristics.

摘要:
A route display apparatus and method are provided. The apparatus includes a search unit that searches for a plurality of routes in which a plurality of destinations are stopped by in a different stopping order combination in each route. The apparatus also includes a prediction unit that predicts, for each of the routes, a travelable position that can be reached with a remaining amount of a battery. The prediction unit is configured to predict, for each of the routes, a necessity of charging based on whether the travelable position is on a side of a departure point in relation to a final destination. The apparatus also includes a display control unit that displays, for each of the routes, the necessity of charging in association with a corresponding stopping order for each of the routes, on a display part.
