This invention provides azeotrope-like compositions of 1,1,1,3,3-pentafluoropropane and water that are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics. The battery pack includes a safety device for spraying a material to prevent or restrain the fire or the explosion of the battery pack when the temperature of the battery pack exceeds the critical temperature level threatening the safety of the battery pack. Each of the selection transistors has a lower gate layer and an upper gate layer that are formed by lamination with each other on the principal surface, and is contained in a memory cell together with one of the memory transistors. The equalizer includes a filter with a plurality of taps that are adapted through use of an adaptive algorithm that uses an estimated pilot estimated from the received wireless signal. The bulk feed adapter cap may further comprise at least one fluid-communication cap.
