The present invention provides a thermoplastic resin composition that gives a solar cell sealing sheet having, even without being crosslinked, good mechanical strength, solar cell sealability, transparency, and weatherability. In one scheme, a mobile station registers with a network entity each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. According to the method, in a first method step, at least one fuel is combusted inside the starting burner. A first voltage is applied to the first conductive film, and A second voltage is applied to at least one of the second measuring points with the location on the Y-axis adjacent to or overlapping one of the y-components. An internally threaded socket is welded to the transverse bulkhead parallel with the bulkhead and protrudes through a hole in the central flange so that a tow eyelet can be screwed firmly into the socket when needed and thereafter be unscrewed. Bi-circular and tri-circular methods are described.
