A green phosphor having a magnetoplumbite-type crystal structure, which contains at least Mn, La and Tb, which contains at least Tb and La but does not contain Ce or which contains at least Mn, La and Zn. The green rubber tread stock is held from above for moving by inserting a plurality of transfer pins downward into both edges of the green rubber tread stock such that each transfer pin is angled toward a closest laterally outside edge. A portion of the first conductive line in contact with the first diffusion region is doped to an opposite conductivity type as the first diffusion region. The output switch is configured to isolate the low power path from the high power path in the high power mode. In addition, the present invention can reduce the power consumption while simplifying the circuit construction by allowing a programread operation to be simultaneously implemented on a single sense amplifier circuit. The missed call information includes the voice of the originator requesting the PTT call, and the voice of the originator is output when confirmation of the missed call information is requested.
