Providing a package and a method for manufacturing the package capable of achieving improvement in the degree of vacuum in the cavity, and to provide a piezoelectric vibrator, an oscillator, an electronic device, and a radio-controlled timepiece. In one embodiment, a method for heating a microelectronic substrate include generating a plasma, applying the generated plasma to a surface of the microelectronic substrate, and raising a temperature of the microelectronic substrate with the generated plasma applied to the surface of the microelectronic substrate. A very high surface area inorganic filler dispersed in the blend during formation thereof serves to increase the porosity of the film and thereby enhance electrolyte retention. The proxy can coordinate transcoding to take place to change the stream. The flanges taper radially outwardly to an outer edge that is sharp enough to penetrate vertebral end plates. The core has a hardness which gradually increases from a core center to a core surface, with the golf ball having specific values for the hardness difference between the core center and the core surface; the hardness difference – in JIS-C hardness units being not more than \xb12; the \u2212; the \u2212; the ; and the \u2212.
