The self-opener closure comprises a spout having a projecting lower rim which is to be molded or glued to a composite packaging, an associated rotary cap as well as a self-opener sleeve arranged within the spout. The first wafer exclusively supports the evaluation circuits required for measuring the applied pressure and a capacitive electrode, and the second wafer has a recess formed by surface micromechanics processes, in which the counter electrode to the capacitive electrode of the first wafer is situated. According to some embodiments, a polarizer for selecting a pump wavelength polarization delivered to the wavelength converter may include a beam combining structure. In addition, the protective film can also give the aluminum or aluminum alloy article a long-lasting attractive appearance by preventing a colored sealed oxide layer of the aluminum or aluminum alloy article from fading. The call is received by an application gateway center installed on the Internet.
