摘要： An objective lens, an optical head, an optical disk apparatus and an information processing apparatus which can suppress deterioration of a focal spot caused by a drop in the diffraction efficiency. Inner and outer circumference areas converge a laser beam, out of laser beams having a wavelength λ1 which are diffracted by the inner and outer circumference areas, on a first information recording medium; the inner circumference area and a mid-circumference area converge a laser beam, out of the laser beams having a wavelength λ2 which are diffracted by the inner circumference area and the mid-circumference area, on a second information recording medium; and the diffraction efficiency of the laser beam having the wavelength λ2 is greater than the diffraction efficiency of the laser beam having the wavelength λ1.

摘要： A method for manufacturing an electric double layer capacitor comprising polarizable electrodes formed from a carbon material having graphite-like microcrystalline carbon, wherein said carbon material is stored for a predetermined period of time while holding said carbon material in contact with an electrolytic solution, and thereafter, at a temperature higher than room temperature, said capacitor is charged at least once with an end-of-charge voltage higher than an expected operating voltage of said capacitor, while applying to said electrodes, at the start of said charging, a pressure that is necessary to keep said carbon material from expanding in a thickness direction thereof during said charging.
