Abstract: The carbon dioxide recovery system (1) comprises an electrolytic reduction device (2) that generates a producer gas by reducing carbon dioxide, and a carbon dioxide separation device (3) that separates the carbon dioxide from the processed gas. The carbon dioxide separation device is provided with a first gas diffusion electrode (51), a second gas diffusion electrode (52), a liquid chamber (53) formed between the first gas diffusion electrode and the second gas diffusion electrode (52), and is configured to be supplied with an electrolytic liquid containing a compound that adsorbs and desorbs protons in an oxidation-reduction reaction, a first chamber (54) separated from the liquid chamber by the first gas diffusion electrode and configured to be supplied with the producer gas, and a second chamber (55) separated from the liquid chamber by the second gas diffusion electrode and through which the carbon dioxide separated from the producer gas flow.

Abstract: In the interline type charge transfer imaging device, two of the three groups of wiring through which driving pulses are sent to each of three groups of electrodes constituting vertical charge transfer devices are arranged in horizontal direction and the remaining one group of wiring is arranged in vertical direction. Light-shielding layer is installed on the vertically running wires and the electrodes connected with those wires.
