Abstract: A carbon dioxide recovery system includes an electrochemical cell that includes a working electrode, a counter electrode, and an insulating layer. The electrochemical cell is configured to repeat an adsorption mode and a desorption mode. In the adsorption mode, a first voltage is applied between the working electrode and the counter electrode to supply electrons to the working electrode and cause the working electrode to adsorb carbon dioxide in a gas to be treated. In the desorption mode, a second voltage different from the first voltage is applied between the working electrode and the counter electrode to emit electrons from the working electrode and desorb the carbon dioxide from the working electrode. At least one of the adsorption mode and the desorption mode has a pause period during which application of a predetermined voltage between the working electrode and the counter electrode is temporarily suspended.

Abstract: A motor includes: a rotating shaft; a motor portion; a circuit board; a case having a circuit housing recess portion for housing the circuit board; and a cover made of a synthetic resin and sealing the opening portion of the circuit housing recess portion. The cover has an outer circumference rib and an inside rib. The outer circumference rib is located on the outer circumferential side from the opening end surface of the circuit housing recess portion and projects from the outer circumferential edge of the cover toward the front surface side of the cover and the rear surface side of the cover. The inside rib is located inside from the opening end surface and projects at least either on the front surface side of the cover or on the rear surface side of the cover.

Abstract: An acid gas recovery system includes an electrochemical cell and an electrolytic solution. The electrochemical cell includes a working electrode and a counter electrode and is configured to transfer electrons between the working electrode and the counter electrode in response to an application of a voltage between the working electrode and the counter electrode. The electrolytic solution is disposed between the working electrode and the counter electrode and contains at least a reducing agent configured to reduce reactive oxygen. At least one of the electrochemical cell and the electrolytic solution contains an adsorbing agent. The adsorbing agent is configured to adsorb an acid gas contained in an acid gas containing gas to recover the acid gas in accordance with supply of electrons from the counter electrode to the working electrode in response to an application of a first voltage between the working electrode and the counter electrode.
