Abstract: Provided is a shopping cart capable of simplifying equipment of a storage area of the shopping cart. A shopping cart allowed to be nested in a front-rear direction, including: a cart body; a battery configured to supply power to an electronic device attached to the cart body and displayed commodity information read by a reading device; a power receiving portion provided on a front side of the cart body and configured to be electrically connectable to an external power supply; and a power transmitting portion provided on a rear surface side of the power receiving portion and configured to supply power to a power receiving portion of another shopping cart nested in the shopping cart. Each of the power receiving portion and the power transmitting portion is provided with a magnet configured for holding a relative position.

Abstract: Provided is a refrigerating machine oil composition for a mixed refrigerant comprising difluoromethane, the composition comprising a polymer (A) below and an ester (B) of polyhydric alcohol(s) with aliphatic monocarboxylic acid(s). The polymer (A): a polymer which is obtained by polymerizing monomer(s) consisting of at least one monomer of monosubstituted ethylenes and disubstituted ethylenes, and in which a ratio of a monomer represented by the following general formula (I): wherein R1 represents an alkyl group having 1 to 14 carbon atoms, R2 represents hydrogen or an alkyl group having 1 to 4 carbon atoms, and the sum of carbon numbers in R1 and R2 is 2 to 14, is 75 to 100% by mass based on a total mass of monomers constituting the polymer.

Abstract: An information processing apparatus includes: a detecting unit that detects a change of a real IP address of the information processing apparatus; and a change notification transmitting unit that generates, when the detecting unit detects the change of the real IP address of the information processing apparatus during communication with a communication partner, a change notification packet, and transmits the generated change notification packet to the communication partner. The charge notification packet includes a header portion and a data portion. The real IP address before the change is included as a source IP address in the header portion of the charge notification packet, and a real IP address after the change is included in the data portion of the charge notification packet.

Abstract: An imaging device includes a camera unit having an imaging element in which subject light which has passed through a shooting optical system is formed to output an image signal, a main body unit from which the camera unit is detachable, the main body unit having a display monitor displaying a subject image on a screen by input image data in which the image signal is processed, and a communication unit which enables bidirectional communication of the camera unit and the main body unit in a state in which the camera unit is removed from the main body unit.
