    Abstract: A charging system includes three charging stands, an exhaust heat pipe provided underground, and a heat utilization device that utilizes exhaust heat. The charging stand has an opening and an exhaust heat port. The exhaust heat port is connected to an exhaust heat pipe. Cooling air taken in through the opening exchanges heat with a power supply circuit of the charging stand, and is then discharged from the exhaust heat port into the exhaust heat pipe. The temperature of the cooling air discharged into the exhaust heat pipe is raised by heat exchange with the power supply circuit. The cooling air flows through the exhaust heat pipe and is supplied to a heat utilization device.

    Abstract: A ventilation apparatus includes an air supply blower; an exhaust blower; a sensor that detects air quality; and a control unit that controls air flow rates. Upon receipt of an instruction for an operation based on an air flow differential indicating a difference between a specified supply air flow rate and a specified exhaust air flow rate, for a first blower that is either the air supply blower or the exhaust blower, the control unit obtains a first air flow rate from air flow rate setting information establishing a relationship between an air quality level and the air flow rates and controls the first blower at the first air flow rate, and for a second blower, the control unit computes a second air flow rate by using the first air flow rate and the air flow differential and controls the second blower at the second air flow rate.

    Abstract: A duct unit is disposed inside a housing of an image forming apparatus and used. The duct unit includes an airflow generation unit, a duct, and a first holding portion and a second holding portion. The duct has a shape in which a center of an intake port and a center of an exhaust port are shifted from each other. The first holding portion and the second holding portion are provided at different positions with respect to the duct so as to be able to hold the duct unit with respect to the housing in a first posture and a second posture.

    Abstract: When a main body case is viewed from below, an antenna is within a rectangular/square area defined by first to fourth points. An opening edge of a first opening includes: a first edge linearly along a first direction; and a second edge linearly along a second direction perpendicular to first direction, first point is defined as an intersection of a first straight line and a second straight line, first straight line includes first edge, and second straight line includes second edge. Second point is defined as a point apart from first point in first direction by a distance that is half prescribed wavelength. Third point is defined as a point apart from second point in second direction by a distance that is half prescribed wavelength. Fourth point is defined as a point apart from first point in second direction by a distance that is half prescribed wavelength.
