Abstract: A vehicle door control device is provided to a vehicle including a door and a drive device. The vehicle door control device executes door control processing when the door moves in a closing direction from a stopped state in a state where a closing operation command signal for commanding a closing operation of the door is not received. In the door control processing, the vehicle door control device executes a braking mode, in which a braking force is applied to the door by regenerative braking action of a motor, when the door opening degree is less than the determination opening degree, and executes a closing operation mode, in which the door performs the closing operation such that a moving speed of the door is constant, when the door opening degree is equal to or greater than the determination opening degree.

Abstract: A store management system includes: an acquisition unit that obtains a face image of a customer from an imaging apparatus that captures the face image of the customer at a timing at which the customer intends at least one of to enter a store, to make payment, and to leave the store; a notification unit that notifies the customer that the face image is to be obtained or is obtained by the acquisition unit; and a permission unit that permits the customer at least one of to enter the store, to make payment, and to leave the store on condition that the face image is obtained by the acquisition unit and that the customer is notified by the notification unit. It is thus possible to suitably manage the customer's entrance into the store or the like.

Abstract: A clothes drier, in which a drum having an opening for charging clothes therethrough, an air intake port and an air exhaust port is rotatably supported in a cabinet. The air heated by a thermistor having a positive temperature coefficient is fed into the drum. This heat generating body tends to lower the heating value as the temperature rises, thus dispensing with a protective or safety means such as a thermostat.
