Abstract: A data processing device according to the present application includes a reception unit, a first memory unit, a second memory unit, and a storage unit. The reception unit receives user information relating to a user using a user terminal by being triggered upon an access of the user terminal to an information providing device. The first memory unit stores the user information that is received by the reception unit. The storage unit stores the user information in a management area of a second memory unit that is different for each information providing device that is a trigger for reception of the user information stored in the first memory unit.

Abstract: An intake control device of an internal combustion engine in which an intake path of each cylinder is partitioned into an upper and a lower path and a tumble control valve and an intake pressure control valve are provided to open/close the upper path and lower path respectively. In a given driving condition, the intake air flow velocity in the lower path is increased by closing the tumble control valve, thereby generating a tumble flow in the combustion chamber. In this process, the intake pressure control valve is opened around start of an intake stroke and closed around its end to make intake pressure downstream of the intake pressure control valve higher than upstream of it to increase the difference between upstream and downstream intake pressures in the intake stroke. This increases the intake air flow velocity in the lower path and intensifies the tumble flow in the combustion chamber.
