  • Patent number: 11945285
    Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

  • Patent number: 11718157
    Abstract: An air discharge device is configured to discharge an air flow. The air discharge device includes a main hole for discharging an air flow as a working air flow, an auxiliary hole provided around the main hole to discharge a support air flow, and a vortex suppression structure configured to suppress development of vortices generated in a velocity boundary layer of the working air flow at a downstream side of an outlet of the main hole. This vortex suppression structure is configured to make a central portion of the thickness of the velocity boundary layer of the working air flow at the downstream side of the outlet of the main hole to be closer to a mainstream of the support air flow, at the downstream side of the outlet of the main hole.

  • Publication number: 20210245575
    Abstract: An airflow generating device includes an airflow generating portion, a duct, and a controller. The airflow generating portion is configured to generate an airflow. The duct is configured to guide the airflow to a blowing outlet through which the airflow is blown out toward a passenger in a vehicle cabin. The controller is configured to cause the airflow to be intermittently blown out through the blowing outlet by controlling a frequency of a pulse voltage applied to the air flow generating portion and a duty ratio of a pulse width to a pulse period of the pulse voltage. The controller is configured to control the duty ratio and the frequency of the voltage such that the airflow is blown out through the blowing outlet at a speed between a predetermined lower limit, inclusive, and a maximum lower limit, non-inclusive, which is greater than the lower limit.

  • Publication number: 20210016634
    Abstract: An air discharge device includes a duct that defines a flow passage through which a working air flow to be discharged passes, and a hole forming member defining an air discharge hole as an outlet of the working air flow. The hole forming member has a vortex generation structure configured to generate an auxiliary vortex having a vortex characteristic including a vortex rotation direction and a vortex axis direction. The vortex characteristic of the auxiliary vortex is different from that of a lateral vortex generated by the working air flow at a downstream side of the air discharge hole. The vortex generation structure is configured in the hole forming member so that the auxiliary vortex collides with the lateral vortex in a state where at least one of the vortex rotation direction and the vortex axial direction of the vortex characteristic is different from that of the lateral vortex.

  • Publication number: 20210017977
    Abstract: An air blowing device includes a duct portion and a passage variable device. The duct portion forms a main passage through which an air flow passes, and an outlet is defined downstream of the main passage to blow out the air flow. The passage variable device is configured to change a passage area of the main passage so that the air flow becomes a pulsating flow and is blown out from the outlet.

  • Patent number: 9513841
    Abstract: When execution of a program is started, in a case where a memory region used by the program when the execution of the program was stopped is usable, the past execution conditions of the program to be reproduced are enabled without reading in data disposed in the memory region used by the program, which data was stored when the execution of the program was stopped. When the execution of the program is stopped, a stop and end managing section performs control to store at least a part of the data disposed in the memory region used by the program in association with the program while retaining the data.
