A rectangular opening is formed into the plenum of a furnace inlet air duct to extend, at an upward angle, across the rectangular opening, between opposing inner walls of the air duct, and a door is provides for positioning over the duct rectangular opening with the bag filtration element installed therein.

A cover member including an air guiding portion and an HDD including the cover member are provided. The HDD includes: a housing including a base member and a cover member; a spindle motor installed on the base member; a data storage disk mounted on the spindle motor; and an actuator rotatably installed on the base member, and including a read / write head for recording data onto the disk or reproducing data recorded on the disk. The cover member includes an air guiding portion protruding from a bottom surface of the cover member toward a surface of a data storage disk to guide an air flow generated by a rotation of the disk to the outside of the disk, and the air guiding portion has a width that changes along a rotating direction of the disk. Therefore, the air flow generated by the rotation of the disk can be guided outside of the disk by the air guiding portion formed on the cover member, and the air flows fast, and thus, the particles on the disk can be discharged outside of the disk efficiently.

An airbag assembly may include an airbag and an inflator in fluid communication with the airbag. The inflator may have a gas source chamber containing a gas source and a centrifugal flow chamber into which the gas flows from the gas source chamber through a centrifugal flow barrier. As the gas moves through the centrifugal flow barrier, it may be urged to move along a pathway that encircles at least a part of a longitudinal axis of the inflator. The gas may then move toward the longitudinal axis to flow through an orifice of an inward flow barrier. this inward flow may occur at a velocity that is generally too large for entrained particulates. Thus, such particulates may remain in the centrifugal flow chamber. The gas may flow from the orifice into a plenum chamber that releases the gas to the airbag via a plurality of apertures.

The invention discloses a 3D printing method, comprising: step a: providing a liftable printing platform; step b: controlling the printing platform to descend a first predetermined distance value, and spreading metal printing powder on the printing platform; step c : controlling the first laser head to emit a laser with a first predetermined energy value towards the metal printing powder on the printing platform to melt the metal printing powder to form a printing object; step d: controlling the second laser head to rotate around the printing object, and simultaneously controlling The second laser head emits laser light with a second predetermined energy value toward the edge of the printed object on the printing platform to eliminate particles on the edge of the printed object, and the wavelength of the laser light corresponding to the first predetermined energy value is shorter than that specified by the second predetermined energy value. The wavelength of the corresponding laser light is short. Through the above method, the present invention eliminates the particles on the edges of each layer of printed objects each time a layer of printed objects is formed on the printing platform, so that the outer surface of the printed object is not rough and feels good.

The invention relates to a device for aeration and ventilation of a fuel system of a motor vehicle, with a pipe union for connecting the device to the fuel system, the pipe union being connected via a connecting element to a three-way valve via which the pipe union can be fluid-connected alternately to an air inlet opening or an air outlet opening of the device. Furthermore, there is a filter element which is located in the flow path between the air inlet opening and the three-way valve. The filter element, the three-way valve, and the connecting element are accommodated in a common housing. An especially compact and space-saving device is devised by the integration of the three-way valve, connecting element, and filter element into one unit.
