A coolable component for a streaming engine providing an improved cooling, wherein the coolable component includes an outer wall providing an outer surface adapted to be in contact with a hot fluid like a hot gas stream used in the streaming engine or to be coated with a coating that is adapted to be in contact with the hot fluid, wherein the outer surface is at least partially curved. The coolable component includes at least one cooling channel inside the outer wall adapted to guide a cooling fluid through the cooling channel to cool the outer wall during operation of the streaming engine, wherein the cooling channel is adapted to provide a convection cooling of the outer surface.

A ceiling fan comprising a motor system. The motor system is mounted around a motor shaft. The motor shaft couples to a downrod for suspending the ceiling fan from a structure. The motor shaft and motor are encased by a motor housing. The motor housing comprises hub arms for mounting a plurality of blade holders. The blade holders coupled to a plurality of blades rotatable about the motor during operation.

An airfoil a metal body, a cover panel carried on the metal body, and push fasteners extending through the cover panel and locking the cover panel on the metal body.

The present invention is an airbag device mounted on one side of a vehicle seat in which both ends of a seat-shaped cushion that are opposed in horizontal and longitudinal directions during expansion and deployment are respectively bent a plurality of times and formed into molded parts R1, R2, and is provided with a first holding member 43 that holds the first molded part R1 on one end of either of the ends at least until the start of expansion and deployment and a second holding member 44 that holds the second molded part R2 on the other end at least until the start of expansion and deployment.

An impeller for a centrifugal blower includes at least one blade oriented in a radial direction of the impeller. The blade has an airfoil section with a radially inward end and a radially outward end that are thinner than at least one point between the radially inward end and the radially outward end.

A rotor blade includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.

A ceiling fan assembly including a stator assembly having a non-rotating motor shaft and stator slidably and non-rotationally coupled to the non-rotating motor shaft, a rotor assembly, a first bearing slidably mounted to the non-rotating motor shaft and rotatably coupling the rotor assembly to the stator assembly, and a first spacer located between the first bearing and the stator assembly to fix the sliding location of the first bearing relative to the stator along the non-rotating motor shaft.

A ceiling fan comprising a motor having a rotating blade hub and a downrod mount. The ceiling fan also has multiple blades mounted to the rotating blade hub. The downrod has an upper end configured to mount to a structure and a lower end with a mount motor. The ceiling fan also has multiple studs provided in one of the downrod mount or the motor mount and corresponding openings provided in the other of the downrod mount or the motor mount. The studs are received within the openings to aid in securing the downrod to the motor assembly.

A cross flow fan blade includes an inner edge disposed on an inner circumferential side of a cross flow fan, an outer edge disposed on an outer circumferential side of the cross flow fan, and a base part formed between the inner edge and the outer edge. The base part has a pressure face and a negative pressure face. A thickness of the inner edge is larger than 1.5 times a thickness of the outer edge. An interval between the pressure face and the negative pressure face in a direction perpendicular to the pressure face is a thickness of the base part. A maximum thickness position of the base part is closer to the inner edge than to the outer edge. When a blade chord length is L and a maximum thickness of the base part is tmax, tmax/L≤0.094, and a range of tmax/L≤0.08 is excluded.
