Abstract: Disclosed in the present disclosure are a display device and a display apparatus. The display device includes: a first substrate and a second substrate opposite to the first substrate, a light-emitting pixel array between the first substrate and the second substrate, a reflective plate at a backlight side of the light-emitting pixel array, and a polarization conversion structure and a polarization filtering structure which are successively arranged at a light emission side of the light-emitting pixel array; the polarization filtering structure is for filtering light emitted from the light-emitting pixel array side to the polarization filtering structure, so that target polarized light is transmitted, and non-target deflected light is reflected back; and the polarization conversion structure is for converting transmitted circularly polarized light into linearly polarized light, or converting transmitted linearly polarized light into circularly polarized light.

Abstract: A pump includes an axial inducer. The axial inducer includes a housing that has an internal surface that defines an axial fluid passage. A rotor is disposed about a central axis in the fluid passage. The rotor includes at least one blade that defines at least one blade tip. The internal surface of the housing defines a plurality of grooves adjacent the at least one blade tip. The grooves are elongated in a circumferential direction.

Abstract: A commutator has a conductive layer, a segment layer and an insulating layer separating the conductive layer and the segment layer. The segment layer includes multiple commutator segments. A mounting hole is defined along an axis of the commutator passing through the conductive layer. The three-layer structure of the commutator forms a capacitor having an increased confronting area and reduced inter-plate distance. The capacitor thus has a greater capacitance and hence greater EMI absorbing capability, making it possible to reduce EMI emissions without additional EMI reduction components outside the commutator. A rotor and a motor employing the commutator are also disclosed.

Abstract: A brake device for a dual bearing real, includes a one-way clutch, an operating member and a pressing member. The one-way clutch has an inner race, an outer race and a rolling element, and receives rotation of a spool shaft only in a fishing-line casting direction through the outer race. The outer race is disposed on the outer peripheral side of the inner race, and is rotatable with respect to a reel unit. The rolling element is disposed between the inner race and the outer race. The operating member is disposed on the outer peripheral side of an end of the spool shaft, and is engaged with the reel unit so as to be movable in a spool shaft direction. The pressing member is configured to press the outer race. The outer race is restricted from moving oppositely to the pressing member in the spool shaft direction.

Abstract: A motor assembly for a window lift mechanism has a motor and a gearbox. The motor includes a stator having a metal housing, and a rotor with a commutator, rotatably received in the housing. An end cap assembly is connected to the housing. The end cap assembly includes a plurality of brushes making sliding contact with the commutator, a plurality of connecting pieces for connecting an external power source, inductors connected between the brushes and the connecting pieces, and shielding layers cladding the inductors and electrically connected to the housing.

Abstract: An inducer rotor rotatably mountable in an inducer for pressurizing fluid traveling through the inducer. The inducer rotor includes a hub. The hub has a central axis and a plurality of blades extending radially outward from the hub. Each blade extends from a root portion that is next to the hub, to a tip portion that is opposite the root. The rotor further includes a shroud extending circumferentially between each pair of adjacent blades within the plurality of blades. The shroud has an inner surface facing the central axis and an outer surface that is opposite the inner surface. Between the inner and outer surface of the shroud is defined a thickness. The shroud thickness varies circumferentially around the shroud.
