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.

Abstract: Battery cells may be heated safely and reliably. A power supply device includes a battery block (10) including battery cells including positive and negative electrodes at both ends, lead plate (2) connected to the positive and negative electrodes of the battery cells to electrically connect the battery cells, and a sheet heater (3) configured to heat the battery cells. The sheet heater (3) is thermally coupled and placed on one surface on the negative electrode of the battery cell via one of the lead plates (2).

Abstract: Provided are a method for designing a vane, which can reduce peaks of secondary flow losses appearing locally in secondary flow regions and a vane obtained by the designing. The method for designing a vane includes: a step of determining a base vane formed by stacking profiles having airfoil shapes in a spanwise direction along a stacking line which is configured as a smooth curved line having no inflection point or a straight line; and a step of changing the stacking line of the base vane to a smooth wavy curved line which waves in an axial direction of a fan, a compressor or a turbine and has no elbows.

Abstract: Provided is a blade capable of optimizing an outflow angle in substantially the entire hub region and tip region, particularly in a blade-end-side hub region and a blade-end-side tip region. The blade includes: a base blade part; a suction-side elevated portion provided on a suction surface near a trailing edge in at least one of the blade-end-side tip region and the blade-end-side hub region of the base blade part; and a pressure-side elevated portion provided on a pressure surface near the trailing edge in at least one of a midspan-side tip region and a midspan-side hub region of the base blade part. An airfoil at each spanwise position where the elevated portion is provided is such that a trailing-edge curve of a base airfoil is changed to a modified trailing-edge curve.

Abstract: A metal plate coated with a lubricating resin is coated with a lubricating resin having a modified polyamide ({circle around (1)}) and a crosslinking curing agent ({circle around (2)}) of the modified polyamide ({circle around (1)}) on at least one side face of the metal plate. At this time, the compounding ratio of the modified polyamide ({circle around (1)}) and the above-described crosslinking curing agent ({circle around (2)}) is preferably (60:40) to (15:85) by mass ratio converted to solid content. Furthermore, according to requirement, an inorganic powder filler ({circle around (3)}) may be added to the resin composition.
