A method for manufacturing a microfluidic device includes following steps. A mold made of a glass material is provided. The mold has at least one hollow mold cavity and at least one blocking wall around the hollow mold cavity. The mold is disposed on a silicon substrate, which includes a formation surface corresponding to the hollow mold cavity and a microfluidic male mold protruding from the formation surface.

Methods for optimizing fiber placement programming for use in automated manufacture of steered-fiber composite laminates. The optimization methods are implemented in software capable of optimally translating steered-fiber laminate definitions in fiber placement code for manufacturing steered-fiber laminates without overlaps. The optimization is set up to take into account manufacturing constraints, such as minimum cut length, minimum steering radius, and fiber straightening due to steering. This software includes both geometry and optimization and will take the aforementioned issues into account by optimizing the direction of lay down and the location and sequence of cutting and adding individual tows.

A motor of the present invention includes a stator having windings. The stator includes: a cylindrical outer member; a mold resin portion that molds the windings with a resin; and a stress non-transmitting portion provided between the mold resin portion and the outer member so as not to transmit stress to the outer member due to shrinking of the mold resin portion or reduce the amount of transmitted stress.
