Abstract: A method for manufacturing a motor includes the following steps of: providing a substrate with an opening and a bushing; disposing the bushing within the opening of the substrate; providing a cushioning material disposed between the substrate and the bushing by injection molding.

Abstract: A connecting mechanism is provided for connecting a power adapter and an electronic device. The connecting mechanism includes a first connecting part and a second connecting part. The first connecting part is connected with the power adapter, and includes a first magnetic core, a first winding and a first magnetic element. The second connecting part is connected with the electronic device, and includes a second magnetic core, a second winding and a second magnetic element. The first magnetic element and the second magnetic element are aligned with and magnetically attracted by each other, so that the first connecting part is fixed onto the second connecting part and electromagnetic coupling between the first winding and the second winding is produced.

Abstract: An axial flow fan with a plurality of segment blades is described. The axial flow fan has a base, a hub and a plurality of blade units. The hub is mounted on, or pivots on, the base and supports the blade units. Each of the blade units is connected to a periphery of the hub and extends radially outward from the base has a plurality of segment blades. A segment space between the segment blades reforms a boundary layer of fluid passing over the segment blades and reduces the thickness of the boundary layer on the blade surfaces. As a result, the separation between the blade surfaces and fluid is avoided to maintain a laminar flow of the fluid adjacent to the segment blades.

Abstract: An automatic testing system. A sampling and converting device obtains a plurality of electronic parameters from a tested device and transforms them into a plurality of digital signals. A microprocessor receives the digital signals and performs various short-circuit tests, over-current tests and over-voltage tests in a specific sequence.

Abstract: A magnetic coupling power transmission apparatus for optical disk drive includes a motor with a magnetic conductive member attached to its spindle and a shaft for driving the optical disk drive having a magnetic inductive member mounted thereon. The magnetic conductive member has a plurality even number of north and south pole magnets alternatively located thereon. The magnetic inductive member has a plurality even number of south and north pole magnets located thereon to mate against the magnetic conductive member. The magnetic conductive member is spaced from the magnetic inductive member to produce magnetic attraction between the north and south poles between the two members. Motor rotation power may be transmitted through this magnetic coupling to the optical disk smoothly and with less noise than conventional gear train engagement.
