Abstract: The present disclosure provides for a computer chassis in which a base component can have a plurality of guide slots. A top cover of the chassis can have a plurality of guide pins where each guide pin is configured to fit into a guide slot. The base component and top cover also comprise an elastomer positioned adjacent to at least some of the guide slots. The elastomer pushes against a guide pin to force the guide pin into the guide slot. The elastomer therefore reduces or eliminates a gap between the base component and the top cover.

Abstract: A micro-motor includes a base, a rotor and a retaining member. The base includes an axle tube. The rotor includes a rotary member and a support member arranged between the rotary member and the base. The rotary member has a central hole where the axle tube of the base extends. The retaining member is mounted on the base and surrounds the rotor. One end of the retaining member, which doesn't couple to the base, extends towards the axle tube to form a retaining portion. The retaining portion is within a rotational area of the rotor in an axial direction of the axle tube. The rotor is arranged between the retaining portion and the base. Accordingly, the retaining member can retain the rotor to prevent departure of the rotor from the axle tube of the base and the central structure of the micro-motor is effectively simplified.

Abstract: A safe and high-brightness LED lamp consists of a lampshade, a bulb mounting base, an LED module and a circuit board. The lampshade and bulb mounting base construct an inner space, which is allowable to store said LED module; the LED module consists of a heat-radiating block, an LED lamp panel and a reflective wall, where such LED lamp panel can be flat nestled up against the heat-radiating block at one end. Moreover, such reflective wall can be coupled with the LED lamp so that the said inner space can be partitioned into one light source refractive space and one flowing space for airflow thereof. Furthermore, an electrical fan is installed outside the heat-radiating block.

Abstract: Provided is the design and fabrication of the novel bounce drive actuator (BDA) for the development of a new-type micro rotary motor. Although the scratch drive actuator (SDA) micro motor has been developed more than one decade, such device has limited commercial applications due to its shorter lifetime, high power consumption and sudden reverse rotation. In contrast, present invention proposes an innovative BDA micro rotary motor with different actuating mechanism and improved performance. Several significant investigations shown in this research present that the length of the SDA-plate is longer than 75 ?m and the plate length of the BDA is less than 75 ?m. Under the same driving power and frequency with SDA-based micro motor, the BDA-based micro rotary motor exhibited a consistent “reverse” rotation and a higher speed.
