Abstract: An electronic light-emitting device includes a housing. An upper end of the housing has an opening, and a positioning rod is connected to an upper inner side of the housing. The positioning rod is mounted by a holder via a through hole. An upper end of the holder has a flame decoration sheet extended to expose outside the opening. A light-emitting unit is provided at the inner side of the opening of the housing to radiate the flame decoration sheet. A lower inner side of the housing has a swinging member and a driving member. A lower end of the housing is connected to a seat. The swinging member has a magnetic element, and an extension section at an upper end thereof that touches and pushes the lower end of the holder. The driving member is disposed to correspond to the magnetic element.

Abstract: A system for testing hard disks includes a hard disk testing device and a computer. The computer has a mainboard and a key-press controller. The hard disk testing device connects with the mainboard and includes: a hard disk interface configured for connecting one or more hard disks to be tested to a south bridge of the mainboard; a key-press panel configured for connecting the key-press controller of the computer, and providing a hard disk testing control interface for users; and a hard disk testing unit configured for testing the one or more hard disks.

Abstract: A spindle structure of a motor rotor is disclosed. An insulating layer is integrally formed between the spindle and the silicon steel pieces of the motor by injection. Two sun plates are integrally formed at the insulating layer and clamp the two ends of the silicon steel pieces. Trenches are formed on the spindle. In the each of the positions that the insulating layer is connected to the sun plates, a rib with a predetermined height is integrally formed for enhancing the stability of the center of gravitation and the magnetic flux, and for enhancing the connection between the spindle, silicon steel pieces and the sun plates. Furthermore, two ladder shape buckling portions are formed at the insulating layer and outside the sun plates for positioning a fan.

Abstract: A rotor structure for a motor includes a rotor body having two sides, two sun plates each attached to one of the two sides of the rotor body and each having a copper wire wound thereon, and two end caps each secured to a corresponding one of the two sun plates and each enclosing the copper wire therein. Each of the two end caps includes a plurality of plugs each inserted into the respective sun plate for securing the end cap to the respective sun plate.
