  • Patent number: 8356656
    Abstract: A heat dissipation device and a heat dissipation method are provided. The device is disposed in a case having a first opening and a fan for generating a first cooling air flow. The device includes a heat dissipation element and an air-guiding plate. The heat dissipation element has a first region and a second region, and the first cooling air flow flows from the first region towards the second region. The air-guiding plate is disposed in the first region of the heat dissipation element and used for reducing a cross-sectional area of the first cooling air flow flowing in the first region along a flow direction of the first cooling air flow, so as to draw air outside the case into the second region via the first opening to generate a second cooling air flow, thereby lowering a temperature of the case located below the heat dissipation element.

  • Patent number: 7836796
    Abstract: A screwing device includes a holder, an interaction unit and a screwing unit. The holder has a rotation axle. The interaction unit is connected to the rotation axle and has an interaction ring. The screwing unit has a plurality of screwing elements and interacts with the inner peripheral surface of the interaction ring. When the holder rotates along a screwing direction, the interaction ring also rotates along the same screwing direction and drives the screwing unit to rotate along the same screwing direction.

  • Publication number: 20100053409
    Abstract: An electronic device includes a casing, an image capturing module, and a biaxial hinge element. The biaxial hinge element has a first hinge and a second hinge. Two ends of the first hinge protrude from two sides of the biaxial hinge element thus to be pivotally connected to the casing, respectively. The second hinge is pivotally connected to the image capturing module.

  • Publication number: 20070221735
    Abstract: An optical reading device is disclosed, in which the size and weight thereof are reduced, and the shock resistibility of the spindle motor thereof is improved. The optical reading device comprises a casing and an optical reader, wherein the optical reader thereof is received inside the casing. The optical reader includes a first portion, a second portion, and an optical fiber. The first portion is mounted inside the casing, while the second portion is mobile inside the casing. The optical fiber connects with the first portion and the second portion respectively, which enables the light to be emitted from the light source of the first portion and to be transmitted to the second portion and the data storage medium thereof. Hence, by the arrangement of the units illustrated, the weight of the optical reader device is reduced, and the shock resistibility of the optical reader thereof is improved as well.

  • Publication number: 20070187070
    Abstract: A heat-sink with slant fins is provided. The slant fin may change the area of the cross-section along the direction of winds blowing. Due to the fact that the area is decreased, the flow speed increases. That solves the retained hot air resulted from a remote distance from the fan.
