  • Publication number: 20060146495
    Abstract: A fan housing of a fan unit includes a housing wall standing from the surface of a printed circuit board. The printed circuit board serves to establish the fan housing in cooperation with the housing wall. The fan housing further includes a ceiling wall connected to the housing wall. The ceiling wall extends along a datum plane parallel to the surface of the printed circuit board. A high speed airflow can be generated within the fan housing. The airflow promotes the heat radiation from the printed circuit board. An electrically conductive wiring pattern extending over the surface of the printed circuit board may further promote the heat radiation from the printed circuit board.

  • Publication number: 20060034047
    Abstract: A portable computer includes a portable computer body having an upper surface, a lower surface and a lower front edge thereof. An add-on battery is detachably mounted on the lower surface of the portable computer body and has a wedge-shaped portion corresponding to a wedge-like space which is defined between the lower surface of the portable computer body and a surface on which the portable computer body is placed, when the portable computer body is placed to be inclined about the lower front edge of the portable computer body. The portable computer body is, when it is equipped with the add-on battery, inclined in such a manner that the upper surface of the portable computer body is lower at a front edge thereof.

  • Patent number: 6989986
    Abstract: Information processing apparatus, particularly a plane display unit used both for a display and an inputting device is required to be small-sized when it is attached to a housing. For this purpose, a flat rectangular plane display unit is attached to the housing by means of fixing members at three positions; left and right sides and an upper central positions. The left and right sides of the plane display unit are fixed to a back cover with screws using the fixing members and the upper central position of the plane display unit is clamped by the fixing member to be fixed to the housing.

  • Publication number: 20060014441
    Abstract: A LAN connector is connected with a LAN cable connector inserted thereinto. The LAN connector comprises a flexible portion formed outside a modem-cable-connector occupied space within a housing having a size accommodating the LAN cable connector being inserted thereinto, and a stopper portion formed within the modem-cable-connector occupied space. The stopper portion is displaceable together with the flexible portion. When the modem cable connector is inserted into the housing, the flexible portion is not pushed and bent by the modem cable connector, and the stopper portion stops the modem cable connector. When the LAN cable connector is inserted into the housing, the flexible portion is pushed and bent by the LAN cable connector so as to cause the stopper portion to be withdrawn out of the modem-cable-connector occupied space.

  • Publication number: 20050207124
    Abstract: An intake opening is defined in a printed circuit board inside a fan cover mounted on the printed circuit board. The intake opening has a particular extent inside the fan cover. This intake opening contributes to improvement in the cooling efficiency of a fan as compared with a conventional intake opening. Moreover, the intake opening allows a sufficient space to remain on the front and back surfaces of the printed circuit board inside the fan cover. Electronic components and/or wiring patterns may be disposed in the space. This contributes to disposition of electronic components and/or wiring patterns at a higher density on the printed circuit board.
