  • Publication number: 20130336805
    Abstract: A fan control device includes a PWM generating circuit, a PWM switching circuit, and a switching instructing unit. The PWM generating circuit generates an arbitrary signal controlling rotation of a fan for cooling an MXM card. The PWM switching circuit is located between the MXM card and the fan, and switches output to the fan from the arbitrary signal generated by the PWM generating circuit to a signal output from the MXM card. The switching instructing unit issues a switching instruction to the PWM switching circuit at predetermined timing. Consequently, the fan control device can appropriately control the fan for cooling a heat-generating component.

  • Publication number: 20050259015
    Abstract: The electronic equipment according to the present invention is adapted to be operated by an operator in facing positional relationship therewith. This electronic equipment includes a housing accommodating an electronic circuit for operation and a high-frequency circuit for wireless communication related to the operation, and a dielectric antenna connected to the high-frequency circuit. The dielectric antenna is mounted on the rear surface of the housing near a lateral end thereof. Since the electronic circuit for operation and the high-frequency circuit for wireless communication are provided in the housing, it is not necessary to connect a personal computer and a mobile telephone by a cable according to predetermined specifications as in the prior art, so that it is possible to provide electronic equipment which can be easily used as a mobile terminal.
