    • To provide a vehicular two-wheel drive and four-wheel drive switching system the power consumption of which can be reduced. A vehicular two-wheel drive and four-wheel drive switching system is provided with a switching unit for transmitting power or disconnecting the transmission of power. The switching unit is provided with a driving shaft connected to the drive side, a driven shaft fitted to the driving shaft via an annular clearance gap. A plurality of connecting/disconnecting members are provided in a clearance between the driving shaft and the driven shaft for connecting or disconnecting the driving shaft and the driven shaft by being fitted or disconnected to/from respective opposite surfaces. A switching mechanism is provided for selectively positioning the connecting/disconnecting members in a position in which the driving shaft and the driven shaft are connected and in a position in which the driving shaft and driven shaft are disconnected. A control unit is provided for supplying driving current to the switching mechanism by repeating continuous supply and supply by duty cycle control.

    • A notebook computer 1 is provided with: a casing in which a CPU is accommodated; a heat-dissipating component 37 having a plurality of fins; and a fan 31, and operates such that heat transferred from the CPU to the heat-dissipating component 37 is heat-exchanged with air supplied from the fan 31, and released to the exterior of the casing. The heat-dissipating component 37 is disposed at an air outlet 32b of the fan 31. An opening 35 is formed, between the air outlet 32b and a fan main unit 33, in a fan case 32. First shutter means 39 is provided on a discharge outlet surface of the heat-dissipating component 37. With this structure, increase in cost and weight can be restrained, and dust on the heat-dissipating component can be removed with a simplified structure.

    • An electronic device includes: a casing in which electronic components including a heat-emitting component which emits heat during operation are accommodated; a heat-dissipating component including a plurality of fins to which heat emitted in the heat-emitting component transfers; a fan operable to supply cooling air to the heat-dissipating component; and a cleaning component movable on an end surface of the fins along the side nearer the fan with the cleaning component abutting against the end surface of the fins. In these features, dust on the end surface of the fins can be automatically removed by moving the cleaning component in the case of the spatial orientation of the electronic device being changed. Therefore, an effect of removing heat emitted in the heat-emitting components, by using cooling air supplied from the fan, can be continuously obtained.
    • 电子设备包括:壳体,其中容纳包括在运行期间发热的发热部件的电子部件; 散热部件,其包括多个散热片,散发在所述发热部件中的热量传递给所述散热片; 风扇,其可操作以将冷却空气供给到所述散热部件; 以及清洁部件,其沿着更靠近风扇的一侧在翅片的端面上移动,其中清洁部件抵靠散热片的端面。 在这些特征中,在改变电子设备的空间取向的情况下,可以通过移动清洁部件来自动去除翅片的端面上的灰尘。 因此,可以连续地获得通过使用从风扇供给的冷却空气来除去在发热部件中发出的热的效果。
