  • Patent number: 6989985
    Abstract: An electronic apparatus has a hinge mechanism, which connects a main unit and a display unit. A first shaft of the hinge mechanism connects the display unit to the main unit such that the display unit is rotatable between a closed position where the display unit overlies the main unit and an open position where the display unit is raised up from the main unit. A second shaft of the hinge mechanism is perpendicular to the first shaft and connects the display unit to the main unit so as to be rotatable in a circumferential direction of the second shaft. The main unit has a braking mechanism, which generates braking force that limits rotation of the display unit between the closed position and the open position. The display unit has an engagement member, which is removaly engaged with the braking mechanism.

  • Patent number: 6850407
    Abstract: An electronic apparatus has a first housing, a second housing, a hinge mechanism and an interlocking mechanism. The hinge mechanism couples the first and second housings so that the housings are relatively rotated about first and second axes intersected with each other. An interlocking mechanism decreases a rotational resistance between the first and second housings about one of the two axes, while the first and second housing are relatively situated to each other at a position of the rotation about the other axis.

  • Publication number: 20050007735
    Abstract: An electronic apparatus is provided with a circulating path used to circulate liquid coolant between a heat-receiving portion thermally connected to a CPU that generates heat and a heat-radiating portion that radiates heat generated in the CPU, so that the heat generated in the CPU is transferred to the heat-radiating portion by the liquid coolant. A reserve-tank is disposed in the circulating path and stores a portion of the liquid coolant for a reserve function. The circulating path includes a first tube to return the liquid coolant to the reserve-tank, and a second tube to lead the liquid coolant out from the reserve-tank. The second tube includes an inflow portion through which the liquid coolant inside the reserve-tank flows in, and the inflow portion is positioned at or near the center inside the reserve-tank.
