Abstract: A hinge which may be used for example in portable electronic devices may raise the upper body of the device from the lower body in response to rotation of the upper body about the hinge. The need to include a half-pipe section on the upper surface of the lower body maybe avoided. Thus more internal space of the lower body may be used without having to accommodate for the hinge. In an exemplary embodiment, the hinge may include a cam surface. The cam surface may be configured to shift a longitudinal axis of the hinge on response to the rotation of the upper body. In some embodiments, the shift of the longitudinal axis may be away from the lower body allowing a rear edge of the upper body to move across a rear edge of an upper surface of the lower body.

Abstract: A heat sink, cooling member, semi-conductor substrate cooling system, computer and method for providing sufficient cooling performance through a heat sink is provided. In part, there is provided a heat sink having a radiating portion for diffusing the heat conducted from a heat source and a blasting fan for blasting air to a duct-like structure formed by the radiating portion. Moreover, rates of airflows in the duct-like structure are averaged so that air circulates through all portions in the duct-like structure by forming a high-wind-pressure portion and a low-wind-pressure portion having wind pressures different from each other when air is blasted by the blasting fan in the duct-like structure and using the high-wind-pressure portion as a high-density area having a high arrangement density of radiating fins compared to the low-wind-pressure portion.
