Abstract: An electronic device capable of maintaining a high level of operability and which prevents damage to the keyboard and other input systems when converted from a laptop PC to a tablet PC. The electronic device includes a main body part having a keyboard and a display part having a display. The main body part and the display part may rotate from a 0-degree position where the display and the keyboard face each other up to a 360-degree position where the back faces of the display and the keyboard face each other through a 180-degree position where the display and the keyboard are parallel with each other while facing the same direction. The electronic device includes an upper leg portion that can advance and retreat from an upper face of the main body part in response to rotational movement of the display part from the 180-degree position to the 360-degree position.

Abstract: The invention broadly contemplates an apparatus that makes it possible to easily lift up and open a notebook type computer cover irrespective of a weight of the cover and stop the cover at a predetermined opened/closed position. A portable electronic apparatus includes: a main body provided with an input operating portion, a cover provided with a display unit, a hinge mechanism including a rotary shaft fixed to the cover and a support member fixed to the main body. The apparatus includes an electromagnetic mechanism having a permanent magnet and an electromagnet, in which the permanent magnet and the electromagnet are disposed with respect to the rotary shaft so that when the current is applied or not applied to the electromagnet, a repulsive or attractive force is generated which allows the rotary shaft to be in a rotatable state, and thereby allow an opening/closing torque to act on the cover.

Abstract: Provision of an extension-type battery pack which is improved in safety thereof against dropping and impact application. Although a battery pack is susceptible to damage caused by an impact since partial battery cells are located outside the outline of a notebook PC when it is mounted on the notebook PC, the battery pack is provided with a partition wall structure including an air space and a fireproof wall formed of a material which does not melt at a temperature of combustible gas discharged from a gas discharge valve of the respective battery cells. The material of the fireproof wall is preferably mica or the like. The partition wall structure can be provided between an inside battery compartment and an outside battery compartment of the battery pack or can be provided among other battery cells. This prevents fire spreading to other battery cells even if high-temperature combustible gas is discharged from a battery cell damaged by an impact or the like.

Abstract: In the context of a notebook computer, multiple battery safety measures in the computer, battery pack, and individual battery cells. These battery packs include industry standard safety mechanisms as well as additional safeguards designed to increase safety. The additional safeguards can be categorized in the following ways. The first safeguard deals with multiple, independent levels of battery monitoring. The second safeguard employs abnormal condition detection methods. The third safeguard deals with improvements to mechanical and thermal design.
