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: The present invention includes a plurality of battery cells, each provided with a gas discharge valve. A housing accommodates the battery cells and has a gas opening. The housing does not melt at an inside temperature of the battery pack increased by gas discharged from the gas discharge valve. A blocking member blocks the gas opening and melts at the inside temperature of the battery pack increased by the gas discharged from the gas discharge valve, breaching the gas opening.

Abstract: A portable computer is disclosed. The portable computer includes a display casing and a system casing. The display casing is configured to accommodate a display. The system casing is configured to accommodate electronic devices. A keyboard assembly is disposed on a surface of the system casing. A palm rest is provided to cover a portion of the surface of the system casing. An intermediate member having design parts covering a peripheral portion of the keyboard assembly and a support portion disposed under the palm rest.

Abstract: A printed circuit board (PCB) for supporting a ball grid array (BGA) includes stress relief features to reduce stress on the solder balls. The stress relief features can be plural lines formed into the PCB along the edges of the BGA, and/or holes formed through the PCB near the corners of the BGA.

Abstract: A ball grid array (BGA) includes straight pins at the corners and if desired along the edges of the array that are engaged with a PCB to reduce stress on the solder balls. The pins can be on the chip substrate of the BGA or on a separate frame that is glued to the chip substrate.

Abstract: The present invention is directed to a computer in which an optional unit such as a unit including a wireless LAN adapter is installable. The computer including at least a computer body, a display, and a keyboard. The invention is also directed to a note book computer 2, which includes a computer body with a keyboard, and a display workable as a lid being opened and closed free with the computer body. In these computers with an optional unit 14, the optional unit is detachably attached to the top of the display, or the optional unit is detachably attached to a portion of the display, the portion being at a side of the display when the lid is closed and being at a top of the display when the lid is opened.

Abstract: To obtain connector connecting structure that makes it easy to connect connectors when a mounted part is mounted in a part-receiving part. In a keyboard unit mounted in a PC body of a notebook PC, a connector implemented on a flexible cable is movably supported through a cushion, which is made of urethane rubber and is fixed on a installation side 14B of the keyboard unit, and a support plate fixed to the cushion. Owing to this, by just mounting the keyboard unit in the PC body, the connector is connected to the connector in the PC body side, and hence connection becomes simple. Therefore, even if the misalignment between the connectors and arises, the connector moves according to an amount of the misalignment, and hence adequate connection can be performed.

Abstract: To provide a portable computer in which a height and angle of a display can be adjusted even in a restricted installation space. In a notebook type personal computer, at an approximately middle portion in a high and low direction of an LCD unit, disposed in a lid, there is provided a hinge, which enables the LCD unit to pivot around a rotation axis crossing perpendicularly with the high and low direction of the LCD unit. This hinge is mounted so as to be movable in the high and low direction of the frame, and is disposed at a higher position than a top of the frame. Thereby, even when rear space where the notebook type PC is installed is restricted, it is possible to adjust the height and angle of the LCD unit, and to make such setting as to enable the display screen to be easily watched.
