Abstract: In a small-sized computer of a natural air-cooling type, a high-temperature radiator promotes natural convection so as to increase a quantity of heat radiation and to raise the allowable limit of heat generation of LSI chips, thereby improving the processing speed of the computer. For this purpose, a casing and fins are utilized as heat radiators at relatively low temperatures of about 40.degree. C. which are safe even if they are touched by an operator's hands. On the other hand, the high-temperature radiator set at about 50.degree. to 60.degree. C. is provided inside of the casing, thus preventing the operator's hands from touching it directly. Heat generated by the LSI chips and so forth is transmitted to the high-temperature radiator through heat conduction or the like, and heat exchange is performed between the high-temperature radiator increased in temperature and the air introduced into the casing, in order to promote natural convection inside of the casing.

Abstract: A portable computer having a standby power mode of operation has a bay for receiving a portable removable disk drive. The drive has a pair of slots engageable with parallel guide rails in the receiver, and a notch engageable with a retractable latch normally biased in the direction of the notch. A switch adjacent one of the rails generates a standby signal for the computer whenever the drive is inserted into the bay or moved in the ejection direction after installation. An ejector mechanism retracts the latch and an auxiliary locking pivot to release the drive for removal. The ejector also provides an ejection force which moves the drive a sufficient distance externally of the bay to permit the drive to be grasped by the user for complete removal. A grounding contact engageable with a similar contact on the drive provides a static discharge path for the drive prior to electrical interconnection with the computer.
