Abstract: Disclosed is an information processing apparatus comprising a housing (4), a magnetic disk drive unit (6), a sensor (8) and a control unit (10). The sensor (8), which is installed between the housing and the magnetic disk drive unit, detects an external force acting on the housing or a distortion caused in the housing by dint of the external force. The control unit (10) retreats a magnetic head (14) of the magnetic disk drive unit to a retreat area when the external force or the distortion, detected by the sensor, exceeds a predetermined level.

Abstract: An information processing device includes an acceleration sensor that detects an acceleration; a processor that is coupled to the acceleration sensor and configured to: cause a storage that is included in the information processing device to execute crash-proof processing based on the acceleration detected by the acceleration sensor, and cause the storage to terminate the crash-proof processing when the processor detects that an external device is mechanically coupled to the information processing device.

Abstract: A shield structure for information technology equipments includes an opening part provided in a portion of the shield structure and a lid covering the opening part. A signal ground line is provided on a printed circuit board accommodated in the enclosure. An electric connection material extends between the lid and the signal ground line of the printed circuit board and has at least a surface formed by an electrically conductive material. The electric connection material is in contact with the signal ground line of the printed circuit board.

Abstract: A data bus circuit connects a south bridge driven by a first voltage and a bay driven by a second voltage. The first voltage and the second voltage are different. The data bus circuit includes a data bus that electrically connects the south bridge and the bay, and a Thevenin termination circuit that is arranged on the data bus at a point. The Thevenin termination circuit maintains a voltage at the point substantially equal to the first voltage.
