Abstract: An attaching and detaching apparatus includes a main mounting plate to which a main mounting object is to be mounted, an attachment mounting plate to which an attachment mounting object is to be mounted, and a connecting member between the main mounting plate and the attachment mounting plate. A protrusion projecting toward the connecting member is formed on the main mounting plate. A hole into which the protrusion fits is formed on the connecting member. A first contact surface in the shape of a surface of revolution is formed on the protrusion. A second contact surface in the shape of a surface of revolution is formed on the inner surface of the hole. The first contact surface and the second contact surface are in contact with each other with the central axis of the protrusion coinciding with the central axis of the hole.

Abstract: There is provided a power management device including a load current control unit that sets an upper limit on a load current received from a connected feeding device and controls the load current on the basis of the upper limit, and a determination unit that, when the load current control unit has reset the upper limit to a higher value, determines if the upper limit has exceeded a current capacity of the feeding device on the basis of a voltage drop level of an input voltage. The load current control unit resets the upper limit in increments or decrements of a predetermined value, and the load current control unit, when the determination unit has determined that the upper limit had exceeded the current capacity of the feeding device, controls the load current by resetting the upper limit to a value not exceeding the current capacity.

Abstract: The invention provides a storage medium and a downloading method by which data can be downloaded comparatively simply and efficiently. Program information describing a downloading procedure is stored in a storage medium, and the storage medium is provided in this form to a user. When the user utilizes the storage medium, a procedure that can be executed to perform necessary processing without depending upon an operation of the user can be included in the process from accessing to a server to final downloading of desired content data. Consequently, the necessary number of operations by the user can be reduced as much.

Abstract: Battery information is transmitted from a recording and playback apparatus to a host computer. In the host computer, based on the time for which the operation can be continued, corresponding to the current operating status and the remaining battery level, stored in the battery information, a warning is output, the data of a cache memory is written, data writing prohibition is set, and a forced closing process is performed. With this construction, in a system formed of a recording and playback apparatus, such as a CD-R/RW drive unit, and a personal computer, a proper system operation corresponding to the remaining battery level of the recording and playback apparatus is obtained, and the data recorded on the recording medium is prevented from being destroyed as a result of operation stopping due to, for example, the remaining battery level becoming zero.
